(b-4) "Operation signal"
1 The "operation signal" is an instruction signal that automatically causes operations
to be performed up to an ink jet.
If the "operation signal" is turned on during ink stop processing, it will be ignored.
2
Turn on the "operation signal" after the lapse of 30 seconds or more after turning
3
on the power supply of the IJ printer.
After making sure that "Fault" has been cleared, input the signal.
The time from turning on the "operation signal" till a print enable status is about 2
minutes.
(b-5) "Stop signal"
1 After making sure that that the IJ printer is put into a pause by turning on the "stop
signal", turn off the power supply.
The time from turning on the "stop signal" till a pause status is about 3 minutes.
2 The time t from an input of "stop signal" till a change of status is 100 ms or less.

(Cautions)
(1) When using key inputs, you must check each input. However, when inputting
external signals, the equipment executes processing in accordance with
instructions of these signals. In particular, the "operation" (operation signal)
instructs an ink jet.
So take extreme care in handling this signal.
(2) When the confirmation window appears, every remote signal input is
invalidated.
After closing the confirmation window, input each signal once again.
When Line monitor is displayed, all remote operation signals will be disabled.
(3) When each of the touch screen setup screen and the circulation control screens
appears, every remote operation signal input is invalidated. After displaying a
different screen, input each signal once again.
(4) When the conveyor is stopped during printing by using the rotary encoder, the
remote operation signal is valid.
(5) In the case of inputting a stop signal while the fault window is open, the ink
stops with the window remaining open.
