[4] C/Bk laser driver
[5] BD circuit
[6] Laser relay PCB
MEMO:
The life of the laser scanner unit is dependent on the length of time during which the laser light is emitted.
To reduce the need for the detection of the BD signal associated with the emission of laser light, the machine also uses the FG signal for speed detection.
Scanner Motor-Related Error Code
The following error codes are associated with the scanner motor:
- E0100-0000 : BD error
Indicates that the interval of the BD signal at time of constant speed rotation has deviated from a specific interval for 1 sec or more.
- E0110-0000 : scanner motor error
Indicates that the scanner motor has failed to reach a specific revolution within 5 sec at start-up (BD control).
- E0110-0001 : scanner motor error
Indicates that the scanner motor has failed to reach a specific revolution within 5 sec at start-up (FG control).
