---------------------------------;

E020-0081 is indicated at power on during initial rotation

When the window of the light-emitting/receiving segment of the patch image read sensor (FH7-7629-000 [PS23]) becomes solid with stray toner, the machine will not be able to accurately measure the density of the patch image off the drum.


To avoid the problem, the machine checks the patch image read sensor for soiling. While initial multiple rotation is under way, the machine measures the light from the surface of the drum without depositing any toner on it (drum background measurement); it will assume that the window is soiled if the measurement is lower than a specified level (COPIER>DISPLAY>DENS>P-SENS-P> optimum range: 400~600), thus indicating an error code (E020-0081) and stopping its operation.

First clean the Image Patch Sensor PS23 and reseat connector J2086, if the problem persists replace PS23 or the Drum to resolve the error code.


ALSO
This issue can occur if the Intermediate Transfer Belt Assembly Tension Arms are damaged, preventing proper tension from being placed on the Intermediate Transfer Belt.
