Light colored area lls are missing in the scan or copy
When scanning or copying a map with a light area at the top, the Background color removal setting could
interpret it as a background color, therefore removing it and other similar areas. The example below shows
the original image on the left and the scanned image on the right.
Actions
1. Repeat the scan or copy with Background color removal set to O, or, in the case of copying, you can
select Image as the content type. See Scan settings on page 61 and Copy settings on page 72.
2. If the problem persists, clean and calibrate the scanner as indicated in Clean the scanner scanbars
on page 111 and Calibrate the scanner on page 112. Repeat it again with Background color removal set
to O.
Grain in area lls when scanning plain paper
When making copies of an original containing area lls, if the paper used in the printer is plain paper (for
instance, HP Universal Bond or HP Bright White Inkjet Bond), some grain may appear in the image. This error
may also appear in scanned les of originals that were printed on textured paper. The example below shows
the original image on the left and the scanned, grainy image on the right.
Actions
1. Please look at the original and check if it is dirty, has ngerprints on it or if the grain is already present in
the print. If not, then proceed to step 2.
2. If it is a copy, repeat it, setting the content type to Image.
3. If the problem persists:
●
If the problem appears when copying, use Best quality. We also recommend using coated or glossy
paper in order to avoid grain in copies.
●
If the problem appears in a scanned le, scan at a lower resolution (300 dpi or lower resolution).
4. If the problem persists, clean and calibrate the scanner as indicated in Clean the scanner scanbars
on page 111 and Calibrate the scanner on page 112. Check that the maintenance sheet is also clean, and
