Problem

description

Cause Solutions

The banding affects

mostly dark or

saturated colors.

If banding is only in area

fills near the edges of

the substrate, the cause

could be insufficient drying

of the ink.

• If possible, reduce the ink quantity in

your RIP options.

• Use a higher number of passes.

• You can also reduce the ink quantity

of these colors.

Banding in any area of the

job could be caused by an

inaccurate color profile.

Optimize black and dark colors using

HP media presets or creating a new

media preset following the

recommendations stated in the

Color

reproduction tricks section.

Misaligned colors or lack of sharpness

Problem description Solutions

Colors look shifted in any direction or

text, lines or solid areas are rough or

blurred.

• The printheads could be misaligned. This is likely if

you have not aligned the printheads for a long time,

you have performed the alignment with another

substrate or there has been a substrate jam.

• Perform printhead alignment. Select the icon,

choose “Image Quality Maintenance”, then “Align

Pritnheads” and “Auto PH alignment”.
