Question about Canon PIXMA MP830 All-In-One InkJet Printer
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.

Have you tried using a recommended cleaning solution and servicing your printhead as well as the cartridge itself. I refill my own cartridges and always clean the heads and cartridge before filling and replacing. I have done so on this brand and type of printer with no problems.

I could see some small smudges and I just gave my cartridges a quick wipe over the computer chips and that fixed it.
That saved me a 3 hour round trip and $100 or more dollars in costs. I rang Canon who directed me on to some (far-away) dealers and no one could even tell me what the error meant - let alone how to fix it.

I have an i4000 with the dreaded 6502 error. It happened after it chewed up a sheet of paper. I think the position of the printerhead was messed up, there was a rattling sound while the printhead was stuck in the paper. I switched the printer off. Then moved the head by hand all the way to the left, where it made a sharp 'click'. Then switched it back on. The head moved all the way to the right, another sharp 'click' and all was fine after that.

My printer is a Canon MG6150, I had the same error after unplugged the power because a kid was playing with the printer. I took all the cartridges out and put them back. Turn off the printer properly, unplugged the power for 5 sec, plugged back the power and turn on the printer. It works.

Pls do the following :-
Error code 6502 The Error code 6502 can occur in the printer as a result of ink tubes caught under housing and jammed the print head against the right hand side of the printer.

Thank you for your inquiry, Elizabeth!
I see that your Frigidaire dishwasher is displaying an error code of "UL" and you would like to know what it means. A "UL" error code means that your dishwasher is in relay test mode. You should be able to clear out the error code by pressing cancel and holding down the hi-temp button. If that does not clear out your error code I would suggest performing a reset on your dishwasher and you can do that by flipping the household circuit breaker off for at least ten minutes. Hopefully this information is helpful. -Matt
