Chapter 1 Running H/F 5 1.4 Safety 1.4.1 Safety of Laser Light 0002-8615 Laser radiation could be hazardous to the human body. 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.
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.
Chapter 2 2.1 Document Feed and Exposure System 2.1.1 Overview/Configuration 2.1.1.1 Overview 0007-8185 F-2-1 T-2-1 [1] Flatbed motor [2] CCD unit The CCD unit driven by the flatbed motor reads out image data of a document on the platen glass.
Chapter 2 Running H/F 5 2.2 Laser Exposure 2.2.1 Overview/Configuration 2.2.1.1 Overview 0002-8624 F-2-2 T-2-2 [1] Laser driver PCB [5] Imaging lends [2] BD sensor [6] Scanner motor [3] Reflecting mirror [7] 4 facet mirror [4] Photosensitive drum [8] Cylindrical lens The machine's laser scanner assembly consists of the laser driver and the scanner motor, which are driven by signals coming from the engine controller.
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.
Chapter 2 Running H/F 5 2.3 Image Formation 2.3.1 Overview/Configuration 2.3.1.1 Overview 0002-8626 F-2-3 T-2-3 [1] Laser/scanner assembly [5] Photosensitive drum [2] Laser beam [6] Transfer charging roller [3] Blade [7] Primary charging roller [4] Developing cylinder [8] Cleaning blade In response to a print command, the engine controller turns on the main motor to drive the photosensitive drum, developing cylinder, primary charging roller, and transfer charging roller.
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.
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 2 Running H/F 5 2.4.2.2 Delay Jams 2.4.2.2.1 Pickup Delay Jam 0003-0657 If the top sensor does not detect the leading edge of paper within 1.2 sec after the start of pickup operation, the machine initiates pickup operation once gain. The machine identifies a pickup delay jam if the top sensor does not detect the leading edge of paper within 1.2 sec after the 2nd pickup operation.
Chapter 2 2.5 Fixing Unit 2.5.1 Overview/Configuration 2.5.1.1 Overview 0002-8627 F-2-5 T-2-5 [1] Fixing film unit [2] Fixing heater [3] Pressure roller The machine's fixing system is an on demand type, and its fixing assembly consists of the fixing film unit and the pressure roller: the fixing film has a built in fixing heater, thermistor, and thermal fuse.
Chapter 2 Running 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.
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.
Chapter 2 Running H/F 5 2.6 External and Controls 2.6.1 Power Supply 2.6.1.1 Energy Saving Function 2.6.1.1.1 Overview 0007-6468 This machine has the Energy Saver mode. When Energy Saver in the User Menu is set to ON, and no operation is made for approx.
