Problem
Possible Solution
The scanner will not scan/
feed documents
Make sure that:
• the wall outlet is not defective.
• the power cord is plugged in and the power is on.
• the scanner cover is completely closed.
• the PC was restarted after installing the software.
• the proper power-up sequence was followed, the
scanner’s green light is on, and the software has
enabled scanning.
• documents are making contact with the feed
module.
• the number of documents is less than
approximately 40 sheets of 24 lb bond (90 g/m2)
paper.
• documents meet specifications for size, weight,
and type, etc.
• for thicker documents, you lift the gap release
lever during feeding.
• you check the feed module and separator module
for signs of wear, and replace these parts if
necessary.
• you try powering the scanner down, and then up
again.
If you are feeding a stack of documents (more than
40) at a 25 degree angle, and the transport will not
start, it may be necessary to shingle (stagger) the
bottom documents so the feed rollers can grasp the
first document and start the feeding process.
