140 Printing with Mac OS 9.x
If you click Auto in the Nozzle Check dialog, or turn on AUTO
CLEANING from the control panel on the printer, this utility not
only checks the clogging nozzles, but also performs head cleaning
automatically.
Head Cleaning
This utility cleans the print head. You may need to clean the print
head if you notice the print quality has declined. Use this utility
to perform head clean. See “Cleaning the print head” on page 142.
Print Head Alignment
This utility can be used to improve the print quality of your
printed data. The alignment of the print head may need to be
adjusted if vertical lines appear out of alignment or if white or
black banding noise appear in your printed data. Use this utility
to realign the print head. See “Aligning the print head” on page
143.
Configuration
Clicking this button opens the Configuration Settings dialog,
where you can change the way the EPSON Status Monitor utility
notifies you when the printer status changes. See “Making
Configuration Settings” on page 146.
Checking the print head nozzles
If you find that the printed data is unexpectedly faint or dots in
the printed data are missing, you may be able to identify the
problem by checking the print head nozzles by using the Nozzle
Check utility.
To use the Nozzle Check utility, follow the steps below.
