Cleaning The Print Head - Epson Stylus Pro 4000 Reference Manual

Note:
If you turn on AUTO CLEANING from the control panel on the printer
even though Print has been selected, the Nozzle Check utility does
not only check the clogging nozzles, but also performs head cleaning
automatically. If you are using non-Epson special media, or if the
width of paper you are using is less than 210 mm, turn off AUTO
CLEANING from the control panel on the printer.
4. Follow the on-screen instructions to print a nozzle check
pattern.
5. If you find missing dots, clean the print head nozzles,
referring "Cleaning the print head" on page 184.

Cleaning the print head

If you find that the printed data is unexpectedly faint or dots in
the printed image are missing, you may be able to solve these
problems by cleaning the print head, which ensures that the
nozzles are delivering ink properly, by using the Head Cleaning
utility.
To use the Head Cleaning utility, follow these steps.
Note:
❏ Do not start Head Cleaning utility while printing is in progress;
otherwise, your printout may be marred.
❏ Use the Nozzle Check utility first to confirm that the print head
needs to be cleaned to save ink because this process consumes some
ink.
❏ When one ink out light is flashing or on, you cannot clean the print
head. Replace the appropriate ink cartridge first referring
"Replacing Ink Cartridges" on page 264.
1. Make sure that the printer is turned on and all ink lights are
off.
