6.3 Various Controls
6.3.1 Controlling the Laser Activation Timing
6.3.1.1 Generating the Sync Signal
0015-4425
iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
The BD signal used to synchronize the video signal in laser scanning direction is generated by the BD PCB with reference to the laser beam reflected by the BD
mirror mounted on the laser beam optical path. The CCD/AP PCB reads the image signal from the CCD, and sends it to the controller block. The controller block,
in response, executes image processing, and sends the result as a video signal to the laser driver PCB by way of the video PCB and as the laser intensity control
signal to the laser unit.
6.3.1.2 Flow of the Sync Signal
0015-4426
iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
[1] BD signal (upon detection of laser light, '0').
[2] phase matching is executed with reference to the printer, and the synch signal is generated.
[3] reads the image data from the image memory in keeping with the printer sync signal.
[4] video signal
[5] converts the 2-pixel parallel signal into a signal-pixel serial signal.
[6] laser drive signal (drives the laser unit according to the video signal).
F-6-3
ERROR DODE:
E100
Issued when the BD signal is not detected within a specific period of time after the laser has been turned on.
