Question about Canon MX700 Office All-In-One InkJet Printer

3 Answers

Error 6502 every time I load a new ink tank I get the dreaded error code 6502. In the past the code finally after many attempts of turning the machine off and on the problem went away....but not this time. I know the thing still works because it was working fine until I changed the tank and I KNOW I installed the tank correctly

    Not only do I have the problem, but when I took the unit to a repair center they told me they could not get the unit to fail. They claim they printed a bunch of pages, and it was fine. I picked up the printer, bring it home, and SAME ERROR.

    The solution here suggests pressing a "RESUME" button. My MX700 does not appear to have one... ???

    None of the reset ideas work for error 6502, and yes there is no resume button. It just goes away over time.

We just had the 6502 error after replacing 2 of the 4 ink cartridges. We had removed the cartridges to take to the store. When we replaced with the 2 new ones, everything was lit-up fine, but we kept getting the 6502 error. We tried unplugging, hitting the reset/stop (which just beeped at us - never did anything...) and different combinations of removing/installing all the ink cartridges AND the print head. Nothing worked. We eventually left the cartridges in-place and unplugged the unit for the night.

The next morning, plugged it in and it STILL had the 6502. But then turned if off again, waited an hour or so and when it came up after that, it gave an error that the 2 ink cartridges we didn't replace were not recognized. We opened the top and those two cartridge lights were blinking. We re-sat them and all is now good (knock on wood!)

We're thinking that taking the cartridges out to get replaced (they were out for about 1 1/2 hours) may have led to some ink residue drying in the unit....???? But when we have to replace any cartridges in the future, we plan on buying it FIRST and THEN swapping it out immediately with the empty one.

Good luck!

I turned off my printer. Then I lifted the lid, then the cover so you can get to the ink. Turn on the printer, while both are open and wait til you get the " Cover is open" on the display screen. The ink cartridge will stop in the middle with all light lit. Then shut the cover and wait til it resets.

Canon mp830 error code 6502

Hi Dee,
The error code 6502 indicates an ink tank position sensor error.There's no communication between the printer and the newly installed cartridges.To clear this,you have to remove the cartridges,check the plastic tape usually around them when new and make sure you COMPLETELY remove this tape.Ensure nothing is covering the chip or LED on the rear of the print cartridge.Also gently wipe out any appearing smudges.

Hope this helps.Thanks!

I have a Canon MP510 printer and have changed the print cartridges many times for refills but am now always getting error 6502. I've tried turning it on and off, unplugging it, holding down power button...

you mentioned that you turn off and on these is on of the solution of your problem
but in your case it doesn't work

error 6502 arise when ink tanks not snapped properly
follow the steps below
  1. Confirm that the printer is powered on and pull open the paper output tray .
  2. Lift the scanning unit (printer cover) completely. (The print head will move to the replacement position.)

    b. Do not touch any metal parts.
  4. Press on the pushmark.gif mark on the ink tank until the ink tank snaps firmly into place.
Make sure that the ink tank is inserted in the slot that corresponds to the ink tank's color.
5.Ensure that all the ink tanks are installed properly and the ink tank lamps light red.
1 -tank installed properly
2-not installed properly

6. check the status of each ink tank according to the way its lamp flashes.

  • - On: The printer is ready to print.
  • - Slow flashing (at about three second interval): Ink is low. Prepare a new ink tank.
  • - Fast flashing (at about one second interval): Ink tank is empty, or the printer is not ready due to an error.
  • - Off: An error has occurred and the printer is not ready to print.

  1. Close the inner cover and the scanning unit (printer cover).

    1. When closing the scanning unit (printer cover), be careful not to jam your finger.
    2. When starting printing next time, the print head cleaning launches automatically.

Error code 6502

That error says it's a ink tank position error, make sure there are no paper scraps in the paper path, and you might clean the encoder strip with a q-tip and water. Make sure the carriage can move freely from one side to the other.

Canon MP630 error code 6502

Error 6502 is the ink tank position sensor error. Basically means the printer can't see the inks. Try reseating them. If this fails you need to send it back.

Canon Pixma IP600D - error code 6502

Sometimes the Canon printers which use PG-5BK/CL-8 colour cartridges with chips will give error massages like 6502 or other types of error message to do with the cartridges, which has the orange light flashing and the printer will not work. Follow this procedure which quite often resets the printer and allows it to resume printing.

When error is indicated, turn power switch off so green light is extinguished.

First hold down resume button and then 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. Then let power button go.

Then 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. This normally solves the error problem - if not go through same procedure again.

Incidentally, you may find that if the chips had previously been disabled, the low ink warnings are showing again and they will have to be disabled once more. This would indicate that the above procedure clears the firmware memory of the disabling of the chips, this may be useful if you need some warranty work done on your
printer after the chips had been disabled.

Canon Pixma IP600D - error code 6502


What is the brand name and model of your printer? Make sure that your ink cartridges are precisely the correct cartridges for the brand and model that you are using. From what I have experienced ... if you try to use a used ink cartridge you will recieve an error.

Error 6502

Have you replaced the ink cartridge recently? Service error 6502 is an ink tank position sensor error. Service error 6502 generally means that your ink cartridge chips cannot be recognised. The primary cause of this is the blockage of the LED. Ensure that no tape, glue etc is covering the chip or LED on the rear of the cartridge. Problem more prevalent on third party replacement cartridges or ink systems.
