Description: White Level Correction Error: Rear Side The automatic adjustment has failed to correct the white level (rear side) to the permissible range.
Causes: • CIS is defective. • MPU is defective. • Power/signal harness is defective. • Scanner unit condensation • CIS is not set properly, or is dirty. • The white plate is not set properly, or is dirty.
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. 1. Clean/reset the CIS and white plate. 2. Replace the units in the following order: • CIS • Engine board • PSU/Signal harness
Code: SC154-00
Description: Scanner Communication Error: Rear Side Cannot correctly establish communication with the MPU (SoC-AFE)
Causes: • Communication error with MPU (SoC-AFE) • PSU is defective.
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. 1. Clean/reset the connector. 2. Replace the units in the following order: • Engine board • PSU/Signal harness
