Lines At Swath Boundary - Canon Colorado 1650 Operation Manual

Lines at swath boundary

Introduction
Swath boundary. Two adjoining swaths/passes of the printhead must be positioned without
overlap (dark lines), or gap (white lines ).
Problem description
OD lines occur at the
swath boundary.
OD of the lines usually
varies over the print
(from left to right or
from line to line).
May be accompanied
by OD/Gloss differen-
ces between swaths
(these are uniform
within the swath), or
even a generally re-
duced OD in case of a
fixed, large paper step
error.
Very sharp line(s), no
OD variation over
print and only for a
single mono-color
(and its corresponding
mixed colors)?
For some (fast) print
mode-medium combi-
nations gloss/OD
swath boundary lines
will always be
present.
Follow the procedure below. You can stop at any time in the procedure when the problem is
solved.
Usually worse during
st
1 meter.
The way it varies is
useful in determining
the cause of the prob-
lem. If the suggested
solutions do not help.
Independent from pa-
per step errors,
though paper step op-
timization may reduce
visibility.
Cause
This is caused by a
nozzle failure at swath
boundary and not due
to paper step.
Roll core gear is dam-
aged or warn out. Or-
der new and replace.
