IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the copier and peripherals,
make sure that the copier power cord is unplugged.
2. The wall outlet should be near the copier and easily accessible.
3. Note that some components of the copier and the paper tray unit are
supplied with electrical voltage even if the main switch is turned off.
4. If any adjustment or operation check has to be made with exterior
covers off or open while the main switch is turned on, keep hands away
from electrified or mechanically driven components.
5. If the start key is pressed before the copier completes the warm-up
period, keep hands away from the mechanical and the electrical
components as the copier starts making copies as soon as the warm-up
period is completed.
6. The inside and the metal parts of the fusing unit become extremely hot
while the copier is operating. Be careful to avoid touching those
components with your bare hands.
HEALTH SAFETY CONDITIONS
1. Toner and developer are non-toxic, but if you get either of them in your
eyes by accident, it may cause temporary eye discomfort. Try to remove
with eye drops or flush with water as first aid. If unsuccessful, get
medical attention.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
1. The copier and its peripherals must be installed and maintained by a
customer service representative who has completed the training course
on those models.
2. The RAM board on the main control board has a lithium battery which
can explode if replaced incorrectly. Replace the battery only with an
identical one. The manufacturer recommends replacing the entire RAM
board. Do not recharge or burn this battery. Used batteries must be
handled in accordance with local regulations.

  • Page 23: Paper Feed And Registration

    PAPER FEED AND REGISTRATION 13 October 1997 9. PAPER FEED AND REGISTRATION 9.1 OVERVIEW A212D503.wmf The paper feed station uses a paper tray [A] which can hold 500 sheets. The paper tray uses semicircular feed rollers [B] and a corner separator. The semicircular feed rollers make one rotation to drive the top sheet of the paper stack to the relay rollers [C].

  • Page 24: Paper Tray Feed

    13 October 1997 PAPER FEED AND REGISTRATION 9.2 PAPER TRAY FEED 9.2.1 Paper Lift Mechanism A212D501.wmf The capacity of this tray is greater than usual for a corner separator type. Because of this, there are two springs to lift the bottom plate. As the tray is pushed into the machine, shutter [A] under the tray pushes against projection [B].
  • Page 25 PAPER FEED AND REGISTRATION 13 October 1997 A212D504.wmf The paper tray capacity has been increased from 250 to 500 sheets and the paper lift mechanism differs from former one. Force is applied to the bottom plate by the main lift spring and the secondary lift spring, depending on the amount of paper remaining in the tray.
  • Page 26 13 October 1997 PAPER FEED AND REGISTRATION 9.3 Corner Separator Over Rising Prevention Mechanism A212D505.wmf A212D506.wmf The bottom plate stopper [A] prevents the corner separator from rising too high. When the tip of bottom plate stopper touches the bottom plate by the weight of stopper itself, point [B] on the bottom plate stopper contacts [C] on the corner separator.
  • Page 27 PAPER FEED AND REGISTRATION 13 October 1997 9.4 Corner Separator Stopper Mechanism A212D502.wmf The corner separator stopper prevents the corner separator from dislocation when the tray holds a lot of paper. When the paper tray is pushed into the machine, the stopper holder [A] slides to press the corner separator stopper [B] down.
