2. Jet monitoring (Ink-Flow-Sensor active):
The ink jet monitoring provides highest operating reliability due to the additional
monitoring of the ink backflow. The full automatic monitoring turns off the ink jet as soon
as the ink backflow is interrupted. The nozzle seal will be closed automatically and head
impurities are therefore prevented.
By pressing the button <Ink-Flow-Sensor active> the jet monitoring is turned on or off.
With the two buttons <Ink on > and <Ink off > the ink delivery to the nozzle is turned
on or off.
This function can be generated also „remote-controlled“ by an electronic contact (see
also the informations under the following point „Extern ink on/off“).
During cleaning works at the print head it can be helpful (e.g. in case of a long umbilical)
that the ink delivery can be turned on/off externally. The JET2neo requires impulses for
the control.
This can be reached with a bridge between pin 9 and 14 and a switch contact
(pushbutton) at the pins 21 and 13 of the I/O-interface X4.
Example:
First impulse = switches off the ink delivery
Second impulse = switches on again the ink delivery
