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 165 .
5. If the problem still remains, replace any persistently faulty printheads (see Handling ink
cartridges and printheads on page 112 ), or contact HP Support (see Contact HP Support
on page 182 ).
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 49 .
● 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/T770/drivers/ or http://www.hp.com/go/
T1200/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 firmware is up to date. See Update the firmware on page 125 .
● Check that you have the right settings in your software application.
