68 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 print head 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 print head can be caused by non use
of the printer for extended periods of time. Follow these guidelines:
• Always keep the LX900e plugged in and turned on. The printer
will do periodic maintenance to make sure the
nozzles do not clog.
• Never store a used print head outside of the printer. The nozzles
will dry out with exposure to air. If you must store a print head
outside of the printer, place full or empty
cartridges in the print head and put the entire print head 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 Print Head/Cartridge. The cartridge may be empty or
defective. The print head nozzle for one color could be clogged.
The fastest way to diagnose a quality problem is to have backup
print heads and cartridges available for comparison testing. If
one color is missing, replace that color cartridge(s). Next try
replacing the print head.
