Cleaning the print head
Use this if faint or missing segments are detected in
the printed documents. This function cleans the
surface of the print head. There are two types of
function; one is to automatically detect clogged
nozzles and perform cleaning and another is to
perform head cleaning immediately after selecting the
level.
When selecting the cleaning level, you should
normally select Standard. If nozzles are clogged even
after performing Normal head cleaning several times,
perform Heavy cleaning. If the situation is not
improved even after performing Heavy, perform
Powerful Cleaning from the Administrator Menu.
