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 power 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 (the Start key starts blinking red and green alternatively), 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. Never operate the copier without the ozone filters installed.

2. Always replace the ozone filters with the specified ones at the specified intervals.

3. 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 NVRAM on the system control board has a lithium battery which can explode if replaced incorrectly. Replace the NVRAM only with an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge or burn this battery. Used NVRAM must be handled in accordance with local regulations.

1. SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an 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.

4. When keeping used lithium batteries in or der 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.

LASER SAFETY

The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and laser subsystems to the factory or service depot when replacement of the optical subsystem is required.

WARNING Use of controls, or adjustment, or performance of procedures other than those specified in this manual may result in hazardous radiation exposure.

WARNING Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser beams can seriously damage your eyes.

NOTE: 1) The tables indicate the copy paper size for each original for 50 to 200 %

zoom ratios.

2) After specifying a zoom ratio, APS automatically selects a paper size if there is an equivalent paper size available, that guarantees the quality of the magnified copy image.

3) If there is no paper that corresponds to the detected size, the machine displays the message "Set xx paper in tray" and stops the job (copying is still possible).

4) For "—" in the above tables, the machine displays the message "Cannot detect original size" and stops the job (copying is still p ossible). The selected paper feed tray does not change.

5) When less than 49% or more than 201% is selected, APS behaves in accordance with note 4 above.

6) APS also supports the by-pass feed table (except for non-standard paper sizes). When the paper size selected by APS can only be fed from the by-pass feed table, the machine displays a warning to instruct the user to use the by-pass feed table.

7) APS does not support A6, B6, and A5.

28 August, 2000 MECHANISM OVERVIEW

(1) Drum Charge

The charge corona applies a negative charge to the OPC drum and the charge grid ensures that this charge is even.

- B017/018 -

• A new charge corona cleaner was adopted to keep the charge wire and charge grid clean. The cleaner starts automatically when the main switch is turned on and if the fusing temperature is less than 100oC.

(2) Quenching

After cleaning, the OPC is fully exposed to light from an array of red LEDs, which quench the residual charge on the OPC drum in preparation for the next copy cycle.

(3) Drum Cleaning

The cleaning brush increases drum cleaning efficiency by applying lubricant to the OPC drum. The cleaning blade scrapes the residual toner off the OPC drum.

Overall

Information

(4) PCC (Pre-cleaning Corona)

The PCC lowers the charge on the photoconductor drum by applying AC and negative DC to improve the efficacy of the cleaning brush.

(5) Belt Transfer

Positive charge applied to the back of the transfer belt transfers the toner image on the OPC drum to the transfer belt.

- B017/018 -

• The electrical resistance of the belt varies from belt to belt and directly influences the image transfer belt bias. To optimize the image transfer belt bias a Current Feedback System was adopted to correct the current fluctuation caused by the variation of the electrical resistance on the belt.

• Another solenoid was added to the image transfer belt unit to keep the belt away from the drum between copy jobs. This helps prevent drum fatigue from residual voltage on the belt.

1-11

MECHANISM OVERVIEW 28 August, 2000

(6) Paper Transfer

The negatively charged toner image is transferred to the paper by giving a positive charge to the back of the paper while the paper and transfer belt are held in close contact.

- B017/018 -

• A brush was added to the image transfer belt unit to help push the belt down. This enables toner on the transfer belt to transfer onto the paper before the electrical field between the transfer belt and roller affects it. This helps to decrease the amount of scattered toner on printouts.

(7) Paper Separation Corona

After transfer, the separation corona quenches the negative charge on the paper to reduce the attraction between the belt and paper. The curvature of the belt causes the paper to separate from the transfer belt.

(8) Belt Cleaning Unit and Lubricant Application Brush

The brush applies lubricant, which makes it easier for the belt cleaning blade to scrape excess toner off the transfer belt.

(9) ID Sensor

The ID sensor detects the density of the sensor patches developed on the OPC drum. The signal from the ID sensor is used for process and toner supply control.

- B017/018 -

• A thermistor has been added to the ID sensor board. The thermistor corrects the output from the ID sensor depending on the temperature. This supplies more reliable data for better toner density control.

(10) Development

The latent image on the drum attracts the negatively charged toner. Toner is preferentially attracted to those places on the drum surface where the laser reduced the negative charge. The development units for each color are included in the revolver unit.

- B017/018 -

• A High frequency alternating current is applied to the development bias to optimize development. This improves the quality of grainy images.

1-12

28 August, 2000 MECHANISM OVERVIEW

(11) Potential Sensor

The potential sensor detects the electrical potential (the strength of the electric field) on the photoconductor dru m for process contr ol .

(12) Laser Exposure

The polygon mirror reflects the laser beam emitted from the laser diode and projects it onto the drum through the f-theta lens, drum mirror, and toner shield glass. The intensity of the laser output varies in correspondence with the image data. This process creates the latent image on the drum.

- B017/018 -

• The laser power was adjusted to achieve uniform side-to-side laser power. This causes the laser power to be applied evenly across the drum surface.

• Pulse positioning control was adopted to make the image appear smoother.
