feed documents
Make sure that:
•
the power cord is plugged in and the power is on.
•
the side access door and pod are completely closed.

the printer access door (Scanner 3520DP or Color Scanner
4500DP) is completely closed.
•
the proper power-up sequence was followed and the software has
enabled scanning.
•
the top green indicator light on the front panel is on.
•
documents are making contact with the feed module.
•
the height of batched documents is less than:
±
15.2 mm (0.6 in.) on a scanner using the Feed Module 150.
±
25.3 mm (1.0 in.) on a scanner using the Feed Module 250.
•
for documents stacked near the maximum heights listed above, you
position the batch 12.7 mm (0.5 in.) away from the baffle housing.
•
documents meet specifications for size, weight, and height of
