Page 21: Explanation Of Operation
Oki Data CONFIDENTIAL EXPLANATION OF OPERATION Electrophotographic processing mechanism (1) Electrophotographic process The electrophotographic process is explained briefly below: 1. Charging A voltage is applied to the CH roller to electrically charge the surface of the OPC drum. 2. Exposure The LED head radiates light onto the charged OPC drum in accordance with the image signal.
Page 22 Oki Data CONFIDENTIAL 2. Exposure The light emitted from the LED head is radiated onto the charged surface of the OPC drum. The charge of the radiated part of the OPC drum attenuates according to the intensity of the light, forming an electrostatic latent image on the OPC drum surface.
Page 23 Oki Data CONFIDENTIAL 4. Transfer A sheet of paper is placed over the OPC drum surface, and an electric charge is given to the paper from its back side by the transfer roller. When a high voltage is applied to the transfer roller from the power source, the charge...

Page 25 Oki Data CONFIDENTIAL 8. Fuser The toner image which was transferred to the paper is applied heat and pressure as it passes between the heat roller and the backup roller, and it is therefore fused onto the paper. For the sake of safety, a thermostat is provided; it comes on to cut off the voltage supplied to the heater if the heat roller temperature rises above a certain preset temperature.
Page 26: Printing Process
Oki Data CONFIDENTIAL Printing process The paper fed from Tray 1 or Tray 2 is carried by the paper feed roller, register roller L and transport roller. When the paper is fed from the MPT, it is carried by the MPT paper feed roller and register roller U.
Page 27 Oki Data CONFIDENTIAL (1) Paper fed from 1st Tray 1. As illustrated in Figure 2-1, when the solenoid is ON, the register motor rotates (Counterclockwise turn), transporting the paper until the IN1 sensor comes ON. (When the solenoid is ON, the paper feed roller is driven.) 2.
Page 28 Oki Data CONFIDENTIAL (3) Transport belt 1. As the transport belt motor rotates in the direction of the arrow, the transport belt is driven. The belt unit consists of one transport roller placed immediately underneath each color drum, with a transport belt inserted in between them.
Page 29 Oki Data CONFIDENTIAL (4) Up/down-motions of ID units 1. The up/down-motions of the ID units take place driven by the lift-up motor. 2. Figure 2-6 shows the motions of the different ID units when the printer is operated for color print. As the lift-up motor rotates (Clockwise turn), the lift-up link slides to the left, causing the ID units to come down, as can be seen in Figure 2-6.
Page 30 Oki Data CONFIDENTIAL (5) Fuser unit and paper output 1. As illustrated in Figure 2-8, the fuser unit and delivery roller are driven by the DC motor. As the fuser motor rotates (Counterclockwise turn), the heat roller is turned. This roller fixes a toner image by heat and pressure.

Page 35 Oki Data CONFIDENTIAL Principle of toner sensor detection Toner LOW is detected by the toner sensor (Reflection sensor) installed inside the printer. The shielding plate is mounted inside the ID and rotates in synchronization with toner agitation. Moreover, the ID has a shutter fitted. The shutter is synchronized with the operation lever of the toner cartridge, and the toner sensor can detect that the toner cartridge has been loaded properly.

Page 193: Updating Scanner Firmware
Oki Data CONFIDENTIAL Updating Scanner Firmware There are two ways to update scanner firmware: one is by using an OKI network setup tool and the other is by running a scanner in loader mode. The followings are the steps to update.
Page 194 Oki Data CONFIDENTIAL An icon of MC560 is added. Choose the icon of MC560 and then select “Update Firmware” from the “Tools” menu. After the [Firmware File Selection] window appears, proceed to the folder where firmware files (*.spf) are stored, and select the relevant firmware file (*.spf).
Page 195 Oki Data CONFIDENTIAL When the display of the scanner changes to the standby screen, hold down the “Reset” button for five seconds to reset the scanner to the factory default settings. With this operation, update completes. When all the above is done, print a menu map of the scanner or go to Menu, Information, Firmware Version in the scanner operation panel, and make sure that the version of the irmware has been updated.
Page 196: Updating By Running The Scanner In Loader Mode
The flow of update is as follows: start the scanner in Loader mode first and then update only he system firmware with an “upload” tool. After that, update every firmware with an OKI network setup tool described in section 6.6.1 above.
Page 197 Note! Do not turn off the power during update. The scanner reboots. When the display of the scanner changes to the standby screen, continue operation to update the firmware as described in section 7.5.1 Updating with the OKI MFP Network Setup Tool. 197 /...
