Troubleshooting for SC Errors

When SC285-02 (MUSIC Error) Is Displayed

Causes

• The ID sensor cannot detect the MUSIC pattern

• Color registration error is larger than the specified value

[Assumed Cause]

1. Large drifting

"Large drifting" is the state where the color registration error is larger than the specified value.

In the "Large drifting" state, the MUSIC pattern is shifted a long distance in the main scan direction

(side to side), and is moved to the position where the MUSIC Sensor (TM/ID sensor) cannot be

detected, or each pattern cannot be detected due to the pattern overlapping.

2. MUSIC pattern density error

Pattern with the lower density

3. Defective Image transfer belt/Image transfer unit

• Belt scratched

• Belt corrugation, belt skew

• Cleaning failure

• Background stains

• Filming

"Filming" is a phenomenon where surface properties change over time.

Glossiness is one of the surface properties. In the "Filming" state, the whole or part (belt

shaped) of the Image Transfer Belt surface becomes foggy. "Filming" changes reflected light,

and the MUSIC Sensor (TM/ID sensor) may detect the input wrongly, which causes an error.

4. MUSIC sensor (TM/ID sensor) defective

• Connector/ harness disconnected

• Sensor surface dirty

• Sensor malfunction

• BCU malfunction

5. Paper transfer contact/release mechanism defective

• Connector/ harness disconnected

• Motor/ sensor malfunction
