Printing Jobs on the Gerber CAT | UV

Automatic printer operations

There are some behavioral characteristics of the Gerber CAT|UV that you should be aware of
before printing a job.

UV lamp warm-up

The lamps are turned on only before starting a job. The UV bulbs require a short warm-up cycle
if they are not at the proper operating temperature. When the lamps are in the warm-up phase
the progress bar will appear on the screen estimating the amount of time required to warm the
lamps to the proper operating temperature.
Warm Up - <job name>
70%
When they have reached their operating temperature, the cooling fans automatically turn on to
maintain the proper temperature.
NOTE: The UV lamps do not require a cool down phase before re-striking.

Sleep/Idle mode

After 10 minutes of idle time
When the Gerber CAT|UV is idle for 10 minutes it will automatically go into idle mode. When
in idle mode, the UV lamps, vacuum blowers, and roll-to-roll fans turn off and the gantry rises
to its home position. During the first two hours of idle mode, the printer will maintain proper
printhead temperature and spit ink every 5 minutes to ensure that the printer is prepared to
print.
After two hours of idle time
When the printer has been idle for two hours it goes into sleep mode and the printhead heaters
automatically turn off and the printer ceases to spit ink. The Clean Head LED blinks to indicate
that you should perform the Clean Heads procedure before printing (see page 78).
Every thirty minutes when the printer is in sleep mode the Gerber CAT|UV automatically
reestablishes vacuum pressure to ensure that no excess ink drips from the printheads.

Automatic spitting to clear the nozzles

Every five minutes while the printer is active, the Gerber CAT|UV clears the printhead nozzles
by spitting a small amount of ink in the waste ink tray. If the printer is printing when spitting is
scheduled, it pauses at the end of a swipe and moves the carriage to the spitting location and
clears the printheads. After spitting, printing resumes.
When the printer has entered idle mode, it continues to spit for the first two hours. After two
hours it ceases to spit ink and you must run the Clean Heads procedure upon resuming
printing operations.
