077-111 IOT Exit Sensor ON Jam (Invert)
BSD-ON:CH10.10
In Invert Output Mode, IOT Exit Sensor does not turn ON in a spec time.
DC330 Code to Check
• [077-108] IOT Exit Sensor
• [077-013] Invert Motor
• [077-202] Invert Release Home Sensor
• [077-016] Release Motor
• [077-010] Exit Motor
Check Items
• Paper Path for a foreign object/burr/piece of paper
• Invert In Roll for dirt/paper particles/wear/a poor rotation
• Invert Roll for dirt/paper particles/wear/a poor rotation
• Drive gears for wear/breakage
• Check for out-of-spec paper.
• Drawer Connectors P/J608 contact points for foreign objects/bent pins/burnout
• Check the wire-wound resistance of Exit Motor is approx. 2.6 ohms at the measurement points
below.
– P222-2 pin to pins 1/3
– P222-5 pin to pins 4/6
• Check the wire-wound resistance of Invert Motor is approx. 2.6 ohms at the measurement points
below.
– P221-2 pin to pins 1/3
– P221-5 pin to pins 4/6
• Check the wire-wound resistance of Release Motor is approx. 10 ohms at the measurement points
below.
– P224-2 pin to pins 1/3
– P224-5 pin to pins 4/6
• Check the following for an open wire or poor contact:
– IOT Exit Sensor J111-2 to IOT PWB J438-A8
– IOT Exit Sensor J111-1 to IOT PWB J438-A9
– IOT Exit Sensor J111-3 to IOT PWB J438-A7
If the above wires are good, replace IOT Exit Sensor (PL 16.2) 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.
