Maintenance and Troubleshooting
4.
Preventing clogged nozzles.
Clogged nozzles on the print-
head can be caused by non use of the printer for extended
periods of time. Follow these guidelines:
• Always keep the 4100 plugged in and turned on. The
printer will do periodic maintenance to make sure the
nozzles do not clog.
•
Never store a used printhead outside of the printer. The
nozzles will dry out with exposure to air. If you must store
a printhead outside of the printer, place full or empty
cartridges in the printhead and put the entire printhead
and cartridges in a sealed plastic bag.
•
Use the printer regularly!
5.
Quality Setting.
Change your quality setting. The lowest
(and fastest printing) quality may not be sufficient for
many photos or graphics. The highest quality setting may
cause ink to bleed on certain graphics in combination with
certain disc types. Increasing the quality increases print
time because the printer makes more passes over the
media.
6.
Replace Printhead/Cartridge.
The cartridge may be empty
or defective. The printhead nozzle for one color could be
clogged. The fastest way to diagnose a quality problem is
to have backup printheads and cartridges available for
comparison testing. If one color is missing, replace that
color cartridge(s). Next try replacing the print head.
7.
Defective Printhead/Cartridge Replacement Procedure.
If
you think your cartridge/printhead is defective, please
contact tech support to arrange for a replacement. Tech
support may ask you to perform troubleshooting before
sending a replacement cartridge or printhead.
Notes on Ink/Printhead Replacement
• All replacements for defective cartridges or printheads
must be processed through Tech Support.
•
To receive replacement cartridges, you may be required to
send in your defective cartridges/printhead.
•
Tech Support will perform the cleaning procedures and
tests mentioned above on all cartridges/printheads
received.
•
Tech Support will not replace cartridges with less than
50% ink remaining.
