The text file being printed is shown on the terminal display, for example the ABCD file
as shown below.
NOTE:
•
The DISPLAY PRINTED TEXT command is available only when the printer is in
the
print
mode.
•
If special registers are used in the text file to be printed, their settings can be
reviewed (after a relevant command has been selected). The only exception is
the special register
universal date
where only coding characters are shown
instead of date in one of the formats available.
4.4.4. Servicing the Head
4.4.4.1. Defining Some Print Parameters with the Conveyor Travel Speed
In the main MENU select the SERVICE item and then the
CONVEYER MEASUREMENTS item.
Place two objects on the conveyor at a distance of one metre ( 1m ) one from the other
and make them move before the photodetector after the
CONVEYER MEASUREMENTS
. command has been selected. The terminal display
shows you real settings for the following parameters:
´
Conveyor travel speed shows a number of metres covered by the object within
a minute ( m/min ). The value can be used directly to make a setting and to
determine a setting for the print parameter
Cnv spd m/min
.
´
Number of pulses generated by the external encoder (in fact by the e
mechanical gears, if any) per unit distance ( pulses/m ). This is the so called
encoder constant. The value can be used directly to make a etting and to
determine a setting for the print parameter
Enc const p/m
.
NOTE:
•
In order to determine the encoder constant correctly, the print parameter
Generator must be set to SHAFT and the encoder axis must rotate while the
measurement is taken.
•
If the Generator parameter is set to GEN , the encoder constant is 0 (zero).
•
The distance between the objects can be smaller or greater than 1 metre. In
such a case the reading should be divided by the distance (x 1m.). For example,
if the distance is 0.2m, then the real encoder constant is five times greater than
that shown on the terminal.
4.4.4.2. Other Commands
The OTHERS item 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).
