Cleaning Inside the Scanner
If paper jamming, marking, or multiple-sheet feeding occurs frequently, clean the rollers, sensors and
double feed detector as described in this section. To maintain scanning quality, clean the scanner
components frequently: Clean inside the scanner at least once per week or after 20,000 sheets have been
scanned, whichever comes first.
To determine the number of sheets scanned, use the
Tr
ū
per User Utility. (See
“Tr
ū
per User Utility” on
page 98
.)
The following guidelines are for cleaning inside the scanner:
•
If the documents you scan are dirty, the scanner’s parts and components will also become dirty.
Be sure the documents you scan are as clean as possible.
•
When scanning with the flatbed, if black dots or white patches appear in the scanned results,
open the document cover and clean the flatbed glass and flatbed sheet using the roller cleaning
paper.
•
If black or white lines appear on the scanned images, clean the ADF glass areas and the
reference plates as described in
“Cleaning the Background Color Reference Plates and ADF
Glass” on page 85
.
•
Clean the flatbed glass and document cover detector as described in
“Cleaning the Flatbed
Glass and Document Cover Detector” on page 90
.
•
If paper jamming, marking, or double feeding occurs frequently even after cleaning, you may
need to change the rollers, as described in
“Replacing Consumables” on page 92
.
Also observe the warnings for use of the roller cleaning paper shown in
“Roller Cleaning Paper” on
page 78
.
