Page 12: Laser Safety
Safety Precautions Laser Safety Since radiation emitted inside the machine is completely confined within protective housings and external covers, the laser beam cannot escape from the machine during any phase of user operation. Therefore this machine is classified in Class 1 laser products that are regarded as safe during normal use according to International Standard IEC60825-1.
Page 13: Power Supply
Safety Precautions Control panel power switch Main power switch Power Supply CAUTION: 1. As a general rule, do not use extension cords. Using an extension cord may result in a fire or electrical shock. If an extension cord must be used, however, use one for local rated voltage and over, untie the cord binding, and insert the power plug completely into the extension cord outlet to ensure a firm connection between the power cord and the extension cord.

Page 43: Image Processing
2. Technical Explanation • At job end (Dust detection) The contact image sensor (CIS) checks the light reflected by the ADF platen roller surface at the read position for presence/ absence of dust. After completion of a job,dust detection is performed in the positions A, B and C without concern of presence/absence of dust.
Page 44 2. Technical Explanation The reader relay PCB is used to process images on a line-by-line basis. Its major functions are as follows: 1. Analog image processing • CMOS sensor drive • CMOS sensor output gain correction and offset correction • CMOS sensor output A/D conversion 2.
Page 45: Shading Adjustment
2. Technical Explanation There are two types of shading correction: shading adjustment performed in the Service mode and shading correction performed for each job. ● Shading Adjustment The machine measures the density of the standard white plate, and stores the measured density data. It then processes the stored data to use it as the target value for shading correction.

Page 70: Toner Level Detection
2. Technical Explanation If the developing unit toner sensor (TS1) detects the absence of the toner in the developing unit, the hopper motor (M7) drives to rotate the toner feed screw to feed toner in the sub hopper to the developing unit. Also, if the sub hopper toner sensor (TS2) detects the absence of the toner in the sub hopper, the bottle motor (M7) drives to rotate the toner cartridge to feed the toner in the toner cartridge to the sub hopper.
Page 71 2. Technical Explanation Toner level Status Message Alarm Operation 100 to 11% When the sub hopper toner sensor (TS2) detects absence of toner, the bottle motor (M6) is driven. Once the sub hopper toner sensor (TS2) detects presence of toner, the bottle motor (M6) is stopped (to pre- vent toner leak).

Page 113: Faq
2. Technical Explanation Q1: Registration information of an E-RDS is once deleted from the UGW server, and is reregistered after that. If a communication test is not carried out, then device information on the UGW becomes invalid. A1: When registration of the E-RDS is deleted from the UGW, the status will be changed to that the communication test has not completed because related information has lost from a database.
Page 114 2. Technical Explanation Causes: Initial settings or network conditions is incomplete. Remedy1: 1. Check network connections Is the status indicator LED for the HUB port to which the main unit is connected ON? YES: Proceed to Step 2). NO: Check that the network cable is properly connected. 2.
