ISM Features
Recirculation
This feature can only be controlled locally at the print head as the orifice shipping cap must
be aligned properly and securely mounted in place. Recirculation is a unique and valuable
feature as channel priming time is reduced at initial setup, or channel loss due to significant
vibration and / or high-impact events. The feature can be activated by pressing and holding
the
Recirculation
button on the top of the ISM for 10 seconds; its LED turns ON as shown.
During this time it is critical to have the orifice shipping cap installed and properly aligned
with the supplied front-plate grooves. The user can choose when to disengage the feature
by manually pressing the button again, or it will time-out after 15 minutes. After removing
the ship cap and swabbing the orifice plate, the prime feature should only be needed 1-2
times, significantly reducing the amount of ink usage. In addition, the expectation should be
for significant channel recovery.
Clean / Prime
The print system also incorporates a Cleaning System to remove debris from the orifice
plate. A small vacuum channel has been designed into the bottom of the nozzle plate.
During a cleaning cycle, a small amount of ink is pulsed through the orifices. When the cleaning cycle is activated, the vacuum pump turns ON, as well as its
LED (shown OFF), shortly after, the ink pump pulses to control the flow out of the nozzle plate, and then the vacuum pump continues to run for 45 seconds to
ensure ink / waste residue is pulled to the waste collection bottle located at the rear of the ISM. A Clean cycle can be manually initiated by pushing the
Clean /
Prime
button located on the rear of the ISM, or it can also be programmed to run at specified times by using the control software.
All Channel Print
The functionality to check for 100% print from the print head is available locally at the print head. This function can be performed by momentarily pressing the
All Channel Print
button on the rear of the print head while passing a substrate in front of it in a horizontal direction.
PM Digital Level
A digital level indication is provided by three LEDs located on the top rear of the enclosure. The print head is considered level, as indicated by a central green
LED, when the PM is /- 1.5° front-to-back, level to the horizon. The digital level is factory calibrated.
Ink Cartridge Status Gauge
Ink volume in any given cartridge is tracked down to the milliliter. Status is both read and written to the cartridge. If the cartridge is moved to
another print head, then the correct ink volume is maintained with the cartridge. In addition, there are five LED divisions on the rear of the ISM.
Each division representing 20% ink volume.
Waste Bottle Status
During normal operation the waste bottle status light will be green; indicating the waste bottle is not full. When the ink waste level rises to a point
where it lifts the float UP in the waste module, this LED will turn red. The waste ink will then need to be removed and emptied according to local
laws and regulations. When the waste bottle is removed, the float switch will drop DOWN, and the LED will change to green.
