Intermec EasyCoder 201 II – Technical Manual
LABEL-TAKEN SENSOR, cont'd.
❑ The intensity of the light emitter in the label-taken sensor can be
adjusted by means of a strap on P-14 on the CPU board.
• Strap fitted = Higher intensity
• Strap removed = Lower intensity
❑ The sensitivity of the receiver in the label-taken sensor can be
adjusted by means of a potentiometer situated behind a cover
plate on the printer's rear plate, as described in the chapter
“Electronics; Potentiometers” later in this manual.
❑ You can adjust the potentiometer randomly and check if it is
working properly by trying to print a label without removing the
previous one. Also check that you can print a label when there
is no label left above the LTS. Use the trial-and-error method
until the LTS works properly. If a proper adjustment cannot be
achieved by means of the potentiometer, fit or remove the strap
on P-14 (see above).
❑ Another way is to make a simple Intermec Fingerprint program
that checks the printer's status using the PRSTAT function (also
see Intermec Fingerprint manuals).
Here is an example on how such a program can be made:
10 BREAK 1,88
20 BREAK 1 ON
30 ON BREAK 1 GOSUB 1000
40 FORMFEED
50 IF (PRSTAT AND 2) THEN BEEP
60 GOTO 50
70 END
1000 BREAK 1 OFF
1010 GOTO 70
RUN
You can break this program by transmitting the character X
(ASCII 88 decimal) on the standard interface "uart1:".
• Leave the label, ticket etc. in the outfeed slot.
• The sensor is properly adjusted when the printer beeps
continuously. Turn the potentiometer screw a quarter of a
turn in each direction. The beeping should not stop.
• Remove the label and the beeping should cease at once.
• If necessary, adjust the potentiometer until the label-taken
sensor works as described above.
• When adjusting the potentiometer, always create a safety-
margin by turning the adjustment screw a quarter of a turn
further after the beeper has started or ceased to sound.
❑ Close the cover.
