1. Countermeasure against dirty MC
2. Better productivity of lower main harness
3. Better performance of ADU paper supply
1. Countermeasure against dirty MC
1. Model Name: SF-2050/2052/2150
No. : SP-2254
2. General: As the countermeasure against flying toner on the above models, the side molt and side seal
in the process unit are changed in the shape.

(2) The side seals F/R are abolished, and the side seals FHP/RHP are added.
(3) The rear molt HP is newly provided.
4. Action: SF-2050 1st product in November, 1997
SF-2052 1st product in October, 1997
2. Better productivity of lower main harness
1. Model Name: SF-2052/2150
2. General: The HP main harness R of the above models is provided with the core. Whether the cables
are passed through the core or not passed, the same colored cables are used. For better
productivity, the cable colors are changed. However, the part codes are not changed along
with the change.
3. Description:
4. Action:
Gray cable passed through the core → Kept as it is
Gray cable not passed through the core
Pink cable passed through the core → Brown
→
Pink
SEC → Running change during production of December, 1997
SEEG → Running change during production of January, 1998
3. Better performance of ADU paper supply
1. Model Name: SF-2050/2052/2150
2. General: The following change is applied to improve the paper supply function in ADU of the above
models.
3. Description: (1) Change of height of rib of paper supply
guide (1 → 2 mm) → If the rib is short,

the releasing plate may be incompletely
installed.
(2) In order to increase the durability of the
ADU paper supply roller and reverse
roller, the material is changed. NX220
(yellow) → NS-S1 (gray)
(3) Since the wind of the ADU cooling fan is directly blown to the paper in ADU, the resup-
plied paper may be jammed. Therefore, the ADU guide sheet is added.
(4) Since the spring pin in the drive plate unit may be broken, the material is changed.
→ SUS (sliver) → Iron (black)
(5) Since the ADU retaining sheet is resistive during supply of ADU, the supplied paper may
be jammed. Therefore, the shape is changed to increase the margin.
(6) As the countermeasure against WF during paper resupply of ADU, the load of the fulcrum
spring is changed. (325 g (silver color) → 375 g (black color)) However, along with the
change, the part code is not changed.
(7) In order to eliminate static electricity in ADU, the ADU brake ground is added.
4. Action:
(1)∼(6) SF/2050/2052/2150 1st product in October, 1997
(7) SF-2052/2150 1st product in October, 1997
SF-2050 1st product in November, 1997
