Hi, I'mCustomer Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
To resolve the 6000 error, please follow the following steps:
1. Turn off the printer and disconnect the power cord and USB cable.
2. Remove paper from the automatic sheet feeder (in the back).
3. Gently pull jammed paper out, if any.
4. If the paper tears and a piece of that remains inside the printer, open the printer cover and remove the paper from inside the printer.
5. Check ASF with a bright light to check for obstructions. Remove any if found.
6. Open the rear cover to check if the paper is jammed.
7. Pull out the cassette and check if the paper is jammed inside the cassette area.
8. Load paper back into the ASF or cassette.
9. Reconnect the power cord, turn on the printer and confirm that the Alarm light is off. (If there was any jammed paper remaining in the printer, the paper may be automatically ejected.)
If the above procedure does not resolve the 6000 error, let me know
Has everything worked out, do you still need help please ?
Unfortunately, the persistence of the 6000 error after these steps leaves only the possibility of an internal hardware fault. Repairs at a canon service center would run you $150-250 but For $80-100 you can replace the entire printer with a brand new model, with current technology and a fresh warranty.
Hope this help
