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.

28 August, 2000 PROCESS CONTROL

2. DETAILED DESCRIPTION (B017/018)

2.1 PROCESS CONTROL

2.1.1 OVERVIEW

The process control for this machine is almost the same as for the A258/259/260 copiers. The only difference is in the potential values of VD (charge voltage), VL (laser power), and VB (developme nt bi as) . Thes e pot enti al val ues ar e optimized for 600 dpi processing. By changing the resolution, the density of the pattern used for process control has been changed. For process control to work properly, these potential values were changed from the A258/259/260 copier level to their current potential values for the B017/B018.

2.1.2 POTENTIAL CONTROL

Just like A258/259/260 copiers, there are 4 process control self-checks.

1) Forced process control self-check

2) Initial process control self-check

3) Interval process control self-check

4) Times process control self-check

Detailed

Descriptions

The different points on the process control self-check from A258/259/260 copiers are as follows.

Initial process control self-check

• The initial process control starts automatically when the power is turned on (or when the machine returns to stand- by mode fro m sle ep mo de) , but only if the fusing belt in the fusing unit is less than 550C. This is because the fusing belt temperature drops faster because the fusing belt is thinner than the hot roller.

TD auto correction (SP3-128)

• During the self-check, the machine automatically adjusts the toner concentration if the M/A (Mass/Area) of the ID sensor pattern is out of 4.0 +/- 0.05 mg/cm2, in order to attain proper image density. This mode is executed only when performing the interval process control self-check. (This was executed only when performing the initial process control self-check on A258/259/260 copiers.)

DRUM UNIT 28 August, 2000

2.2 DRUM UNIT

2.2.1 DRIVE MECHANISM

The drive mechanism for this machine is the same as for the A258/A259/A260 copiers. However, the drum shaft extends fully from the rear to the front side in order to prevent the photoconductor gap from fluctuating during drum rotation.

2.2.2 CHARGE CORONA UNIT CLEANER

A charge corona unit cleaner was adopted to prevent the charge corona wire and charge grid from being contaminated with toner and paper dust.

Drive:

•

Cleaner affixed to screw rod [A].

•

Unit driven by DC motor [B] located at copier front.

Cleaning:

[D]

•

Grid cleaner pad [C] and charge wire cleaner pads [D].

•

Home position at copier front.

•

Machine cleans according to conditions below:

1) When the main switch is turned on.

2) When the fusing temperature is less than 55oC.

3) When forced using an SP mode (SP2-802).

Cleaning Path:

Copier front – Rear end point – Copier front Only the charge corona grid is cleaned during the traverse from the copier front to

the rear end point (black arrow). Both the charge wire and grid are cleaned during this traversal from the rear end point to the copier front (white arrow).

Position Detection:

•

No sensor to detect the position of the cleaner.

•

I/O control board detects the current supplied to the motor

• It senses the sudden change in the current value, which occurs when the cleaner reaches the end point.

• At the turnaround point, the motor reverses.

• If current does not increase within 60 seconds after motor rotation, the I/O control

board detects an open circuit or disconnected condition, stops the motor, and then displays SC303.

2.4 IMAGE PROCESSING

2.4.1 OVERVIEW

The following features were added to B017/018 copiers or modified from the A258/259/260 copiers.

Image rotation feature

• Rotates up to A3/DLT full color images.

• Maintains the maximum copy speed by feeding paper sideways.

Laser power correction

• A correction value is applied to the laser power.

• This evenly applies the power across the drum surface, preventing uneven

image density images.

600 dpi resolution

• Improved sharpness and gradation of images.

• New dither patterns in copy mode

• Increased productivity in print mode (Prints images out without slowing down

the process speed for 600 dpi.)

NOTE: On the A258/259/260 copiers, the process speed changes to 2/3 of the

standard speed for 600 dpi.

Dither processing

• Two dither patterns for Text and Photo modes

• Dither pattern size is increased to improve gradation.

Pulse positioning control

• Machine can change the start timing for laser exposure.

• Makes lines appear smoother. (This improves the quality of grainy images.)

• The image rotation circuit is located on the LD control board.

• CMYK data processed in the IPU section is sent to the LD control board.

• Image rotation circuit has 80MB memory.

• 64MB to store up to A3/DLT mono toner color image data

• 16MB to store image separation data.

• After the image is rotated in this circuit, dither processing is applied to the image

data and laser exposure begins.

• Since mono-toner color (CMYK) image data can be stored in memory, the scanner only scans the image once to make multi-copies.

IMAGE PROCESSING 28 August, 2000

2.4.4 LASER POWER CORRECTION

B017D507.PCX

Even if the power from the LD unit is the same from side to side, laser power is not evenly applied across the drum surface due to the characteristics of the F-theta and Barrel Torroidal lenses as shown by the curve in the illustration. These characteristics cause the laser power at the center to be slightly stronger than at either side. This causes uneven image density on your printout.

