(3) Function 1) Scanned image receiver (optical receiver) An acquired image by the scanner is converted into an optical signal and then transmit- ted through the optical cable. The transmitted image is received by the optical receiver of the MFB board. The image data is transmitted with a high-speed transmission clock of 36.75 MHz. 2) Storage coder/decoder (FCUE LSI) The coder function codes image data into stored code data. The decoder function decodes stored code data into image data. 3) Image memory manager (FCUE LSI) This block reads/writes the stored code data through interface units (the scanner, the printer, and the communication units) from/into DRAM FILE by the unit of 1 block. The maximum data throughput for DRAM FILE is 320 Mbps. A time division method is used to refresh read/write of the data through the interface units, and DRAM FILE. 4) Image memory (DRAM FILE) Standard system has 16MB; 8MB on the MFB board and a ROT boards (8MB). The maximum capacity is 64MB by installing another ROT board and a TMEM board.
Each memory board (ROT (8MB,16MB) and TMEM (32MB)) has its designated slot. Be careful when you insert it. 5) Printer controller (FCUE LSI) It processes the line density conversion for print image data (serial data) from the stor- age decoder, and stores it in the internal frame memory. The converted data is read syn- chronized with the PPC printer, added information on the left margin and the white mask, and then output to the printer as serial data. The frame memory can hold up to 20 Kbit of data to be output to the printer. The printer controller exchanges commands/statuses for controlling the printer unit. 6) Modem (V.34 modem) This modem has a digital signal processor (DSP), an analog front end (AFE) for A/D and D/A conversions, a modem F/WROM, and boot memory (SRAM). It follows the electrical communication standards of the recommended V.8, V.34, V.17, V.29, V.27ter, V.21ch2, T.3, and T.4. It also follows the T.30 binary signal procedure. The transmission speeds are 33600, 31200, 28800, 26400, 24000, 21600, 19200, 16800, 14400, 12000, 9600, 7200, 4800, 2400, and 300 bps. This modem has PB tone sending for PB calling. It is located on the memory map of the MFB board. 7) Communication controller (FCUE LSI and IPUS LSI) This controller performs necessary functions (relay control, ringer detection, line connec- tion detection, polarity reverse detection, dialing and pulse sending) for G3 communica- tion. It also detects the frequency of the tonal signal of G3 communication. 8) Image memory backup circuit This backup circuit switches the power source supply unit to the battery while the system is turned OFF or during power source failure so that the stored data in the image file memory (maximum 64MB) is being held.

[3] Function of each block(1) CCD driver This driver is built in the ESP2 LSI and generates a clock for CCD driving.(2) CCD output image processor 1) Analog processor Two image signals from the CCD board are sampled and held by the analog processor. Then it restores the black level, adjusts the gain, mixes the 2 signals (i.e., adjusts the levels of the 2 CCD image signals to convert into 1 image signal), and then outputs the mixed signal to the A/D converter. 2)A/D converter The A/D converter receives the analog signal from Analog processor, converts it into a digitized parallel signal (8 bit for each pixel), and then outputs the digitized signal to the ESP2 LSI.(3) Binary image processor This processor is also built in the ESP2 LSI. It normalizes an 8 bit image signal from the A/D converter (shading correction), and processes it for high image quality (gamma cor- rection and image region separation). It also performs MTF correction (ABC and moving average), and binary process (floating slice, dithering, and error diffusion). The binary image processor also performs zooming and the white mask process. The processed image signal is converted into serial data to output to the optical transmission I/F.(4) Optical transmission I/F This block converts an electrical (serial) signal from the ESP2 LSI into an optical signal in order for transmitting to the MFB board. The optical image signal and a synchronized clock signal will be transmitted.(5) Motor controller This controller is built in the ESP2 LSI. It generates signals for control, magnetic field excitation patterns, and currents of the motors of the Book scanner and the ADF scanner.(6) Sensor I/F circuit This controller is also built in the ESP2 LSI. It receives information such as the document size, the position of the top of the document, and the status of the cover, from sensors of the Book scanner and the ADF scanner. The sensor I/F circuit has a filtering circuit for removing chattering of signals from sensors.(7) ADFR I/F This circuit is built in the ESP2 LSI. ADF I/F sends command to the ADFR unit and it receives the status information from the ADFR unit.

