1.PREVENTING STRANGE NOISE WHEN TRAY IS RAISED.

2.SEPARATION ADJUSTMENT METHOD.

1. Preventing strange noise when tray is raised.

1.Model Name: SF-D23

2.General: A strange sound may come from the motor assembly when the tray is raised. For this

reason, we are making the changes listed below:

3.Description: A. Lengthening the shaft to prevent it from falling.
B. Bending the ends of the spring and hooking it onto the metal plate.
C. Change of gear material.

Furthermore, as a temporary measure, we are applying grease to the gear from the first
mass produced machine. In addition, since the parts making up the motor assembly are
not established as service parts, we are changing the motor assembly part codes.

4.Action: From the first unit of April, 1996 production.

2. Separation adjustment method. (Service information)

1.Model Name: SF-A14/15/16

We are changing the method for adjusting the SF-A14 ADF separation section as
follows.

Reason for change:

In the past, this adjustment was made by adjusting regular conveyance strength at
production or during servicing to between 350 and 400g. In this method, it is difficult to
measure from the paper supply pick roller side, and because of this difficulty there have
been cases of the conveyance strength being set to a rather low amount of 300 grams.
Originally, adjustment was made by the separation method (belt separation method),
using the amount of paper feed roller overlap. We are changing the from the regular
conveyance strength adjustment method to the separation adjustment method, which
sets the overlap of the separation belt.

Adjustment method for separation section:

➀ Measure and adjust the height (h) from the D guide to the separation holder.
➁ Adjust the screws with hexagonal holes at the front and back of the separation holder

so that “h” is between 1 1 and 12 mm. (At the same time, adjust so that the difference
in height between front and back is less than 0.5 mm.)
