[EF13] Saddle unit paper holding home position detection error

Is there any mechanical problem when the paper holding cam is rotated?

 YES Fix the mechanism.

NO

Is there a disconnection of the connector, incorrect installation or breakage of the paper holding home position sensor (S38)?

l	YES •	Reconnect the connector securely if there is any disconnection.
l	•	Reinstall the sensor correctly if there is any incorrect installation.

• Replace the sensor if there is any breakage.

NO

Is the harness between the paper holding home position sensor (S38), paper holding clutch (CLT4) or saddle transport motor (M16) and the CN8 of the saddle control PC board (SDL) dis- connected or open circuited?

l YES • Reconnect the connector securely if there is any disconnection.

• Replace the harness if open circuited.

NO

Replace the saddle control PC board (SDL).

[CB94] Saddle transport motor (M16) abnormality

*The [CB94] error also occurs when the error [EAB0] or [EF13] has occurred consecu- tively for 3 times.

Is there any mechanical problem when the transport rollers are rotated?

 YES Fix the mechanism.

NO

Is the harness between the saddle transport motor (M16) and the CN18 of the saddle control PC board (SDL) disconnected or open circuited?

l YES • Reconnect the connector securely if there is any disconnection.

• Replace the harness if open circuited.

NO

1.Replace the saddle transport motor (M16).

2.Replace the saddle control PC board (SDL).
