DETAILS OF MODIFICATION
1. To facilitate servicing and assembing, the power pack has been changed so that it has been unnecessary to install the ferrite shield (#16070407, Ferrite Core) on the PCC Cable.(The fer rite shield has been used for the production machines from the first production to meet the VDE standards. )
2. To increase the margin against electrical noise, the material of the noise filter has bee n changed. NOTE: The old ferrite core is still available for servicing.

MODIFICATION BULLETIN NO. 4 Page 2 of 3 ISSUED ON: December 1, ’90
DETAILS OF MODIFICATION
On the production line, paper misfeeds occured in the inverter unit due to a wider than specified gap between the upper inverter roller (called " Return Drive Roller " in the service manual) and the left inverter guide (LT; A0584070, A4; A0584060).
* This was because the shape of the left inverter guide differed slightly from the design. To solve this problem, a modified upper inverter roller has been used for this lot. The diameter of this roller has been increased from 22.0 ± 0.2mm to 23.5 ± 0.2mm to decrease the gap mentioned above. Also, the roller is made of a new material to improve the durability. As the diameter of the rollers has been changed, the standard value of the return pinch roller solenoid adjustment has been changed. (See fig.3)
CAUTION: if you replace the left inverter guide (LT; A0584070, A4; A0584060), please replace the upper inverter roller with P/N 54464749 at the same time. If you replace the upper inverter roller only , install P/N A0589500.

If do this modification in the field without replacing the fusing roller stay, refer to RTB-F21-0 13.
2) A different type of M4 stepped screw is used to secure the oil supply felt. This ensures that t he felt absorbs oil better.
