7. Write section (PH section) Theory of Operation Ver. 2.0 Nov. 2007 7.2.5 Laser emission area A. Main scan direction (CD) • The laser emission area is determined by the paper size. • Laser is emitted to the area except for a 3.0 mm band at both paper sides. B.
Page 50: Registration Control (Color Shift Correction) System
Theory of Operation Ver. 2.0 Nov. 2007 7. Write section (PH section) 7.2.6 Registration control (color shift correction) system A. Overview of the registration control • In a tandem engine, in which an independent image reproduction process is provided for different colors, incorrect color registration, or color shift, is more likely to occur due to individual PH assemblies being out of correct position or the relevant parts being out of accuracy.
Page 51 7. Write section (PH section) Theory of Operation Ver. 2.0 Nov. 2007 B. Types of color shift • Color shift is misalignment of the images of three different colors, yellow (Y), magenta (M), and cyan (C), with respect to the image of black (K). •...
Page 52 Theory of Operation Ver. 2.0 Nov. 2007 7. Write section (PH section) D. Correction of color shift due to overall scaling error in the main scan direction • If the image of each color (Y, M, C) and the image of black (K) vary in length in the main scan direction, changing the clock frequency of the laser diode can correct the length dif- ference in the main scan direction.
Page 53 7. Write section (PH section) Theory of Operation Ver. 2.0 Nov. 2007 F. Skew (image skew) • If the image of each color (Y, M, C) is tilted against the image of black (K), the image skew can be corrected by changing the angle at which the printer head is mounted on the main body installation plate.
Page 54: Skew Control Mechanism
Theory of Operation Ver. 2.0 Nov. 2007 7. Write section (PH section) 7.2.7 Skew control mechanism • When the printer head is mounted on the main body installation plate, image distortion (skew) occurs due to mounting error. Therefore the printer head adopts the correction system.

Theory of operation Ver. 1.0 Nov. 2007 5. Operation 5.4.2 Transport operation in center staple & fold section A. Paper transport • After a stack of paper has been aligned on the finishing tray, it is taken up with the upper and lower exit rollers.
Page 273 5. Operation Theory of operation Ver. 1.0 Nov. 2007 B. Stapling • The stack of paper is further transported and temporarily stopped when the center area of the paper (the area where stapling will be made) has reached the position of the sta- ples in the staple unit.
Page 274 Theory of operation Ver. 1.0 Nov. 2007 5. Operation C. Booklet transport • Next, the stack of paper that was stapled is transported to the paper folding / exit position with the transport rollers. The paper folding /exit position is the position where the center of the paper (where stapled) is of the same height as that of the paper pressure plate and nip area of the folding rollers.
Page 275 5. Operation Theory of operation Ver. 1.0 Nov. 2007 D. Folding/exit • The paper pressure plate presses the center of the paper to transport the paper toward the paper folding rollers. Then the paper folding rollers take up and fold the paper and feed the stack of paper onto the exit tray 2 through the folding, and the booklet exit roll- ers.

Theory of operation Ver. 1.0 Nov. 2007 5. Operation 5.4.3 Folding mechanism • The paper folding mechanism consists of the folding rollers and paper pressure plate. • They are driven by the staple/ folding motor respectively through the combination of the gears and cams etc.

5. Operation Theory of operation Ver. 1.0 Nov. 2007 5.4.4 Paper folding start position • Paper folding is created by the paper folding plate and the paper pressure plate. At the same time when the folding rollers start to rotate, the paper pressure plate starts press- ing the stack of paper to the contact area of the paper folding rollers.
