"E020" Black toner feed problem
the4050's were notorious for this problem.
open the hopper and vacuum out all the tone and locate th thin metal arm that rotates. I used to bend it inwards, so there would be a hump in the middle of the arm( so it does not touch the sides of the hopper. also check the auger that feeds the toner into the Devellopper to see if it is clogged. thirdly the motor for the hopper does go bad ( this is the one that turns the metal arm to mix the toner)

C2500 problem with keyocera mita 3035


A C2500 Code is as follows (direct from tech manual.)

Paper feed motor problem.

Poor contact in the paper feed motor connector terminals.
Defective paper feed motor rotation control circuit.
Defective drive transmission system.

Solutions:

Reinsert the connector. Also check for continuity within the connector cable. If none, remedy or replace the cable.
Replace the paper feed motor.
Check if the rollers and gears rotate smoothly. If not, grease the bushings and gears. Check for broken gears and replace
if any.

Most of the time it is the motor if you power the unit down and unplug it. Wait 30 seconds power it back up and it should (key word) bypass the broken cassette. To find out if it is the motor you can switch the motors with cassette 1 and 2 they are the same.

Hope this helps.

Canon NP4050 putting out blank pages


The NP 4050 has been known for given blank copies... Is the developing unit locked in place... There is a Grey or blue lever inside the front door to the right... It is under the toner hopper. It's been along time... I believe the lever should be clicked to the right and up. Also there is a locking screw that holds it in place, Most times that screw is missing and the unit falls away from the drum unit and you get blank copies and the front door will close.. Good Luck

What does E000020-0010 error code mean?


e0020 is to do with there not being enough toner in the developer unit.

Firstly it may be a good idea to check/change to toner cartridge.


Switch off and disconnect from mains for the next bit.....
If ok remove the developer roller, cover is above the manual tray on the right hand side then once inside dev unit has connectors at either side, check they are properly seated. If you need to remove the dev there are several black screws around a metal plate all need removing. The roller should be black with toner. May need replacing depending on age and usage of copier.

Code E020 on a NP 4050


How about this, Take the developing unit out and take the ATDC sensor out and plug the hole up in the developing unit. Reinstall the developing unit and cheat the front door switch and plug the sensor back in and hold it in your hand and make a copy. Dose it vibrate? If it dose not the sensor is bad... If you really get tired of working on the problem and you don't go to the copier to often and they are not billable, try this.... Take the top cover of the dev. unit and spoon toner into the dev. unit till it is almost full and reinstall it and clear the error code in service mode and just remember to add toner in to it every so often.
