Using the System
34
Shaft Encoder
The print must be stopped to change this option. Select ”On” if a shaft encoder is to be used, or “Off”
if it is not.
(See “Appendix 1: Installation and Setting Up” for shaft encoder setup).
Conduit Length
The jet must be stopped to set up this option. Select the appropriate conduit length for the printhead
fitted by using the left or right arrow keys.
Head Height
The jet must be stopped to set up this option. Pressure varies by 5 units for every metre above and
below the printer. You may change the value between -0.5 and +0.5 metres, however, printheads are
currently a maximum of 4 metres in length, so the maximum value here should be 4.0. Simply specify,
in terms of half or whole meters, how far above or below the printer the printhead is mounted. For
practical purposes, the measurement should be made from the space bar of the keyboard to the
printhead nozzle assembly. If the printhead is mounted below the printer, the value should be input
in the following format - X.Xm. If the printhead is mounted above the printer it is not necessary to place
a + in front of the value. The value may be entered simply as - X.Xm.
NOTE:
Care must be exercised with this option; poor printer performance will result if incorrectly
set.
This will automatically change the pressure reference from which the Solvent Add value
is calculated and shown on the MONITOR JET menu.
Print Head Code
This can only be entered if the jet is stopped. It will also need re-entering if a PCB or software is
replaced.
To be used when a new printhead has been fitted to the printer and/or when a reset to default has
occurred. The 14 digits are encoded as follows:
Ref. Modulation
Displays the current Reference Modulation. A new reference value may be added with a User Level
2 password.
Ink Selection
A choice between MEK, Ethanol or Pigmented.
Alarm
The jet must be stopped to change this option. When a printer warning or failure occurs, the system
activates an internal alarm tone (beeper) and an LED on the front panel. In a warning condition the
alarm tone is pulsed twice, whereas in a failure condition the alarm tone sounds continuously.
