[6] COPY PROCESS An OPC drum is used for the photoconductor. (Structure of the OPC drum layers) OPC layer (20 microns thick) Pigment layer (0.2 to 0.3 microns thick) Aluminum drum 1.
2. Outline of print process Step-2: Exposure (laser beam, lens) This printer is a non-impact printer that uses a semiconductor laser and electrostatic print process. This printer uses an OPC (Organic Photo Conductor) for its photoconductive material. First, voltage from the main corona unit charges the drum surface and a latent image is formed on the drum surface using a laser beam. This latent image forms a visible image on the drum surface when toner is applied.
Step-3: Developing (DC bias) Step-4: Transfer A bias potential is applied to the MG roller in the two component magnetic brush developing method, and the toner is charged negative through friction with the carrier. The visible image on the drum surface is transferred onto the print paper by applying a positive charge from the transfer corona to the backside of the print paper.
Step-7: Optical discharge (Semiconductor laser) Start Before the drum rotation is stopped, the semiconductor laser is radiated onto the drum to reduce the electrical resistance in the OPC layer and eliminate residual charge, providing a uniform state to the drum surface for the next page to be printed. 1) Because the grid potential is at a low level, the drum potential is at about -400V. (Carrier may not be attracted though the carrier is pulled towards the drum by the electrostatic force of 400V.

[9] ADJUSTMENTS 1. Optical section A. Copy magnification ratio adjustment The copy magnification ratio must be adjusted in the main scanning direction and in the sub scanning direction. To adjust, use SIM 48-1. (1) Outline 5) Calculate the main scanning direction magnification ratio. Main scanning direction magnification ratio = Copy image dimensions Original dimension X 100 (%) (When a 100mm scale is used as the original.
c. Adjustment procedure B. Image position adjustment 1) Set the scale on the document table as shown below. (Use a long scale for precise adjustment.) There are following eleven kinds of image position adjustments, which are made by laser control except for the image scan start position adjustment. For the adjustments, SIM 50-01 and 50-10 are used. No.
2) Execute SIM 50-01 3) Set the print start position (AE lamp ON) (A), the lead edge void amount (TEXT lamp ON) (B), and the scan start position (PHOTO lamp ON) (C) to 0, and make a copy of a scale at 100%. 4) Measure the image loss amount (R mm) of the scale image. Set C = 10 X R (mm). (Example: Set the value of C to 30.) When the value of C is increased by 10, the image loss is decreased by 1mm. (Default: 50) 5) Measure the distance (H mm) between the paper lead edge and the image print start position.
2. Copy density adjustment A. Copy density adjustment timing E. Copy density adjustment procedure The copy density adjustment must be performed in the following cases: Use SIM 46-1 to set the copy density for each copy mode. • When maintenance is performed. (1) • When the developing bias/grid bias voltage is adjusted. For selection of modes, use the [Exposure mode selector] key.
3) Make a copy. Check the adjustment level (shown in the above table) of the exposure test chart (Sharp Gray Scale). Sharp Gray Scale adjustment level Non toner save mode 1 2 3 4 5 6 7 8 9 10 W Note: • A digital multi meter with internal resistance of 1GΩ must be use for correct check. • The adjustment volume is locked, and no adjustment can be made. Procedures 1) Set the digital multi meter range to DC500V. Slightly copied. Not copied. Toner save mode B.
2) Set the test chart so that the scale is positioned as shown below, in the S-D mode and the D-S mode. Scale (S-D mode) Scale (D-S mode) (Adjustment procedure) (1) Paper trailing edge void quantity 1) Preparing test chart (Draw a scale at the rear end of one side of a sheet of A/4 white paper or letter paper) 2) Set the test chart on the document glass as shown below.

5. SPF scan position automatic adjustment 6. SPF mode sub scanning direction magnification ratio adjustment Place a A4 paper (white chart) so that it covers the SPF scan glass and the OC glass together, and close the SPF. Note: Before performing this adjustment, be sure to check that the OC mode adjustment in copying has been completed. When simulation 53-08 is executed, the current adjustment value is displayed as the initial display.
7. Automatic black level correction a. Cases when the adjustment is required 1) When the main PWB is replaced. 2) When the EEPROM in the main PWB is replaced. 3) When "U2" trouble occurs. 4) When repairing or replacing the optical section. b.
