HP Designjet Z6100 Printer series - Manual (Page 165)

Humidity can cause ink to soak into the paper, making the lines look blurred and fuzzy. Try the following
remedies:
1
. Make sure that your environmental conditions (temperature, humidity) are suitable for high-quality
printing. See Environmental specifications on page 191 .
2
. Verify that the paper type that you select on the front panel is the same as the paper type that you
are using. To check, select the icon from the printer's front panel, and then select View loaded
paper.
3
. Try changing to a heavier paper type, such as HP Heavyweight Coated Paper, HP Super
Heavyweight Coated Paper, or Digital Fine Art paper.
4
. If you are using glossy paper, try changing to a different type of glossy paper.
5
. Align the printheads. See Align the printheads on page 71 .
Lines are slightly warped
The paper itself might be warped. This can happen if it has been used or stored in an extreme environment.
See Environmental specifications on page 191 .
Dark or light horizontal lines across the image
(banding)
Try the following remedies if your printed image suffers from added horizontal lines as shown (the color
may vary):
1
. Make sure that the paper type you have loaded corresponds to the paper type that you select on the
front panel and in your software.
2
. Make sure that you are using appropriate print-quality settings for your purposes. See Select print
quality on page 80 . In some cases, you can overcome a print-quality problem merely by selecting a
higher print-quality level. For instance, if you have set the print-quality slider to Fast, try setting it
to Best. If you change the print-quality settings, reprint your job if the problem has been solved.
3
. Print the Printhead status plot. See Use the Printhead status plot on page 71 .
