Nozzle Check
To find out if nozzles are delivering ink properly, you can print a
nozzle check pattern. If the nozzles are not delivering ink
properly, missing dots will be evident in the print pattern. Six
nozzles can be checked at a time.
Caution:
c
Before you start printing images, make sure that nozzle check
pattern printing is complete. Otherwise, print quality may
decline.
Head Cleaning
When printing quality declines, or when clogged nozzles are
evident after the nozzle check, the print heads need to be cleaned.
Use this utility to perform the head clean, then perform the Nozzle
Check again, as repeat head cleaning may be 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.
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. See "Using Printer and Option Information (Windows only)"
on page 51.
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.
