Phaser 540 Color Printer
A single, wide, light horizontal
band appears in one place on
the page
or the entire image
is faded.
The imaging unit was exposed too
long to light.
Wait overnight and print the test print. If
print quality hasn’t changed, replace the
imaging unit.
Large light spot(s) appears
randomly in the print.
Fingerprint(s): someone has touched
the underside of the imaging unit.
Artifact(s) fades after several prints.
On the test print, each color
“bleeds” into the color band
below it (the most visible is
magenta in the yellow band).
The cleaning blade inside the imaging
unit is not cleaning an internal belt.
Replace the imaging unit.
