Print Head Maintenance
Do print head maintenance if white lines appear in
your print outs, if the printouts are dirty, or if you any
have problems with the printed results.
Maintenance Operations
You can perform the following printer maintenance
functions for maintaining the print head in good
condition to ensure the best print quality. Carry out
appropriate maintenance depending on the print
results and situation.
Automatically detecting clogged
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.
❏ Ink is consumed when performing automatic
cleaning.
You can set the following items on the Printer Setup
menu and the Maintenance menu.

Auto Nozzle Check
When this is set to On, the status of the nozzles is
checked at the following times. 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
c
Important:
Even if Auto Cleaning Setting from Auto Nozzle
Check is set to Off, an auto nozzle check is always
performed at the following times.
❏ After initial ink charging
An auto nozzle check is performed after ink
charging to check the status of the nozzles. If
clogged nozzles are detected, auto cleaning is
performed once.
❏ Before changing the type of black ink
Since black inks cannot be changed correctly
if nozzles are clogged, an auto nozzle check is
performed. If nozzles are clogged, auto
cleaning is performed (up to three times) until
the nozzles are cleared regardless of the Auto
Cleaning Times setting.
❏ An auto nozzle check is done after the Paper
Jam message is displayed on the control
panel's screen and the printer is turned back
on because a paper jam may cause the nozzles
to clog. If the nozzles are clogged, Auto
Cleaning is done just once.
Timer Cleaning
After the set time has passed from the end of the
previous print job, the status of the nozzle is checked
when the following operations are performed. If
clogged nozzles are detected, cleaning is done
automatically.
❏ The printer is turned on
❏ The printer returns from sleep mode
Printless Nozzle Check
If you execute this, the status of the nozzles is checked
and the results of the clogged nozzle detection are
displayed on the control panel. When clogged nozzles
are detected, if you then press the [ button,
cleaning is done automatically.
