Chapter 1 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 2 F-2-2 T-2-2 [1] Document feed motor [3] CCD unit [2] Flatbed motor Reading from the ADF To avoid skew feeding, documents loaded on the document tray are retained in the horizontal direction by the slide guide. Then, the documents are fed to the separation roller by the pickup roller, and separated one sheet each using differences in the coefficient of friction among the separation roller, documents, and separation guide.
Chapter 2 2.2 Laser Exposure 2.2.1 Overview/Configuration 2.2.1.1 Overview 0002-8624 F-2-3 T-2-3 [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 36
Chapter 2 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 0.1 sec after the scanner motor is forced to accelerate.
Chapter 2 2.3 Image Formation 2.3.1 Overview/Configuration 2.3.1.1 Overview 0002-8626 F-2-4 T-2-4 [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 38
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.
Page 41
Chapter 2 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-2-6 T-2-6 [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 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 2.6 External and Controls 2.6.1 Power Supply 2.6.1.1 Backup Battery 2.6.1.1.1 Battery-backed up Data 0006-5544 The SCNT board is provided with a function for backing up data in control / clock IC and image storage memory (DRAM) by lithium battery (BAT951), and capacitor (C958), even if a power interruption occurs, or the power cord is disconnected by accident.
Page 46
Chapter 2 2.6.1.2 Energy-Saving Function 2.6.1.2.1 Overview 0006-5613 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. 5 minutes or more in the stand-by mode, the machine enters the Energy Saver mode. When the Energy Saver key on the control panel is pressed, it also enters the Energy Saver mode.

Using the error code, the user or the service man can readily find out how to correct the fault by simply referring to the User's Manual or service manual.
Chapter 5 5.5.2.2 #001 [TX] Document has jammed 0007-2927 Cause The document is trapped in the feeder. Remedy Remove the document, and try again. Cause The document is not of a standard size or thickness. Remedy Using a copying machine, make an A4/LTR copy of the document to transmit. Cause An internal mechanism is faulty.
Chapter 5 Cause The data of a single page is too large, exceeding the time allowed for reception. Remedy 1) Ask the operator of the other party to decrease the reading resolution and transmit. 2) Ask the operator of the other party to divide the document and transmit. 3) Increase the setting of the page timer with Service Data #1 SSSW SW12.
Chapter 5 Cause The other party's communication mode (G2, G3, etc.) does not match. Remedy The communication mode depends on each specific model, and no remedy can be offered. Cause During transmission, the other party malfunctioned because of an echo. Remedy 1) Using a manual call, press the Start button after hearing the 1st DIS from the other party.
Chapter 5 Cause An internal mechanism is faulty. Remedy 1) Check the top sensor, the paper delivery sensor, the cassette paper sensor, and the manual paper sensor for breakage or deformation. 2) Check the paper delivery sensor and the DCNT board (J508) connections. 3) Check the top sensor and the DCNT board (J507) connections.
Chapter 5 5.5.3.3 E100 Laser/Scanner Unit Failure 0007-2946 Cause: Laser/Scanner unit failure. Remedy: 1) Turn the power off and on. 2) Make sure that the Laser/Scanner unit (J801) and DCNT board (J503) are properly connected. 3) Make sure that the Laser/Scanner unit and DCNT board (J504) are properly connected. 4) Make sure connections of the boards (power supply board (CN101), DCNT board (J501), and SCNT board (J804)).
