Hue changes.
The nozzles on the BJ cartridge print head may be clogged.
❑
Print the nozzle check to check the BJ cartridge print head (see page 6-13).
Perform the BJ cartridge print head cleaning procedure if necessary (see
page 6-14).
A BJ tank may be empty.
❑
Replace empty BJ tanks as necessary (see page 6-22).
Blue looks like purple.
Blue prints out as purple because of the difference in color technology used by
the screen and the MultiPASS; the screen uses RGB (Red, Green, Blue) color and
the MultiPASS uses CMYK (Cyan, Magenta, Yellow, Black) color. Due to the
technology differences, when cyan and magenta are mixed together, blue prints
dark blue or purple compared to the screen.
❑
If you selected Use ColorSync Color Matching in the Color dialog, make sure
that you have selected an appropriate Printer Profile for the media type you
are using (see page 2-11 in the MultiPASS Desktop Manager Software Guide). If
you are not using screen matching, decreasing the amount of magenta by 30%
produces a royal blue. If the output is not satisfactory, try turning off the Use
ColorSync Color Matching option.
❑
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.
Color images are missing some detail.
The print mode may be wrong.
❑
Check your print mode setting in the Print dialog (see see page 2-9).
