No. : DTE-201

1. Change in tray lock roller. (For productivity enhancement)

1.Model name: SD-2060, 3062

2.General: The tray lock rollers used for the models listed above have been changed from a

ball-bearing type to a bushing-type to improve productivity.

3.Action: From the start of 1994 December production.

2. Trouble shooting warping of the operation section filter.

1.Model name: SD-2060, 3062

2.General: Filter A of the operation section sometimes warps, causing the filter to raise up.

To alleviate this problem the double-sided tape used for the filter has been changed to
one with stronger adhesion.

3.Action: From 1994 mid-December production (running change).

3. Trouble shooting manual stopper return malfunctioning and correction of
measurement errors of the regulation plate F/R bit section.

1.Model name: SD-3062

2.General: (1) Lack of space where the manual stopper rotating arm and the manual stopper arm fit

together when moving sometimes prevents the smooth operation of the two parts.
To alleviate this problem, the cut-away section of the manual stopper rotating arm has
been deepened by 1.5 mm.

(2) Measurement errors have occurred in the bit section of the regulation plate F/R in

the UDH regulation plate unit. To compensate for this problem a regulation plate rack
mylar was attached from the start of mass production, but now the problem itself has
been alleviated. In accordance with this change the regulation plates F/R from before
the measurement change will still require the rack mylar when used, but when
regulation plates F/R from after the measurement change are used the rack mylar will
no longer be necessary.
