PAPER THICKNESS
You can adjust the thickness of the paper to use. If you use Epson
special media and its paper thickness is 0.2 mm or 1.2 mm, select
STANDARD. If you use non-Epson special media, enter the paper
thickness in the range of 0.1 to 1.5 mm.
ALIGNMENT
You can correct any head misalignment to obtain optimum
printing results. For details, see “Aligning the print head” on page
225.
Checking the print head nozzles
To find out if the 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. To
print a nozzle check pattern, follow the steps below.
Note:
If you want to perform an auto nozzle check before printing for each
print job, select ON for AUTO CLEANING and then select ON for
AUTO NOZZLE CHECK.
Before you start printing your data, make sure that nozzle check
pattern printing is complete; otherwise, the print quality may
decline.
