Re: error e020

The developer unit is looking for toner from the hopper. E020 can also be the DC Controller or the developer unit itself. The toner cartridge is probably fine. This can be complicated to fix. The copier is probably still under warranty. It's better to call up Canon 1-800-828-4040 and have them send out a Certified Technician to fix this. Sorry I couldn't help more. Ray

Hi there
I have looked it up and what it says about it I have put down for you so you can gave it a try hope it works for you.
E020-01A9 Error Code.

For ATR control, the detected Toner/Density ratio exceeds the lower limit (3%) 3 times continuously for Yellow

The ATR Sensor and Patch Image Read Sensor both determine toner density. Depending on the density readings the copier will or will not add toner. Check the status of the Drum Unit under COPIER>DISPLAY>MISC>DRUM-LIFE. The Patch Image Read Sensor looks at a patch of toner that is generated on the drum for each colour and determines the amount of toner that is in the patch by the amount of reflected light. If the drum is not creating the patch correctly, the patch reading will be affected. Replace the Drum Unit if it is 80% of its rated life or higher. ..

your back up data is currupt, you need to change your p-sens-p value check your door spect for all default value. after that clean your sensors that is found below the black developing assy. take machine off unplug from outlet replug turn machine on DO A GRADUATION ADJUST that should solve the problem / if not unplug the the same sensors , then repeat the first prod.

Title : E020 Error Code Problem :
When you have followed all the steps from the troubleshooting guide in the Service Manual and still have not resolved the issue, here are some possible areas that might be related.

Solution :
1) Confirm that the toner and hopper sensors are being wiped completely.
2) Check the Gear Train on the hopper assy it may be locked up.
3) A possible bad hopper unit cable. FG5-5016-000. See The Parts Catalog page 620-2 item # 60.
