Re: error code e000021-0003

Start by the book:

The sensor does not detect the flag when the developing rotary stops at development point:

Rotate the developing rotary in a counterclockwise direction by hand to see whether it rotates smoothly

Inspect developers,ITB condition,developer motor,connectors......

[ Case in the field ]

Description

E021-0003 can be displayed when the rotary HP sensor cannot detect the developing position detecting sensor flag although the developing rotary stops at

development point.

Cause

In the field, this symptom occurred because of breakage of the developing position detecting sensor flag that is located on the rear rotary flange.

Field Remedy

Visually inspect the rear rotary flange to see whether or not the developing position detecting sensor flag is broken.
