White spots on the print
You may notice white spots on the print. This is probably due to paper fibers, dust or loose coating
material. To avoid this problem:
1. Try cleaning the paper manually with a brush before printing, to remove any loose fibers or
particles.
2. Always keep the cover of your printer closed.
3. Protect your paper rolls and sheets by storing them in bags or boxes.
Colors are inaccurate
If the colors of your print do not match your expectations, try the following:
1. Check that the paper type you have loaded corresponds to the paper type selected in the front
panel and in your software. To check on the front panel, use the View loaded paper key. At the
same time, check the color calibration status. If the status is PENDING or OBSOLETE, you
should perform color calibration: see
Color calibration on page 66. If you have made any
changes, you may wish to reprint your job in case the problem has been solved.
2. Check that you are printing on the correct side of the paper.
3. Check that you are using appropriate print-quality settings (see
Printing on page 43). If you have
selected the Speed or Fast options, you may not get the most accurate colors. If you change the
print-quality settings, you may wish to reprint your job at this point in case the problem has been
solved.
4. If you are using application-managed colors, check that the color profile you are using
corresponds to the selected paper type. If you have doubts about which color settings to use,
see
Color management on page 59. If you need to create a color profile, see Color profiling
on page 67.
5. If you select application-managed colors in your application and printer-managed colors in the
printer driver, your results will be wrong. You should manage colors in the application or in the
printer, but not in both.
6. If the problem consists of color differences between your print and your monitor, please follow
the instructions in the “How to calibrate your monitor” section of the HP Color Center. At this
point, you may wish to reprint your job in case the problem has been solved.
7. Print the Image Diagnostics Print. See
The Image Diagnostics Print on page 155.
If the problem persists despite all the above actions, contact your customer service representative for
further support.
