Laser Pulse Times

: 49.2 µs

Laser Output Power : 0.73 mW

CAUTION

This laser printer is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH standard. This means that

this machine does not produce a hazardous laser radiation. The use of controls, adjustments or performance of procedures other

than those specified herein may result in hazardous radiation exposure.

This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved on the eyes retina, there is

danger of spot damage to the retina.

The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.

1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not an individual part.

2) Do not look into the machine with the main switch turned on after removing the toner/developer unit and drum cartridge.

3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and installing

the optical system.

FO-4700U FO-47UC 10. IMAGE TRANSFER 11-2. Fusing Temperature Control Circuit 10-1. Overview The Thermistor (TH1) detects the surface temperature of the Upper Fusing Roller and inputs that analog voltage into IC2-78. Corresponding to this data, the Heater Lamp ON/OFF signal is output from IC2-55, causing the Heater Lamp (H1) to turn ON or OFF to control the fusing temperature.

FO-4700U FO-47UC 12. PRINT SEQUENCE Printing is carried out following communication between the engine and controller that determines the timing to be used. A general outline of the printing sequence is described below. Controller Engine /PRINT Initiates the printing command. Prepares for printing - Print head -Feeds a sheet of paper, etc. Receives the vertical direction synchronizing signal. /TOD Receives the mainscanning direction synchronizing signal. /HSYNC Sends video data for one scan.
