maintenance if white lines appear in your printouts or
if you notice the print quality has declined.

ensure the best print quality. Carry out appropriate
maintenance depending on the print results and

nozzles
The printer has functions that allow it to
automatically detect the position of clogged nozzles in
the print head and perform cleaning without having
to print a nozzle check pattern.
Note:
❏ This function does not guarantee 100% detection
of clogged nozzles.
❏ A small amount of ink is consumed when
detecting clogged nozzles.

Auto Nozzle Check

checked at the following times and clogged nozzles are
detected. When clogged nozzles are detected, cleaning
is performed automatically the number of times set on
the control panel.
❏ When printing starts (periodically or every job)
❏ Before and after head cleaning

An error occurs even if this is done in environments
outside of the specified range for the printer, such as
when the operating temperature is less than 10°C.

Printless Nozzle Check
Perform this to check the status of the nozzles, and the
results of clogging detection are displayed on the
control panel. When clogged nozzles are detected,
cleaning starts automatically when you select OK.
An error occurs even if this is done in environments
outside of the specified range for the printer, such as
when the operating temperature is less than 10°C. If
you want to check for nozzle clogs while out of the
range for the operating temperature, print a check
pattern to check.

Checking for clogged nozzles using
the printed check pattern
We recommend printing a nozzle check pattern and
performing a visual inspection before printing when
the printer has not been used for an extended period
or when printing important print jobs. Visually
inspect the printed pattern and clean the print head if
you notice faint or missing areas.
