Running Power Cleaning

The Power Cleaning feature may improve print quality in the following cases.
❏ When most nozzles are clogged.
❏ When you have performed a nozzle check and head cleaning 3 times and waited for at least 12 hours without
printing, but print quality still did not improve.
Before running this feature, use the nozzle check feature to check if the nozzles are clogged, read the following
instructions, and then run Power Cleaning.
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.
