Paper Feeding Problems

Problem
Paper does not load
Chapter 10
Cause
The print settings may not
be the best for the images
you are printing.
The print nozzles may be
clogged with dust.
A BJ 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 (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.
Check to see if your MultiPASS
printer driver is set to Plain
Paper, Color Mode, and
Halftoning=Pattern.
Cause
The sheet feeder may contain
too many sheets.
Paper may not be inserted
correctly.
Solution
If you are printing high
density color graphics on
plain paper, change the Media
Type setting from Plain Paper
to Coated Paper.
Be sure to experiment with
different settings and different
types of paper.
Clean the print head. See
page 9-8.
Replace empty BJ tanks as
needed. See page 9-16.
Within the MultiPASS printer
driver, selecting Match (screen
match) in the Color Adjustment
dialog box of the Custom Setting
window 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.
Solution
Make sure the stack of paper
in the sheet feeder does not
exceed the limit mark.
Make sure the stack of paper
is inserted into the sheet feeder,
and the paper guide is adjusted
correctly.
