Jun 19, 2008 - Hp officejet 7110 caterige chip rest code. Posted on Sep 15, 2009. In this case i dont think you need to service manual.
Due to the initial investment and the fact that most of these great printers are out of warranty, I would suspect that a number of us can and would like to fix problems that may come about with our printer. Has anybody found if there is a Service/Repair manual for the E809a? I have to guess some type of information was made available to warranty repair service centers.
All I've found so far are links to the User Guide or virus infections. If not, has anybody figured out the process of opening the case of the printer without breaking anything else? I'm interested in accessing the right hand side to re-synchronize the head cleaner and ink cartridge positions when in the parked position to correct a space conflict resulting in a paper jam indication.
Thanks for your interest and help. I've had the E809a for over 5 years. The printing head eventually becomes blocked with dried ink. It is not enough to just clean the head with luke warm water (explained in detail elsewhere), but you need to remove all ink accumulations, including in the part of the printer hidden by the cover. To remove the casing, you need a T-10 hex screwdriver. Remove the four screws visible when you lift the lid.
You will find a fifth if you gently bend the left side of the lid backwards; then you can easily remove the back and left side. Next you need to manipulate the right side at the back until the sixth screw becomes visible at the top just beside the right side hinge of the lid.
It will still require patience to remove the side (and even more when you put it back after cleaning, but it is possible). Then you the top lifts off and you have access to the interior.
Use Q-tips, moistened with water if necessary, being careful not to leave any lint, and remove all traces of dried ink. Put back together in the reverse order. Once reassembled, the printer operates as when new.
Good luck, Gavon.
