Title : E020 with Multiple Sub Codes for all Colors
Problem : E020 with Multiple
Sub Codes for all Colors
Solution : Check for a pinched or
damaged wire harness from PS3 Patch sensor #2 from connector J426 back to the
Side Driver p.c.b at connector J3415 and at PS7 ATR sensor from connector J209
back to the Rear Driver p.c.b. connector J3802.

E020 - The toner is not adding correctly into the developing assembly. 1) If toner hopper is overfull, the toner motor worm gear splits as a result of the hopper becoming packed tight. 2) If the hopper is 1/2 full or less, the worm gear splits under normal use.
1) Advise customer to add toner only when the toner light is lit, right away, and replace toner motor, or 2) Just replace toner motor (FH7-1762-030).
After verifying that the toner hopper is working properly, check that the web solenoid is activating. Clean the web solenoid and ensure free action. This has been known to clear an E020.
After verifying that all is well with the toner hopper unit, consider the DC controller. It has been noted that some DC controllers do not provide sufficient current to drive the hopper motor. Replace the DC controller COL97.08.25 M0000244.txt.
E020 indicates a Black Toner malfunction. If you've recently changed the toner and failed to distribute the toner by gently shaking it from side to side, this could be the cause of this error or if the toner is very low it could trigger the same error. 01B0 is a drum error related to your toner error message. If toner cartridge is good, remove the cartridge, clean the drum, replace the cartridge and both errors should clear. A dirty drum will also trigger your 1st error e020.
Did you change the Magenta stater/ developer? A E020 code is saying that the toner desity is low. Try replasing the developer and run the ATDC for Megenta and see if that helps. You may have a problem with the developing ass'y it self. You may be able to take another colors dev. ass'y with the hopper open and see if the code goes away. The sub code 0124 means that it is the Magenta dev. ass'y
This error has to do with Toner concentration of the Black ( 04 ) part of the sub code. The "00" has to do with the reference level or signal value for black. Look to see if the Black toner sensor is soiled. You have to swing out the toner hopper assembly to access the sensor. You will see two thin gray cables coming down from under the control panel. Since you have access to both assemblies - toner and paper jam detect - carefully remove both and clean with canned air. Be careful since you are so near to the $800 drum. Replace both and test. If you still have problems and the drum is old, several years, and has over 40,000 copies on it, you may have to have the drum changed and I recommend a tech do it. Good Luck.
