HP 3000/3600/3800/CP3505 Color Printer Mechanical Problems
These printers have a lot of plastic pieces that can break with just the opening and closing of the front door. Some that lock the cartridges in place, others that actuate the cartridge shutter (drum cover). When they do break they can cause errors, jams, and even print quality issues.
For the 10.92.XX cartridge not engaged error there are a few different plastic pieces within the printer that might cause this error when they break. There are locking levers for both the left and right sides of each print cartridge. The left side locks are just mechanical as they hold the cartridge in the correct position. RC1-6633-000 for the color cartridge and RC1-7618-000 for the upper or black cartridge. The removal of the left side cover and then the HVPS is required to replace these. The right side locks are mechanical as well but also have a grounding spring involved. RC1-6640-000 for the right side lock lever and RC1-6641-000 for the grounding spring. The right side lock levers require the removal of the cartridge drive assembly. This procedure is much more involved than just a cover and a board so pay close attention when removing. If no error is generated when these fail there will most likely be some sort of print quality problem such as light print, uneven densities, and hazing on the page as the cartridges are not held in the correct position for the printing and cleaning processes.
