The Hewlett Packard LaserJet P3005 commonly suffers from noises from the back of the printer. These can range from a rhythmic rumbling noise to a loud grinding or clicking noise. It’s caused by either the fuser or the fuser drive gears.
UPDATE
If your LaserJet P3005 is suffering from the worn fuser bush problem, HP will now replace the fuser free of charge until 1st July 2013 if the printer has printed less than 150,000 pages.
See this update:
HP LaserJet P3005 – Noisy, Grinding, Clicking – Update
Removing the fuser and drive gears for inspection is fairly easy:
- Open the rear door and pull it open past it’s stops
- Remove two screws
- Open, or remove, the paper tray
- Open the flap at the bottom of the rear cover, release the two clips at the bottom and pull the rear cover out
- Remove the I/O cover (rear left hand cover)
- Unplug the cable on the left hand side of the fuser from the power supply and remove it from the cable clip
- Unplug the two cables coming from the right hand side ofthe fuser and release one cable clip
- Release the two clips on the duplex inlet guide (black plastic guide) and slide it out of the back of the printer
- Remove four screws and pull the fuser out
- Look inside the left hand side of the printer and you will see four gears
- Unclip the top gear at the back of the printer and the gear below it will slide off
- Remove the plastic clip holding the upper gear further forward in place and slide off this gear and the one below it
Remember how these gears go back onto the printer. When you refit the back cover, fit the top into place first.
Inspect the teeth of the four gears for wear. Sometimes, it’s hard to see, but you might feel a ridge if you slide a small flat blade along the teeth of the gears. If your printer is getting progressively noisier with a rumbling type of sound, it’s probably one or more of these gears worn.
These are the part numbers for the gears:
RU5-0956-000CN, RU5-0957-000CN, RU5-0958-000CN, and RU5-0959-000CN.
Usually, the only gear you will need to replace is the lower one towards the front, the 20 tooth gear RU5-0957-000CN.
Don’t forget to put some grease on the new gears.
There are two things to check on the fuser.
First check the light brown coloured gear. Check the teeth for wear.
Second, check the green plastic bush that the metal shaft rotates in. Push upwards firmly on the gear. If there is excessive movement, the bush is worn. You might also see green powder sitting on the bottom of the fuser. The worn bush will cause a loud clicking noise as the gears are being forced apart as they turn.
The part numbers for the fuser are:
RM1-3740-030CN For 110-127 VAC and RM1-3741-030CN For 220 VAC to 240 VAC.
 RM1-3740-FM3 |
The only other thing you might need if you are reparing the fuser is the fuser film sleeve. These sometimes get torn.RM1-3740-FM3 – Fuser Film Sleeve |
The most common cause of a 10.92 cartridges not engaged error on a Hewlett Packard Color LaserJet 3000 / 3600 / 3800 is broken cartridge locks on the right hand side of the printer. Another possibilty is the slide lever that operates the cartridge locks is broken.
This is the diagnosis of this error form HP’s service manual:

If you follow this procedure, you will end up replacing the DC controller which won’t repair the fault.
What you need to do is slowly open and close the front door. Make sure that the flaps over the front of the print cartridges move. If you look carefully, you should also see the white plastic drives insert into the right hand side of the print cartridges. Also on the right hand side, you should see the levers lock the print cartridges in place.
If you don’t see any of these parts move, the slide lever might be broken. If these parts do move, remove the print cartridges and inspect the plastic levers that lock the cartridges in place on the right side of the printer.
If the cartridge locks are broken, HP will send out an engineer to replace them free of charge, even if the printer is out of warranty. Phone up the warranty support line and tell them the plastic levers that hold the toner cartridges in place are broken. If the printer is out of warranty and they start offering you the paid options, remind them that there’s a service note that covers this fault.
UPDATE
The service note for this fault ended 1st October 2008. You will have to repair it at your own expense now.
