0Turn power switch ONThe machine is equipped with 2 power switches: main power switch and control panel power switch. The machine goes on when the main power switch is turned on (i.e., other than in low power mode, sleep mode). 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. 2. The socket-outlet shall be installed near the equipment and shall be easily accessible.

2 Analog Control Performed by the CISThe flow of analog image processing performed by the contact image sensor (CIS) is as follows: a. The light reflected by the original is collected by the rod lens array. b. The light is received by the CMOS sensor array. c. The CMOS sensor array converts the received light to an electric signal and outputs it. The CMOS sensor array consists of four channels (units). Each channel is provided with an output correction table to output an image signal after performing gain correction for the input brightness signal.

2-9 Enlargement/Reduction Magnification Change in Vertical Scan DirectionIn the Book mode or when the ADF is used In the vertical scan direction, the image is read at 100%. Magnification is changed by processing data on the main controller PCB.

Magnification Change in Horizontal Scan DirectionIn the horizontal scan direction, magnification is changed as follows depending on the selected magnification rate: 1) When magnification is reduced to 50-99% a. In the Book mode Data is processed on the main controller PCB with the original scan speed held at 61.5 mm/sec or 123 mm/sec. b. When the ADF is used The original feed speed is changed within the range of 61.5 mm/sec or 123 mm/sec to 246 mm/sec depending on the selected magnification rate. Data is not processed on the main controller PCB.

2 Detecting the Size of Originals OverviewThe original size is identified by the combination of presence and absence of output levels of the reflection type sensors as summarized in the tables below. - Absence of paper: The light reflected from the reflection type sensor changes when the copyboard cover is open/close. - Presence of paper: The light reflected from the reflection type sensor does not change when the copyboard cover is open/close. This machine is provided with the following sensors. Locations of the sensors are shown below. - Vertical scan direction: Reflection type photo sensors (2 locations for AB; 1 location for Inch) - Horizontal scan direction: Reflection type photo sensors (2 locations for AB; 2 locations for Inch)Original sensor 3 Original sensor 2A Upper left corner of original

2-114) The copyboard cover is closed (at an angle of more than 5 deg but less than 30 deg) Original sensor: Turns on and original size identification process 2 is performed.

5) The original cover is closed (at an angle of 5 deg or less) The original size is identified. Original sensor: Turns off. In identifying the original size, the data obtained in the original size identification process 1 is compared with the data obtained in the original size identification process 2 to check whether these two pieces of data are identical. Note that a wrong original size may be identified because the sensor output level does not change in the following cases: - When the original is A3-sized black - When the original is a book (its thickness does not allow the copyboard cover to close fully, making it difficult to detect the sensor level change).F-2-19

2) The copyboard cover opens (at an angle of more than 30 deg). Original sensor: Turns off.

2[Description of Control] - 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. 1) Dust detection is performed once at position A. 2) CIS moves to the position B and dust detection is performed once. 3) CIS moves to the position C and dust detection is performed once. 4-a) CIS moves to the position where there is no dust, with priority for the detecting position; A>B>C. 4-b) If dust is detected at all points A, B, and C, move back to position A and the original is scanned at position A. PointA B C

2-13- Immediately before scanning (one sheet at a time) The contact image sensor (CIS) does not move to detect dust. The original is read at the position determined at job end or start. If presence of dust is detected there, the read image is corrected.

2 CMOS Sensor DriveThe CMOS sensor used in this machine is a 1-line linear image sensor consisting of 7488 photocells. After completion of photoelectric conversion in the lightreceiving block, the signals are output to the AP circuit in the reader relay PCB in parallel for each channel (total four channels) of the CMOS sensor array.

2-15 Shading Correction (Outline)The CMOS sensor outputs are necessary even for the following reasons even when the density of the original is uniform: (1) Variation in sensitivity among CMOS sensor pixels (2) Variation in light intensity of rod lens array The machine performs shading correction to even out the CMOS sensor output. There are two types of shading correction: shading adjustment performed in the Service

Shading CorrectionThe machine performs shading correction for each scan. It measures the density of the standard white plate, and compares the measured value with the target value stored in the shading correction circuit to use the difference between the two as the shading correctionoutput L L H H L H L H H H L

value. The machine uses this shading correction value to correct the variation among CMOS sensor pixels when scanning the original, thus evening out the image density level.CMOS sensor output Target value Measurement value

F-2-28 CMOS Sensor Output Gain Correction and Offset Correction

The analog video signals output from the CMOS sensor are corrected so that they will have a specific gain level (gain correction), and the output voltages generated in the absence of incident light are also corrected so that they it will have a specific offset level (offset correction).
