Corrective action
1. Clean any faulty printheads (see Clean the printheads on page 146). 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 146). 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 noties 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 147.
5. If the problem still remains, replace any persistently faulty printheads (see Handling ink cartridges and
printheads on page 97), or contact HP Support (see Contact HP Support on page 159).
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 47.
● 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/T1700/drivers.
● 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 rmware is up to date. See Update the rmware on page 110.
● Check that you have the right settings in your software application.
