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 the optional tray heater and the optional anti-condensation heaters 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. 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.

SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL

1. Do not incinerate toner cartridges or used toner. Toner dust may ignite suddenly when exposed to open flame.

2. Dispose of used toner, developer, and organic photoconductors in accordance with local regulations. (These are non-toxic supplies.)

3. Dispose of replaced parts in accordance with local regulations.

6.1 OVERVIEW

[E]

[D]

[B]

[F]

[C]

[G]

A245D500.wmf

There are two paper trays and a by-pass feed table [A]. The upper [B] and lower [C] paper trays each hold 250 sheets. The by-pass

feed table can hold 1, 10, or 80 sheets of paper, depending on the paper type. The semicircular feed rollers [D] drive the top sheet of paper from the tray to

the registration rollers [E] through the relay rollers [F]. The tray has two corner separators (see [F] in the diagram in the "Paper Lift

Mechanism" section), which allow only one sheet to feed at a time. The corner separators, along with the tray’s springs, also serve to set the height of the paper stack.

When the tray is closed after the paper is loaded, the paper size actuator located at the front right of the tray pushes the paper size sensor. This informs the cpu what paper size is loaded in the tray and that the tray is in place.

The by-pass feed table uses a feed roller and friction pad system to feed the top sheet of paper to the registration rollers.

In humid environments, copy paper may crease as it comes out of the fusing unit. The optional tray heaters [G] are available as service parts to keep copy paper dry. It can be installed for both paper trays.

When the paper tray [A] is closed after paper is loaded, the release slider [B], which is mounted on the bottom part of the tray, is pushed by the projection [C] on the main frame and the release slider comes off the bottom plate hook [D].

Copier

Once the release slider comes off, the bottom plate is raised by the pressure springs [E] and the top sheet pushes up the corner separators [F]. This keeps the stack of paper at the correct height.

[G]

A245D503.wmf

Through several gears and a timing belt, main motor rotation is transmitted to the tray paper feed clutch gear [A] and the relay roller clutch gear [B].

-Feed rollers-

The tray paper feed clutch gear is on the same shaft as the semicircular feed rollers [C]. After the

key is pressed, the tray paper feed clutch [D] is energized for 250 milliseconds to release the stopper [E]. Then main motor drive is transmitted, and the feed rollers make one complete rotation to feed the top sheet of paper, which is enough for the leading edge of the paper to be caught by the relay rollers [F]. The feed rollers stop when the stopper drops back into the notch at the end of one complete turn.

-Relay rollers-

The relay roller clutch gear is on the same shaft as the relay rollers. The rotation timing of the relay rollers is controlled by the relay roller clutch [G]. The CPU energizes the relay roller clutch after the

key is pressed (at the same time as the tray paper feed clutch). Paper is fed from the relay rollers to the registration rollers.

The registration sensor and the exit sensor are used for misfeed detection. If the CPU detects a misfeed, the Check Paper Path and the Location indicators turn on.

Copier

Just after the main switch is turned on, the CPU checks these sensors for any jammed paper.

During the copy cycle, the CPU performs four kinds of misfeed detection. The following explains jam detection timing for copying on A4 sideways paper from the upper paper tray unit.

(1): Checks whether the registration sensor is actuated within 2.05

seconds after the main motor starts rotating.

(2): Checks whether the exit sensor is actuated within 4.48 seconds after

the main motor starts rotating.

(3): Checks whether the copy paper has passed through the registration

sensor 6.50 seconds after the main motor starts rotating.

(4): Checks whether the copy paper has passed through the exit sensor

6.78 seconds after the main motor starts rotating.

IMAGE FUSING 26 September 1997

7. IMAGE FUSING

1. Both the hot roller and pressure roller for the A245 are different from the

A219. To distinguish between the two types of roller, check the end of the roller shaft as described below.

A245D505.wmf

A245D506.wmf

A245D507.wmf

2. Due to the increase in copier CPM, the thickness of the metal core of the

hot roller has been increased for the A245 copier. This causes the ready temperature to be higher, and the temperatures are as follows:

A245 copier A219 copier

172°C: 120 V machines 165°C: 120 V machines 177°C: 230 V machines 172°C: 230 V machines

Also, to achieve the same warm-up time as for the A219 copier in the 230 V machines, the fusing lamp wattage has been increased from 650 W to 760 W. For the 120 V machine, the warm-up time specification is slightly longer than for the A219, so the lamp is not changed.

3. FUSING IDLING (SP116)

Fusing idling can be selected with SP116. This mode should be used when the copier has fusing problems with copies which are made soon after warm up. This problem is most likely to occur in low temperature locations where the wall outlet condition is also not stable. Please note that when this mode is selected, copier warm-up will take a couple of seconds extra, and the first copy time will not be within specification. When the start key is pressed, fusing idling is performed for 2 seconds. If the temperature of the fusing unit is below the operating temperature by up to 10°C, copying starts. If the detected temperature is more than 10°C lower than the operating temperature, fusing idling will continue until the

detected temperature reaches 180°C. This will take 6 ~ 7 seconds longer to warm up than if fusing idling is not used.
