RECORDING SECTION

At the LASER/scanner section, the image is drawn on the photosensitive

drum by the LASER beam. The image at this stage is not yet visible to the

human eye. In the printing process section, toner is attached to this invisi-

ble image on the photosensitive drum to change it to a visible image, and

the toner is transferred to and fixed on the recording paper, which is then

eject.

Next, let’s describe each of these components in a little more detail.

Video Control Section/Printer Engine Control Section

At the video control section, the image data that has undergone image pro-

cessing is converted to video signals. The video control section then

checks the state of the printer engine by handling the signals with the

printer engine control section, and then instructs printing, after which it

sends the video signals.

The printer engine control section generates the LASER drive signals

based upon the received video signals, and sends the LASER drive signals

to the LASER/scanner section. These signals that are handled between the

video control section and printer engine control section are called “video

interface signals.”
