Canon PIXMA MP800 Error 6A00


The 6A00 is a Canon generic code for paper path jam. Some where in the paper path a sensor is activated indicating paper jam so the printer will give off a 6A00 code. As a Canon tech, I usually find the code, almost 90% of the time, is related to the purge unit being jammed with something and not being able to move. Moving the print head assembly will not clear a purge unit if its jammed with paper, paper clips, push pins, screws, cookie crisp, flower bud pods or the like. And yes I have found all those things in a purge unit. The offending item needs to be removed or the purge unit needs replacement. A Pixma MP830 would still be under Canon warranty, get it into a shop and save yourself the hassel.


Incidently, the 6A00 error pertains to all Canon printers made in the last several years, its not just used in one model. And its always a paper path error or purge unit.
I forget myself so here goes, the purge unit, called a spittoon assembly in an HP, lexmark, and other inkjet printers, is where the print head assembly parks when not in use, also its other job is to clean and make sure the print head is clean and open for printing. That is why you'll find the print head assembly parked on top of it. It also has a an electrical pump to milk the print heads and test for ink flow.

When I open the top cover of my Multifunction MP830 printer, the Carriage, Printhead, and ink carts no longer come to the center such that I can replace an empty ink cart". Of course there is some other error posted on the small display and with my Crystal Ball, I can see from here that it says, "Error 6A00".

This is the AP motor error from the Purge unit indicating that your purge unit did not complete a full cycle. As a result the purge unit still has the printhead and Carriage ASM locked in the far right "Park" position. Sooooo the only solution for you is to take the printer apart.

There is one "Despriate Trick" you can try, but it has less than a 1% chance of working. You may have to try this 5 times and see if you get lucky.

This entire process will have to be repeated, not just part of it, if your are going to get lucky.
1. Pull the power cord and allow internal memory to discharge and loose memory. This takes about 3-4 minutes
2. Plug the power back in
3. With the Cover open, press the main power button.
4. Count to 5 and pull the power cord out.
5. Wait 30 seconds.
6. Check to see if the printhead has moved ANY AMOUNT AWAY FROM THE PARKED POSITION, OR IF YOU CAN MOVE IT BY HAND WITH VERY LITTLE FORCE. This means you should not use any excessive force.
7. If it moved you are lucky as you are now able to move it to the far left of the printer such that you have access to the purge unit. With access you can try to see if you can un-jam the white plastic wiper blades, as this is 75% of the cause of all purge unit jams. Press the ink pads down gently and see if they are free to move down at least 1/4 to 1/2 inch. If you think you freed up anything, close the cover and re-plug the power and see what you get.
8. If all of item 6 & 7 failed, go back to step 1 and start over. Then when you get to step 4 change to wait to 8 seconds. The next time change it to 3 seconds. The next time change it to 10 seconds. The last time change it to 1 second. Now you can give up.

What you were trying to to was to catch the purge unit in its normal power on test cycle were it moved through all physical positions. In one of those positions it drops the locking tab on the printhead for just a second or more. If you were able to pull the power at that exact time, you would be able to move the printhead once the power is removed. While the power is on, the printhead carriage drive motor is active and will NEVER EVER LET THE PRINTHEAD MOVE WITH POWER ON.

Sometimes this works, sometimes it doesn't. Good luck

THIS really does work! Even though I could barely understand the directions, this fixed my problem with my MP830! Thank you! Here's what I did:
1) Turn off Printer
2) Open the printer
3) Move the ink to the left
4) Look in the space to the right where the cartridges usually stay and there is a little tray/lever that is covered in a small sponge (mine was covered in ink as well)
5) Poke/wiggle the sponge/tray until it pops into place (I barely had to touch mine)
6) Turn the printer back on, and voila!
This really worked for me, good luck!
