CAUTION
This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved on the eye’s retina, there is the danger of spot damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.
1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not as individual parts.
2) Do not look into the machine with the main switch turned on after removing the developer unit, toner cartridge, and drum cartridge.
3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and installing the optical system.
4) The middle frame contains the safety interlock switch. Do not defeat the safety interlock by inserting wedges or other items into the switch slot.
LASER WAVE – LENGTH : 780 ∼ 795 Pulse times : 0.481 ms/6 mm Out put power : 0.20 ± 0.03 mW
CAUTION
INVISIBLE LASER RADIATION, WHEN OPEN AND INTERLOCKS DEFEATED. AVOID EXPOSURE TO BEAM.

At the production line, the output power of the scanner unit is adjusted to 0.57 MILLI-WATT PLUS 20 PCTS and is maintained constant by the operation of the Automatic Power Control (APC). Even if the APC circuit fails in operation for some reason, the maximum output power will only be 15 MILLI-WATT 0.1 MICRO-SEC. Giving an accessible emission level of 42 MICRO-WATT which is still-less than the limit of CLASS-1 laser product.
Caution
This product contains a low power laser device. To ensure continued safety do not remove any cover or attempt to gain access to the inside of the product. Refer all servicing to qualified personnel.
The foregoing is applicable only to the 220V
230V model and 240V model.

Setting conditions
1)Set copy conditions such as the copy quantity and the copy density with the operation section, and press the COPY button. The information on copy conditions is sent to the MCU.
Image scanning
2)When the COPY button is pressed, the scanner section starts scanning of images. The light from the copy lamp is reflected by the document and passed through the lens to the CCD.
Photo signal/Electric signal conversion
3)The image is converted into electrical signals by the CCD circuit and passed to the MCU.
Image process
4)The document image signal sent from the CCD circuit is processed under the revised conditions and sent to the LSU (laser unit) as print data.
Electric signal/Photo signal (laser beam) conversion
5)The LSU emits laser beams according to the print data. (Electrical signals are converted into photo signals.)
6)The laser beams are radiated through the polygon mirror and various lenses to the OPC drum.
Printing
7)Electrostatic latent images are formed on the OPC drum according to the laser beams, and the latent images are developed to be visible im­ages (toner images).
8)Meanwhile the paper is fed to the image transfer section in synchronization with the image lead edge.
9)After the transfer of toner images onto the paper, the toner images are fused to the paper by the fusing section. The copied paper is discharged onto the exit tray.

2.Scanner section
A.How to scan documents
The scanner has sensors that are arranged in a line. These sensors scan a certain area of a document at a time and deliver outputs sequentially. When the line is finished, the next line is scanned, and this procedure is repeated. The figure below shows the case where the latter two sections of an image which are scanned are shown with solid lines and the former two sections which are being transmitted are shown with dotted lines. The direction of this line is called “main scanning direction,” and the scanning direction “sub scanning direction.” In the figure above, one line is divided into 4 sections. Actually, however, one line is divided into thousands of sections. For scanning, the light receiving ele­ment called CCD is used. The basic resolution indicates the scanner capacity. The basic resolution is ex­pressed in dpi (dot/inch) which shows the number of light emitting elements per inch on the document. The basic resolution of this machine is 400dpi. In the sub scanning direction, at the same time, the motor that drives the op­tical system is controlled to scan the image at the basic resolution.

10Mirror motor11MHPS (Mirror home position sensor)
The scanner unit performs scanning in the digital optical system. The light from the light source (Xenon lamp) is reflected by a document and passed through three mirrors and reduction lenses to the CCD element (image sensor) where images are formed. This system is known as the reduction image sensor system. Photo energy on the CCD element is con­verted into electrical signals (analog signals). (Photo-electric conversion). The output signals (analog signals) are converted into digital signals (A/D conversion) and passed to the MCU (main control/image process section). The resolution at that time is 400dpi. The mirror unit in the scanner section is driven by the mirror motor. The MHPS is provided to detect the home position of the copy lamp unit.

3.Laser unit
The image data sent from the MCU (image process circuit) is sent to the LSU (laser unit), where it is converted into laser beams.
A.Basic structure
The LSU unit is the writing section of the digital optical system. The semiconductor laser is used as the light source, and images are formed on the OPC drum by the polygon mirror and fθ lens, etc. The laser beams are passed through the collimator lens, the cylindrical lens, the polygon mirror, the fθ lens, and the mirror to form images on the OPC drum in the main scanning direction. The laser emitting PWB is provided with the APC (auto power control) in order to eliminate fluc­tuations in the laser power. The BF PWB works for measurement of the laser writing start point.

(1)Cassette paper feed operation
1)The figure below shows the positions of the pick-up roller, the paper feed clutch sleeve, and the paper feed latch in the initial state without pressing the COPY button after lighting the ready lamp. The paper feed latch is in contact with the projection of the clutch sleeve.
2)When the COPY button is pressed, the main drive motor starts rotating to drive each drive gear. The pick-up drive gear also is driven at that time. Since, however, the paper feed latch is in contact with the projection of the clutch sleeve, rotation of the drive gear is not transmitted to the pick-up roller, which does not rotate.

5)At this time, the paper is fed past the paper entry detection switch (PPD1), and detected by it. After about 0.15 sec from detection of paper by PPD1, the tray paper feed solenoid (PFS) turns on so that the clutch sleeve projection comes into contact with the paper feed latch to stop the pick-up roller. Then the pick-up roller rotates for about 0.15 sec so that the lead edge of the paper is evenly pressed on the resist roller, preventing against skew feeding.

3)After about 0.1 sec from when the main motor start rotating, the tray paper feed solenoid (PFS) turns on momentarily. This disengages the paper feed latch from the projection of the clutch sleeve, transmitting rotation of the pick-up drive gear to the paper feed roller shaft, rotating the pick-up roller to feed the paper.

6)To release the resist roller, the tray paper feed solenoid and the resist solenoid are turned on by the paper start signal to disengage the resist start latch from the clutch sleeve projection, transmitting rotation of the resist drive gear to the resist roller shaft. Thus the paper is transported by the resist roller.
7)After the resist roller starts rotating, the paper is passed through the pre-transfer guide to the transfer section. Images are transferred on the paper, which is separated from the OPC drum by the drum curve and the separation section.
