[6] OPERATIONAL DESCRIPTIONS 1. Outline of operation The outline of operation is described referring to the basic configura- tion. (Basic configuration) Outline of copy operation A. Setting conditions: Operation panel • Set copy conditions such as the copy quantity and the copy den- sity with the operation section, and press the START key.
B. Basic structure of scanner section 1 Copy lamp (Xenon lamp) Generate photo energy to scan documents. 2 Reflector (Converging plate) Collects light emitted from the copy lamp and radiate the document. 3 No. 1 mirror Refracts the reflection light from the document to No.
Operation cycle B. Outline of print process The printer section of this machine employs the laser print system where print images are formed by the laser beams on the OPC drum. A high voltage (corona) is applied from the main charger to the OPC drum to charge the OPC drum.
(2) Exposure A Laser beam is generated from the semiconductor laser and control- led by the print pattern signal. The laser writes onto the OPC drum surface through the polygon mirrors and lens. The resistance of the OPC layer decreases for an area exposed by the laser beam (cor- responding to the print pattern signal).
(7) Optical discharge (Semiconductor laser) 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.
Makes the laser scanning speeds at both ends of the drum same as each other. B. Laser beam path a ≠ b ≠ c ab c d = e = f de f 5. Paper feed section A. Basic structure 1 No. 1 cassette paper feed roller (Semi-circular roller) Picks up paper from No.
(2) Manual paper feed tray operation Select the manual paper feed tray and press the START button, and the manual paper feed roller will be turned on to bring the paper feed roller in contact with paper and lift the shutter simultaneously.
[7] ADJUSTMENTS 1. Adjustment item list Section Adjustment item Adjustment procedure/SIM No. A Process section (1) Developing doctor gap adjustment Developing doctor gap adjustment (2) MG roller main .
5) Measure the distance from the marking position to the top of the doctor plate of the developing unit to insure that it is 18mm. If the distance is not within the specified range, loosen the fixing screw A of the main pole adjustment plate, and move the adjust- ment plate in the arrow direction to adjust.
value to 0. Make a copy (100%) again. 5) Set the laser radiation timing (image loss amount). Measure R in the figure below. Laser radiation timing = R (mm) × 10 6) Set the lead edge void. Measure H in the figure below. Lead edge void = H(mm) × 10 7) Enter the set value and press the start key.
(2) Main scanning direction (FR directional distortion balance adjustment) 1) Remove the OC glass and the right cabinet. 2) Loosen the copy lamp unit wire fixing screw. 3) Manually turn the mirror base drive pulley and bring No. 2/3 mirror base unit into contact with the positioning plate.
6) Put No. 2/3 mirror base unit on the positioning plate again, push the projections on the front frame side and the rear frame side of the copy lamp unit to the corner frame, and tighten the wire fixing screw.
1) Making of a test sheet Make test sheet by drawing parallel lines at 10mm from the both ends of A3 (11" x 17") white paper as shown below. (These lines must be correctly parallel to each other.) 2) Make a normal (100%) copy of the test sheet on A3 (11" x 17") paper.
