I'm not very far along with it and cannot promise a finish date due to the fact I have a job and family to take care of.įor those of you that say this is a poor design, it's actually excellent except for this clutch part. I did take pictures and whand-wrote instructions when disassembling it and am working on a guide. If your gear is cracked, it won't pop down (or pop back up if it's down when you start the print) Normally a roller will pop down and start pushing the paper.

The way to know for sure if your gear is cracked would be to try to print something, and watch the paper pickup area. Also you have to be careful not to super glue the gear to the metal roller as it does need to move a bit. If you can very carefully super glue it, it will continue working just fine. That white gear cracks as previously mentioned. The black cover will pop off and is impossible to get back on without disassembling the printer. The fake paper jam issue is a white gear underneath that black clutch cover on the left side. So if anyone know where I can buy this poorly made piece of plastic and the best way to replace it, please let me know. Hit OK to tell the printer I cleared the jam and watched with a flashlight(several times) The print carriage blocks the view some times as it goes by, but i can definitely see the split. Insert a small piece of plastic to fake the printer into thinking the cover was closed. The way I noticed was to open up the printer cover to view the print carriage. The white part of the clutch is suppose to be forced to the right, but mine is split so it just slides past the pin that is suppose to move it. If there is no paper movement a paper error is received. When this happens a gear is moved to the right and engages the paper feed. Upon further investigation inside the black clutch (inside left hand side of printer), there is a white piece that is suppose to move to the right and engage its black counterpart. It is making a clicking sound just before the error message appears like the tiny plastic gears are slipping. I do not believe it is a logic board issue. I also get the improper shutdown error, but I think that is because the ink carriage does not return to its proper position do to the paper jam and then the printer gets turned off.
I have receive the fake paper jam message. Then the paper jam error message is given. When the unit is turned on the carage will begin a "search rutine" but will eventually go all the way to the left side when the carrage is directly above the ink cartigages, make a strange clicking sound for a few seconds and then the carrage will move to the right about 4 inches and stop. However, using the units power button makes no difference. I've also noticed that the unit gives me an improper shutdown error as well and tells me to turn the unit on and off with the units power button and not a switch on the power switch. Is there some way to determine what might be causing this problem so I can repair the printer on my own? I've read about bad or stuck sensors in other threads having phantom paper jams. However, I've reviewed all the methods of looking for paper pieces and have found nothing. I have an HP Officejet Pro 8500 Wireless printer that keeps reporting a paper jam. I'm new to this forum, sorry if I've duplicated a thread I didn't find.
