Cleaning The Print Head; Maintenance And Transportation - Epson EPI-4000 User Manual

Cleaning the Print Head

The EPI-4000 offers a print head cleaning cycle to ensure that all the
print head's ink nozzles deliver ink correctly. Whenever you turn on
the printer, it performs a cleaning cycle automatically. The printer
performs another cleaning cycle every 145 hours.
Under ordinary use, the EPI-4000's automatic cleaning cycles keep
the print head clean. If, however, you notice that the print quality is
declining, you can run the cleaning cycle to clean the print head.
Note: Your ink cartridge will run out prematurely if you run the
print head cleaning cycle often,
CAUTION:
If you have persistent problems with print quality,,
l
make sure you are using the right type of paper for
the EPI-4000. See the section on choosing paper in
Chapter 3.
Do not follow the steps in this section to run the
l
cleaning cycle when the display reads IL, the ink low
message. If you run a cleaning cycle when the display
reads IL, the display changes to 1E, the ink end
message, and you cannot use the printer until you
replace the ink cartridge.