<<11>> NCUK Board[1] OverviewThe NCUK board has various functions such as line connection, ringer detection, off-hook detection, polarity detection, and dialing pulse transmission.
[2] Block diagram
[3] Function of each blockLINE is a modular port for connecting a phone line. TEL is another modular port to connect an extra telephone set.CML is a relay that switches from phone to fax. It will be turned ON by pressing the commu-nication switch, detecting a ringer, or a facsimile calling signal. TR1 of the dial pulse trans-mitter is then turned ON to establish a DC-connection with the transformer (T1) The NCUK board cannot be used in the back to back mode because a signal from LINE is DC-connected through ST1 of the dial pulse transmitter. The actual connection with the line is necessary for testing this board. The dialing pulse transmitter outputs dial pulses controlled by the MFB board. The ringer detector provides an automatic reception function. It isolates a receiver ringer signal with a photo-coupler, and outputs it to the MFB board. The ringer signal is counted by the counter of G/A.The polarity detector uses two photo-couplers to detect the DC polarity of the line. If either of the detected signals is "1", the other signal is "0."The off-hook detector shares a circuit with the polarity detector, and detects off-hook, i.e., direct current.

<<1>> Image Processing Flow• Image processing is made up of the following blocks.
1. Photoelectric Conversion (CCD Sensor)• Light reflected off the original is received through mirrors and lens by the CCD Sensor
which, in turn, outputs the corresponding data to the HGB Board.2. HGB Board• After converting the data received from the CCD to an analog signal, the board converts
it to 8-bit image data (A/D conversion). It further makes various corrections and outputs the resultant image data to the MFB Board over an optical cable.
3. MFB Board• This board compresses the image data received from the HGB Board, stores it, and
uncompresses it.• The image memory has a standard capacity of 16MB and can be expanded up to 64MB
(optional).4. PH• Emits a laser beam according to the image data provided by the MFB Board to expose
the surface of the PC Drum.

<<2>> Scanner and 2nd/3rd Mirrors Carriage Moving Mechanism<Scanner>• During a scan, the Scanner projects an even amount of light from the Exposure Lamp
onto the entire surface of the original. The light is reflected from the original to the 1st Mirror of the scanner and then to the 2nd and 3rd Mirrors.
• The Scanner is driven by the Scanner Motor and front and rear Scanner Drive Cables.• Scanner speed is determined by the set zoom ratio in reference to the full size mode.• The Scanner is at home position when Scanner Home Position Sensor 1 is blocked. This
position serves as the reference for the scan motion.• Scanner Home Position Sensor 2 determines the home position of the Scanner when
AF-7 is used.
<2nd/3rd Mirrors Carriage>• The 2nd and 3rd Mirrors are mounted to their holder at right angles to each other. They
direct the light reflected off the 1st Mirror through the lens to the CCD.• The 2nd/3rd Mirrors Carriage is also moved by the Scanner Drive Cables and pulleys
driven by the Scanner Motor. It travels at a speed half that of the Scanner, thereby keep-ing constant the optical path length between the Original Glass and lens.

1. PC Drum• The drum is an aluminum cylinder coated with photosensitive material on which an elec-
trostatic latent image is produced.
2. Drum Charging• A scorotron charger employing a comb electrode generates a negative DC charged
layer on the surface of the PC Drum.
3. Photoelectric Conversion Section• The Exposure Lamp directs light onto the original. The light reflected off the original is
directed and resized by the mirrors and lens so as to produce a reduced-size image on the CCD Sensor.
4. HGB Board• Converts an electric signal into a corresponding 8-bit digital image signal (A/D conver-
sion), makes various corrections, and outputs the results to the MFB Board.
5. MFB Board• Compresses the image data received from the HGB Board, stores it, and uncom-
presses it.
6. Laser Exposure• The laser beam emitted from the LD (laser diode) strikes the surface of the PC Drum,
creating an electrostatic latent image.
7. Development• Negatively charged toner adheres to the latent image on the PC Drum surface, creating
a visible image.
8. Paper Feed• Feeds sheets of paper from the appropriate paper source.
9. Image Transfer• An Image Transfer Roller is used. A positive charge applied to the roller causes the vis-
ible image on the surface of the PC Drum to transfer onto the front side of the paper.

The drum consists of an aluminum base coated with a charge generation layer and a charge transport layer.
Handling PrecautionsProlonged exposure to light can cause the photoconductor surface of the drum to suffer light fatigue, resulting in a loss of photosensitivity. If the I/C is removed from the copier, it should be wrapped in a soft, clean, opaque cloth or other protective covering to prevent exposure to light.
• Grounding of the PC DrumThe PC Drum ground point is located inside and at the front end of the I/C as viewed from the front of the copier and in constant contact with the Drum Holding Shaft. When the I/C is installed in the copier, the Drum Holding Shaft contacts the ground point. This provides for assured grounding of the PC Drum through the ground plate in the rear to the frame of the copier.

