Cleaning and recalibrating the copier/scanner
Recalibrating the copier/scanner
The optional copier/scanner automatically calibrates to the white
sheet opposite the image sensor at the beginning of each scan or
copy job.
Keep the white sheet clean to make sure the optional copier/scanner
calibrates correctly. See “Cleaning the scanner path” on page 51 for
information about cleaning the white sheet.
Cleaning the scanner path
You might have to clean the copier/
scanner if:
! You can smudge the ink on
documents you scan.
! The documents have excessive
amounts of dust or dirt on them.
! There are smudges or other marks
on documents or scans of
documents.
! The scanned output has lines or
defects that were not on the original.

of the image sensor. If you inadvertently
touch the glass, clean it according to the
