48 Troubleshooting and Maintenance
F. CLEANING THE PRINTHEAD
It may be necessary to clean the printhead nozzles if you notice
reduced print quality, missing colors or if you suspect an
cartridge nozzle has become slightly dried out or clogged.
Try the following solutions:
1. Secure
Cartridges. Make sure the corresponding cartridge
is snapped into place. Remove and reseat the cartridge to
make sure an air tight connection has been made. You
should hear a "click" when the cartridge is installed
properly.
2. Clean the Copper Contacts. Ink over spray can build up
inside the printer over time causing interrupted electrical
signals. Remove the printhead and clean the copper
contacts on the printhead carrier and the printhead.
3. Clean the Printhead.
DO NOT touch the printhead nozzles with a tissue or paper
towel. This can damage the nozzles! This may be different
that previous printers or even from what was printed in the
manual. Instead used the methods described below:
3A. Automatic Method (THIS WILL FIX MOST QUALITY
PROBLEMS!)
1. Open the PTStatus monitor.
2. Click
Clean Printhead on the Cartridge Utilities Tab
(second tab).
3. Follow the onscreen prompts. Make sure that "Purge
cartridge before clean print" is also checked.
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.
