施乐4112卡纸，有时候几张就卡，有的时候1、2千张都没事，每次的卡纸代码都是077-111，请问是哪里的问题？

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.
