4. REMOVAL OF DARK BOX COVER DURING TRANSPORTATION
5. PREVENTION OF BLUR IN COPY EDGE
6. LIGHT LEAKAGE FROM AE HOLDER OF OPTICAL UNIT
1. Change to 2/3 mirror and 4/5 mirror lock screw (to make removing it easier)
No. : SP-1873
2.General: To remove screws fixing the 2/3 mirror and the 4/5 mirror easier, we have improved them that

3.Action: From mid-October 1994 production
2. Improvement of insulation in dehumidification heater in optical unit
2.General: When the CL lead ground terminal of the light source unit was fixed near the dehumidification heater terminal as shown in below illustration, insulation between these two terminals become imperfect. We have changed the dehumidification heater tube to longer one.

3.Action: From the first unit of February 1995 production
3. Prevention of dark box contacting dehumidification heater during wearing or taking off it
2.General: The market and Xerox Co., Ltd. pointed that the dark box cover may contact the dehumidification heater terminals when it is worn or taken off. We have attached the insulation sheet to the dark box cover inside to make insulation perfect.

Attach its inside to match the metal plate edge.
3.Action: From mid-October 1994 production
4. Removal of dark box cover during transportation
2.General: The removal of dark box from the optical unit occurred during transportation.
3.Description: (1) We have changed one of three screws
which fix the lens unit (shown in right) to the step screw. This is made to prevent the dark box removal. (SF-2014, Z-800 only)
(Change to the step screw)

(2) Part A of the dark box cover (shown in
right) has been exactly brought to the side frame on the paper feeder. This is made to fix it without blur and to prevent removal. (SF-2114/2214, SN1420/1430 only)
4.Action: From mid-December 1994 production
5. Prevention of blur in copy edge
2.General: The pulley attachment plate R inside the 2/3 mirror unit contacted screws which attached wire fixing plate inside the light source unit during the machine production. This caused blur on the copy edge. We have changed the screw length to prevent this.
3.Description: We have changed the screws shown in below illustration to the shorter things. (both rear and front frame sides)
(Current) (New)
XBPSD40P08K00 (M4x8) XBPSD40P06K00 (M4x6)
Contact
* The height of the drive pulley
attachment plate R depends on the MB-B rail adjustment.
No need to correct the parts guide because the M4X6 size screw parts’ code has already described.
4.Action: From the first unit of November 1994 production

6. Light leakage from AE holder of optical unit
2.General: Light of the light source unit leaked from the AE holder of the optical unit during the machine production. This influenced to the half tone copying. We have attached a cover to the AE holder to prevent this.
There is no problem in the characters copying or black solid copying.
