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 and Copy settings sections of the User Guide.
2. If the problem persists, see Preventive maintenance on page 529 to see how to clean the scanner, and
see Support Menus, Diagnostic Plots & Calibrations on page 181 to see how to Calibrate the scanner.
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 (300dpi or less), and a lower
compression le format
4. If the problem persists, see Preventive maintenance on page 529 to see how to clean the scanner, and
see Support Menus, Diagnostic Plots & Calibrations on page 181 to see how to Calibrate the scanner.
Check that the maintenance sheet is also clean, and that it is not damaged before calibrating the
scanner (an old or damaged maintenance sheet may cause this problem); if it is damaged, reprint it.
