(c) Set multimeter to read 0-5 V dc.
(d) Attach positive lead to TP5 on logic board.
(e) Attach negative lead to top end of capacitor C3.
CAUTION
Between dc return of logic and chassis of reader-printer, 105 V ac exists. Never use chassis as common when
making dc measurements on logic board. Erroneous readings will result and damage equipment.

Plug in power cord.
Switch reader-printer ON.
Place print length switch into LONG PRINT position.
Rotate long print potentiometer RI 00 to obtain maximum voltage
reading. This must be +3.75 V dc or greater.
Adjust R100 to read +2.50 to +2.75 V dc.
Place print length switch into SHORT PRINT position.
Rotate short print potentiometer RI 01 to obtain maximium voltage
reading. This must be +3.75 V dc or greater.
Adjust R101 to read +2.50 to +2.75 V dc.
If either long or short print potentiometers cannot be adjusted to produce minimum of
+3.75 V dc, replace appropriate sensor.
Step 2. Check temperature of thermal roller.
(a) If temperature is correct, proceed to step 3.
(b) Adjust if necessary (paragraph 3-20.2).
