073-105 Regi Sensor ON Jam (Tray 3)
Bsd-on:CH8.11

Paper from Tray 3 does not turn ON Regi Sensor within a spec time.

DC330 Code to Check
[077-104] Regi Sensor

[077-004] Pre Regi Motor

Check Items
Paper Path for a foreign object/burr/piece of paper

Pre Regi Roll for dirt/paper particles/wear/a poor rotation

Drive gears for wear/breakage

Check for out-of-spec paper.

Drawer Connectors P/J601 contact point for foreign objects/bent pins/burnout

Check the wire-wound resistance of Pre Regi Motor is approx. 0.8 ohm at the measurement points.

P229-2 pin to pins 1/3

P229-5 pin to pins 4/6

Check the following for an open wire or poor contact:

Regi Sensor J122-2 to IOT PWB J439-B11

Regi Sensor J122-1 to IOT PWB J439-B12

Regi Sensor J122-3 to IOT PWB J439-B10

If the above wires are good, replace Regi Sensor (PL 13.4) and Flexible Print Cable (PL 2.1) in order.

If the results of the above checks are OK, replace IOT PWB (PL 2.1) and MCU PWB (PL 2.1) in order.
