2-6 Confidential 3.2.1 Scanner unit The scanner unit is equipme nt which scans the paper using the CCD unit. This machine prints the sca nning data (copy) or dat a is sent by fax (fax transmission). There are two kinds of scannin g method of the scanner unit.
2-7 Confidential 6. Sca nning operation (The CCD unit moves under the immovable documen t.) Open the document cover , place a sheet of the document (or opened book) onto the document glass, and close the document cover .
2-8 Confidential 3.2.2 ADF unit The ADF unit is equipment which sends on e docum ent or the document for every p lurality to the ADF scanning part of th e scanner unit, and performs continuation scannin g. As for the ADF of this machine, the dupl ex sca nning is also possible.
2-9 Confidential 4. In ternal structure The autom atic docum ent feede r (ADF) cons ists of the pick-u p roller , separation rolle r , paper fe ed rollers 1/2/3/4, eject roller , ADF motor , switch back sensor , document rear sensor and docume nt front sensors 1/2.

2-12 Confidential (4) The SB (switch back) ro ller ASSY is turned counter again, and the document is drawn again. The document is p assed through the paper feed roller s 1, 2 and 3, and ejected to the document cover by the eject ro ller .
2-13 Confidential 3.3 Paper Feeding Fig. 2-12 L T path DX path MP path Paper tray path.
2-14 Confidential 3.3.1 Plate-up Function of the Paper T ray The plate ASSY in the p aper tray is pushed up with the motor dr ive and not with the spring in order to maint ain the constant pressure to the feed roller and to gi ve the paper feeding performance.
2-15 Confidential 3.3.2 Paper supply The feed roller picks up a few she ets or one shee t of p aper from the paper tray every time it is rotated and feed s it to the separation roller . Fig. 2-15 The main motor drive power is tr ansmitted to the gears, and the feed roller a nd separation roller are rot ated.
2-16 Confidential 3.3.3 Paper registration After the p aper top position is detected by the re gist actuator front, the paper , separated into individual sheet s by the separation roller , is fed further for a specified time, and the paper top position reaches the regist ro lle r so that the paper skew is adjusted.
2-17 Confidential 3.3.4 Paper eject After the printi ng image on the exposure drum is transferred onto the p aper , the paper is fed to the fuser unit to fix unfixe d toner onto the paper by the heat roller and the pres sure roller in the fuser unit. Afterwards, the paper is ejected fr om the fus er unit.
2-18 Confidential 3.3.5 Duplex printing After the p aper exits from the eject roller ASSY with the front of sheet pr inted, the eject roller ASSY rotates conversely and fe eds the p aper to the DX un it, where the paper skew is adjusted.
2-19 Confidential 3.3.6 Paper feeding from the MP tray The separation r oller MP is connected with the feed roller through the gea r in the MP roller holder ASSY .

2-21 Confidential 3.4.2 Cartridge life A new toner cartridge can p rint approximately 3,000 (st andard toner) or approximately 8,000 (high yield toner) A4 or Letter size single-sid ed pages at normal duty (ISO/IEC19752).
2-22 Confidential 3.4.3 New toner detection (1) The main motor will drive gear (4) thro ugh the interconnection of other gears. (2) When gear (4) is rotated, rib A on that gear will push against the n.
2-23 Confidential When the new toner detectio n switch detects that the to ner cartridge is replaced with a new one, the developing bia s voltage is initialized at the same time. The toner used for the printer has a property th at print density is lig ht first and gradually darker in the course of usage.
2-24 Confidential <When a toner cartri dge in use is inserted af ter "Replace T oner" is displayed by toner sensor detection *1 > A count value before change s is continuously in dicated as a rotation rate of the develo p roller .
2-25 Confidential 3.5 Print 3.5.1 Basic Principle The printing pro cess consists broadly of 5 proc esses: electrification, exposure, de velopment, transfer and fusing. 1. Charging: The surface of an exposure drum is electrically charged. 2. Exposure: A printed ima ge is forme d on the su rface of th e drum b y applying laser beam .
2-26 Confidential 3.5.2 Print Process (1) Charging The flow of the ion charge is controlled b y consta nt voltage of the g rid 850 V to en sure it is distribute d evenly on the drum surface. In or der to coat toner on the exposure drum , the drum needs to be e venly electrified.
2-27 Confidential (2) Exposure The laser beam radiated from a laser dio de inside the laser unit is concentrated into a constant wid th by a slit in the CO lens cell and then reflected by a polygon mirror rot ating at high speed. The evenly cha rged exposure drum is irradiated with reflected light and exposed .
2-28 Confidential (3) Development T oner is attracted to a printed-image area on the exposure drum where surfac e potential is lowered due to exposure. By controlling develop ing bias voltage supplied to the develop roller , the amount of toner take n to the drum is adjusted to keep printing density constant.
2-29 Confidential (4) T ransfer By applying a minus ch arge to the transfer r o ller , the toner adhered to the exposure drum is transferre d to paper . Fig. 2-27 Memo : • Control of transfe r bias The transfer bias applied in th e transfer roller is adjusted a ccording to types and sizes of paper so as to keep excellent image quality .
2-30 Confidential (5) Fusing The toner transferred o n paper passes betwe en the heat roller and the pressure roller in the fuser unit, being fused by heat and pr essure. The thermistor detects surface temperature of the heat roller and tur ns ON/OFF the halogen heater lamp.
