3. Follow the on-screen instructions, then click
Print to print the nozzle check
pattern. Compare the nozzle check pattern to the sample pattern on the
computer.
If the nozzle check pattern indicates that the nozzles are clogged, clean the
print head.
Cleaning the Print Head
If print quality has declined and the nozzle check indicates clogged nozzles, you
can clean the print head using the Head Cleaning utility in your driver software.
Print head cleaning uses ink, so clean it only if necessary.
Note:
You cannot clean the print head if an ink cartridge is expended, and may not be able to
clean it when a cartridge is low. You must replace the cartridge first (see page 31).
Caution:
OS X: Do not use the Clean Print Heads button on the Utility tab of the driver to
perform head cleaning on the P400. Use the Head Cleaning utility in the Epson Printer
Utility 4, as described below.
1. Load a few sheets of plain paper in the sheet feeder (see page 5).
2. If you have just completed a nozzle
check, click
Clean in the Nozzle Check
dialog. Otherwise, do one of the
following:
Windows: Right-click the icon in the
bottom right corner of your screen (the
taskbar) and select
Head Cleaning.
OS X: In the Apple menu or the Dock,
select
System Preferences. Select
Printers & Scanners, Print & Fax, or
Print & Scan, select your product, and
select
Options & Supplies. Select the Utility tab, then select Open Printer
Utility
. Select Head Cleaning.
3. Follow the on-screen instructions, then select
Start.
Cleaning lasts around 2 minutes. When it’s finished, you see a message on the
screen.
Caution:
Never turn off the product during head cleaning or you may damage it.
