  • Double Feed

Occurred the double feed

1. Check that Cassette Locking is right position.

2. Check that papers are properly installed and held in paper tray.

Check the condition of Rubber-Pick

NO

YES

YES

if worn out the rubber, replace Rubber-Pickup, if contaminated rubber, clean up the rubber with alcohol or replace

Adjust the Cassette/papers to the right position

NO

NG

OK

Re- printing OK/NG?