Since all scanner units have the same characteristics, a correction curve is applied to the laser power exposed from the LD unit so that the laser power applied across the drum surface becomes even. The curved line in the illustration becomes straight by applying the correction to the laser power.

2.4.5 DITHER PROCESSING

B017D508.WMF

• Two dither patterns for Text and Photo modes.

• In Text mode, dither patterns are made with 2x2 dot units for fine resolution.

• In the Photo mode, dither patterns are made with 3x3 dot units.

• Using the larger unit makes the image appear smoother, improving the quality of

grainy images.

28 August, 2000 IMAGE PROCESSING

2.4.6 PULSE POSITIONING CONTROL

• The location of the active part of the laser signal can be on either the left or right side of each pixel.

• The positioning of the active part of the laser signal shifts to the left or right depending on adjacent pixel values.

• W hen scanning the gray solid image, top righ t, all active parts locate on the left side of each pixel if pulse-positioning control is not used.

• Engine capability problems cause these thin lines to be reproduced improperly.

• The line is not completely straight because image data was lost. This also causes grainy images.

Detailed

• Pulse positioning control thickens the lines and reproduces them properly without any image loss.

• This causes the lines to appear smoother. (This improves the quality of grainy images.)

DEVELOPMENT UNIT 28 August, 2000

2.5 DEVELOPMENT UNIT

2.5.1 OVERVIEW

To optimize image development, a high frequency AC component has been applied to the development bias. The high frequency AC component improves the quality of grainy images.

[C]

[E]

[D]

B017D518.WMF

B017D519.WMF

When the revolver unit rotates, small amounts of ton er tend to flow into the development unit. This causes the toner concentration to increase. To prevent toner from flowing into the development units, a small window [A] is added to the development shutter [B] and a magnet [C] is attached on to the toner supply pipe [D].

A small amount of developer flows back into the toner supply pipe through the small window on the shutter during the revolver rotation and is caught by the magnet. The developer caught by the magnet functions as a shield and prevents toner from flowing into the development unit. When toner is supplied to the development unit, the supply auger [E] rotates and supplies the proper amount of toner.

28 August, 2000 IMAGE TRANSFER BELT UNIT

2.6 IMAGE TRANSFER BELT UNIT

2.6.1 OVERVIEW

The image transfer function is the same as the A258/259/260 copiers. The changes described below were applied to the B017/018 to improve reliability and image quality.

Image transfer unit positioning

• Changed to maintain the width of the photoconductor gap.

• Changed compression spring position and the shape of the drum stay.

Current feedback system

• Optimized the image transfer bias.

• Automatically corrects the current applied to the belt to apply a constant

optimum transfer bias to the belt.

• This also prevents dark spots.

Touch and release mechanism

• Added a solenoid to the image transfer belt unit.

• Keeps the image transfer belt away from the drum between copy jobs

• Prevents drum fatigue due to residual voltage on the belt.

Paper transfer mechanism

• Added brush to the image transfer belt unit

• Changed the shape of the paper guide of the paper transfer unit.

• Ensures correct paper transfer

• Improves the quality of the toner blaster image.

B017D593.WMF

• The release lever [A] is at the front of the unit.

• Moving the release lever rotates the release lever cam [B].

• Rotating the release lever counterclockwise applies tension to the belt

• The positioning cam [C] located at the end of the release shaft [D] moves in the

same direction.

• The positioning cam moves along the rear frame [E]

• It is pushed outward by the rear frame because of the shape of the cam.

• A compression spring [F] is also located between the end of shaft and the

positioning cam.

• This spring applies the pressure to the image transfer belt unit and places the unit in the proper position.

• To properly place this unit on A258/259/260 copiers:

• Compression spring put on the front side of the image transfer belt unit

• The drum stay presses the spring, which maintains the position of both the

transfer belt and drum units.

• W hen securing the transfer belt stay with screws, its position might fluctuate slightly

• This is due to the pressure applied from the spring, causing the photoconductor gap to change slightly.

• To maintain this gap, the compression spring position and the transfer belt stay shape were changed for the B017/018 copiers.

• A receptacle [B2] was added to the rear side of the belt tension roller.

• This receptacle is connected to the high voltage supply board - T1, PCC [C].

• Current flows from the high voltage supply board to receptacle [B1] to the

transfer bias roller [D] then to the belt. From the belt it is transferred to the tension roller [E] then to the receptacle [B2] and finally back to the high voltage supply board.

• The current fed back to the high voltage supply board changes because the electrical resistance of the belt varies.

• The current applied to the belt is automatically corrected thereby applying a constant optimum transfer bias to the belt.