If you decide to do the repair yourself, the part numbers are Q5982-67925 which is a set of four cartridge locks and springs and should include instructions. The part number for the slide lever is RC1-6643-020CN.
Be warned, it isn’t easy to replace the cartridge locks or the slide lever. I’m not going to describe how to do it. Instead I’ve provided links below to download the replacement instructions and the service manual.
The service manual is over 17Mb in size and you will only need it to remove the covers. The replacement instructions are only just over 1Mb and you definately need to download and read this.
Follow the instructions closely and pay particular attention to the location of the screws to remove the main drive unit and the gear alignment when reassembling the printer.

A grinding noise and paper jamming at the fuser in a Hewlett Packard LaserJet 5 is more than likely caused by the drive train gear cluster.
Open the rear door on the printer, remove two screws, and then pull the fuser out. Shine a torch into the back of the printer and look at the condition of the gear that drives the fuser. You might see that some of the teeth on this gear are worn or completely missing.
The part number for the drive train gear cluster is RG5-0876-050CN. Hewlett Packard list this part as discontinued but you might be able to find a supplier that can sell you one.
Before you buy this part, check the condition of the fuser. Check the gears and the surace of the heater roller. If the fuser is worn as well, you will need to price this up as well. Bearing in mind that this printer is now over ten years old and probably in need of a complete clean and service , it might be time to buy a new model.
If you decide to replace the part, this is what’s involved:
- Remove the fuser as previously described
- Undo one screw at the back of the right side cover and slide the cover off
- Undo the screw on the memory cover on the formatter assembly and remove the cover
- Remove four screws on the side and two at the back of the formatter assembly and pull the formatter assembly off
- Remove one cable and four screws from the main motor and then lift the motor away
- Remove two screws and the drive train gear cluster will slide out the back of the printer
Before fitting the new part, check that it is lubricated. If not, apply some grease to the gears. Also, make sure it is seated properly before fitting and tightening the screws.

Image ghosting (image repeating itself down the page) on a Hewlett Packard Color LaserJet 2600 when first switched on or after it has been idle for several hours can be cured by a simple firmware update.
Measure the distance between the original image and the repeated image. A measurement of 56.6 mm indicates the fuser needs replacing. Before you buy a new fuser, check the firmware version of the DC Controller.
You can do this by printing out a config page. A configuration page can be printed from the printer control panel (press the green Select button, then press the left (<) or right (>) buttons to navigate to the Reports menu, press the green Select button – press the left (<) or right (>) buttons to navigate to Config report and press the green Select button).
At the bottom of the printed configuration page a line beginning with CPR and then a group of numbers followed by EV= will be shown. The latest DC Controller firmware (1.47) will show as EV=2F.
If the value of EV is lower than 2F, such as 2A, you need to update the DC Controller firmware.
This is the HP description of the fix for this firmware update:
Corrects fuser offset (ghosting) that typically appears on the first print jobs after the printer has been idle for several hours. The offset or ghosting typically appears on the left or right margin but is not limited to those areas.
For some reason, HP have removed the firmware file from their website. You can still find the Mac OS X version on HP by searching for it. You can find the Windows version elsewhere by searching Google for 2600_DCC_FW_Update-14701.exe.
Or you can download the Windows version by right clicking the following link and selecting save:
2600_DCC_FW_Update-14701.exe
This is the version I use, and have used recently, so it works and shouldn’t contain any viruses.
You need to have the printer driver installed on your computer to run this update. Simply run the program and select the printer to update in the box that opens up.
DO NOT POWER CYCLE THE PRINTER during the update process or it may leave your printer in an unusable state.
During the printer firmware update, the liquid crystal display (LCD) on the printer control panel will display “Initializing” and the green and amber LEDs will begin flashing. After several minutes the green and amber LEDs will go solid and the printer will make a noise as if were warming up. The display will then change to ” Turn off then on”. At this point it is necessary to power off the printer and then power on again.
