SHARP DTE098 Technical Report

Date: Nov. 19, 1993

DUPLICATOR : SD-2060

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.