• If the image transfer belt is always in contact with the drum surface, residual voltage remains on the belt because the bias is always applied to the image transfer belt during operati on .

• Residual voltage may cause drum fatigue, resulting in darker bands on copies.

• A solenoid [A] was added to the image transfer belt unit to prevent drum fatigue.

• The solenoid turns off between each copy job to keep the belt away from the

drum.

• The image transfer belt is in contact with the drum whenever it rotates because the drum motor drives the belt.

• The soleno id turns off to keep the belt away from the drum 100 milliseconds after the drum motor stops between each copy job

• It turns on again 100 millisec onds before the drum motor starts rotating to bring the belt in contact with the drum.

• When the solenoid turns off, the release bracket [B] is pulled by the spring [C].

• The bracket [B] pushes the stay [D] for the insulation roller [E] down, resulting in

approximately a 1-mm clearance between the drum and belt.

2.6.5 PAPER TRANSFER MECHANISM

[A]

B017D596.WMF

• Brush [A], in the image transfer belt unit, pushes the belt down.

• This ensures that paper comes in contact with the image transfer belt before

the electrical field affects the toner on the belt.

• High voltage applied to the paper transfer roller generates the electrical field.

• If this field affects the toner before the paper comes in contact with the belt,

toner will be scattered around the image on the paper or smeared.

While making copies, paper dust is transferred to the paper transport section. The paper transport roller is cleaned by the cleaning blade; however, paper dust may cause cleaning efficiency to drop, resulting in the dirty backgrounds on the back side of copies. To prevent this, a cleaning scraper [A] was added to the registration roller section. The cleaning scraper removes paper dust off of the registration roller. The edge of the scraper needs to be cleaned at every PM to maintain cleaning efficiency.

• A belt fusing system was adopted to reduce the warming-up time.

• Warming-up time is 4.5 minutes.

• The heat roller [A] is made of aluminum

• The fusing belt [B] is made of resin coated with silicone rubber.

• The heat roller and fusing belt heat up faster because the heat conduction

efficiency increased compared to the hot and pressure roller system.

• The heat, hot, and pressure rollers have a fusing lamp:

• 500W [C] for the heat roller,

• 150W [D] for the hot roller [E],

• 400W [F] for the pressure roller [G].

• The heat roller thermistor [H] controls the heat and hot roller fusing lamps.

• These two lamps turn on and off simultaneously.

• The fusing lamp for the hot roller evenly heats the roller. This prevents

uneven fusing for the 1st copy after the power is switched on.

• The pressure roller thermistor [I] controls the pressure roller fusing lamp.

• W hen the main switch is turned on, the fusing rollers start rotating (idling mode) after the fusing belt temperature reaches 150°C.

• The pressure roller then absorbs the heat of the fusing belt.

• Then, the fusing belt temperature drops from 150°C.

• Fusing rollers stop rotating after the fusing belt temperature reaches 150°C,

again.

• Temperature control is normally accomplished by turning the fusing lamps on and off (SP mode (SP1-104).

• Thermostat [J] and thermofuse [K] prevent the temperature in the fusing section from rising to dangerous levels.

• The heat roller thermostat [J] blows at 200°C

• The pressure roller thermofuse [K] blows at 117°C.

2-18

28 August, 2000 FUSING

By adopting a heat roller made of aluminum, the temperature of the fusing belt increases quickly. This may cause the fusing belt temperature to rise too high before the thermofuse blows, therefore the thermostat was adopted. The thermostat is in contact with the non-image area of the fusing belt and blows at 200°C.

• The bus switchboard interfaces the copier with the controller.

• The CIVIC interface between the controller unit and the bus switchboard

transfers image data on an 8-bits/pixel basis for each color.

• The APIP interface between the fax unit and the bus switch board transfers image data on 2-bits/pixel basis for B&W.

• The FCI (Fine Character and Image) chip performs image smoothing and line correction only in the fax mode.

• When the user selects smoothing, the FCI converts the image data (8 bits) to 7 bits of image and 1 bit of pixel positioning data.

• This simulates 1200 dpi resolution across the page.

To use this SP mode, do the following: Print the trim pattern using pattern 1 in SP5-955-

018. Then check that the margins on the trim pattern are as follows:

Lead edge: 5mm (target) +/- 2mm Trailing edge: 2mm (target) +2mm/-1.5mm Side (target): 1.5mm Side (specification): 2+/- 2mm

Adjust the magnification in the sub-scan direction first using SP2-113-02. Then print the trim pattern again. Adjust the magnification in the main scan direction with SP2-112-02.

Adjust SP2-113-02 (sub-scan) first and print the trim pattern again before adjusting SP2-112-02 (main scan), because SP2-113-02 also affects the main scan magnification.

NOTE: Do not adjust SP2-113-002 by more than +/- 0.5% at any one time.
