E020-00A3 i have a clc 1180 machine gives error code E020 sub code 00A3. i changed the black sensor ,black developer saaymbly,drum ,and finaly the DC controll board....an still have the same error.. can you help me pls... best regards..

Code error E 020, 0173

Hi,

first check this site for the error codes.
clik here

The error code E020 refers to a density problem with one of the Drum Units.

ur hopper motor has jammed and it is not allowing the toner to go to the developer just open the hopper motor and put it into the developer or remove the connecter attacted to the developer. it will work . there is a gear actually on the motor which breaks.

So the only sol. is to replace, if it is under warranty caontact the customer care..
Goodluck,
Dont forget to rate me as fixya..

You need to Reset Code From Function_Clear_Err_OK. Check Dens_K in Display_Dens if it is to less i.e. bellow -2.5 Check Whether Black toner is present in hopper or replace Black developer

Most Probably Your Black Color Developing asssembly is overloded with excess black toner and might not be rotating. Check it

Hello,
The probable causes for error :

The developer has deteriorated.
• The developing cylinder fails to
rotate.
• The developing assembly is not
locked.
• The toner concentration (patch
detection) sensor is faulty.
• The developer inside the
developing assembly is faulty.
• The toner level sensor is faulty.
• The concentration sensor is
subjected to stray light (no cover,
front cover open).
• The photosensitive drum has
deteriorated.

In error code E020-0481, means that the problem is in black developer. So I would first try to replace Bk developer, check the developer station for malfunctions ( broken gears, broken developing roller bushings,... ).

Hope that helps!

toner clogging between sub hopper and developing assembly

black toner drum

Error :
Intermittent E020 / E061 codes.

Workaround :
It's possible that there is a poor drum ground from the static eliminator brush. You may need to replace the static brush with the drum grounding leaf spring from a CLC 350 (part numberFA5-9308-000). Follow the procedure in technical publication CTP.NO 700/800-69.
Error :
E020 sub code 0440 and light density on all colors

Workaround :
Check the developer assembly movement, i.e. up & down and that the magnetic roller is turning. Check the EPC readings, laser output, fold back mirror, and the connectors for the developer and the developer bias contacts. If all the above checks are good, then the problem can be with the AC voltage output of the developer bias HVT. The DC-voltage for the developer bias is split between two colors ( magenta & yellow ) or ( cyan & black ). The AC voltage is supplied for all four colors and it's loss will be seen in all the colors whereas the loss of the DC voltage would affect only two colors. To fix the problem replace the developer bias HVT part # FG5-3068-060.

ok so this is a code for the atr sensor.. you said you changed it is that the one right above the black dev that has the connector that plugs up under the control panel. if it wasnt take that one out and clean it... you can also check under serv mode copier display dens and see what iy says under window for each color they should be around 100 you may want to try to clear R-CON but then you need to put all adjs back to door specs

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
