Warning and Fault Messages
3.02 Over Speed (Print Go)
This indicates that the printer may have missed printing at least one pattern or is receiving false triggers
from the photocell.
When the Photocell Mode is set to Trigger, each print delay is started following the photocell trigger.
At the end of the delay a “print go” is issued to start printing. If the printer has not printed the last pattern
by this time, the warning is reported and the new pattern is not printed. In effect, this will mean that
alternate objects will NOT be printed on.
This warning may also occur when the Photocell mode is set to Enable or Off. In these modes the print
delay specifies the space between patterns. If the delay is set to a small value (less than 55) then this
error may occur.
The warning applies to the currently printing pattern - t is reset automatically when printing is restarted.
Possible cause
- The next object has arrived at the printhead before the last pattern is complete because:
1. The line speed is too fast.
2. The pattern is too long compared to the size of the objects to be printed on.
- The photocell is giving false triggers.
- The print delay is too small for Photocell Modes “Off” and “Enable”.
- The Photocell or Shaft Encoder modes have been altered and print started in Diagnostics rather
than by pressing the [start] key.
3.03 Ink Low
If the ink level sensor indicates that the ink reservoir is low then this warning is given. It is cleared
automatically when a sufficient amount of ink is added.
DO NOT put in more than one bottle. If the ink low condition is detected before the jet is started, then
the jet cannot be
started until the ink tank is replenished.
If the condition is detected while the jet is running, the jet will continue to run for several hours until the
ink is dangerously low, at which point a failure will occur (see Print Failure “2.06”).
3.04 Solvent Low
If the solvent level sensor indicates that the solvent reservoir is low then, this warning is given. It is
cleared automatically when a sufficient amount of solvent is added to the reservoir.
DO NOT put in more than one bottle. If the solvent low condition is detected before the jet is started,
then the jet cannot be started until the solvent tank is replenished.
If the condition is detected while the jet is running, the jet will continue to run regardless, but no attempt
will be made to add solvent.
3.05 Print Go / Remote Data
A “print go” has occurred and printing data has not been received from the remote interface.
3.06 Service Time
When the jet is started, the time remaining to the next service is checked. If it is zero or negative then
this warning is reported and the jet is started as normal.
The time to the next service can be set directly by the service engineer on the System Times menu in
Diagnostics.
This warning will be reported on every jet start up until the service time has been reset.
3.07 Print Head Cover Off
This warning is reported if the printhead cover is removed.
The supply to the EHT plates is switched off (by hardware) when the cover is removed.
WARNING: THERE IS A LINK WHICH, WHEN FITTED, DISABLES THIS AUTOMATIC SHUT OFF.
THEREFORE, THE PRESENCE OF THIS WARNING IS NOT A GUARANTEE THAT
THE EHT IS OFF.