Print out the config page again to confirm that you get EV=2F and your ghosting problem should be fixed.
Update
There are detailed instructions on installing firmware updates on this printer here:
HP Color LaserJet 2600 – Firmware Update
If your Hewlett Packard Color LaserJet 2600 or 2605 prints the red (magenta) faint or not at all, the laser scanner assy needs to be stripped out of the printer and cleaned.
This fault affects the red first and is usually worse on the left hand side of the page. Before you start stripping the printer down, it’s a good idea to try another red (magenta) toner cartridge in it first.
There are two probable causes of this. Firstly, the magenta scanner sits at the bottom of the printer and will tend to collect any stray toner or dust that’s floating about inside the printer. Secondly, there is a fan situated right next to the scanner which will blow any stray dust or toner into it.
This is, briefly, how you remove the laser / scanner assembly from the printer:
- Remove the right cover; remove one screw at the back and pull the right cover off
- Remove the left cover; remove one screw at the bottom of the cover, press the clip in at the front, and pull the cover off
- Remove the nine black screws holding the metal plate on at the back of the printer and remove the metal plate
- Remove the cables connected to the two logic boards except for the flat cable connecting the two boards together and the yellow cables at the bottom of the right hand board
- Remove the cables from the black plastic cable guides
- Remove the L shaped cable guide at the right by pressing in two clips with a small screwdriver and pull the guide out
- Remove the long horizontal guide by sliding it to the left and lifting it away
- 2605 – unclip the cable guide on the left
- Remove the eleven screws from the metal plate with the two logic boards on it and lift the plate away complete with the boards
- Remove the white plastic clip holding the two flat cables from the scanner to the printer chassis
- Remove the three screws from the scanner, two at the top and one at the bottom, and lift the scanner assembly out of the printer (2605 – bottom screw has a metal spring plate covering it)
With the scanner on the bench in front of you, you can now dismantle it ready for cleaning.
Remove one screw and a spring from the front of the scanner and lift off the cover. Remove the long plastic arm which will fall out if you turn the scanner over. Remember how this arm fits.
You will see four 6 cm long red / purple coloured mirrors inside the scanner. Inspect the bottom one. Initially it will look the same as the others. Carefully wipe a small part of it with a cotton wool bud and you will see the difference it makes. It is this thin coating on the mirror that causes the fault.
Carefully blow away the dust from inside the scanner. Use the cotton wool buds to clean all the mirrors and lenses. Blow again to remove any fluff left behind by the cotton wool buds. It’s now ready for reassembling.
When you fit the scanner back into the printer, make sure it’s seated correctly. It hooks in at the top first and there are two locating lugs on the right hand side, one at the top and one at the bottom.
Be careful not to pull the two flat cables out of the scanner. When you fit the plate and logic boards back into the printer, be careful not to trap the purple wires from the top of the scanner behind the metal plate.
It’s probably best to leave the side covers and back cover off until you’re sure it’s working. Power the printer on. If you get any error messages, check all the cables are connected. Any scanner related errors are usually caused by the flat cables from the scanner coming out or the purple wires from the scanner trapped behind the metal plate.
Do a test print. It should be looking good now. If the color alignment isn’t spot on, run the calibration routine which is desribed in this post:
HP Color LaserJet 2605 – Colours Out Of Alignment
One final note. I once had one of these printers where someone had attempted to clean the outside of the lense from inside of the printer. Whatever they had used to clean it with had scratched the surface leaving it opaque instead of transparent. This required replacing the whole laser / scanner assembly to cure it.
If your Hewlett Packard Color LaserJet 2500 Attention light flashes after every page and you have to press the Go button to continue, you need to check the size of the paper in the paper tray and the size of the paper set in the printer properties.
If these are the same, print out a config page by pressing the Go and Cancel buttons together. Look for the Default Paper Size in the bottom right of the first page.
