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.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do not incinerate the toner bottle or the used toner. Toner dust may ignite suddenly when exposed to open flame. 2. Dispose of used toner, developer, and organic photoconductor according to local regulations. (These are non-toxic supplies.) 3. Dispose of replaced parts in accordance with local regulations. 4. When keeping used lithium batteries in order to dispose of them later, do not put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.

5.1 TEMPERATURE CORRECTION
A212D500.wmf
V Temperature correction has changed, as explained below. Also, the machine no longer performs drum rotation time correction. The new drum charge roller needs only about half the correction voltage that was needed in the base copier. Further, the level of correction needed for the lowest temperature point (5°C) is about the same as the normal room temperature point for the base copier [A]. In the base machine, rotation time correction was only needed for low temperatures where the temperature correction was large. In the new machines, the temperature correction is never greater than 300 V, so the rotation time correction has been eliminated.

9.1 OVERVIEW
[A] [C] [B]
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]. The paper tray has two corner separators, which allow only one sheet to feed. They also hold the paper stack. When the paper tray is drawn out of the machine, the spring pressure is released, and the tray bottom plate drops. In addition, there is no need to press the bottom plate down when putting the tray back in.

9.2.1 Paper Lift Mechanism [A] [C] [B] [H]
[G] [D] [F] [E]
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]. As the shutter slides past the projection, the shutter rotates, which forces the main lift spring [C] to pull the bottom plate lever [D]. The secondary lift spring [E] also pulls the bottom plate lever (this is described below). To apply spring tension for wider paper, projection [F] stops against the end of rail [G]. When this occurs, lever [H] swings out in the direction shown above, which stretches the spring as the tray is pushed in. The side fence position affects the orientation of [F]; wider paper causes [F] to contact [G] earlier, leading to greater spring tension when the tray has been pushed all the way in.

[A]
[B]
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. When one sheet remains in the tray, the bottom plate is supported only by the main lift spring. In this case, the secondary lift spring does not affect the bottom plate, because both ends [A], [B] of the secondary lift spring and the fulcrum of bottom plate lever line up in a straight line. As the amount of paper increases, the bottom plate lever inclines right, and tension for the both main lift spring and secondary lift spring increase.

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. This prevents the corner separator from over-rising. The shape of contact point [B] adjusts the distance between the corner separator and bottom plate according to the amount of paper.

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. The corner stopper holds down portion [C], immobilizing the corner separator. Damper [D] at the end of the right guide rail absorbs shock, when the tray is pushed in.
