Operator Menu
The Operator menu has six submenus: Maintenance, Test Prints, Print Parameters,
Units, Set Clock, and About Printer. The details of these submenus and how to access
them are provided below.
Maintenance
The Maintenance Menu consists of various commands that support maintenance
activities for the printer. The commands are:
TURN ON/OFF UV LAMPS
Turn the UV lamps ON if you want them to start warming up before you start a
print job. This reduces the wait time between issuing a print job and the time it
actually starts. Turn the UV lamps OFF if you know that you will not issue more
print jobs (for example, at the end of the day). This speed up the process of cooling
down the lamps.
HIGH PURGE NOZZLES
This is used to clear contaminants out of the nozzles. Contaminants can be either
environmental particles or dried ink. During a High Purge, the ink reservoirs are
pressurized to 15 PSI for 300 milliseconds.
LONG PURGE NOZZLES
This is used primarily to clear the printheads or clear air from the inklines. A Long
Purge pressurizes the ink reservoirs to 5 PSI for 1.0 seconds.
RECOVERY PURGE NOZZLES
This command is used as a troubleshooting tool to restore a printhead that will not
respond to a high purge. A Recovery Purge pressurizes the ink reservoirs to 15 PSI
for 1.0 seconds.
BLOT HEADS
Blotting heads is the process of pressing the print heads into an absorbent cloth.
This is necessary to remove any ink which may have accumulated on the print head
nozzle plates. Note that blotting occurs as part of the normal pre-print
maintenance, so it is not generally necessary to perform a manual blot.
SPIT HEADS
This command is used to evaluate the condition of the printheads. When it is
initiated the carriage moves to the blotting station. All printheads then fire into the
blot cloth. The carriage then returns to its previous state of operation. The operator
can then observe the ink patterns created on the blot cloth from the spit. If the
patterns are not forming clean lines of equal length, it can be an indication of
blocked nozzles.
