Request for correction of Technical Report (DTE-309)

1. Model Name: SD-2060/2260/3062

2. General: Since there are some error in the description and illustration of "Subject: Countermeasure

against trouble in 2000/3000 tray unit" of Technical Report (DTJ-312/DTE-309) already issued,

No. : DTE-354

correct them as shown below.

3. Changes of 2000/3000 tray unit

1. Model Name: SD-2060/2260/3062

2. General: To improve the noise from 3000 tray unit (SD-2260) and breakage of actuator at the lower limit,

the following countermeasures are taken. The vendor of the M sensor plate is also changed to
improve the productivity.

1. Countermeasure against abnormal noise during operation of 3000 tray
Since the noise results from the precision variation of the dimension of 30T gear, it is changed
to one whose dimensional precision is improved. It is added that grease is coated on the
bearing of the plate on which the lift motor is installed.

2. Countermeasure against lower limit actuator
When the 3000 tray lowers to the lower limit, the tray lever blocks the photo sensor as
shown below. If the 200 bottom plate and tray lever comes into contact at the area A as
shown below, the tray lever may be broken. Therefore, the dimension of the area B shown
below is made to be 1 mm shorter than that of the existing one.

3. Change of M sensor plate and part vendor
For better productivity, the part vendor of the M sensor plate is changed. Accordingly, the
part code is changed.2/3
