Error Message 6A00 ??
Hello there here is the codes
The 6A00 is a Canon generic code for paper path jam.
Move the printhead carriage back and forth a few times.
Check the purge unit: 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.
Press the ink pads down in the purge unit.
Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.
