1.CLEANING IN HIGH HUMIDITY AND TEMPERATURE EN V I RONMENTS.
2.PREVENTION OF CONTACT WITH GEAR, SUCTION DUCT UNIT INSTALLATION SCREW.
3.PREVENTING TONER LEAKS FROM TONER HOPPER.
4.PREVENTING AUTO SHUTOFF OF THE DEHUMIDIFIER RESISTOR.
No. : SP-2032
1. Cleaning in high humidity and temperature environments.
1.Model Name: SF-2040
2.General: When successive copies are made in conditions of high humidity and temperature, the
used toner inside the DR cleaner unit may become clogged as a result of rising
temperature in the machine. This may result in poor cleaning. In response to this, we
are executing the following measures.
3.Description: We are adding a CL screw sheet below the DR frame to reduce dead space in the DR
cleaner unit.

Attach the CL screw sheet to
the bottom of the DR frame so
that the bend of the mylar fits
below the toner transport
propeller.
.
After attaching the CL screw sheet, fasten the toner receiver onto it with a screw.
(Attach the CL screw sheet after wiping the unit with alcohol. Attach it so that the
double sided tape is smooth.)

2. Prevention of contact with gear, suction duct unit installation screw .
1.Model Name: SF-2025/2030/2040
2.General: Because the main motor unit gear may come in contact with the tip of the screw
fastening the suction duct unit, we are changing to a shorter screw.
Change from M4 X 10 to M4 X 6 in the
3 places shown in the figure to the right.
3.Action: ∗ SF-2025 → From the middle of November, 1995 production.
SF-2030/2040 → From the first unit of November, 1995 production.
3. Preventing toner leaks from toner hopper.
1.Model Name: SF-2025/2030/2040
2.General: To prevent toner leaks developing in the corner and bearing, we are changing the molt
and adding parts.
3.Description: The figure shows newly added parts only. Refer to the part guide and part list for part
changes.

4.Action: Domestic (Japan) production → From the first unit of March, 1996 production.
China (SOCC) production. → From the first unit of May, 1996 production.
4. Preventing auto shutoff of the dehumidifier resistor.
1.Model Name: SF-2025/2030/2040
2.General: We are adding a DH relay PWB and changing the harness to enable the dehumidifier
resistor to work even during automatic shutoff mode.
Temporary measures will be taken for 100V versions from the first unit of May, 1996
production, and permanent measures will be taken for 200V versions from the first unit
of June, 1996 production.
