Paper does not feed - paper feed motor turns in only one direction
•
When paper is fed from the input tray, the paper feed motor
rotates counterclockwise actuating the paper lifters, followed by
a clockwise rotation.
•
When feeding from the manual tray, the paper feed motor
rotates in only one direction. If, when paper is fed from the input
tray and the motor turns in one direction only, replace the
engine board.
Action
Check the clutch lever for obstructions and the
gear box for binds and wear. Replace worn or
binding gears.
Check for binds in the gear train and paper feed
mechanism by rotating the large feed roll by hand.
If you notice a bind, isolate it by removing one of
the small idler gears on the inside of the left side
frame. Replace any worn or binding gears or
rollers.
Be sure that the large feed roller is clean.
Check the paper lifters, pads and paper tray for
proper positioning.
Check for correct position of the left paper adjuster
guide lifter assembly.
