Aligning the Print Head

Aligning the print head is the most important thing you can
do to ensure the best print quality. If banding appears on your
prints, if they look grainy or blurry, or you see misregistration
or "ghosting," you need to align the print head.
Although you can align the print head using the printer utility
software, it's best to align from the control panel. This will do
the most thorough job in the shortest time, and it's all
automatic.
If you haven't already done so, it's a good idea to run a nozzle
check before aligning the print head (page 9). This ensures
that the print head alignment patterns print correctly.
Follow these steps to align the print head using the control
panel:
1. Make sure the printer is turned on. Then load Epson
Enhanced Matte paper or the paper that came with the
printer.
Tip:
To properly align the print head, you can use letter-size Epson
Enhanced Matte Paper or Premium Luster Photo Paper.
2. Press the button.

It takes about 7 minutes to run the automatic uni-
directional head alignment. The printer's white beam sensor
reads the alignment pattern and adjusts the printer
automatically. Make sure you don't open the top cover or
turn off the printer during this process.

electronic Reference Guide for instructions.

Replacing the Paper Cutter Blade

blade may need to be replaced. If you use the blade to cut
heavy stock, you will damage the blade and need to replace it.

the cutter.
