Caution:
Before you start printing images, make sure that the nozzle check
pattern printing is complete. Otherwise, print quality may
decline.
Head Cleaning
If printing quality declines, or if clogged nozzles are evident after
the nozzle check, the print heads need to be cleaned. Use this
utility to perform the head cleaning, then perform the nozzle
check again to see if a repeat head cleaning is necessary.
Print Head Alignment
Print head alignment is necessary when a misalignment of
vertical lines appears in the head alignment test pattern, or when
banding is evident in your printouts.
Note:
Make sure that the printer is finished printing before performing the
Nozzle Check, Head Cleaning, or Print Head Alignment utilities.
Otherwise, your printout may be marred.
Printer and Option Information (Windows only)
This utility allows the printer driver to confirm printer
configuration information. It also provides specific information
regarding certain characteristics of the printer, such as the Printer
ID.
Depending on the configuration of your system, the information
displayed in the Printer and Option Information dialog box may
be updated automatically, or may need to be updated manually.
