Ink States
Normal Operation
During Normal Operation, the Primary LED on top of the PM is illuminated green because there is at least 20%
or more ink left in the cartridge, and the smart chip on the cartridge is being read properly. Print is always
enabled in Normal Operation.
Ink Low
When there is less than 20% ink left in the cartridge, the lowest two LED’s on the ink supply gauge are yellow
and red from top to bottom alerting the user that Ink Out is imminent. Also, the Primary LED changes to red.
Print does not disable.
Ink Out
When
100% of all the ink has deposited from the cartridge
and into the ISM reservoir, the ink level begins
to drop. At a controlled point, the float in the reservoir drops low and triggers the Ink Out state. The lowest LED
on the ink gauge changes to flashing red as does the Primary LED. For best practices,
this is the appropriate
time to change the ink cartridge
. The time to refill the reservoir with a new cartridge is minimal. Print does
not disable.
Ink Error (Faults)
1. If the Ink Out state is ignored, a buffer is in place to allow for additional printing. Ten more milliliters of ink
are allowed. The time to consume this volume is variable based on application parameters. Once this 10ml
volume is consumed the system will change to an Ink Error state. The LED’s on the ink gauge will fast flash
as will the red primary LED. In addition, print will be disabled. It will take approximately 30 seconds to refill
the reservoir and lift the float switch up. At this point, print will be enabled.
2. If the ink cartridge is removed, then the operator will have 15 minutes to replace the cartridge. After this time is expired, and the cartridge has
not been replaced, then print will be disabled, and all LEDs will flash on the ISM interface.
3. If an incorrect cartridge type is inserted, then print will immediately be disabled and all LEDs will flash on the ISM interface.
NOTE:
Never mix ink types because they are not miscible. Irreversible internal damage will occur.
Ink Waste Collector Full
Upon filling the ink waste collector bottle, a float level detect raises inside the separator assembly. The feature
disables pumps inside the ISM until the waste bottle is emptied. By disabling the pumps, overflow is prevented
at the separator bottle. If the waste bottle is filled (waste float up) during a Clean / Prime, the cycle will
complete; however, subsequent cycles are not allowed.
