30 March 1999 MECHANISM OVERVIEW 1.2 MECHANISM OVERVIEW 1.2.1 IMAGE GENERATION PROCESS A269V101.WMF 1. Drum charge The charge corona applies a negative charge to the OPC drum and the grid ensures that this charge is even. 2. Quenching After cleaning, the OPC is fully exposed to light from an array of red LEDs, quenching the residual charge on the OPC drum in preparation for the next copy cycle.
Page 26 MECHANISM OVERVIEW 30 March 1999 5. Image transfer to image transfer belt Positive charge applied to the back of the image transfer belt transfers the toner image on the OPC drum to the image transfer belt. 6. Image transfer to paper The negatively charged toner image is transferred to the paper by giving a positive charge to the back of the paper.

Page 46: Potential Control
PROCESS CONTROL 30 July, 1999 (Revised) 2.1.2 POTENTIAL CONTROL Overview Potential control is the process of controlling the development potential to maintain the density of the toner image on the drum. It does this by compensating for variations in drum chargeability and toner chargeability. The machine uses the image density (ID) sensor to measure drum reflectivity and the density of a standard sensor pattern.
Page 47 30 March, 1999 PROCESS CONTROL (2) Initial Process Control Self Check The initial process control starts automatically when the power is turned on (or when the machine returns to standby mode from sleep mode), but only if the hot roller in the fusing unit is less than 100 degrees centigrade. This process control is done only when SP3-125 (Set Potential Control Method) is set to "0 (Auto)."...

After the process control, the proper values for V have been defined for the maximum laser power. However, the medium (greyscale) range is ignored. To improve this situation, a new process called ‘process control gamma correction’...

30 March, 1999 PROCESS CONTROL Process control γ target is stored in the NV-RAM on the main control board. The CPU calculates the process control γ on the main board. The results of process control γ calculation go to the LD main control board to compensate the LD input data.

Page 51: Step 1: Vsg Adjustment
30 March, 1999 PROCESS CONTROL Step 1: V Adjustment The type of ID sensor used in this machine responds differently for black and color, so there are two V values, one for black toner and one for CMY toner. The type of ID sensor used in this machine is very sensitive, and outputs some voltage even if there is no light being reflected off the drum.
Page 52: Step 3: Sensor Pattern Potential Detection
PROCESS CONTROL 30 March, 1999 Step 3: Sensor Pattern Potential Detection Process The drum potential sensor detects the potential on each grade of the 16-grade sensor pattern latent image, for each color, and the output is stored in memory. Feedback Type Drum potential Sensor Feedback circuit A269D053.WMF This copier uses a feedback drum potential sensor.
Page 53: Step 4: Sensor Pattern Density Detection
30 March, 1999 PROCESS CONTROL Step 4: Sensor Pattern Density Detection Process The development rollers of the respective colors develop the sensor pattern latent images for K, Y, C, and M generated in Step (2). In Step (4), the ID sensor detects the densities of the 16 patch patterns for each color.
Page 54 PROCESS CONTROL 30 March, 1999 Figure A shows the relationship between the output of the normal reflection ID sensor and the amount of Y, C, or M toner attached to the drum. This shows that the ID sensor output (Vsp) results from not only the light reflected from the toner but also the component of light reflected from the drum.
Page 55: Step 5: Toner Amount Calculation
30 July, 1999 (Revised) PROCESS CONTROL Step 5: Toner Amount Calculation The amount of toner on the drum (M/A, mass per unit area, mg/cm ) is calculated for each of the 16 grades of the sensor pattern from the ID sensor output value (Vsp) from each grade of the pattern.
Page 56: Step 7: Selecting The Optimum Vd, Vb, Vl
PROCESS CONTROL 30 March, 1999 Step 7: Selecting the Optimum V The machine now adjusts V , and V to try to bring the development potential to the ideal value. To do this, it uses a pointer table. This is a look-up table in ROM of V against V , and V...
Page 57: Toner Supply Control
30 March, 1999 PROCESS CONTROL 2.1.5 TONER SUPPLY CONTROL This machine uses fuzzy logic to control the amount of toner supplied to the development unit so that the development capacity does not fluctuate due to toner consumption, toner supply, agitation, or extended periods of nonuse. This control is accomplished using the sense data from the drum potential sensor, toner end sensor, ID sensor, and TD sensor.
Page 58: Td Sensor Output
PROCESS CONTROL 30 March, 1999 TD Sensor Output The relationship between the TD sensor output Vt and the toner density in the developer is shown in the figure on the right. The target toner density of this copier is 5 WT%. The TD sensor output for this toner density is referred to as Vref.
Page 59: Calculating The Amount Of Toner On The Drum
30 March, 1999 PROCESS CONTROL Calculating the Amount of Toner on the Drum The target for the ID sensor pattern is 0.7 mg/cm for the C, M, and Y toners and 0.3 mg/cm for the K toner. For the procedure to calculate the amount of toner on the drum, see Step 4, “Sensor Pattern Density Detection,”...

