Paper jams at entrance to Conveyor
Paper emerges from the Dryer, and when entering the Conveyor, it crumples up at the
Conveyor’s input area, or a corner is folded.
Causes and things to check:
-
Conveyor Input Rollers are misaligned with the space between the Upper and
Lower Decks of the Conveyor.
o Pull the Conveyor out, and feed a small piece of flat paper into the
Conveyor’s Input Rollers while they are moving. Watch the paper as it
goes into the narrow slot between the Upper and Lower Plates of the
Conveyor. The paper should be just level with the top of the Lower Plate
as it goes from the pinch of the Rollers into the narrow slot.
-
Paper is damaged inside the Dryer before it emerges, and this damage causes
jams at the entrance to Conveyor.
o Pull the Conveyor out, and let some prints emerge from the Dryer without
the Conveyor in place. Check these prints for folded corners or other
damage. If they are damaged, the problem is starting in the Dryer, or
even earlier in the paper path (Processor, Print Engine).
-
Top plate sagging into paper path.
o Steel Pivot Pin loose on top plate
o The screws holding pin block are loose.
-
Input rollers to Conveyor not turning.
o Check for loose pulleys
o Loose drive belt from Motor to Rollers
o PCC Input Motor not turning.
