Canon imageFORMULA DR-G1130 Manual

6-8

Problem Lines, smudges, or dirt appear on the 

scanned image.

Cause

The scanning glass or rollers inside the 
scanner are dirty.

Solution

Clean the scanning glass and rollers. 

If lines still appear on the image even after you 
clean the scanning glass and rollers, the 
scanning glass inside the scanner may be 
scratched. Contact your local authorized 
Canon dealer or service representative.

Problem The scanned image is abnormal for 

certain documents.

Cause

A detection function such as border 
removal is enabled when scanning a 
document that includes text or photos 
extending to the edge of the page (the 
scanner cannot accurately process the 
edges of documents).

Solution

When a page has text or photos extending to its 
edges, turn the detection functions off or scan 
that page individually.

Problem The scanned image is abnormal in some 

applications.

Cause

A function not supported by the 
application was used.

Solution

Some applications do not support functions 
such as auto-detection of page size, so 
scanning with such applications will produce 
abnormal scanned images.
If abnormal image appearance seems to be 
application-dependent, try scanning with auto-
detection disabled.

Problem There are white lines or streaks in the 

scan image. 

Solution

Clean the scanning glass (both front and back) 
and the rollers (feed roller and retard roller). 
When cleaning adhesive dirt such as glue or 
corrective fluid, try wiping the streaky areas 
with considerable vigor. If the problem has not 
been solved after cleaning, it is possible that 
the scanning glass is scratched. Contact your 
vendor or service center.
