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.
If you have a Dell 5100cn or 5110cn colour laser printer that is noisy when printing and prints faint black or no black at all, check the black developer and the developer drive assembly.
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.
