The mode <Interval operation> enables the input of start- and end times when the Leibinger JET One turns on or off automatically (e.g. 10.20 pm, the device turns on / 10.40 pm, the device turns off). to circulate the ink.

This function prevents that the ink dries up or sediments as well as the jamming of the nozzle if the printer is turned off for a longer time.

As standard the interval operation is carried out without viscosity control. In case of need the viscosity control can be also activated for the interval operation.

Attention! The viscosity control should be only activated for special operating conditions of the JET One or after consultation with the LEIBINGER-service department.

You should set an interval time of at least 20 minutes.

 Press on the register card <Interval> (1) to select the functional area.

 Press on the display window <Interval on> (2). A setting block (4) opens.

 Select the desired time by scrolling the hour and minute block. The setting block is closed by clicking on the block again or on thes display window <Interval on> and the time is saved.

 Now carry out the settings in the display window <Interval off> (3) accordingly.

 Now activate if necessary the viscosity control by clicking on the control box (5). An activated control is displayed by a  in the control box.

7.2.3.1.4 Interfaces (Encoder interface)

Under the register card < Interfaces> you can set the interface for the incremental encoder and you can also switch on or off the bounce time delay. The bounce time delay is required for working with external jobs.

How can you explain the terms „bounce time“ and „bounce time delay“?

Bounce time:

Describes the period which a signal requires after an input has been switched to reach a defined status (0 or 1) again.

JET One Release R1.01 en Bounce time delay:

Describes a predefined safety time. That means if an input is switched, the signal will be only valid after this safety time.

At the Leibinger JET One you can switch on or off this safety time.

With the button <Hydraulic settings> (1) the menu „Hydraulic settings“ will be displayed.

In this menu the basic hydraulic parameters of the device are set. The menu is divided into 2 function areas for better clarity.

Changing the preset parameters can cause serious malfunctions!

This work must only be carried out by trained personnel or by Leibinger service technicians!
