4. Check that the settings under > Default printing conguration > Color options are correct. In
particular, test the default conguration, which is: Rendering intent = Perceptual, Black point compensation
= On, and HP Pantone emulation = On (unless other settings are desired).
5. Check that you are printing on the correct side of the paper.
6. Check that you are using appropriate print-quality settings (see Printing on page 59). 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.
7. If you are using Application Color Management, check that the color prole you are using corresponds to
the selected paper type and print-quality settings. If you have doubts about which color settings to use, see
Color management on page 87.
8. If a grayscale image shows a color cast in some of the gray shadows, select Color > Grayscale in the driver.
9. If the problem consists of color dierences between your print and your monitor, try calibrating your
monitor. At this point, you may wish to reprint your job in case the problem has been solved.
10. Print the Image Diagnostics Print. See Image Diagnostics Print on page 175.
If the problem persists despite all the above actions, contact HP Support: see Contact HP Support on page 193.

Image is incomplete (clipped at the bottom)
● Did you tap before all the data were received by the printer? If so, you have ended the data
transmission and will have to print the page again.
● If a large image is clipped (A1 or larger), go to the Advanced properties in the driver, then set Max
application resolution to 300.
● The I/O timeout setting may be too short. This setting determines how long the printer waits for the
computer to send more data, before deciding that the job is nished. From the front panel, increase the I/O
timeout
setting to a longer period and then send the print again. Tap , then Connectivity > Network
> I/O timeout.

network cable.
