Page 441 A2.2 Explanation of Signal Flowchart (1) Copy Mode The analog data output from the image sensor is input to the MCNT-PCB to be amplified by the amplifier. The amplified analog data is input to the scanner controller. Next, the analog data is converted to digital data by the built-in A/D converter. The digital data is corrected by the internal correction function, transferring binary-coded data to the IOGA5 every eighth pixel.
Page 442 (6) PC Print The data input from the MCNT’s parallel I/F is input, through the IOGA5, to the DRAM using DMA. The input data is transferred to the DEC block in the IOGA5 using DMA. In the DEC block, the data is expanded in the 1-line raster buffer in the IOGA5. Then, the expanded data is sent to the video block in the IOGA5 in response to a 1-line syn- chronous signal.

Page 464 A3.1.11 Centronics Parallel Interface The LSI sets a BUSY-P signal to ON at the same time when it reads the parallel data (PDATA1-P to PDATA8-P) from the parallel port at the fall of STB-N signal. Furthermore, it makes the store processing of receiving data into a receive buffer terminate within a certain fixed time and outputs an ACK-N signal, setting the BUSY-P signal to OFF.
Page 465 A3.1.12 Electrophotographic Process The electrophotographic processing is outlined below. The electrophotographic printing process is shown in Figure 2-4. 1 Charging The surface of the image drum is charged uniformly with a negative charge by applying the negative voltage to the charge roller. 2 Exposure Light emitted from the LED head irradiates the negatively charged surface of the image drum.

Page 469 (a) Hopping 1 For hopping, the registration motor turns in direction "a" (clockwise direction) and drives the hopping roller to advance the paper until the inlet sensor turns on (in this case, the registration gear also turns, but the registration roller is prevented from turning by the one-way bearing.) 2 After inlet sensor is turned on by the paper advence, the paper is further advanced to a predetermined distance until the paper hits the registration roller (the skew of the...
Page 470 (2) Charging Charging is actuated by appliciation of the DC voltage to the charge roller thta is in contact with the image drum surface. Charge roller Power supply Image drum The charge roller is composed of two layers, a conductive layer and a surface protective layer, both having elasticity to secure good contact with the image drum.
Page 471 (3) Exposure Light emitted by the LED head irradiates the image drum surface with a negative charge. The surface potential of the irradiated portion of the image drum drops, forming an electrostatic latent image associated with the image signal. LED head LED head Charge roller Power...
Page 472 The image drum surface is charged to about -750 V by the contact charge of the charge roller. When the light from the LED head irradiates the 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 image drum.
Page 473 (4) Developing Toner is attracted to the electrostatic latent image on the image drum surface, converting it into a visible toner image. Developing takes place through the contact between the 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 (the developing roller surface is charged positive and the toner, negative.)
Page 474 Note: The bias voltage required during the developing process is supplied to the toner supply roller and the developing roller, as shown below. -500 VDC is supplied to the toner supply roller, -265 VDC to the developing roller. Connected and bias supplied when the cover is closed.
Page 475 (5) Transfer The transfer roller is composed of conductive sponge material, and is designed to get the image drum surface and the paper in a close contact. Paper is placed over the image drum surface, and the positive charge, opposite in polarity to that of the toner, is applied to the paper from the reverse side.
Page 476 (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.
Page 477 (7) Cleaning When the transfer is completed, the residual toner left on the image drum is attracted to the cleaning roller temporarily by static electricity, and the image drum surface is cleaned. Image drum Cleaning roller Power supply Transfer roller (8) Cleaning of rollers The charge, transfer and cleaning rollers are cleaned for the following cases: •...

Page 499 A3.6 High-voltage Power Supply Circuit This high-voltage power supply circuit receives the high-voltage generation timing control command that is transmitted in serial through the power supply interface from the control section. It decodes this command by LSI (IC2) and outputs high-frequency pulses to the corresponding high-voltage generating circuits through pins 11, 12, 13, 14 and 15 of LSI (IC2).

