Corrective action
1. Clean any faulty printheads (see Clean the printheads on page 141). Then reprint the Image
Diagnostics Print to see whether the problem has been solved.
2. If the problem remains, clean the printheads again, and reprint the Image Diagnostics Print to see
whether the problem has been solved.
3. If the problem remains, consider cleaning your printheads manually (see
Clean the printheads
on page 141). You could also try reprinting your current print job, in case it now prints satisfactorily.
4. If the problem remains, try cleaning the printhead drop detector. The printer normally notifies you
when this is necessary, but it may be worth trying even if the printer has not suggested it. See
Clean the printhead drop detector on page 142.
5. If the problem still remains, replace any persistently faulty printheads (see
Handling ink cartridges
and printheads on page 81), or contact HP Support (see Contact HP Support on page 160).
If you still have a problem
If you still experience print-quality problems after applying the advice in this chapter, here are some
further things that you can do:
●
Try using a higher print-quality option. See
Printing on page 41.
●
Check the driver you are using to print with. If it is a non-HP driver, consult the driver vendor about
the problem. You could also try using the correct HP driver, if feasible. The latest HP drivers can
be downloaded from
http://www.hp.com/go/designjet/.
●
If you are using a non-HP RIP, its settings may be incorrect. See the documentation that came with
the RIP.
●
Check that your printer's firmware is up to date. See
Update the firmware on page 100.
●
Check that you have the right settings in your software application.
