Calibrating the Ribbon ID Sensor Board
The replacement Ribbon ID Sensor Board is calibrated by the factory; the procedure below is
not necessary in most cases. Because extreme precision is required, this procedure should
only be completed by a qualified electronics technician.
The printer will have difficulty reading the supply ribbon identification core if the Ribbon ID
Sensor is not calibrated correctly. It may print the first card in a series, but the second card
may stall in the printer and the on-line light will blink. If the on-line button is pressed, the
second card may print fine. (Note: This symptom is also identical to what occurs when the
wrong Ribbon Type is selected in the Printer Driver. Make sure the Ribbon Type selected in
the Printer Driver matches the ribbon installed in the printer.)
Caution: This device is electrostatic sensitive. It may be damaged if exposed to
static electrical discharges. (Discharges may be generated by various means, such as
walking on a carpeted floor.) Be sure to observe all established Electro-Static Discharge
(ESD) procedures while handling cables in or near the Circuit Board and Printhead
Assemblies. Always wear an appropriate personal grounding device, such as a wrist strap
with integral resistor, connected to an ESD ground to avoid potential damage. At a minimum,
make positive contact with the bare metal chassis of the printer with the hand before
proceeding with the procedure.
