Troubleshooting and Maintenance

3. Make sure the "purge cartridges before clean" box is
checked. Follow the onscreen prompts. You will need a
sheet of paper for this process.
You may need to repeat this process up to 4 times depending
on how clogged the printhead is. Only repeat the procedure if
you start to see improvement after each clean print.
During this process the printer will make several loud whirring
noises. This is normal! This is the sound of a pump forcing ink
through the nozzles. If you do not hear this sound, the clean
purge print did not complete successfully. Try again.
4. Preventing clogged nozzles
Clogged nozzles on the printhead can be caused by non use of
the printer for extended periods of time. Follow these
guidelines:

Always keep the RX900 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 label stock. Increasing the quality increases print
time because the printer makes more passes over the
media.
6. Backup 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.
