If you have not used your printer
for more than six months
O When activating AUTO NOZZLE CHECK in the
panel settings, the printer checks the print head
nozzles for clogging, and performs print head
cleaning automatically if needed.
O If you have not used your printer for a long time,
print a nozzle check pattern to check for clogging.
If the nozzle check pattern is not good, perform
head cleaning before printing your data.
See “Nozzle check” on page 77
See “Head cleaning” on page 79
See “Power cleaning” on page 81
O You need to perform head cleaning a few times
before the nozzle check pattern is correctly
printed. If the nozzles are still clogged after
performing head cleaning three times, perform
power cleaning.
See “Head cleaning” on page 79
See “Power cleaning” on page 81
O After performing the head cleaning a few times,
turn off the printer and leave it overnight or
longer, so that the ink may dissolve.
O If the nozzles are still clogged after trying the
instructions above, contact your Epson dealer.
Protecting the print head
This printer has a capping function that automatically
puts a cap on the print head to keep it away from
drying.
If the print head is left uncapped, the print quality may
decline. When you are not using the printer, make sure
the print head is located on the far right so that it is
capped.
See “Capping function” on page 82
