Backflushing a Nozzle
Missing dots in messages can be caused by contaminents lodged in
printhead nozzles, or improperly seated valve mechanisms. Backflushing a
printhead nozzle or valve can remove contaminates or reseat the valve.
Note: This procedure requires the use of a Backflush Kit. To order see the
"Parts List."
1) From a print sample determine which nozzle or valve you will need to
2) Unplug the controller and the printhead power supply.
