Error Code 6502 on Canon printers


Error Code 6502 appears generally after changing a cartridge.


Solution 1:
  • Unplug the printer.
  • Remove the faulty Cartridge
  • Plug in the printer and press and hold power button
  • Keep it held down. Press Resume twice, and this should reset the fault.

Solution 2:
  • The last cartridge installed may be faulty.
  • Install a new cartridge

Solution 3:
  • When error is indicated, turn power switch off so green light is extinguished.
  • Hold down resume button and hold down power button so both are held down at same time
  • When green light comes on, continue holding down power button and let resume button go, then press resume button twice.
  • Let power button go.
  • Press resume button four times, power button should be released before doing this.
  • Wait until printer settles down, if power is off, turn on. If power will not come on, remove power cord from back of printer, then wait 15 seconds before plugging back in again and turn power on.

Solution 4 (thanks to Anniina for the tip !):
  • Unplug the power cord.
  • Remove all ink cartridges.
  • Plug cord back in and turn the printer on.
  • Replace all ink cartridges.

    Tried 10 times. Orange light is still flashing, printer will not work. Canon PG-5BK/CL-8 cartridge. Error mesaages 6502. I'm dead in the water. Never happened before. Have a stock of cartridges that I can't use.

    Hahahaha... solution 3 is like the "secret cheat code" to make the printer work. If only it did....

    None of these worked for me, but this is what did:

    1. Unplug the power cord.
    2. Remove all ink cartridges.
    3. Plug cord back in & turn printer on.
    4. Put all ink cartridges in.

    That worked on mine; I hope it does on yours.

    Hi guy, after several try, this is my conclusion:
    The printer head contact is dirty, try to clean it
    The "ink level detector" on each ink cartridge has problem to contact, try to clean it
    The "secrect cheat code" is offical for all Canon Pixma, it reset the printer "boot" process
    After all if still non-working, try some old-ink cartridges and see what happens, if possible (i didn't tested yet but i thinks it works), try to replace the "ink detector" on each cartridge

    I'm using CISS with cartridges with auto reset chip on my iP4700. The 6502 error occurred after I was removing the air gaps in the CISS tubing. "Solution 3" worked for me. At the end I had to power off the printer, unplug the power cord, wait 15-20 seconds, plug the power cord and printer powered on normally.

    There is only one solution to this problem.....NEVER EVER BUY A
    CANON PRINTER AGAIN!!!!!!
    It's shit!...It never works properly...Always malfunctions.
    Get you a Brother, Lexmark or
    Epson...they work and are cheaper too.
