HP Designjet 4000 Printer series - Manual (Page 189)

• Where you have two patterns next to each other which do not show
signs of banding, see below, use the patterns above and below these
two to help you select. For example, if the pattern above the two equal
ones contains less banding then choose the pattern just below it.
• Where you have three patterns which show no signs of banding, select
the middle pattern.
– If you look at part B of the print, you will probably see that it appears darker
in some patterns than in others. The best pattern is the one that appears
lightest, most uniform, and least grainy.
7.
Select the or icon, and then Paper advance calibration > Drawings/text
or Images > Select Pattern.
8. Select the number of the pattern (1 to 7) that printed best. If you found it difficult
to choose between two patterns e.g. patterns 3 and 4, then select “Between
pattern 3 and 4”
The calibration is complete.
After calibration
If you find that the paper advance calibration has reduced but not eliminated your print
quality problem, you could try step 7 again and select a different number. If you are
seeing light bands, try selecting a lower number than your original selection; if you are
seeing dark bands, try a higher number.
If you later want to cancel your calibration and restore the paper advance setting with
which the printer left the factory, select the
or icon, and then Paper advance
calibration > Drawings/text or Images > Select Pattern > Factory Default.
