Chapter 8
Cause
The paper you are using
may not be supported by
the unit.
You may be printing on the
wrong side of the paper.
The print head nozzles
may be clogged.
BJ cartridge may be
installed incorrectly.
A BJ tank in the BC-21e
Color BJ Cartridge may be
empty.
The print head may be
worn out.
The resolution selected for
the MultiPASS printer driver
may be Fast (180 dpi).
Solution
Make sure you are using
the recommended paper
(see page A-1).
Some paper has a right side
for printing. If the print
quality is not as clear as you
would like it to be, try turning
the paper over and printing on
the other side.
Clean the print head (see
page 7-8); repeat cleaning
if necessary. If print quality is
not recovered after executing
the cleaning five times, replace
the BJ cartridge.
Make sure the BJ cartridge
and/or BJ tanks are installed
correctly.
Replace BJ tanks as necessary
(see page 7-16).
The BJ cartridge may need
to be replaced. Replace it with
a new one (see page 7-11).
Check your printer driver to
see what Print Mode you have
have selected. Changing the
Print Mode to Normal or
Best will improve the quality.
