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.
Solution 4a (Thanks to Vis8):
  • Lift the bottom part of the door (open)
  • When the cartridge carriage comes to the center, remove all cartridges
  • turn off the power
  • Turn on the power
  • After the printer initialized, the cartridge carriage will come to the center again
  • Replace the cartridges
  • Close door

Solution 5:
  • Sometimes a waste ink pad reset solves the problem

    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
    It's shit!...It never works properly...Always malfunctions.
    Get you a Brother, Lexmark or
    Epson...they work and are cheaper too.

    I don't know which metod work. But the last combination I tried was 6 times the Reset button. and now my printer is working again. (I put the cartridges out and in again, but didn't unplug in between. Only unplugged before the button combination)

    So.. if 4 times doesn't work try 6.

    My problem, besides the error code, is that I can't access the ink cartridges to remove them! I tried turning off, unplugging, turning back on . . . but nothing brings the ink cartridges within reach.

    Hey, found it in a youtube video... doing a ciss installation there might be too much light if the printer is 'forced' oped. Close it and try again. Helped me with my ciss and the MG5650.

    I'm having the same problem with multiple unsuccessful attempts of above solutions and new color cartridge.

    Method #4 worked. Try this first.
    1. Lift the bottom part of the door (open)
    2. When the cartridge carriage comes to the center, remove all cartridges
    3. turn off power
    4. Turn on power
    5. After the printer initialized, the cartridge carriage will come to the center again
    6. Replace all cartridges
    7. close door

    You will be OK

    I'm getting this error as well, but can't fix it because after taking the printer apart have found that a white plastic piece inside the printer is broken. I don't know how this happened, but the outer door wouldn't shut yesterday. If this happens to you, don't waste your time, as the paper won't feed with broken pieces.

    I got error 6502 when testing a printer with casing removed. Finally I found that cartridge lights were not properly recognized by optical sensor due to external light. Error was removed by applying darkness during cartridge recognition.
    Of course thats no "normal" situation but it demonstrates that cartridge lights are detected, probably as a check for genuineness. So possible reasons for error 6502 may be broken cartridge lights, bad contacts at cartridge, obstacles at optical sensor and bad quality replica cartridges.

    Re March 28/16 - "external light". Fixed my problem as well by just putting the cover back on after clearing the paper jam. :)

    Mines an MP640 running with a CISS. Problem resolved by removing the cartridge set and cleaning the contacts with Electrical Solvent Cleaner (available front hi-street electrical store). Be sure to wipe over with lint free cloth or kitchen paper towel. Before removing the ink cartridges remember first to close off the ink reservoir tanks. Bulldog clip good for this purpose.

    Cannon MX922 has no resume button. Tried all methods twice and I'm going to bed now and trying again tomorrow, the day after I'm going to buy a new printer like a Epson or Lexmark.

    Error 5100 on Canon printers

     MAJ 17/09/14

    Error 5100 appears on these Canon printers: MP140, MP150, MP160, MP190, MP210, MP220,  MP800, MP810, MP170, MP180, MP450, MP460, MP830, MP970, MP980, MP240, MP250, MP260, MP270, MP480, MP500, MP510, MP520, MP530, MP540, MP620, MP550, MP560, MP610, MP630, MP800, MP810, MP830, MP970, MP980, MG2100, MG3100, MG4100, MG5100, MP640, MP990, MG5200, MG5300, MG6100, MG6200, MG8100, MG8200

    It's a Carriage error.

    Solution 1:
    Look inside for a tiny object like a piece of paper, a staple...
    Solution 2:
    The purge cap (the white sliding mechanism that the print head parks to when it's not in use) may be not lubricated well enough . Lubricate the sliders with some white grease (don't get it on the small wipers or the black caps); this repair probably require to remove the right panel off of the printer to gain access to the purge mechanism.
    Solution 3: Clean the timing strip: there is a thin plastic strip running across the width in front of and below the drive belt: there are f…
