For this reason, laser radiation emitted inside this machine is hermetically sealed within the protective housing and external cover. No radiation can leaak from the machine in the normal operation of the product by the user. 1.4.2 Handling the Laser Unit 0007-8181 The laser scanner unit emits invisible laser light inside it.

Chapter 1 1.4.3 Safety of Toner 0002-8619 The machine's toner is a non toxic material composed of plastic, iron, and small amounts of dye. Do not put the toner into fire. It may explode. Toner on the Skin or Clothes 1. If your skin or clothes came into contact with toner, wash with water at once. 2. Do not use warm or hot water, which will cause the toner to jell, permanently fusing it with the fibers of the clothes. 3. Do not bring toner into contact with vinyl material.

PAGE 31
Chapter 2 The leaser beam reflected by the 4 facet mirror moves through the imaging lens arranged in front of the 4 facet mirror and the reflecting mirror to reach and focus on the photosensitive drum. When the 4 facet mirror rotates at a specific speed, the laser beam scans the photosensitive drum in keeping with the mirror rotation, thus drawing static images on the photosensitive drum. Memo: BD Fault The machine identifies a BD fault if it does not detect the /BDI signal within 0.

Chapter 2‫ޓ‬Running H/F 5 2.3 Image Formation 2.3.1 Overview/Configuration 2.3.1.
PAGE 33
Chapter 2 Drum Cover Shutter If the surface of the photosensitive drum is exposed to strong light, it develops what is know as "photo memory," which can cause white spots or black lines in images. To protect the drum against light, the machine is equipped with a drum cover shutter. The drum cover shutter must never be opened unless doing so proves to be absolutely necessary.

Chapter 2‫ޓ‬Running H/F 5 2.4 Pickup and Feed System 2.4.1 Overview/Configuration 2.4.1.
PAGE 35
Chapter 2 Pickup and Feed Operation (from the cassette) If the cassette paper sensor detects the presence of paper while the absence of paper is identified in the manual feed pickup assembly, the machine picks up paper from the cassette. When the main motor operates and the cassette pickup solenoid goes on, the cassette pickup roller makes a single rotation to pick up paper.

Chapter 2‫ޓ‬Running H/F 5 2.5.2 Protective Function 2.5.2.1 Protective Mechanisms 0002-8628 The machine is equipped with the following 3 types of protective mechanisms used to prevent its fixing heater from going awry. 1. protective mechanism by the CPU 2. protective mechanism by the fixing heater safety circuit 3. protective mechanism by the thermal fuse 1.
PAGE 39
Chapter 2 2.5.2.2 Detecting a Fault in the Fixing Assembly 0002-8630 The CPU identifies a fault in the fixing assembly for the following conditions (a. thorough g.) and operates as described: 1. the CPU causes the fixing heater drive signal to go Low to cut off the power to the fixing heater. 2. the CPU causes the relay drive signal to go Low to turn off the relay. 3.
