Maintaining the Printer
❏ You performed the nozzle check and head cleaning 3 times and then waited for at least 12 hours without
printing, but print quality still did not improve.
Before running this feature, read the following instructions.
Important:
c
Make sure that there is enough ink in the ink tanks.
Visually check all ink tanks are at least a third full. Low ink levels during Power Cleaning could damage the
product.
Important:
c
An interval of 12 hours is required between each Power Cleaning.
Normally, a single Power Cleaning should resolve the print quality issue within 12 hours. Therefore, to avoid
unnecessary ink usage, you must wait 12 hours before you try it again.
Important:
c
Maintenance box replacement may be required.
Ink will be deposited to the maintenance box. If it becomes full, you must prepare and install a replacement
maintenance box to continue printing.
Note:
When the ink levels or the free space in the maintenance box are insufficient for Power Cleaning, you cannot run this
feature. Even in this case, the levels and the free space for printing may remain.
1. Select Maintenance on the printer's control panel.
2. Select Power Cleaning.
3. Follow the on-screen instructions to run the Power Cleaning feature.
Note:
If you cannot run this feature, solve the problems that are displayed on the screen. Next, follow this procedure from step
1 to run this feature again.
4. After running this feature, run the nozzle check to make sure the nozzles are not clogged.
For details on how to run the nozzle check, see the related information link below.
Important:
c
If print quality has not improved after running Power Cleaning, wait for at least 12 hours without printing, and
then print the nozzle check pattern again. Run Print Head Cleaning or Power Cleaning again depending on the
printed pattern. If quality still does not improve, contact Epson support.
Note:
You can also run power cleaning from the printer driver. See the related information link below for details.