Page 63: Charge Corona Unit
30 March, 1999 DRUM UNIT 2.2.3 CHARGE CORONA UNIT A269D204.WMF This copier uses a single wire scorotron system to charge the drum. The output of the charge high voltage power supply is -6 kV. A grid keeps the surface potential of the drum at –670 V (standard value). The grid bias voltage is corrected so that the surface potential remains constant by sensing the surface potential of the drum with the drum potential sensor.

30 March, 1999 SCANNER UNIT 2.3 SCANNER UNIT 2.3.1 OVERVIEW A269D001.WMF An image of the original illuminated by the exposure lamp [A] (a halogen lamp) is reflected onto a color CCD [B] (Charge Coupled Device) via the 1st [C], 2nd [D], and 3rd [E] mirrors, filter, and lens [F].
Page 68: Scanner
SCANNER UNIT 30 March, 1999 2.3.2 SCANNER A269D001.WMF The 1st scanner consists of the exposure lamp [A], main and sub reflectors [B], and 1st mirror [C]. This model uses a halogen lamp with ten elements. The frosted surface of the exposure lamp ensures even exposure in the main scan direction. The exposure lamp is energized by a dc supply to avoid uneven light intensity caused by power fluctuations while the 1st scanner moves in the sub-scan direction.
Page 69: Scanner Drive
30 March, 1999 SCANNER UNIT 2.3.3 SCANNER DRIVE A269D002.WMF A five-phase stepper motor [A] drives the scanner. This motor drives the 1st [B] and 2nd [C] scanners via two scanner wires. The wires at the front side and the rear side are the same. In full size mode, the 1st scanner speed is 200 mm/s during scanning, and 1,200 mm/s when the scanner returns.

30 March, 1999 IMAGE PROCESSING ACS (Auto Color Selection) A269D076.WMF A269D075.WMF The auto color selection function determines if an original is black/white or color. Then black copy mode or full color mode is automatically selected to match the original. To recognize if the original has a color area or not, the RGB video signals are compared.
Page 84: Automatic Original Type Selection
IMAGE PROCESSING 30 March, 1999 Automatic Original Type Selection If this function is selected, the copier starts a pre-scan when the Start key is pressed. During the pre-scan, the copier detects two or more image features and identifies the type of original. Since the copier selects the mode that is most suited to the original, the selected mode does not always match the specified mode.
Page 85: Image Separation
30 March, 1999 IMAGE PROCESSING Image Separation The copier senses and separates the original image into text and photo (dot screen) areas. Generally, The text areas feature an appreciable difference in contrast between the background and image parts. The photo (dot screen) areas feature many intermediate levels of gradation.

Page 280: Squareness Adjustment
30 March 1999 LASER OPTICS SECTION 6.8.4 SQUARENESS ADJUSTMENT The purpose of this adjustment is to finely adjust the obliqueness of the image that is caused by the laser unit. NOTE: This procedure is used to finely adjust the inclination of the lines in the horizontal direction (horizontal lines) in the image by turning the laser unit and therefore tilting the scanning line of the laser beam.

In this case, turn the unit counterclockwise. Amount of inclination: The amount of inclination of the lines in the horizontal scanning direction in the image is almost proportional to the angle by which the optical housing unit is turned.
