Resolving the Unknown Ribbon Type Error Message
Symptom: The Printer is unable to determine the type of ribbon installed.
Step Procedure
1 Verify the ribbon type.
a. Ensure that the print ribbon installed in the Printer is an HDP ribbon. (Note:
Although similar in appearance, a DTC ribbon installed in an HDP Printer
will produce an Unknown Ribbon Type error message.)
2 Test the Ribbon Sensor.
a. Remove the back cover and locate the connector labeled J65 on the main
Board.
b. Check the voltage for each of the five (5) Ribbon Sensors (140404 and
140407) at their connection to the main Board.
c. Use a Multimeter to ground the negative lead to the chassis and put the
positive lead on pins 3, 5, 7, 9 and 11 of J65 on the main Board.
d. Place a RibbonTraq™ mark over the Ribbon Sensor. (Note: The voltage
should be less than 1 VDC.)
e. Remove the RibbonTraq mark from the Ribbon Sensor. (Note: The
voltage should be greater than 3.5 VDC.)
f. Replace the Sensor if the voltages are incorrect.

Step Procedure
1
Press the Resume button to retry.
2 If the Headlift does not rotate, check the Headlift Motor to ensure that it is
running.
3 If the Headlift Motor is not running, replace the Headlift Motor as described in
the Replacing the Headlift Motor Assembly (D840980)
procedure in Section 5,
page 292.
4 If the head cycles but does not stop at the position every time, check the
Headlift Sensor as described in Sensor Testing
in Section 7, page 440.
5 If the Headlift Sensor is failing, replace it. See the Replacing the Headlift
Sensor Assembly procedure (D804983) in Section 5, page 294.
