SHARP DTE218 Technical Report

Date: Nov. 30, 1995

DUPLICATOR : SD-2060

1. MEASURE TO IMPROVE THE FUSE BURN-OUT MARGIN OF THE
FUSES IN THE POWER SUPPLY PWB.

2. MEASURE TO PREVENT CONTACT WITH THE PWB ELEMENTS

3. MEASURE TO PREVENT CRACKING OF THE ADIABATIC
BUSHING OF THE FUSING UNIT.

4. CHANGE IN BEARINGS TO IMPROVE PRODUCTIVITY.

No. : DTE-218

1. Measure to improve the fuse burn-out margin of the fuses in the power supply PWB.

1.Model name: SD-2060/3062 (only for machines in the 100 V series).

2.General: To improve the DC power supply PWB fuse burn-out margin in machines bound for the

Japanese domestic market, a change in fuses F710 and F703 was carried out. The
change that was carried out in machines bound for the Japanese domestic market also
complied with standards in the overseas markets, and as a result, the change has also
been carried out on fuses in machines bound for overseas markets.
In accordance with the change described above, the parts code for the DC power
supply PWB has also been changed.

3.Description: F710: 3.15 A/125 V → 4.0 A/125 V .
F703: 4.0 A/125V → 5.0 A/125 V.

Note: The 5.0 A/125 V fuses used after the change described above has been carried
out is a newly established part, but the 4.0 A/125 V fuses previously used with fuse
F703 can be transferred for use with fuse F710.

4.Action: SD-2060 → From 1995 mid-July production.
SD-3062 → From 1995 mid-August production.

2. Measure to prevent contact with the PWB elements.

1.Model name: SD-3062

2.General: When installing the photo transistor in the paper detection sensor attachment plate

used in the finisher frame unit and the finisher gate frame unit, there is a possibility of
the photo transistor PWB elements coming in contact with the paper detection sensor
attachment plate. To alleviate this problem, the shape of the paper detection sensor
attachment plate has been changed.

3.Action: From the start of 1995 September production.

3. Measure to prevent cracking of the adiabatic bushing of the fusing unit.

1.Model name: SD-2060/3062

2.General: Cracking sometimes occurs in the adiabatic bushing used in the upper heat roller of the

fusing unit. To alleviate this problem, a change in the material of the bushing has been
carried out to strengthen it.

3.Action: From the start of 1995 December production.

4. Change in bearings to improve productivity.

1.Model name: SD-2060/3062

2.General: A change in the bearings used in the air paper feeding unit has been carried out to

improve productivity.

3.Action: From the start of 1995 December production.
