TECHNICAL BULLETIN
Countermeasure against paper jams resulting from the inactive pickup solenoid and feed roller clutch

1. Model Name

AR-M256/316 AR-M236/276

2. Content

If the 24V line (red) of the 15-pole connector pin contacts with the chassis, the chip fuse on the MCU PWB burns out. Since 24V is not supplied to the solenoids and clutch, they are inactive. It may cause paper jam. Check if the 24V line (red) of the 15-pole connector pin contacts with the chassis as shown below. In case of contact, the 24V line and chassis are short-circuited. It causes burnout of the chip fuse on the MCU PWB.

3. Description

To prevent the 15-pole connector from contacting with the chassis, wiring treatment has been changed as shown below. A band (LBNDJ0013FCZ1) is required for change of wiring treatment.

4. Market action

When the fuse has burned out, replace the chip fuse (QFS-L0002QSZZ) or MCU PWB. When servicing the machine, check the 15-pole connector position and change the wiring treatment. Executed from the middle of production in May, 2007
