    I was scanning two documents for copying --using the auto document feeder-- and it choked on them. Now the alarm light blinks, and a message says 'check document.' I can still use it for printing, but not faxing, copying, or scanning.

    I need help. I have the same problem and can not find any information on the internet to help me get the "check document" alarm to stop flashing on the lcd screen. My canon will print but will not fax, scan, or copy now.

Finally fixed it myself. I ended up having to take the auto document feeder apart with a screwdriver and put this tiny plastic piece back onto its little cradle thingy. Working great now!

Green light and orange light keep blinking on and off


With the alarm light blinking, that could mean different errors depending on how many times the lamo blinks. Please refer to the link below for a canon document. Hope this could help.

Alarm light flashes; lcd toner low. But it's not!


How do you know toner is not low? You can't get rid of the message. The toner sensor is within the printer, and if it says 'toner is low', then it either "is" or the sensor is defective.

Canon super G3 that use 1TU-TV34 standard 33.6Kbps modems


Normal 0 Driver could be corrupt.
Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came with the printer. When the software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud
