Countermeasure against "L1-00"trouble due to detection
error of the MHPS PWB
1. Model Name
"L1-00" scanner feed trouble may occur during operation of the main unit.
If the lead wire of the capacitor (C1) on the MHPS PWB contacts with the plate of the
optical unit, the sensor on the MHPS PWB generates a detection error, and it results in
"L1" scanner feed trouble.
We reviewed necessity of the capacitor (C1) mounted on the MHPS PWB. As a result,
we confirmed that there were no problems with the performance even if it was disused.
Therefore, the capacitor (C1) has been disused to avoid "L1-00" scanner feed trouble
due to contact of the capacitor's lead wire with the plate of the optical unit.
Note: Even if the MHPS PWB has an old parts code, it is a modified PWB if the
