A2.1 Explanation of Signal Flow for OKIOFFICE44/OKIFAX 4100/5000 Series Note : Regarding the difference of the signal flow between OKIFAX 4100 and OKIFAX 5000 series, since one-line scanning processing speed of OKIFAX 5000 series is faster in comparison with OKIOFFICE 44/OKIFAX 4100, to the circuit diagram of OKIFAX 5000 series has been added the EXSEED (image processing LSI) and SRAM (dark/light level correction data). Otherwise, the signal flow is almost the same as in OKIOFFICE 44/OKIFAX 4100.
(3) G3 receive Mode Figure A2.1.3 (For OKIOFFICE 44/OKIFAX 4100)/Figure A2.2.3 (For OKIFAX 5000 series) show the G3 receive picture signal route In the G3 mode, the high-speed picture signal arriving from the telephone line at L1 and L2 of NCU passes through the transformer T1 and the amplifier and is input to the MODEM as “R” signal. After demodulation by modem, the picture data is sent to CPU. The CPU performs the picture data processing (decode) for this picture data and stores into the DRAM.
(7) Memory Transmission This signal route describes the memory transmission used in broadcast mode, delayed broadcast mode, etc. The stored encoded data undergoes buffering, passes through CPU, MODEM and NCU and then sent out to the telephone line. (8) Memory Reception This signal route describes the memory reception used in no-paper mode, no-toner reception, confidential mode, etc.

Figure B1-1 shows the layout drawing of the electro-photographic processor. (1) Image drum unit The image drum unit makes a toner adhere to the formed electrostatic latent image with static electricity. This electrostatic latent image is formed by the lights irradiated from LED heads.

(3) Pulse motor (Main) This pulse motor of 48 steps/rotation is two-phase excited by the signal from the main control board; it performs feeding control by switching normal rotation to reverse rotation or vice versa and turning on/off the electromagnetic clutch. The relationship between the main motor, electromagnetic clutch, regist gear, drum gear, hopping roller is shown in the table below and on the subsequent pages.

B1.2 Electro-Photographic Process (1) Electro-photographic process The electro-photographic process is outlined below. 1 Charging The surface of the OPC drum is charged negatively and uniformly by applying the DC voltage to the CH roller. 2 Exposure Light emitted from the LED head irradiates the negatively charged surface of the OPC drum. The surface potential of the irradiated surface attenuates to form the electrostatic latent image corresponding to the image signal.
40055101TH Rev.
B1.2.1 Explanation of Each Process Operation (1) Hopping As shown in the figure below, the clutch for hopping is turned on/off according to current ON/OFF to a coil. When the clutch is OFF Spring for resetting Hopping gear Clutch plate Coil Magnetic substance plate Pin Hopping shaft Hopping roller Engagement section When the clutch is ON Hopping gear Clutch plate When the clutch is on, the hopping gear engages with the clutch plate to rotate the hopping roller.
(2) Printing and warm-up At warm-up Triple gear Transfer gear Resist gear Idle gear Planetary gear a" a' a Hopping gear Gear A Pulse motor (main) Rotate the pulse motor (main) in the a direction. The planetary gear rotates in the a’ direction, dislocating its position in the a” direction. This causes the planetary gear to be separated from gear A. The hopping gear will not rotate. The triple gear and transfer gear rotate via the idle gear to drive the EP unit.
(3) Charging Charging is performed by applying DC voltage to the charge roller that is in contact with the surface of the OPC drum. Highvoltage power supply Charge roller OPC drum (4) Exposure Light emitted from the LED head irradiates the negatively charged surface of the OPC drum. The surface potential of the irradiated surface attenuates to form the electrostatic latent image corresponding to the image signal.
(5) Development The electrostatic latent image on the surface of the OPC drum is changed to a visible toner image by applying a toner to it. Development is performed in the contact part between the OPC drum and developing roller. 1 The sponge roller negatively charges a toner and applies it to the developing roller. Developing blade Charge roller Sponge roller Developing roller OPC drum 2 The toner applied to the developing roller is thin-coated by the developing blade.
(6) Transfer The transfer roller is composed of conductive sponge material. This roller is set so that the surface of the OPC drum and sheets of paper will adhere closely. A sheet of paper is placed on the surface of the OPC drum and the positive charge opposite to the negative charge of a toner is applied from the reverse side by the transfer roller.
(7) Fusing The transferred unfused toner image is fused to a sheet of paper because heat and pressure are applied when it passes between the heat roller and back-up roller. The Teflon-coated heat roller contains a 400 W heater (Halogen lamp) that heats the heat roller. The thermistor on the surface of the heat roller keeps the temperature of the heat roller constant. A thermostat is also installed for safety. If temperature rises abnormally, this thermostat opens to suspend voltage supply to the heater.
B1.3 Paper Jam Detection The OKIOFFICE 44/OKIFAX 4100 monitors the paper status when the power supply is on and during printing. In the following cases, the OKIFAX 4100 interrupts the printing process as a paper jam. Printing can be recovered by opening the cover, removing the jammed paper, and closing the cover. Error Paper inlet jam Cause of Error • Only the manual feed sensor detects "Paper exists" when the power supply is on.

