This Printer is hard to explain & service if u have never worked on it before--
u will need to access SERVICE MODE Level 1-and Level 2 for checks many things can go wrong in there without some experience on model

This process of removal & inspection of units can not be fully explained here-----
if no tech available----u should get a MANUAL to study product

This code could easily reflect that u need a developer change for BLACK



below is for REFERENCE PURPOSE ONLY----do not attempt if not trained/ have a tech read and perform
E020-0485
Check to see if the image patch sensor is reading the patches on the drum. In service mode <Level 2>DISPLAY>DENS>, check P-SENS-P and P-SENS-S for values. If the values are zero, replace the image patch sensor or check that the patch sensor shutter mechanism is working correctly.



How to read the image patch sensor-
The way to check the 3 LED sensors on the image patch sensor----
Enter service mode Level 1, go to <DISPLAY>DENS> , go to second screen and it will display <PCH-LED-1>(front), <PCH-LED-2>(center), <PCH-LED-3>(rear). If any read zero, replace the image patch sensor (FM2-2494-000).

E020 (ATR error) detail

xx85 Patch image sampling (center) error 1
E020-xx85 Difference between the patch measurement and the dark current measurement is 30 or less in patch detection

DISPLAY>DENS>DENS-S-Y/M/C/K (patch image measurement value) - DISPLAY>DENS>D-CRNT-P (dark current measurement
value) </= 30

1. After cleaning the Patch Sensor,
execute FUNCTION>MISC-P>PT-LPADJ.
Select DISPLAY>DENS>PCH-LED2, and check the value of PCH-LED2 (1).

2. After removing the Patch Sensor Shutter,
execute FUNCTION>MISC-P>PT-LPADJ.
Select DISPLAY>DENS>PCH-LED2, and check the value of PCH-LED2 (2).

3. If (1) is more than 240 and (2) is between 80 and 240, replace the shutter and solenoid. Then,
execute PT-LPADJ again. If the value is between 80 and 240, complete the remedy. If not, go to step 4.

4. After replacing the Patch Sensor, execute PT-LPADJ. If the value is between 80 and 240, complete the
remedy.
