For a reduction between 25% and 49%, image data read at 50% to 98% is subjected to skipping (1/2) in the main controller assembly. For reduction between 50% and 99%, the speed of the mirror/original is increased e.g., at 50%, the speed is twice as high as that used in Direct. For enlargement, the speed of the mirror/original is reduced from that used in Direct: e.g., at 200%, the speed is 1/2 of the speed used in Direct. However, for a reduction between 25% and 49% and enlargement between 401% and 800%, data processing in the main controller assembly is also used in combination. To enlarge, data units are repeated.ġ.2.2 Changing the Reproduction Ratio in Sub Scanning Directionįor sub scanning direction, the speed of the scanner/movement of the original is changed. If for a reproduction ratio of 25% to 400%, the speed of the movement of the original is changed.ġ.2.1 Changing the Reproduction Ratio in Main Scanning Directionįor scanning direction, reading is always at 100% in both copyboard and ADF modes the ratio is changed in the course of data processing in the main controller assembly. If for a reproduction ratio of 25% to 800%, the speed of the scanner is changed. Sub scanning direction: by reflection type sensorġ.2 Changing the Reproduction Ratio (Zoom) Control of activation by inverter circuit 2 mirror base: control by stepping motor (M400) Main scanning direction: image processing by controller assembly ![]() The original exposure system has the following major functions: Reader controller PCB controls the reader unit, controls the DADF communication DC controller PCB controls the printer unit, controls the finisher communication Man controller PCB controls the system as a whole, processes images The major electrical mechanisms of the machine are controlled by the following PCBs: The above specifications are subject to change for product improvement.ģ.2.1 Construction of the Electrical Circuit *2:The values within parentheses indicate when the DADF is used. *1:The HDD that comes with the machine and the HDD that is made available as a service part may have different memory sizes however, the area of the HDD used by the machine will be the same, and either may be used without a problem. ![]() Network Multi-PDL Printer Kit-A1 (120/230V model.Network LIPS Printer Kit-A1 (100V model only).Options Power Supply-B1 (required for SF, PD). ![]() Yes (-10% standard may be changed in user mode to.
