1.5.1 Cleaning operation
If print output fades or blank lines appear on the output, check if the BJ head nozzles
are clogged by printing the nozzle check pattern. If clogged, clean the cartridge to
remove the stoppage.
With the printer powered on, hold down the
RESUME button and, after confirming one
beep, release the RESUME button . The cleaning operation will start. You can also clean
the print head from the computer using the printer driver utilities. ( See Page 3-5 )
After cleaning, check that the nozzles have recovered by printing the nozzle check
pattern again.
The cleaning operation cannot be performed when the scanner cartridge is installed.
1.5.2 Nozzle check pattern printing
With the printer powered on, hold down the RESUME button and, after confirming two
beeps, release the RESUME button . The nozzle check pattern printing will start, feeding
a sheet, which must be of A4 size, from the auto sheet feeder or manual paper feed
slot.
If print defects are detected in the test print, perform BJ cartridge cleaning. If five or
more cleaning operations fail to solve the problem, replace the BJ cartridge with a new
one.
If you start the nozzle check pattern with the scanner cartridge installed, the BJ
Cartridge Mis-installed Error will occur. (
See Page 3-2 ) In this case, if you replace the
scanner cartridge with the BJ cartridge, then the nozzle check pattern printing starts
automatically.
Use paper of A4 size or larger for the nozzle check pattern printing. If you
use smaller paper, the platen may be smeared with ink.
To abort the nozzle check pattern printing, press the POWER button . The
printer will switch off after ejecting the paper.
