SHARP LPE173 Technical Report

Date: Sep. 30, 1993

LASER PRINTER : JX-9600 SERIES

No. : LPE-173

ADDITION AND ELIMINATION OF PARTS

1. Improved EMI levels

1.Model name: JX-9600/JX-9600PS 200V Series

2.General: To improve EMI levels, conductive tape and three capacitors have been added.

➀ Addition of conductive tape

To provide adequate EMI margins, the AC earth plate and the sensor earth plate have
been connected with conductive tape (12.5 x 120 mm).

➁ Addition of two 100pF capacitors and one 39pF capacitor to the ICU board

<<ICU board solder side CN 505 area>>

Add a 39pF ceramic
capacitor between the
CN 505 4A and 6B pins.
<Note>
Add an Irax tube to the
pin 4A capacitor pin

Cautions when attaching

1. Make the capacitor pin as
small as possible

2. Make sure no other pins or
parts are touched

Add 100pF ceramic capacitors between CN 505 pins 4A and 6A
Add 100pF ceramic capacitors between CN 505 pins 10A and 10B
