Colors are broken or
uneven
134
Troubleshooting
Cause
The BJC-70 driver may
not be selected.
The printer driver may not
be selecting color.
The Color BJ cartridge may
not be working properly.
The print head unit may
need cleaning.
You may have paused the
printer.
The print mode may be
inappropriate.
If you are generating a thin
line with a nonprimary
color, your software may
be telling the printer to
place a color every other
dot (white is in between).
Solution
Verify that you selected the
BJC-70 printer driver or
other compatible color
printer driver.
Check that you selected a
color option when you set up
the printer driver.
Run a test print to make sure
the Color BJ cartridge and ink
tanks are firing correctly.
If the ink tank is empty,
replace it.
Clean the print head;
see page 101 for details.
Make sure you did not set
the printer off-line during the
print job.
If you are printing high
density graphics on plain
paper, set the print mode to
Coated Paper in the Windows
driver. If you are using
MS-DOS, select Fine mode.
To correct this, choose cyan,
yellow, or magenta instead.