What you might find is that the paper in the paper tray is A4 and the software is set for A4, but the printer has defaulted to Letter size.
In normal use, this won’t happen or you probably won’t notice it. You’re more likely to come across this in a workshop enviroment while repairing and testing the printer. You will see it when you print a test page or config page.
Two possible causes of this are:
- You’ve replaced the formatter board and the paper size is set to the factory default Letter.
- You’ve performed an NVRAM INIT on the printer which has set the paper size to the factory default Letter.
There’s two ways to fix this. If you’ve got the original CD that’s shipped with the printer, there’s a utility on it to set the default paper size.
If you’ve not got this CD, you need to send a file to the printer to set the default paper size. This is the contents of the file with comments to explain what each line does:
←%-12345X@PJL Start PJL job
@PJL SET SERVICEMODE=HPBOISEID Enter Service mode
@PJL SET CRPAPER=A4 Set cold reset page size [=Letter/A4]
@PJL SET SERVICEMODE=EXIT Exit Service mode
@PJL RESET Perform PJL Reset
←%-12345X Exit PJL mode
The left arrow ← at the start of the first and last lines represents the Escape character. If you create this file using MS-DOS Edit, you enter the Escape character by holding down CTRL-P and pressing Esc. This will look like a left facing arrow, ←, on the screen.
There’s a good chance you’re not running a Windows 98 / MS-DOS machine with MS-DOS Edit. Whatever operating system you’re using, you will need to create a plain text file. You will also have to consult the documentation for the editor you’re using to see how to insert the Escape character.
Once you’ve created the text file, save it with any name you like but give it the pjl extension, e.g. A4.PJL. You then send this file to the printer. If you can go to an MS-DOS command line, the following will work if you are connected to the parallel port of the printer:
type a4.pjl > prn
The green light will flash for a few seconds and then the printer should go into the ready state. Print out a config page and check that the default paper size is now set to A4.
For your convenience, I’ve created A4.PJL for you which you can download by right-clicking and selecting save on the following link:
A4.PJL
The escape characters will look like squares if you open this file in Windows XP Notepad.
The symptons of this fault is that the colours appear to be out of alignment. If you look closely at a printout, you will see it is actually the black that is shifted horizontally and the other colours are ok.
You will also find that running the calibration routine in the menu makes no difference.
Just in case you don’t know how to perform the calibration, this is how it’s done:
- Press the green button with the tick on it (select)
- Press the right arrow button, System Setup shows on the display, press select
- Press right twice to show Print quality and press select
- The display will now show Calibrate Color, press select
- Calibrate Color Now will be on the display, press select
- You will now see Press √ to calibrate now, press select
- The display will briefly show Printing Document and change to Calibrating
- After a few minutes, the printer will return to Ready
You can try calibrating the printer and see if it cures the fault. If it doesn’t, the fix is to perform the Super NVRAM Initiializer.
Super NVRAM initializer
CAUTION Super NVRAM initialization will erase all network settings. Before performing Super NVRAM initialization, print a Configuration page, which contains network setting information.
When a super NVRAM init is performed, the printer enters the Generic Product Mode, which changes the language and country/region settings to “undefined.”
NOTE Super NVRAM init will erase all data stored in the protected NVRAM settings
Before performing the Super NVRAM Initializer, you will need to print out the config page, network config, and service page. You will need to print these out again after and change any settings that have been reset. The two times I’ve had to do this, I’ve been lucky and the settings have been ok.
Config Page
- Press select
- Display shows Reports, press select
- Press the right button twice
- Display shows Config Report, press select
Network Config
- Press select, on Reports, press select
- Press right four times, on Network Report, press select
Service Page
- Press select, on Reports, press select
- Press the left button, on Service Page, press select
Now you’ve printed out your settings, you can do the Super NVRAM Initializer:
- Turn printer off
- Hold down left and right arrow keys
- Turn printer on
- When you see the message Permanent storage init, release the (Left arrow) and (Right arrow) buttons
You will then be asked to select the language and location (country). When you’ve done that, the following message shows on the display:
TURN OFF
TURN OFF
You won’t have to turn the printer off and on. If you wait a few seconds, it resets itself.