APPENDIX B2 DESCRIPTIONS OF PRINT OPERATION (OKIFAX 5000 SERIES) B2.1 Mechanical Components 1) EP drum cartridge The EP (image) cartridge consists of an EP (image) drum, a charger, and a developer. The cartridge forms a toner image on the drum, using an electrostatic latent image formed by the LED print head. 2) Resist motor This resist motor is a pulse motor of 48 steps/rotation that is two-phase excited by the signal from the M17 board.
Figure B2.1 Layout of Print Station Components 40055101TH Rev.
B2.2 Description of Print Operations B2.2.1 Process Operations 1) Hopping and feeding Hopping and feeding are affected by a single resist motor in the mechanism shown below. Idle gear Resist motor Resist roller a Hopping roller b Resist gear Hopping gear Motor gear Turning the resist motor in the "a" direction drives the hopping roller. Turning the resist motor in the "b" direction drives the resist roller.
(a) Hopping 1 Hopping turns the resist motor in the "a" direction (in the CW direction) and drives the hopping roller to advance the paper until the inlet sensor turns on. (In this case, the resist gear also turns, but the resist roller is prevented from turning by the one-way clutch gear.) 2 After the paper has turned on the inlet sensor, the paper is further advanced by a predetermined length until the paper hits the resist roller. (The skew in the paper can thus be corrected.
(b) Feeding 1 After end of hopping, turning the resist motor in the "b" direction (in the CCW direction) drives the resist roller to advance the paper. (In this case, the hopping gear also turns, but the hopping roller is prevented from turning by the one-way clutch gear.) 2 The paper is further advanced in synchrony with the print data. EP drum Paper b Hopping roller Transfer roller Resist roller CCW = Counterclockwise 40055101TH Rev.
2) Charging Charging is affected by applying a DC voltage to the charge roller thta is in contact with the EP (image) drum surface. Charge roller PWU EP drum The charge roller is composed of two layers consisting of a conductive layer and a surface protective layer that has elasticity, in order to secure a good contact with the EP (image) drum. When the DC voltage (-1.35 KVDC) applied from the Power Supply Unit exceeds a threshold value, charging begins.
3) Exposure Light emitted from the LED head irradiates the EP (image) drum surface with negative charges. The surface potential of the irradiated part of the EP drum drops, thereby forming an electrostatic latent image associated with the image signal. Charge roller LED head LED head PWU EP drum Paper EP drum The EP (image) drum is coated with an underlayer (UL), a carrier generation layer (CGL), and carrier transfer layer (CTL) on the aluminum base.
The EP (image) drum surface is charged to about -750 V by the contact charge of the charge roller. When light from the LED head irradiates the EP (image) drum surface, the light energy generates positive and negative carriers in the CGL. The positive carriers are moved to the CTL by an electrical field acting on the EP (image) drum. Likewise, the negative carriers flow into the aluminum layer (ground).
4) Developing Toner is attracted to the electrostatic latent image on the EP (image) drum surface to convert it into a visible toner image. Developing takes place at the contact between the EP (image) drum and the developing roller. 1 As the toner supply roller rotates while rubbing on the developing roller, a friction charge is generated between the developing roller and the toner, allowing the toner to be attracted to the developing roller.
Note: The toner supply roller and the developing roller are supplied with bias voltages required during the developing process as shown below. -450 VDC is supplied to the toner supply roller, -300 VDC to the developing roller. Connected and bias voltage supplied when the cover is closed. Toner supply roller Developing roller Base EP drum 40055101TH Rev.
5) Transfer The transfer roller is composed of conductive sponge material and is designed to make the EP (image) drum surface and the paper closely into contact. Paper is placed over the EP (image) drum surface, and a positive charge, opposite in polarity to the toner, is applied to the paper from its reverse side.
6) Fusing After the end of the transfer operation, the unfused toner image is fused on the paper under heat and pressure as it passes between the heater roller and the back-up roller. The heater roller with a Teflon coating incorporates a 500 W heater (Halogen lamp), which heats the heat roller. A thermister, which is in contact with the heater roller, regulates the heater roller at a predetermined temperature (about 185 ˚C for OKIFAX 5000 series).
7) Cleaning After the end of the transfer, residual toner on the EP (image) drum is attracted to the cleaning roller temporarily by static electricity to clean the EP (image) drum surface.

B2.3.2 Major Trouble Errors B2.3.2.1 Fuser Error The fuser error indicates an error in thermister on heater. In case the fuser error occurs at the time of printing, the heater is turned off soon but the printing continues of that page. However, if the error occurs before the write sensor is turned on, the motor stops soon. B2.3.2.2 Fan Error The fan error is generated when the FANSNS signal lead goes "1" while the fan is running at full speed.
B2.3.2.3 Paper Feed Monitoring Status Description and Supervising Sensor Distance Indicates monitoring error in hopping. Hopping is retried 3 times. 118 mm or less path Length +36 (hopping) x 3 Transport system jam 1 Indicates an error in the paper transport path. Error on resist roller section.

No paper in 2'nd cassette Response from the option tray indicated no paper in 2'nd tray.
B2.3.3.1 Toner Low Detection • Composition The device consists of the stirring gear which rotates at a constant rate, the stirring bar and the magnet on the stirring bar. The stirring bar rotates through the link on the protrusion in the stirring gear. The configuration of stirring bar in the figure below may differ. The principle of toner detection, however, remains the same.
Low Toner Alarm A check for low toner is carried out at all times when the drum is rotating (rotation in opposite direction is excluded). • The toner sensor is not monitored while the drum motor is in halt. TONER FULL state TNRSNS-N t1 TONER LOW state TNRSNS-N t1 T • When the toner low state is detected 2 times consecutively, Toner Low is established. • When the toner full state is detected 2 times consecutively, Toner Low is cancelled.
B2.4 Other Special Cases B2.4.1 Manual Paper Feed Turning on of the inlet sensors without the hopping operation indicates manual paper feeding for OKIFAX 2350/2450 (excluding when power is on). B2.4.2 Cleaning The image drum needs cleaning since it gets dirty after having printed copies for a number of times.
