68.0 PERM STORE WRITE FAILED on a Hewlett Packard LaserJet 4100 can be repaired without replacing the formatter board. This error isn’t mentioned in the service handbook or on the HP website.
This error occurred on a long print run after 100-200 pages. The printer stopped mid print with the Attention light, Ready light, and Go lights all on indicating a service error.
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.
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 just a follow on from my previous post about updating the DC Controller firmware on the Hewlett Packard Color LaserJet 2600 to fix the ghosting fault. Once you’ve fixed your ghosting fault, you can update the main program firmware on the formatter board if you want to.
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.
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.
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.
