Background on copies – Examine the input document for the source of the problem.
– Ensure that the document is held flat on the Document Glass and
that the document cover is closed.
– From the Image Quality tab, adjust the Lighter/Darker control to
lighter.
– When making Black copies, select Black as the output color.
Reduce the color Balance-Low Density values so that the
background does not appear on the copies.
– When copying colors, set the Output Color to Auto Color and
select Auto Exposure so that the background does not appear
on the copies.
– Determine the type of document you are copying. From the
Original Type feature, indicate whether the original is Photo &
Text, Text, Photo or other color originals (Maps) for best copy
quality.
NOTE: You can select the Photo option for documents other than
photographs if the document contains areas of different density, from
light to dark, and all levels of density need to be copied.
The copies are blurred
when copying thick
documents, three-
dimensional objects, or
books – Increase the Sharpness.
– Select the Text or Other Color Originals (Maps) option in the
Original Type feature
– Ensure that the document is held flat on the Document Glass and
that the Document cover (DADF) is closed as much as possible.
DO NOT force the cover closed.
Copies have dark
bands on the lead edge
and a corner when
100% Reduce/Enlarge
is selected. – The bands may be caused by curled edges on the document or
by misregistration of the document on the Document Glass.
– Ensure that the document is registered correctly.
– Ensure that the Border Erase is at No Erase (2mm). Increasing
the amount of the Border Erase should remove more of the dark
bands. Increasing the amount of Border Erase, however, may
eventually cause image loss.
