1. Preventing LCD control PWB and transistor (Q204) breakdown.
1.Model Name: SF-2035
2.General: If the connection between the LCD control PWB and LCD is incomplete (incomplete
connector lock), excessive current may flow to the transistor (Q204) in the LCD
controller PWB, causing damage. For this reason, the machine is being modified as
indicated below:
3.Description: We are changing the circuitry in the communication data line. We are also changing the
transistor (Q204) and adding a resistor.

2. Creation of a 500 cassette paper supply unit replacement part kit.
1.Model Name: SF-2022/2027/2035
2.General: In order to improve serviceability, we have created a kit including the paper feeding unit
replacement parts discussed in TR SP-2004. Furthermore, in the first paper feeding
units, reinforcement boards (LPLTM4057FCZZ) were not always installed. They will be
included in the replacement kits.
