2.5 Control
This section describes the main controls performed by this printer.
2.5.1 Hardware for Control
VSYNC
VSYNC is a falling edge signal generated when the protrusion on the right edge of the
transfer belt passes through the VSYNC Sensor (a photo-interrupter sensor). By
detecting the VSYNC signals, the engine measures the rotation period and rotation
number of the belt as references for the timing of image formation and the unit life.
TEMPERATURE AND HUMIDITY SENSOR
Detects the temperature and humidity in the printer to optimize the transfer biases at
the primary transfer and secondary transfer.
PATCH SENSOR
A reflective photo sensor that detects the patch density created on the transfer belt to
perform the image-optimization control (process control).
This sensor emits an infrared light to the patch and receives the reflected ray from it to
detect the density.
NVM
A nonvolatile memory for storing engine information. The NVM is mounted on the
NVM board connected to the engine controller board.
