Troubleshooting
Cause
Print head nozzles may be
clogged with dust.
An ink tank may be
empty.
Blue prints out as purple
because of the difference in
color technology used by
the screen and printer; the
screen uses RGB color and
the BJC-70 uses CYMK
color. Due to the technology
differences, when cyan and
magenta are mixed together,
blue prints dark blue or
purple compared to the
screen.
Check to see if your
Windows printer driver is
set to Plain Paper, Color
mode, and Pattern.
Solution
Clean the print head; see
page 101 for details.
Check the ink tanks. If
an ink tank is empty, replace
it with a new one.
Within the Windows printer
driver, selecting screen
matching will result in
a lighter blue. If you are not
using screen matching,
decreasing the amount of
magenta by 30% produces a
royal blue.
If you are just looking for a
nice blue color, try cyan. It
prints beautifully and fast
and is available in almost all
applications that support
color.
If so, change the Media Type
setting from Plain Paper to
Coated Paper.
