Fatal Error Code 0F: APTC Error
This error occurs when the Home Position (HP) of the Automatic Paper
Thickness Control (APTC) mechanism is not detected.
This error is caused by a malfunction of either the APTC HP sensor
circuit, the APTC motor, or the driver circuit on the ROM Board.
Check the following in the order below, testing functionality at each
step. If the APTC motor has malfunctioned, be sure to check the motor
driver circuit on the ROM Board before replacing the motor.
1. Check connectors CNSEN1 and CNSEN2 on the ROM BOARD.
See Figure 4-10 on page 137.
2. Check and replace the APTC HP UNIT
3. Check both the APTC motor,
(p.137), and replace either or both as necessary.
Fatal Error Code 11: Ribbon Feed Driver Error
The Mechanism Control ASIC has detected a malfunction of the Ribbon
Feed (RF) motor, RF motor driver element (HIC2: HIC3), or both.
A single phase of the Ribbon Feed (RF) motor was energized for longer

Check for a ribbon jam, and replace the ribbon cartridge if necessary. If
the ribbon cartridge is not jammed, this error may be the result of a
malfunction of the RF sensor circuit, RF motor or RF motor driver
circuit.
Check the following in the order below, testing for functionality at each
step after step 3. Be sure to check both the motor driver on the ROM
Board and the RF motor before replacing either. It may be necessary to
replace both.
1. Check the RF Unit connectors CNRMS and CNRFS on the Sensor
Board. Also check the RF Motor connector on the Sensor Board. See
Figure 4-13 on page
2. On the ROM Board, check connector CNSEN1 (includes the RJM
signal input) and CNSEN2 (includes the drive signal output). See
