Description: Scanner Home Position Error 2 The scanner home position sensor does not go ON. Details: Error detection timing • During homing • During an automatic adjustment • During a scan from the ADF or exposure glass. After an error occurs • Stop process, Operation panel display, LED indication, Logging • Scanner is not usable (Copier/Scanner/Document Server applications). • Printer is usable.
Causes: • Scanner drive motor driver defective • Scanner drive motor defective • Scanner home position sensor defective • Harness defective • Timing belt, pulley, wire, or carriage not installed correctly
Remedy: • Cycle the machine off/on. • Replace the part.
Code: SC141-00
Description: Black level detection error (Front) The black level cannot be adjusted when the initial adjustments of the CMOS sensor. This error is detected if the black level did not coverage within prescribed threshold after a specified number of adjustments.
Remedy: • Reconnect the power/signal harness. • Cycle the machine off/on. If the SC showed up again, try the following. • Replace the lens block. • Replace the BICU. • Replace the power/signal harness.
Code: SC142-00
Description: White level detection error (Front) The white level cannot be adjusted when the initial adjustments of the CMOS sensor. This error is detected if the white level did not coverage within prescribed threshold after a specified number of adjustments.
Causes: • SBU defective • LED defective • BICU defective • Power/signal harness defective • Scanner drive error • Condensation in scanner unit • Mirrors or lenses dirty or positioned incorrectly • White plate dirty or installed incorrectly
Remedy: • Clean the mirrors/white plate • Cycle the machine off/on. If the SC showed up again, try the following. • Reconnect the power/signal harness. • Reattach/clean the mirrors/lenses. • Reattach/clean the white plate. • Replace the lens block. • Replace the LED board. • Replace the BICU. • Replace the power/signal harness.
Code: SC144-00
Description: Scanner Communication Error (Front) • Connection to SBU cannot be confirmed. (Connection detection error) This error is detected if the releasing of the SBU reset did not confirmed after a specified time had passed. • Cannot communicate with the SBU, or the communication result is abnormal. This error is detected if the normal status was not responded in a specified number of communication.
Remedy: • Reconnect the power/signal harness. • Cycle the machine off/on. If the SC showed up again, try the following. • Replace the lens block. • Replace the BICU. • Replace the power/signal harness.
Code: SC151-00
Description: Black level detection error (Back) The black level detection error of the back side scanning sensor (CIS unit). This error is detected if even one pixel of the black level of the CIS unit did not coverage within prescribed threshold. The first and second consecutive occurrences of each constitute jams. The third occurrence constitutes an SC.
Causes: • CIS unit defective
Remedy: • Replace the CIS unit.
Code: SC152-00
Description: White level detection error (Back) The white level detection error of the back side scanning sensor (CIS unit). This error is detected if there were no shading data of the CIS unit in prescribed threshold. The first and second consecutive occurrences of each constitute jams. The third occurrence constitutes an SC.
Causes: • CIS unit defective • CIS background white roller/white plate dirty, positioned incorrectly • Power/signal harness defective
Remedy: • Clean the CIS background white roller. • Cycle the machine off/on. If the SC showed up again, try the following. • Replace the CIS unit. • Replace the CIS background white roller. • Replace the power/signal harness.
