AR-168N/168L OPERATIONAL DESCRIPTIONS 7 - 1

[7] OPERATIONAL DESCRIPTIONS

1. Outline of operation

The outline of operation is described referring to the basic configuration.

(Basic configuration)

(Outline of copy operation)

Setting conditions

1) Set copy conditions such as the copy quantity and the copy density

with the operation section, and press the COPY button. The infor-

mation on copy conditions is sent to the MCU.

Image scanning

2) When the COPY button is pressed, the scanner section starts

scanning of images.

The light from the copy lamp is reflected by the document and

passed through the lens to the CCD.

Photo signal/Electric signal conversion

3) The image is converted into electrical signals by the CCD circuit

and passed to the MCU.

Image process

4) The document image signal sent from the CCD circuit is processed

under the revised conditions and sent to the LSU (laser unit) as

print data.

Electric signal/Photo signal (laser beam) conversion

5) The LSU emits laser beams according to the print data.

(Electrical signals are converted into photo signals.)

6) The laser beams are radiated through the polygon mirror and vari-

ous lenses to the OPC drum.

Printing

7) Electrostatic latent images are formed on the OPC drum according

to the laser beams, and the latent images are developed to be visi-

ble images(toner images).

8) Meanwhile the paper is fed to the image transfer section in syn-

chronization with the image lead edge.

9) After the transfer of toner images onto the paper, the toner images

are fused to the paper by the fusing section. The copied paper is

discharged onto the exit tray.

(Outline of printer operation)

The print data sent from the PC are passed through the I/F and the

MCU to the LSU. The procedures after that are the same as above 5)

and later.

(Outline of scanner operation)

The scan data are passed through the MCU and the I/F to the PC

according to the conditions requested by the PC or set by the opera-

tions with the operation panel.
