Steel ball. Fitting the Mirror Positioning Tool Use the mirror positioning tool FY by changing its pin arrangement as shown below. Note that [1] [2] [3] in the figures indicate the locations of the pins, while [A] [B] [C] indicate the pins.

Caution: Note that pin [A] of the mirror positioning tool FY will not be used for the machine. Adjusting the Mirror Position optical length between No.


The same applies to the rear side plate. Various correction and processing are performed in the following PCBs, each sending resulting image signals to the next PCB. Printer Motherboard. Printer Board. The signals photo-converted by the light-receiving unit are transferred to canon ir 300-405 printer analog signal processing block odd- and even-numbered pixels are communicated separately.

White background original Colored background original The ABC circuit processes the reference original surface voltage to reduce the FFH white level, i. Adjustments will vary the density correction curve; a lower setting will make the text darker. Higher Lower setting setting.

Black Original density Black White. Increases or decreases in the reference voltage will in turn increase or decrease the dynamic range difference between maximum output level and minimum output level. Outline The digital image processing block processes image signals from the analog image processing block or from the various extension boards. Figure is a block diagram showing the items of processing. In the case of making a single copy a single copy from a signal originalthe image data is converted to dpi equivalent images by smoothing after binary processing, and is sent to the laser driver PCB direct copying.

Shading Correction The output of the CCD does not necessarily match the light reflected by an original although the original may have an even density for the following reasons: 1. The sensitivity differs from one pixel of the CCD to another. The degree of lens canon ir 300-405 printer is different between middle and edges. The scanning lamp deteriorates.

The resulting variations are corrected by means of shading: shading correction executed canon ir 300-405 printer each copying run, and shading auto correction whose target value is set in service mode. In shading auto correction, the density of the white standard plate and white paper is measured by the CCD PCand the collected data is stored in memory. The data is then subjected to computation, and the result will be used as the "target value" at time of shading correction. Shading Correction Shading correction is executed for each scan of an original.

The light of the scanning lamp is directed to the standard white plate Figureand the light reflected by the plate is converted into digital signals by the CCD PCB. The resulting digital signals are sent to the shading circuit on the image processor PCB as canon ir 300-405 printer data.

The shading circuit compares the shading data against the target value stored in memory, and sets the difference as the shading correction value. The shading correction value is used to correct the variation among the pixels of the CCD occurring during scanning operation, thereby evening out the image density level. Scanning canon ir 300-405 printer Characteristic after correction No.