<<1>> Sleeve/Magnet Roller• This copier employs the MT-HG system with a Sleeve/Magnet Roller having the following
magnetic characteristics.• Turning of the sleeve surrounding the Magnet Roller ensures that fresh developer from
the Developer Mixing Chamber is always being conveyed to the point of development with respect to the PC Drum.
N1 : The point of development with the maximum magnetic flux density which ensures that the carrier is firmly held onto the Sleeve Roller when toner is attracted to the latent image.
S1, N2 : The magnetic flux density between these two poles is made low to ensure that the developer remaining on the surface of the Sleeve Roller is smoothly recy-cled. They also prevent developer from scattering.
N3 : The developer brush is formed by this pole and its height is moderated before the brush is regulated by the Doctor Blade.
S2a : This pole ensures that the developer is conveyed to the point of development over the wide interval between N3 and N1.
S2b : If developer is compacted and clogs at the Doctor Blade and, as a result, part of the surface of the Sleeve/Magnet Roller is not covered with developer, the nearby developer around this pole with a weak magnetic force goes to those uncovered areas. This helps prevent white lines from occurring on the copy.

<<2>> Developing Bias• The amount of toner attracted onto the surface of the PC Drum is controlled by varying
the developing bias voltage.• As the PC Drum deteriorates and its photoconductive layer begins to wear, it becomes
more sensitive to the increase in the amount of toner. As a countermeasure against this problem, the developing bias voltage is automatically switched according to the PC Drum temperature, thereby stabilizing the image quality level.

<<3>>ATDC Sensor• The ATDC Sensor automatic adjustment is made when a new I/C is installed in the
copier. Toner replenishing control is thereafter controlled as detailed in the following.
[1] ATDC Sensor Automatic Adjustment• The ATDC Sensor is automatically adjusted when a new I/C is loaded in the copier. Dur-
ing this sequence, the copier reads the sensor output value and sets it as the reference. This reference value is stored in memory and used until the I/C reaches its service life.
[2] Toner Replenishing Control• While the I/C Motor is turning, the ATDC Sensor samples T/C and, according to the read-
ings, the copier provides the following controls.
✽ Toner replenishment represents the operation of the Sub Hopper Toner Replenishing Motor.
[3] Toner Empty Control (T/C Recovery Mode)• When the control is passed onto the T/C recovery mode, the Sub Hopper Toner Replen-
ishing Motor is energized to replenish the supply of toner into the Developing Unit and, if T/C is recovered to a level of 14% or higher (2.32V or less) within 150 sec., it resets the toner-empty condition.

<Temperature Control by Mode>• The mode that is initiated following the completion of a warm-up cycle varies as detailed
below depending on the machine condition and the Fusing Roller temperature at the restart of temperature control.
<<4>> CPM Control• As a measure to prevent the temperature on the edges of the Fusing Rollers (over which
no part of paper passes) from rising in a multi-copy cycle using small size paper (width of 250 mm or less), the paper feed interval is made greater.
<Control>• If a sheet of small size paper is taken up and fed in during mode 1, control is switched to
mode 2.• The number of sheets of small size paper that are fed through is counted.
<Timing>• The counter reaches 30.• The plain/special paper counter reaches N specified below:
If the control is in mode 1 or mode 2 when the counter starts counting, N = 30.If the control is in mode 3 when the counter starts counting, N = 100.
<Resetting>• If a period of 2 min. or more elapses, during which the counter does not count up after
the counter has started counting, the counter is cleared resetting the CPM control.

The minimum margins are 4 mm*.* The minimum margins can be adjusted with Edge erase adjustment.
<<2>> Printing Mode There are 2 printing modes available to this system. The soft switch (MODE 007) toggles these modes. They are valid only for printing received documents.[1] Automatic reduction modeIf the length of a received document exceeds the printable area, this mode cuts off the doc-ument within the cutting length specified with the soft switch (MODE 007). If the excess length is longer than the specified cutting off length, the document will be reduced within the upper limit of reducing the size specified with the soft switch (MODE 007).
[2] Cut off modeIf the length of a received document exceeds the printable area, this mode cuts off the doc-ument within the cutting length specified with the soft switch (MODE 007). (No reduction.)

