Installation Instructions
Revision B
•
When the “Flush Print Heads” screen is exited, regardless of valve state, the conditioner and waste
valves will be closed and the ink valve will be opened. If a flushing operation is taking place then it
will be stopped.
•
Power
switch:
o
When the ink IDS is powered up (or the power switch is toggled), the waste valve is closed.
o
When the conditioner IDS is powered up (or the power switch is toggled), the conditioner valve is
closed and the ink valve is opened.
o
The solenoid valves in the flushing system are of the normally closed type. If the conditioner IDS
is turned off then the ink and conditioner valves will be closed. If the ink ids is turned off the
waste valve will be closed.
•
Power outage: a power outage will behave exactly the same as toggling the power switch.
•
Broken line protection: This feature prevents the ink system from emptying an entire ink tank on the
floor after this type of incident. When the broken line has been repaired, toggling the power switch
or prime switch will reset this fault. The broken line protection feature is overridden during flushing
operations and when the waste valve is open.
•
The conditioner flushing sequence consists of two programming loops that open and close the waste
and conditioner valves. The first programming loop lasts two minutes and is not affected by the
number of cycles entered by the user. The second loop lasts twelve seconds for each cycle entered
by the user. At the end of the flushing cycle the print heads are purged, this takes about ten
seconds. When the cycle count is set to five, it will take 3 min. 10 sec. to flush the system with
conditioner.
•
The ink flushing sequence consists of two programming loops that open and close the waste and ink
valves. The first programming loop lasts fifty seconds and is not affected by the number of cycles
entered by the user. The second loop lasts twelve seconds for each cycle entered by the user. At
the end of the flushing cycle the print heads are purged, this takes about ten seconds. When the
cycle count is set to one, it will take 1 min. 12 sec. to flush the system with conditioner.
•
The amount of waste created will depend on the number of print heads being flushed and the
number of flushing cycles being run. As a reference, flushing four 18-dot print heads with ink and
the cycle count is set to one, 175ml of waste is produced. Flushing four 18-dot print heads with
conditioner and the cycle count is set to five, 425 ml of waste is produced.