When the printer is “READY”, print out another test page. You should find that the black is now aligned properly but the image might look blurred because the red is not aligned. Simply run the calibration procedure described earlier and everything should now be ok.
Don’t forget to reset any settings, especially the network settings.
If you turn your Oki C5300 printer on and get the following error message on the control panel display:
SERVICE CALL
020:FATAL ERROR
The firmware DIMM is faulty. This is quite a common fault with this printer and is easy to repair.
Grab the handle on the front of the printer and open the paper feed assembly. Open the lid. Remove the one screw on the top of the right hand side cover and remove the cover.
Facing the right side of the printer, about half way along and near the bottom of the pinter, you will see the firmware DIMM sticking out of the metal shield. This is the part you need to replace.
Just release the clips either side of the Dimm and it will pop out.
One thing you need to know is that there are two versions of logic board and each uses a different DIMM. If you look through the holes in the metal shield, somewhere on the board you will see SPA or OWL printed on the board. These are the names of the two versions.
It’s not too important what version of main logic board you have in your printer because the part numbers are printed on the DIMM. You will see two sets of eight digit numbers. The part number for the firmware DIMM you require is the eight digit number that is inside brackets.
For your convenience, here are the part numbers for the two different firmware DIMMS:
ROM DIMM for SPA PWB 42010613
ROM DIMM for OWL PWB 42010602
If you get a grinding and knocking noise from a HP LaserJet 4250 or 4350, the problem is the swing plate assembly and / or fuser. The swing plate assembly is a metal bracket with two plastic gears on it and drives the fuser.
The problem is that the teeth on one or both of the gears wear. You might also find that the plastic clip that holds the fuser in place cracks. The new swing plate assembly is modified to reduce the wear on the gears. It is also supplied with a modified two part spring loaded fuser gear. The new fusers are also modified with a metal insert inside one of the plastic clips to stop it from breaking.
The good news is that HP will send an engineer out to repair it free of charge even if it is out of warranty. Tell them it is making a grinding noise from the back of the printer and that you have tried reseating the fuser. If they tell you the printer is out of warranty, remind them that there is a service note that covers this fault.
Update
As of January 1st 2010, HP are no longer repairing this fault free of charge so you will have to do it yourself or take your printer to someone who can do it.
If you decide to repair the printer yourself, there’s a right and wrong way to do it.
The one gear can be changed very quickly by removing the formatter cover, formatter assembly, rear door, and fuser. Behind the formatter, you will find a black screw. After removing this screw, the gear can be removed from the back of the printer.
The problem with doing it this way is the printer will still be noisy if the other gear that you can’t see is worn.
The best, and correct, way to do it is to replace the whole swing plate assembly which requires removing the power supply board and is quite a lengthy process.
Briefly, what you have to do is; remove the top cover, both side covers, rear door, and fuser. Disconnect the cables from the power supply board at the dc controller. Remove six screws and an earthing screw holding the power supply board in. Remove the power supply board from the back of the printer.
The swing plate assembly can then removed from inside the printer by removing the three black screws. These are hard to get to and can be tight and are easy to round off. The swing plate is also tricky to get in and out of the printer.
If you get a genuine HP part, it should already have some grease on it. If you get a cheap compatable part, you might need to grease it yourself.
When you tighten the screws holding the power supply in place, pull upwards on the power supply. This moves the fuser gear closer to the swing plate gear.
Fit the new fuser gear supplied in the kit onto the fuser. Don’t forget to check the plastic retaining clips on the fuser. If they are broken, the fuser will need to be replaced.
Hopefully, your printer should now work, and should be a lot quieter.
