    To support iR machines. To enhance image processing performance. Made to use lines for the dither screen method for To enhance the resolution of print photos. Chapter 3 Main Controller print photo mode. Reader controller Made to detect the orientation of only the 1st original. It consists of two CCDs connected to form a single entity each. Reading starts simultaneously at both left and right sides. The image data is divided into 4 channels: The following diagram shows how CCD data is transferred: If the CCD gain characteristics differ between its first half and its last half.

    Use it with the Gradation Chart. The following three methods may be used for adjustment: CCD correction must be ex- ecuted in service mode. Use any of the above methods as needed. Do not move to B or C without correctly executing A. Start with A. On the other hand. The machine uses the result of detection to determine the following: The GP iR detects the orientation of each original. The stored text data is Text area Text direction matched against the extraction block identification block fonts in the dictionary to find out the direction 2 of characters.

    The time it saves from not having to detect the orientation of all originals also helps increase its produc- tivity. To protect against static charge. Book Mode A: Removing the Hard disk 1 Remove the main control box. Do not subject the hard disk unit to impact. Take measures against static charges to protect against static damage.

    When Replacing the Hard Disk When replacing the hard disk unit. It is a twin-laser mechanism laser A. It scans the photosensitive drum main scanning direction to create a latent static image.

While the CPU reads the system software from the HDD to the SDRAM, the following screen remains in the control panel, with the progress bar on the screen indicating the changing stages of the start-up sequence: F E, Indicates an error in image transfer data.

    When the write operation ends, the system software in the SDRAM starts up to initialize the components of the machine at the end of which the normal operating screen will appear in the control panel and, at the same time, the LED lamp of the Start key will change from red to green to indicate that the machine is ready to accept a job.

    The system software of the machine consists of multiple modules, and specific modules as needed at specific times are called into the system area of the SDRAM for execution. F 1. To upgrade the machine, you will have to upgrade both the system modules and the language modules.

    Access to the program during execution: Flow of the system program. The following is a block diagram showing its digital image processing: The input is from 2 signal lines: LOG Conversion Using a LOG conversion table, the intensity signals are converted into toner density signals in relation to reflected light. Density Adjustment F-value conversion Using an F-value table selected in relation to the setting of the Density key in the control panel, density adjustment is performed.

    It, however, will not be performed in memory copy mode. Specifically, the 8-bit image density signals of text, text photo, or print photo mode are converted into 1-bit image density signals binary. Specifically, the 8-bit image density signals in film photo mode are converted into 1-bit image density signals binary. Notch processing is also performed in this block, as a pattern unique to read images. The counter readings are checked by pressing the Check key in the control panel.

    The counters are controlled by the main controller PCB, and the readings are incremented when the following sensors detect paper during copying or printing. T The counter mechanism consists of 16 items for large-size and small-size sheet, each with 8 mode items. At time of shipment from the factory, B4 or smaller; to count B4 as large-size, use service mode. Not counted; the machine is not equipped with fax functions. PS14 2nd side: The notation within parenthesis indicates modes supported by the basic counter see T This, however, does not apply to counter 1, whose data cannot be changed.

    T 4. Not only the main controller PCB, but also the reader unit, printer unit, and control panel are all ready for communication and control. In this mode, the CPU on the main controller PCB is also at rest in wait for an interrupt and not running the program to reduce power consumption.

    This mode is used only when the machine is configured as a printer equipped with a network print option and a PDL print option. This mode is used when the machine is configured as a copier without a network print option or a PDL print option. The operation at time of return will be exactly the same as when the machine is first turned on. To return from power OFF mode, the main power switch must be turned on, in response to which the machine will automatically enter standby mode.

    The site must provide with a power outlet that is rated to suit the machine and that can be used exclusively by the machine; V Model to V, 12A or more , V Model to V, 12A or more , V Model to V, 13A or more. Particularly, be sure to avoid areas near water faucets, water boilers, humidifiers, and refrigerators. The site must not be near a source of fire, subject to dust or ammonium gas, or exposed to direct rays of the sun.

    As necessary provide curtains. The level of ozone generated by the machine will not affect the health of individuals around it. Some, however, may find its odor unpleasant as while remaining in contact with it for long hours. Be sure that the room is well ventilated. Make sure that the feet of the machine will remain in contact with the floor, and the machine will be kept level. Make sure that the machine will be at least 10 cm away from any walls, allowing enough space for work.

    Make sure that the area is well ventilated. If multiple machines are installed, in particular, be sure that the exhaust of another will not be drawn by the machine. Be sure also not to install a machine near an air vent. F In general, the silicon gas vapor of silicone oil from the fixing assembly tends to soil the corona charging wire, reducing its life. This is particularly true of a low humidity environment.

Use of the machine while it suffers from condensation can lead to image faults. If the machine has been moved from a cold to warm place, be sure to leave it for 1 hour or more without unpacking so that it becomes fully used to the new place.

    If stairs are used to move the machine into or out of the site of installation, keep the following in mind: Instead, be sure to support the machine at four corners of its bottom. Shift up the 2 adjusters front found on the bottom of the machine to be sure that they are unlocked. The adjusters can slip out of the bottom of the machine because of vibration during transportation.

    Take care not to loose them. Be sure to work as a group of three or more.
