2.10.4 Sensor Adjustments
Through the following procedure, it is possible to adjust the sensitivity of
the three sensors in the B-419 printer from your PC via the RS-232C
interface. The three sensors are the reflective (black mark) sensor, the
transmissive (feed gap) sensor, and the paper end sensor.
• Setup
To begin the sensor adjustment operation, you will need to turn on the
power of the B-419 printer (do not hold the feed key this time). Connect
the printer to the PC with the RS-232C cable. Select the TPCL-LE mode
for the printer issue mode. Then set the communications parameters as
follows:
19200 bps, None parity
• Start
1.
From the Install Program for B-419 main menu, select Options (O)
then select Sensor Adjustment (S) as shown in the figure below.
2.
After highlighting and clicking on Sensor Adjustment (S) from the
above display, the screen display will change to the Sensor
Adjustment menu. Click on the
Read A/D
button. The screen will
now display the current sensor output values.
NOTES:
1. These sensors have been
factory set so it is not
advisable for you to make
these adjustments unless
you are having a problem
with the printer.
2. If the sensor adjustment is
required, be sure to follow
the procedure as described.
Failure to do this may
cause a malfunction of the
printer.
3. Do not turn on the printer
with the media being set in
the printer. Doing so
causes the printer to feed
the media automatically,
and you cannot adjust the
sensor. To inactivate the
auto feed function during
the sensor adjustment, turn
the printer power on with
no media or with the media
cover open, and then click
on
Read A/D
button.
