4. Poor contact in the PICK-UP SOLENOID DRIVE signal line connector.
Action: Reconnect the pick-up solenoid connector J306 and the connector J211 on the
paper deck driver PCB.
5. Pick-up motor failure.
Action: Replace it.
6. Pick-up solenoid failure
Action: Disconnect the pick-up solenoid connector J306. Measure the resistance between
the connector J306-1 and J306-2 cable side. If it is not about 190 Ω, replace the
pick-up solenoid.
7. Paper deck driver PCB
Action: Replace it.
J-2 Feed unit
< possible causes >
1. Feed guide is dirty, cracked, or deformed.
Action: Clean it if dirty, or replace it if cracked or deformed.
2. Registration roller or Feed roller 2 is worn, deformed, or dirty.
Action: Clean them if dirty, or replace them if worn or deformed.
3. Registration paper sensor lever is damaged.
Action: Replace it if damaged.
4. Paper jam sensor lever is damaged.
Action: Replace it if damaged.
5. Poor contact in the REGISTRATION CLUTCH DRIVE signal line connector.
Action: Reconnect the registration clutch connector J303 and the connector J208 on the
paper deck driver PCB correctly.
6. Poor contact in the REGISTRATION PAPER DETECTION signal line.
Action: Reconnect the registration paper sensor connector J309, intermediate connector
J308, J304 and the connector J209 on the paper deck driver PCB correctly.
7. Poor contact in the PAPER JAM DETECTION signal line.
Action: Reconnect the paper jam sensor connector J310, intermediate connector J308,
J304 and the connector J209 on the paper deck driver PCB correctly.
8. Registration paper sensor failure.
Action: Perform the sensor checks described on page 4-7 to check whether the sensor is
normal. Replace the registration paper sensor if it is not normal.
9. Paper jam sensor failure
Action: Perform the sensor checks described on page 4-7 to check whether the sensor is
normal. Replace the paper jam sensor if it is not normal.
10. Registration clutch failure
Action: Disconnect the registration clutch connector J303. Measure the resistance between
4 - 10
