[Error Code] E0020 Canon IR 3235

[LTTP]

We have a machine that throws this code E0020 whenever we try to either print or copy, so far ive tested bootle motor 5 on service mode-function-prtchk-motor 5 and it spins normally, after doing this the machine started printing and copying just fine.

However, trying to perform a test with function-install-toner-s always throws a NG message.

Developer assy actually has toner (from the motor 5 test i did maybe?), ive opened it up and cleaned the inside where the sensor is located, ive manually tried to open the hopper by pushing the small plastic tab and i could see toner falling down so theres nothing obstructing the way, also one time it gave an error E840 which is for the PSU fan failing, the i just turned it off and on again and it went away hasnt happened again since.

What else should i be testing to find the cause of this? i dont have another one here for a few days so i can swap the dev assy and see if that fixed the issue.

check for toner supply in hopper?? Check if there is a toner clog going into the developer unit next. If no clog then it is either the hopper toner sensor, developer unit sensor or the DC controller. More likely one of the sensors. (E020)

If toner is going into dev unit, can you check the sensor in dev unit next?

Did you change the sub hopper from a working machine ? (with the cable FM3-5076-000)
Rotate the toner bottle when you make "toner-S" can you see it?

Just swapped the sensor and hopper motor, not the cable tho.

Re: E0020 Canon IR 3235

One question... does the Dev Assy has any other sensor besides the one on the ffront where the cable is?

No only the toner sensor in the front.
stupid question but did you change the toner bottle with an new one.
I install a new machine last week and the "toner_S" give me NG, with an another Toner Cartdridge was it OK.

Something i havent noticed until yesterday thati had the time to work on this machine, is that the bottle has a broken claw, cant find the plastic piece tho but i just swapped the full dev assy just in case and cleaned the sub hopper, gonna try with a good bottle later today.

Any other suggestion? im completely BLANK.

That 32xx series turned out to be garbage. I think I've replaced the hopper on every 32xx at least once. I don't even hesitate anymore. Changing the hopper will probably take care of your problem