<<3>> Paper Selection Mode (facsimile)This system has the following modes for selecting paper. The soft switch (MODE 008) tog-gles these modes. They are valid only for printing received documents.
[1] Standard modeThis mode selects paper to avoid document splitting as much as possible.Example Available sizes of paper : Letter Lengthwise and 11” X 17” Lengthwise Size of received document : 11” X 17” Lengthwise Printing mode : Automatic reduction (Upper reduction limit of 60%) In this case, the system will use the 11” X 17” paper without reduction. If the 11” X 17” paper has run out, the Letter Lengthwise paper will be used with reduction.
[2] Width preference modeThis mode selects paper whose width is the same as or smaller than a received document.(Example) Available sizes of print paper : Letter Lengthwise and 11” X 17” Lengthwise Size of received document : Letter Lengthwise Printing mode : Automatic reduction (Upper reduction limit of 60%) In this case, the system will use the Letter paper with reduction. If the Letter paper has run out, the printing job will be halted and wait for new paper.
[3] Fixed width mode This mode selects paper whose width is the same as a received document.(Example) Available sizes of paper : Letter Lengthwise and 11” X 17” Lengthwise Size of received document : 11” X 17” Lengthwise Printing mode : Automatic reduction (Upper reduction limit of 60%) In this case, the system will use the Letter paper with reduction. If the Letter paper has run out, the printing job will be halted and wait for new paper.
Note:The standard and the preference modes have 4 different submodes. Each of them has pri-orities for selection. (Users can select only submode1.)
Submode 1 :Selecting a paper whose width is the same as a received document with-out reduction.
Submode 2 :Selecting a paper whose width is the same as a received document with minimum margins (minimum non printing area).
Submode 3 :Selecting a paper to print out without reduction. (The width will not be considered.)
Sub mode 4 : Selecting a paper with minimum nonprinting area. (The width will not be considered.)

• When laser protective goggles are to be used, select ones with a lens conforming to the above specifications.
• When a disassembly job needs to be performed in the laser beam path, such as when working around the printerhead and PC Drum, be sure first to turn the copier OFF.
• If the job requires that the copier be left ON, take off your watch and ring and wear laser protective goggles.
• A highly reflective tool can be dangerous if it is brought into the laser beam path. Use utmost care when handling tools on the user’s premises.
• The printerhead is not maintainable in the field. It is to be replaced as an assembly including the control board. Never, therefore, attempt to remove the laser diode or adjust trimmers on the control board.

6-1-3. INSTRUCTIONS FOR HANDLING THE PWBS WITH MOS ICSThe following precautions must be observed when handling P.W. Boards with MOS (Metal Oxide Semiconductor) ICs.
During Transportation/Storage:• During transportation or when in storage, new P.W. Boards must not be indiscriminately
removed from their protective conductive bags. • Do not store or place P.W. Boards in a location exposed to direct sunlight. • When it becomes absolutely necessary to remove a Board from its conductive bag or
case, always place it on its conductive mat in an area as free as possible from static elec-tricity.
• Do not touch the pins of the ICs with your bare hands.
During Replacement: • Before unplugging connectors from the P.W. Boards, make sure that the power cord has
been unplugged from the outlet.• When removing a Board from its conductive bag or conductive case, do not touch the
pins of the ICs or the printed pattern. Place it in position by holding only the edges of the Board.
• Before plugging connectors into the Board, make sure that the power cord has been unplugged from the power outlet.
During Inspection:• Avoid checking the IC directly with a multimeter; use connectors on the Board. • Never create a closed circuit across IC pins with a metal tool.• When it is absolutely necessary to touch the ICs and other electrical components on the
PW Board, be sure to ground your body.
6-1-4. HANDLING OF THE IMAGING CARTRIDGEDuring Transportation/Storage: • Use the specified carton whenever moving or storing the Imaging Cartridge.• The storage temperature is in the range between –20°C and +40°C.• In summer, avoid leaving the Imaging Cartridge in a car for a long time.
Handling: • Ensure that the correct Imaging Cartridge is used. • Store the Imaging Cartridge in a site that is not exposed to direct sunlight.
Precautionary Information on the PC Drum Inside the Imaging Cartridge:• The PC Drum exhibits greatest light fatigue after being exposed to strong light over an
extended period of time. Never, therefore, expose it to direct sunlight. • Use care not to contaminate the surface of the PC Drum with oil-base solvent, finger-
prints, and other foreign matter.• Do not scratch the surface of the PC Drum. • Do not apply chemicals to the surface of the PC Drum. • Do not attempt to wipe clean the surface of the PC Drum.

This section shows diagnoses of system troubles by alarm codes and their remedies. The default setting for diagnostic codes is “not to be displayed.” If you experience errors fre-quently, setup the soft switch (MODE 020) to display diagnostic codes. Then follow tables 9-1-1 and 9-1-2 for troubleshooting.• Table 9-1-1 shows communication error codes. Each of them has 6-digits on the panel
and a report.Codes 00 to B4 indicate the upper 2 digits. Adding internal 4 digits to them to display 6 digits on the panel and a report.Communication reports (TX and RX) print out diagnostic codes for up to 50 activities. Any codes older than those activities cannot be printed.
• Table 9-1-2 indicates printer alarm codes, which have 2 digits on the panel screen.Before you proceed with a remedy according to the tables, make sure that the power source cable and the connectors are connected properly.
