In the
mode, the
START PRINT
command is followed by the application of high
voltage (
HV
) to the head.
HV
is needed to deflect a jet of ink drops. The actual
voltage value is displayed on the terminal with the
HV VALUE,PHOTO,SHAFT,AirP state
command. The command helps diagnose
some faults resulting from poor print quality and high voltage errors.
If the printer is not in the
mode, the
HV VALUE,PHOTO,SHAFT,AirP state
command results in displaying the figure
0.00
.
4.4.4.11. Defining Some Print Parameters by Measuring Conveyor Travel
Speed
In the main MENU select the following items in turn:
SERVICE
,
SERVICE COMMANDS
and
CONVEYER MEASUREMENTS
.
Place two objects on a factory conveyor at the distance of one meter (
1m
) from each
other and let them move in front of the photo detector after the
CONVEYER MEASUREMENTS
command has been selected. The results of
measurements of the following parameters are displayed on the terminal:
Travel speed (a number of metres/minute [
m/min
]) at which objects move in front
of the print head. The figure can be utilised directly or used to determine the
setting for the
Cnv spd m/min
print parameter,
Number of pulses generated by the external encoder per distance unit (pulses/
metre,
p/m
). It is called the encoder constant. The figure can be utilised directly
or used to determine the setting for the
Enc const p/m
print parameter.
NOTE:
•
In order to determine the encoder constant properly, the
Generator
parameter needs to be set to
SHAFT
and the encoder axle needs to rotate
during the measurement.
•
If
the
Generator
print parameter is set to
GEN
, the encoder constant is 0 (zero).
•
Objects can be placed on the conveyor at a distance smaller or greater than
1 m. Then the figure displayed on the terminal needs to be divided by the
multiple of 1 metre. For example, if the distance between the objects is 0.2 m,
then the resulting encoder constant is five times greater than that indicated on
the terminal.
4.4.4.12. Other Commands
The
OTHERS
option can also be selected from the
SERVICE
menu. It gives
the service person or a qualified person access to an extended list of service
commands (after the service password has been typed in).
4.4.5. Auxiliary
Commands
4.4.5.1. System
Data
In the main MENU select the
AUX. COMMANDS
item and then the
OPTIONS
item. The display shows the general information menu including the following data:
•
the printer’s serial number (the latter part of the number engraved on the front wall
between the doors) and a number of pixels meaning the maximum height of the
vertical row,
•
the settings for the printer’s various options and parameters,
•
the version numbers of control programs for each of the printer’s functional blocks.
