Fault
Description
Recording paper is jammed in the output area (inside the fuser), or multiple sheets of the paper are
fed at once.
Jam 1
Model ML-xxxx
Check
Engine board
Cause
1. Open the printer cover, and close it. Then check :
- If the paper does not feed into the printer, the feed clutch driving circuit in the engine board may
be defective.
- If the paper feeds into the printer and ‘Jam 1’ occurs, the feed sensor OP1 on the engine board
may be defective.
- If paper is stopped in just front of fuser:
1-1. Feed sensor OP1 or feed actuator may be defective.
1-2. Exit sensor OP3 or exit actuator may be defective.
2. In case of multi-feeding, refer to Error Code 2-050.
Solution
1-1. Check the feed sensor OP1. Refer to Error Code 2-020. Replace the feed actuator if defective.
1-2. Check OP contacts. In operating mode, U6 (74HC245) pin#13 should be below 0.7V. If not, check
OP3 contact resistance. Replace OP3 if over 100 ohms. If the switch works normally, check R30.
If defective, replace the exit sensor actuator.
2. In case of multi feeding, refer to Error Code 2-050.
