Chapter 10 Troubleshooting
Cannot send image files to
devices and folders on different
segments of the network.
Cause
A ScanFront Service Server does not exist on the network. (A
ScanFront Service Server has not been configured or is not running.)
Solution
Install ScanFront Service on a computer on the same network as the
scanner. (See p. 4-3.) If a ScanFront Service Server has been
implemented, check the necessary settings. In addition, you must start
the ScanFront Service Server before turning ON the ScanFront. (See
p. 4-6.)
Scan
Streaks appear in images
Cause The scanning glass is dirty.
Solution
Clean the scanning glass. (See p. 9-3.) If there are scratches on a
scanning glass, contact your local authorized Canon dealer.
Paper becomes jammed
Cause The rollers are dirty.
Solution Clean the rollers. (See p. 9-3.)
Paper jams occur frequently
Cause The rollers (consumable parts) have worn out.
Solution
Purchase an Exchange Roller Kit and then replace the rollers. (See
p. 9-8.)
Documents are double fed
Cause
Static electricity is causing the pages of the document to stick to each
other.
Solution Before you load a stack of documents, fan the documents.
Cause The type of paper of the documents is causing a paper feed error.
Solution
Load no more than ten pages of documents. (See p. 2-10.) Use bypass
feeding to scan the pages one by one.
A stack of documents are fed
together
Cause The feed selection lever is set to Page Separation OFF. (See p. 2-5.)
Solution Set the feed selection lever to page separation feeding.
Scanning starts immediately
after I press a job button (certain
users only)
Cause
The job buttons are designed to work that way. See “Skip Scan Setting
Screen” on p. 6-21 and p. 8-17.
Solution Place the document and then press a job button.
