Detailed SONY CFD980 Service Manual at an easy to find one stop shopping. Make my radio hobby technically interesting. Thanks.

Excellent service from Owner-Manuals.com, good prices and quick turn around. The supplied PDF was good enough quality to be enlarged sufficiently to read component values.

5. SERVICE REMARKS
5.1 Handling The Drum 1. Never touch the drum surface with bare hands. 2. Store the drum in a cool dry place. 3. Always wear gloves when cleaning the drum. 4. Prime the drum with setting powder only when the cleaning blade, cleaning brush, and drum are replaced as a set. 5. Never expose the drum to light for a long time. 6. Always keep the drum in the protective sleeve when inserting or pulling the drum out of the copier. 7. Drum conditioning is necessary when a new drum is installed. In addition, it should be done at the following times: a) When image density is reduced due to overexposure of the drum. b) After cleaning the drum. c) When the drum is lightly scratched. 8. Before inserting or sliding out the drum, the cleaning unit should be removed to avoid drum damage. When pulling out the cleaning unit, press the drum shaft slightly to the left. 9. Return used drums to the distributor according to standard procedure. 5.2 Charge Corona 1. Do not use emery paper to clean the corona wire; this abrades the wire coating. 2. Do not touch the corona wire with oily hands. Oil stains may cause white bands on copies. 3. The corona wire height should be adjusted only when a) the front end block is replaced. b) the drum charge current is uneven. 4. Make sure that the corona wires are correctly positioned between the cleaner pads. 5.3 Erase Lamp 1. A narrower lead edge erase margin increases the possibility of fusing jams. The margin should be at least 1.0 mm.
