SYMPTOM
Jam 004 (misfeed) occurs.
CAUSE
1. The customer uses an unsupported thin paper type (approx. 0.33gsm or thinner), which
causes the ADF feed unit to interfere with the movement of the pick-up roller. As a
result, the pick-up roller cannot be lowered to the proper position.
OR:
2. The separation cushion is not attached properly at the factory, causing the Mylar to
stick outside the feed area [A]. As a result, the original catches on the Mylar.
