There is banding on new media The printer requires calibration for the
new media. Adjust the printer settings for the new
media (Refer to
Calibrate the printer )
There is banding on media that has been
calibrated and did not give banding
before. If one of the following is true, try the
corresponding solution and if banding
has not disappeared, then go to the next
possible cause and solution:
1. The file you are printing:
a) is new
b) is not new
2. The print mode:
a) has changed
b) has not changed
3. Normal printhead recovery:
a) did not improve banding
b) improved banding
4. Strong printhead recovery:
a) did not improve banding
b) improved banding
Try one of the following solutions:
1. a) Try using a file that did not give
banding. If banding does not disappear,
then see the next possible cause.
b) Check that you are using the same
print mode as before.
2. a) Try using the same print mode. If
banding does not improve, then try a new
roll of media. If you still see banding call
HP support.
b) Try normal printhead recovery. If
banding improves, repeat normal
printhead recovery until no improvement
is seen and banding is still present. Call
HP support.
3. a) Print the IQ print and check whether
there are any printhead nozzles not
working. If some printheads are not
working, try strong printhead recovery for
the affected printheads.

b) Repeat normal printhead recovery
until no improvement is seen and
banding is still present. Call HP support.
