1.REVENTION OF TC/AC CASE SOILING CAUSED BY IMPROPER GROUNDING.
2.ADDITION OF AIR SEALS TO PREVENT OF STAT IC NOISE EMITTED FROM THE NOISE INSULLATION DUCT .
3.CHANGE OF D TERMINAL GATE SOLENOID SCREWS TO PREVENT INTERNAL SHORT CIRCUITING OF THE SOLENOID.
4.HARNESS CLAMPS CHANGE TO IMPROVE OPERATING EFFICIENCY .
No. : DTE-098
1. Revention of TC/AC case soiling caused by improper grounding.
1.General: When the grounding spring malfunctions and no longer grounds the charged static electricity on the TC guide sheet AS (CSHEP3485FC01) plate of the TC/AC case unit, toner clings to the TC side charger wire and other parts. To remedy this problem, the grounding spring has been changed to a material with better conductivity.
2.Cause: To prevent soiling of the printing charger caused by poor grounding.
3.Description: The grounding spring has been changed to a material with better conductivity. In order
to distinguish between the old grounding springs and the new ones, the color of the springs has been changed from black to silver.
4.Effective time: (Factory action)
From June, 1993.

2. Addition of air seals to prevent of static noise emitted from the noise insullation duct.
1.General: To prevent static noise caused by air leaking from the noise insulation duct, an air seal has been added.
2.Cause: To prevent static noise emitted from the noise insulation duct.
3.Description: An air seal has been added to the boss on the back side frame extending from the
noise insulation duct opening.

3. Change of D terminal gate solenoid screws to prevent internal short circuiting of the solenoid.
1.General: There is no leeway between the ends of the screws fastening the D terminal gate solenoid and the solenoid coils. This poses the danger of the ends of the screws coming into contact with the solenoid. T o prevent this the length of the screws has been changed.
2.Description: The present screws being issued, M3 x 5 have been changed to M3 x 4.

3.Effective time: (Factory action)
From August, 1993.
4. Harness clamps change to improve operating efficiency.
1.General: The harness clamps have been changed for the reasons listed below.
2.Cause: To increase productivity in the production process.
3.Description: The harness clamps presently issued are too small, and there is a danger of wire
crimping when fastening the clamps with screws. To remedy this problem, the changes shown in the diagrams below have been implemented.
Changed harness clamp.
