1. Use the foolowing cautions for the peripheral
installations:
• When you install the horizontal transport unit (LCT accessory) in the copier, while holding down the small white
roller of the upper left guide plate, tighten the lock lever assembly. Be sure that the lock lever bracket pushes down
the upper left guide plate when it is locked.
• Align the position of the LCT and finisher with the copier. This is to prevent paper misfeeds where the units connect.
For details, refer to their installation procedure explanations.
• The optical fiber cable connectors must be set to the sockets properly as they have the setting direction.
• The printer interface board, printer harness, 2 connector joint studs, and 4 nylon studs, which are the copier’s
accessories, are required for the printer connector unit installation.
9.2 Paper Feed Section
• Do not touch the feed, reverse, and pick-up roller surfaces with bare hands.
• Install the feed roller in the correct direction as it has a one-way clutch built-in.
• Because the torque limit pressure is properly adjusted, do not loosen the torque limiter stopper screws.
• Because the side-to-side registration adjustment mechanism is also provided on the original side (ADF and SADF), make
adjustments for each tray on the basis of the platen cover mode.
• When you adjust the leading edge or side-to-side registration, be sure to set the paper side guides of the paper tray
securely.
9.3 Optics Section
• Every 200K and at every visit, clean the exposure glass using glass cleaner or alcohol. Then wipe with silicon oil. Wiping
the exposure glass with silicon oil helps transport originals more smoothly and prevent original misfeeds caused by static
electricity. Wipe the mylar strips on the original transport path for the same reason.
• If the cooling air flow to the xenon lamp and flash power supply unit becomes low, the flash voltage step will exceed 28
earlier than normal. Be sure to clean the air filters every PM.
• Working near the lamp is dangerous. Never work near the lamp without turning off the main switch and waiting at least 1
minute for discharge.
• To avoid wiring problems of high voltage parts, never disassemble the connector going to the xenon lamp.
• Take care and check the position of the harness going to the xenon lamp.
• To avoid xenon lamp damage, firmly fit the xenon lamp connectors to the sockets. Push each connector end with your
fingers, then tighten two screws.
• Be sure to wire the three flash power source lines correctly, the white wire (from the trigger transformer), red line and black
line from the top. If wired incorrectly, the lamp may burn up.
• When reinstalling the xenon lamp in the unit, position the lamp exactly. If the position is not correct, the life time of the
lamp might be reduced. Insufficient light intensity will increase the lamp voltage repidly due to process control.
• Normally adjusting the uneven illuminance is prohibited. It seems difficult to return the illuminace to the original setting if
you change the position of the front and rear reflectors.
