The printer does not print or copy. The inkjet tray mechanism does not appear to move or sounds that it is stuck. The warning light is flashing. There is plenty of ink. This happened after trying to change inkjet, leaving the door/flap open for long period of time.

My alarm light and copy light are flashing and the display says error code 6A00 I have tried turning the machine and computer off and then rebooting , but it didn't solve the problem


I had this error (6A00) on a MP760 after a couple of months of not using it.

I switched it off, opened the lid and manually slid the cartridge-tray to the left.

Then I used a piece of tissue to clean the base-pad where the heads are stored. It turned out to be stuck in a kind of upward position and somehow the mechanism that moves the tray is released so nothing happens when you switch on the printer.

Touching it snapped it loose. Remove all ink residue, move the tray back to its most right position and close everything.

In case of a problem or clarification or my solution was insufficient, don't hesitate to post me a reply.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

You need to do some cleaning on this printer, because that causes it not to work , you can take the parts off from the printer and use alcohol to clean the dirty parts of the printer..

Hope that helps.............

Two red lights flashing on & off


This error means that some mechanical parts of your printer is in trouble. This could be some of the causes:

1. The print head is stuck somewhere or is unable to move because of some blockage in the printer's bay.
2. If you are using a Continuous Ink System, then the tubes might have blocked the print heads from moving.

To resolve, turn OFF your printer. Remove such blockage then turn the printer back ON.

Last page stuck in printer. I manually pulled the paper free. Printer will not print. Lower two lights blink in phase. Unplugged and replugged. Still same light pattern and no print. inspected inside and...


First open rear cover and 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 carriage lift mechanism for correctly moving. If this not help your printer need service.

Canon MP830 error code 6A00


HI,

Please the pixma off and open the lid.Now manually slide the cartridge-tray to the left.

Use a piece of tissue to clean the base-pad where the heads are stored.See if it is stuck in a kind of upward position and look if the mechanism that moves the tray is released if not then touch it and it will be loose. Remove all ink residue, move the tray back to its most right position and close everything.

Let me know if you still get the same error.

Won't print - just flashes it's lights at me!


I tried what phrek said (" Pressing the flashing buttons simultaneously, evokes the printer to spit out an internal diagnostic page ..."), but after the diagnostic page printed out the printer worked fine again.

Thanks for the help, and hopefully things work out for the rest of you as well.
