ERROR 12e
Head Faild[xxxx]
(The details of [xxxx] are explained below this list.)

Cause:

• Abnormality of the Print head.
• Abnormality of the Driver of the Print head.

Solution:

1. Update F/W.
2. Initialize a parameter.
3. Disconnect and connect the FFC located between the Slider PCB and the SL-Relay PCB.
4. Replace the FFC located between the Slider PCB and the SL-Relay PCB.
5. Replace the Print Head with a new one.
6. Replace the Slider PCB with a new one.
7. Replace the SL-Relay PCB with a new one.

Details of ERROR 12e Head Failed [xxxx]
The relationships between [xxxx] (hexadecimal numeral) bit No. and the error contents are as below:

• bit0 [0001]
  Abnormal detection status of head signal (MN signal) (Slider PCB)
  1. Failure of head
  2. Failure of Slider PCB
• bit1 [0002]
  COM-OFF signal output status (Slider PCB)
  1. FFC breakage between SL-Relay PCB and Slider PCB
  2. Failure of head
  3. Failure of Slider PCB
• bit2 [0004]
  35V-1 Power supply voltage drop detection (Slider PCB)
  1. FFC breakage between SL-Relay PCB and Slider PCB
  2. Failure of Slider PCB
  3. Failure of SL-Relay PCB
• bit3 [0008]
  Driving wave shape circuit Current limit over (SL-Relay PCB)
  1. Failure of SL-Relay PCB (F2 blowout, COM circuit failure, etc.)
  2. Failure of Slider PCB
  3. Failure of head
  However, when bit6 or bit7 is “1” and an error ([3F88] or [3FC8] etc.) has occurred at startup, that error cause has priority.
• bit4 [0010]
  COM-OFF signal input status (SL-Relay PCB)
  1. FFC breakage between SL-Relay PCB and Slider PCB
  2. Failure of head
  3. Failure of Slider PCB
