I have a Canon PC

Have you tried making copies with out the cartridge installed? It should jam due to paper not following proper path (will most likely ride high and not guide into fuser rollers) but, does it sound different? Does it also jam in the same fashion if feeding through the manual bypass? How many copies are on this cartridge? Please let me know progress...Tim

My research for your model has suggested that the service mode for the Canon PC 850 is used to reset error codes that prevent the machine from continuing. I have seen many instances of these instructions, do these appear to match the machine you are working with? "I entered service mode and it fixed itself. With the front panel open and the copier lid/carriage lifted up, I used a paperclip and stuck it in the small hole on the front grey panel (DC controller) and simultaneously used a pen to hold down the tab in the slot on the lower left edge that makes the copier think the lid is down. It reset the error code and all is OK now." But this is not what you want. I believe you want a diagnostic mode to give you an error code relating to a motor, not a reset to clear an error. I cannot give you this code, but I would suggest that if a motor were bad, your problem would be more consistent, and the first copy would not be fine. The fact that the cartridge gears move with difficulty is troubling. Here are some cartridge troubleshooting tips: Checking the toner cartridge Ensure the toner cartridge is correctly installed and rotated into its opened position. Remove the toner cartridge in question. Inspect the cartridge?s cap to ensure it is securely taped in place. Tilt the cartridge back and forth to ensure it contains toner. Rotate the gear at the rear of the cartridge. You should hear the auger coil move inside the toner cartridge. If the auger coil and gear rotate correctly, the cartridge is good. It seems to me that your auger coil and gear are not rotating correctly, therefore your cartridge is not good. I understand that you don't want to buy a new cartridge if that is not the solution, however I suggest that if it doesn't fix your problem the money is not wasted because eventually you will use the new cartridge once the machine is fixed. Buying a cartridge may prevent you from hiring a Canon service tech, but hiring a service tech will not prevent you from eventually buying another cartridge. Hope that helps.
