HP Designjet Z5400 - If you still have a problem

Edges of objects are darker than expected
If edges of objects seem darker than expected, and you have already set the print-quality slider to Quality in
the driver dialog, select the custom print-quality options, and try setting the quality level to Normal. See
Printing on page 50.
Bronzing
If you are printing on photo paper in grayscale, and you experience a gloss differential problem when
fluorescent light is directly reflected towards you from the print, producing 'bronzed' reflections from the ink,
try one of the following:
●
If using standard print quality options, ensure that the slider is set to Quality (see
Printing on page 50).
●
Try selecting in the driver the Full set of inks option instead of Black and gray inks only.
●
Display the print vertically or behind glass.
Horizontal lines at the end of a cut sheet print
This type of defect affects only the end of a print, within approximately 30 mm of the trailing edge of the
paper. You may see some very thin horizontal lines across the print.
To avoid this problem:
1. Print the Image Diagnostics Print. See
The Image Diagnostics Print on page 141.
2. Consider printing with roll paper.
3. Consider using larger margins around your image.
Vertical lines of different colors
If your print has vertical bands of different colors along it:
1. Try using thicker paper, choosing from the recommended paper types such as HP Heavyweight Coated
Paper and HP Super Heavyweight Paper. See
Order paper on page 113.
2. Try using higher print-quality settings (see
Printing on page 50). For instance, if you have set the Print
Quality slider to Speed, try setting it to Quality.
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.
