6A80 is APP position error.First, make sure there is no paper jam anywhere in the machine.. look inside, rear, where the paper tray (output)
is, etc to see if you find any shreds or torn paper that may have gotten stuck and you didn't see.Look carefully in the zone of Purge unit, using flashlight in the right side on printer.Check the sheet feeder.If this not help your printer need service.

I’m happy to help further over the phone at https://www.6ya.com/expert/william_83fc156eee2b555e

It is not designed to do so but try this... Go into your FAX menu and select "Display Device Settings." From there, choose RX settings and then DRPD. DRPD is designed to allow you fax to only answer calls with a distintive ring pattern. By setting it to a pattern that doesn't exist, it should allow the calls to be ignored. Try setting it to something like short short long. Once thats done, go into "User Settings" and "RX Level" and set the volume to zero so you don't hear it ring. If that doesn't work about all you can do is keep the phone line unplugged until you need to send a fax.

It sounds very much like a failed printhead or printhead driver; the circuit that controls which jet is addressed or left blank.

I have a Canon Pixma MX700. I have printed many great photos but not it prints a faint image in the background but the rest of the photo is covered with black ink spots, what can I do to correct this problem?

1. Disconnect and reconnect the electrical cord to ensure a secure connection 2. Press the ON/OFF button to power on the multifunction device 3. Try a different electrical source / outlet
