Bulletin Cross Reference Ricoh Group Companies Last Bulletin No. Gestetner N/A Ricoh 015 Savin N/A SUBJECT: SPRING REPLACEMENT - CHARGE CORONA UNIT SYMPTOM: Difficulty when replacing Charge Corona Wires. CAUSE: The angle of the opening on the Spring is only 45°, and this makes it difficult to attach the spring. Also the notch in the Right End Block made it difficult to attach the Spring from above. SOLUTION: The angle on the opening of the Spring has been changed from 45° to 90° so the Spring can be replaced with less pulling. Also the length of the notch in the Right End Block has been changed from 4 mm to 2.9 mm so the spring end with a diameter of 3 mm can be hooked from above. See the Before and After figures below.
