SHARP DTE206 Technical Report
Date: Jul. 19, 1995
DUPLICATOR: SD-2060
1. CHANGE IN THE METHOD OF SIGNAL COUNTING FOR THE SF-EA11 ATTACHMENT OPERATIONS.
2. MEASURES TO PREVENT CONTACT OF THE 1000 TRAY SIZE GUIDE TO IMPROVE PRODUCTIVITY.
3. MEASURES TO PREVENT THE FIXING SCRAPER FROM WARPING DUE TO THERMAL EXPANSION.
4. MEASURES TO PREVENT STACKING DURING OFFSET MODE OPER ATIONS.
5. CHANGE IN THE MATERIAL USED FOR THE WASTE TONER BOTTLE.
No. : DTE-206
1. Change in the method of signal counting for the SF-EA11 attachment operations.
1.Model name: SD-3062
2.General: In order to carry out the change of the signal counting method during SF-EA11
(card-type section management counter) attachment operations, the program content of
the ROM program of the IC in the operations control PWB has been changed.
3.Description: ROM Version no.: V4.01 → V4.02
4.Action: From the start of 1995 January production.
2. Measures to prevent contact of the 1000 tray size guide to improve productivity.
1.Model name: SD-2060/3062
2.General: There is insufficient room between the connector for the sensor attached underneath
the air paper feeder unit and the R size guide in the 1000 tray unit, and therefore there
is a danger of the two coming in contact with each other. To alleviate this problem, the
shape of the R size guide has been changed.
3.Description: Change to prevent contact:
(1) Change in the shape of the 1000 R size guide.
Change to improve productivity:
(2) Change of the 1000 F size guide.
(3) Discontiuence of the SG spacer boss.
(4) Change in the attachment screws of the 1000 FN size guide.
(5) Change in the 1000 F size guide (Changed to the same item as the 1000 R size
guide).
4.Action: From the start of 1995 January production.

3. Measures to prevent the fixing scraper from warping due to thermal expansion.
1.Model name: SD-2060/3062
2.General: The supplementary CL scraper in the fusing unit sometimes warps due to thermal
expansion, causing the center portion of the scraper to raise up slightly. To alleviate
this problem, the following measures have been taken.
3.Description: To disperse the thermal expansion effects, the method of attachment has been changed
by changing the attachment holes (screw holes) of the supplementary CL scraper to
long holes, and changing the screws to step screws.
4.Action: From 1995 Mid-February production.
4. Measures to prevent stacking during offset mode operations.
1.Model name: SD-3062
2.General: When high humidity adsorption copy paper is used and copy operations are carried out
in the offset mode, stacking does not always occur as efficiently as it should.
To improve this problem, the following measures have been taken.
3.Description: (1) A shift roller sheet has been attached to the staple tray (P/G no. 52 -45).

Caution:
1. Be sure to wipe the attachment surface of the
sheet with alcohol before attaching the sheet.
2. The sheet should be attached so that the vertical
direction attachment standard for the F/R N shift
roller is 7±1 from the cutaway of the metal plate,
and the horizontal direction standard should be
such that the riding surface is aligned with P.
3. After assembly, the F/R N shift roller should be
used by collecting the edge of the sheet in the
elevator frame cover as shown in the figure above.

In accordance with the changes described above the previously attached shift roller
sheet (as shown in the figure to the right) has been discontinued.
