Troubleshooting Print Quality Problems
If your paper type has different versions in the front panel with more and less
ink, select the one with less ink.
8 Try to increase the margins by relocating the image to the center of the page
with the software application being used.
9 If horizontal smearing occurs when you are using Photo Gloss or Semi-Gloss
papers, try setting the carriage position to HIGH. To set the carriage position
to HIGH, create a custom paper type according to the following procedure:
a From the HP Easy Printer Care (Windows) or HP Printer Utility (Mac OS),
create a custom paper type based on the paper type that resulted in
horizontal smears (for Photo Gloss or Semi-Gloss papers ONLY). For more
information on creating custom paper types, see the User´s Guide.
b Go to Change Printing Properties and select the paper that you just
created.
c Change the paper thickness to the highest setting.
d Select the custom paper type from the Front Panel and align the
printheads (
see Aligning Printheads, Page 1-66)
e Check that the custom paper type is selected from the Front Panel and
perform a Color Calibration.
f If the customer prints with ICC profiles, create a new ICC profile.
g Try printing the project again using the new custom paper with the
carriage position set to HIGH.
10 If the horizontal smearing occurs when you are using Digital Fine Art paper,
the cause of the problem may be the environmental conditions. Check that
the humidity and temperature are within specifications for both the printer
and the paper.
11 If the humidity and temperature are OK, install the Extra High PRS Wedge.
The Extra High PRS Wedge increases the distance between the printhead
and the paper and can help eliminate horizontal image smearing problems.
When you name the paper type, it is a good idea to use the
paper’s commercial name and something indicating the
high carriage setting.
The new Extra High PRS Wedge can be ordered using Part
Number Q5669-67055. For the relevant removal and
installation procedures, see page 6-109.
