error.
Turn the printer off and on. Try making another print.
Check the image processor board-to-print engine connection.
Examine all the wiring harnesses for proper connection and
dress.
Press and hold the TEST button for 3 seconds to start a test
print. If a print is made, the print engine is functional. The
problem is probably with the image processor board.
If the error recurs, run diagnostics on the image processor
board as explained in the topic “Image processor
self-diagnostics” on page 6-31 at the end of this chapter.

configuration changed.
Ensure that the tray is properly installed.
Ensure that the tray-installed sensors operate properly and
are not damaged. Refer to the topic “Switch and interrupt
sensor checks” on page 9-12.

Hex Code 0D
Thermistor failure.
Ambient temperature sensor thermistor is shorted or open.
Check the wiring harnesses leading to the transfer roll sensor
board. Replace the transfer roll mark sensor board. Refer to
the topic “Calibrating the reflective sensors” on page 9-15 in
Chapter 9, “Checks and Adjustments.”

Hex Code 0E Thermal
head lift error.
Check for thermal head lift motion; ensure that the thermal
head lift motor operates correctly. The topic “Thermal head
motor check” on page 9-5 explains how to test the motor.
Ensure that the thermal head lift sensor operates properly and
is interrupted by the movement of the thermal head. The
topic “Switch and interrupt sensor checks” on page 9-12 tests
these sense switches. The sensor is located behind the left
end of the thermal head.

Thermistor is shorted or open. Check the wiring harnesses
leading to the thermal head. Replace the thermal head. Refer

roll empty.
Determine if the transfer roll is empty.
Determine if the transfer roll is installed and is properly seated
in the transfer roll holders.
Check the operation of the transfer roll sensors located under
the left and right ends of the supply roll. The switches are
actuated by the core end of the roll. Refer to the topic
“Calibrating the reflective sensors” on page 9-15 in Chapter 9,
“Checks and Adjustments.”
Ensure that the transfer roll is feeding properly past the
transfer roll sensors.
Check the operation of the transfer roll sensors. The transfer
roll mark check mode tests these reflective sensors. Ensure
that the white reflection plate below the sensors is clean.
Ensure that the transfer roll feeds properly and is not binding
or skewing. Ensure that the transfer roll feed-motor runs
smoothly.

Hex Code 12 Transfer
roll jam.
Check to see if the transfer roll is empty or binding. If not,
check the sensor and its wiring harness. Refer to the topic
“Switch and interrupt sensor checks” on page 9-12 in Chapter
9, “Checks and Adjustments.” Check the transfer roll mark
sensors and transfer roll motor for proper operation.
