D. CLEANING THE PRINT HEAD
It may be necessary to clean the print head 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. Instead used the methods described below:
1. Open PTPublisher.
2. Go to Tools menu – Choose Printer Properties/Tools and
click Clean Print Head.
You will need an inkjet printable disc in the input bin 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.
