PAGE 41
Chapter 2 8) When the four-sided mirror rotates at a constant speed, the laser beam striking the photosensitive drum scans on the drum at a constant speed. 9) When the photosensitive drum rotates and the laser beam scans on the photosensitive drum, at each specified speed, a latent image is formed on the drum. Twin beam method Two laser diodes (LD1, LD2) are built into the laser unit. In one scanning operation, the laser unit emits light from the LD1 and LD2 and writes two lines simultaneously.

When the laser drive IC goes into print mode, the laser driver PCB turns on the laser diodes with a specified amount of light or turns it off according to the VIDEO (VDO1, /VDO1, VDO2, /VDO2) signals sent from the SCNT Board. 2.2.2.

Step 9: Auxiliary ITB cleaning roller charging - Residual toner on the ITB is charged in order to be held on the ITB. Step 10: ITB cleaning roller charging - Residual toner on the ITB is charged. Step 11: ITB cleaning - Residual toner on the ITB is transferred onto the drum. Step 12: Drum cleaning - Residual toner adhered to the drum is cleaned. 2.3.1.

Chapter 2 Blade Photosensitive drum Stirrer DC bias Developing cylinder DC bias F-2-17 Step 3: Auxiliary development In this step, CPU applies DC bias onto the toner that was not charged by frictional electrification. Here, the toner becomes uniformed negative potential. The printer charges the uncharged toner by applying DC bias onto the blade inside the toner cartridge. The DC bias is also used as developing bias.
PAGE 47
Chapter 2 ITB Toner Photosensitive drum DC bias Primary transfer roller F-2-19 Step 6: Secondary transfer The toner on the ITB is transferred onto paper in this step. A DC positive bias is applied to the secondary transfer roller to charge the back side of a fed paper. This allows the toner on the ITB to transfer onto paper positively. At the completion of secondary transfer, a DC negative bias is applied to the secondary transfer roller to avoid soiling the back of paper with the toner on the ITB.
PAGE 48
Chapter 2 The machine uses an on-demand method, which requires a low thermal capacity. The method enables the machine to start up quickly and its heater to use little power while the machine is in a standby state. The machine may therefore be characterized by a short wait time and low energy consumption. The machine applies a positive DC bias to its pressure roller for the purpose of reinforcing the retention of toner on print paper, consequently preventing stray toner.

Chapter 2 2.3.2 Driving and Controlling the High-Voltage System 2.3.2.1 Outline 0011-6381 In this circuit, biases are applied to the primary charging roller, developing cylinder, primary transfer roller, secondary transfer roller, auxiliary ITB cleaning roller, ITB cleaning roller, and fixing film. The CPU (IC101) in the DCNT Board controls the high-voltage power supply circuit and the sub high-voltage power supply circuit through the ASIC (IC102) to generate the biases.
PAGE 51
Chapter 2 In full-color printing, as four toner layers in each colors are piled up on the ITB in primary transfer, the holding force of toner weakens as the transfer process progresses for the 1st color, 2nd color... Therefore, after transferring the first color, the primary transfer DC (positive) bias is increased for the toner in the rest of the colors to gain the holding force of the toner. 2.3.2.

Chapter 2 2.3.3.2 Image Density Calibration (D-max) Control 0008-1704 This control is performed to stabilize the image density of the printer engine. The DCNT Board forms density patterns in each color on the ITB as varying the developing bias when specified conditions are met. Then the DCNT Board measures the density of the patterns with the density sensor and controls the developing bias to obtain a proper density based on the measured density. 2.3.3.

If the drive release lever is in low position (i.e., with drive engaged), it forces out the coupling [2], causing the coupling to interface with the drum cartridge and to suffer damage.
