Question about Canon PIXMA MX850 Multifunction Printer

1 Answer

Canon MX850 Original problem was error 6A00 which I resolved from on line help by cleaning the track the print head travels on. In doing so, I released the print head lock lever and removed the 5 ink tanks. Now the lock lever has been secured and the tanks replaced. However the printer says that the two far right ink tanks (magenta and Cyan) are not in position. Their lights are flashing with the printer open. They are clipped into place as they normally are. What do I do? I realized after the fact, the book say not to touch the print head lock lever.

Sometimes releasing this lock leaver causes the far side of the print head mechanism to sit out, moving the contacts ever so slightly. Release the leaver again, using a bright torch make sure the cradles are sitting correctly and the circuit board that has the contacts for the cartridges on it has not moved. this leaver holds the entire assembly together and if it is not positioned correctly, it wont work correctly!!

Canon mx850 Error code 6A00


Hello thank you for using FixYa.

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 technology,I usually find the code almost 90% of the time it 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 etc.
I have found all those things in a purge unit.The offending item needs to be removed or the purge unit needs replacement.A
Canon Pixma MX850 Printer would still be under Canon warranty, get it into a shop and save yourself the hassel.
Incidentally, the 6A00 error pertains to all Canon printers made in the last several years, its not just used in one model & its always a paper path error or purge unit
I forget myself so here goes, the purge unit,called a spittoon assembly,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 will 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

Hi, (MX850) My blue ink has stopped printing. I




Performing Maintenance:




Note :
Be sure to install the ink tanks in the correct order indicated by the label on the Print Head Holder. The machine will not print if an ink tank is installed in the incorrect position.
Step 1
Printing the Nozzle Check Pattern.




If lines are missing or if white streaks appear


Step 2
Print Head Cleaning.

If the problem is not resolved after performing Print Head Cleaning twice


After cleaning the Print Head, print and examine the nozzle check pattern (Step 1) again.


Step 3
Print Head Deep Cleaning.



If Print Head Deep Cleaning does not resolve the problem, turn off the machine and perform another Print Head Deep Cleaning after 24 hours. If the problem is still not resolved and if you are sure that the ink didn't run out, then the Print Head may be damaged. Contact your Canon service representative.

Hope this helps.
All the best.

What to do about error 6A00 - no dealer within 2 hours! Thanks!



Hi there

Error A600
Your A600 is a paper path error, usually related to the purge unit. Try checking the purge unit for paper stuck in it.

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.
Almost 90% of the time is related to the purge unit being jammed with something and not being able to move.

Look for paper, paper clips, push pins, screws flower bud pods or the like.

The offending item needs to be removed or the purge unit needs replacement.

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 an electrical pump to milk the print heads and test for ink flow.


The purge unit is a white plastic assembly (on the right side of the printer where the print head homes) that is spring loaded on rides on a rail.
You can try moving it back and forth about 5 times or so and clean the rail with a cleanex and putting a little bit of some light oil on it and then close everything up and try it.

If you found this useful all I ask is call back and just gave a vote, it will gave me some satisfaction to know am helping some one, so I will keep on helping.

Error code 6A00 comes up. Data line and power cord


That error means the purge assembly is not working properly. Could be a scrap of paper stopping it from cycling properly. The purge unit is the cleaning assembly where the printhead parks, it has caps that draw ink from the printhead to clean and a squeegee to wipe off the excess ink. If the printhead comes to the center, unplug printer and check on the right. If nothing there you probably need a shop repair.
