Print quality troubleshooting
6 Print the Service Image Diagnostics Print, and clean any printheads that
need cleaning. Reprint the job in case the problem has been solved
.
Color accuracy using EPS or PDF images in page layout
applications
Page layout applications such as Adobe InDesign and QuarkXPress do not
supp
ort color management of EPS, PDF, or grayscale files.
If these types of files have to be used, try to ensure that the EPS, PDF, or
gra
yscale images are already in the same color space that is intended to be
used later on in Adobe InDesign or QuarkXPress. For instance, if the final
objective is to print the job in a press that follows the SWOP standard, at the
time of creating the EPS, PDF or grayscale the image should be converted
into SWOP.
Output Only Contains a Partial Print
If the output that was expected only contains a partial image, then try the
f
o
llowing to resolve the problem:
1 Was the Cancel key pressed before all the data was received by the Printer?
If so, send the file again and make sure that the
Cancel key is not pressed.
2 The I/O Timeout setting may be too short. Increase the I/O timeout setting
(Setup Menu/I/O Setup/IO Timeout) and then send the file again.
3 There might be a communications problem between the Printer and
C
omputer. Check the USB or network cable between the computer and the
Printer to make sure it is not damaged and is connected correctly.
4 Mak
e sure that the software settings are correct for the current page size
(e
.g. long-axis prints).
5 If network software is being used, make sure it has not timed out.
P
roblems with Image Clipping
This normally indicates a discrepancy between the actual printable area on
the loaded paper
and the printable area as understood by the software. This
kind of problem can often be identified before printing by previewing the
print.
 Check the actual printable area for the paper size that is loaded.
printable area = paper size – margins
 Check what the software understands to be the printable area (which it
may call “printing area” or “imageable area”). For example, some
software applications assume standard printable areas that are larger
than those used in this Printer.
 If a custom page size with very narrow margins has been defined, the
printer may impose its own minimal margins, clipping the image slightly.
Consider using a larger paper size, or border less printing.
 If the image contains its own margins, it may be possible to print it
successfully by using the Clip Contents by Margins option.
 If a very long image needs to be printed on a roll, check that the software
is capable of printing an image of that size.
 The page may have been rotated from portrait to landscape on a paper
size that is not wide enough.