Page 505: Appendix Bdescriptions Of Print Operation
The M76 board supervises the heat roller temperature via the thermistor, and regulates the heater roller at a predetermined temperature (about 185 ˚C for OKIFAX 5750/5950) by connecting or disconnecting the AC voltage supply to the heater.
Page 506 B.2 Description of Print Operations B.2.1 Process Operations 1) Hopping and feeding Hopping and feeding are affected by a single resist motor in the mechanism shown below. Resist motor Idle gear Resist roller Hopping roller Resist gear Motor gear Hopping gear Turning the resist motor in the "a"...
Page 507 (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.
Page 508 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.
Page 509 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 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.
Page 510 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...
Page 511 The EP (image) drum surface is charged to about -800 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.
Page 512 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.
Page 513 Note: The toner supply roller and the developing roller are supplied with bias voltages required during the developing process as shown below. -500 VDC is supplied to the toner supply roller, -265 VDC to the developing roller. Connected and bias voltage supplied when the cover is closed.
Page 514 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.
Page 515 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.
Page 516 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. EP drum Cleaning roller Power supply unit Transfer roller 8) Cleaning of rollers The charge roller, transfer roller and cleaning roller are cleaned in the following cases: •...

Page 518 B.3.2 Major Trouble Errors B.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.

This Maintenance Manual is intended for the maintenance personnel and describes the field mainte- nance methods for Second Paper Feeder option of OKIFAX 5750/5950 Series Facsimile Transceiver. Refer to the Instruction sheet of High Capacity Second Paper Feeder option for equipment handling and operation methods.
Page 734 OUTLINE Functions When the Second Paper Feeder is installed with the OKIFAX 5750/5950 series facsimile transceiver, the Second Paper Feeder is connected to the facsimile by a connector. The Second Paper Feeder supplies paper automatically through the operation of pulse motor (hopping), which is driven by signals sent from CPU of the Second Paper Feeder under the control of the facsimile.
Page 735: Mechanism Description
MECHANISM DESCRIPTION General Mechanism The Second Paper Feeder feeds the paper into the facsimile by receiving the signal from the facsimile, which drives the pulse motor inside the Second Paper Feeder, and this motion is transmitted to rotate the one-way clutch of the hopping frame assembly. The paper is delivered from the hopper into the facsimile through the turning of the hopping roller and feed roller.

Page 894 Network Printing Printing Documents To print documents to your fax machine via the LAN you need to install the appropriate soft- ware from the supplied CD-ROM and make the correct settings for your environment. Note: When printing on transparencies, set the Media Type to Light, use the manual feed method, and set the machine output for face up stacking.
Page 895 Windows 3.1 Recommended process: 1) Install printer driver. 2) Run SETUP.EXE from the Win31 directory on the supplied CD-ROM. 3) Configure network card. When printing from Windows 3.1 a NetWare Server is required as Windows 3.1 is not a network operating system. “Printing via LPR,” from Windows 3.1 connected to the network with other commercial TCP/IP protocols, is not assured.
Page 896 Setting Items You can alter network settings by selecting UF93: NETWORK SETTINGS. To print from Windows using Lpr, it is necessary to set the IP ADDRESS. This is not required if printing from NetWare only, but it is necessary for using InternetFAX functions. 1: IP ADDRESS Sets the IP address.

Page 902 6.2.2 Mail Server In many cases, the DNS server configuration explained in Section 1 is all you need to use the email-to-FAX relay service. However, some mail servers are configured to process all mail addressed to hosts belonging to their domain as mail to themselves. If mail server mail.abc.com has been set up in this way, it will regard mail to xxxx@fax.abc.com as mail to one of its users and will not forward it to the OKIFAX5950.

Page 904 This document describes the system specification of real time Internet Fax functions with FX056e/176e. The real time Internet FAX functions with FX056e/176e will be available when an optional board made by Oki Electric is installed. These functions comply with ITU-T.38. Hereafter, real time Internet FAX is described as IPFAX.
Page 905 One touch addition IP address A number with “*” at the beginning is considered to be an IP address. Each octet is divided by “*” instead of a period. Example) *192*168*001*254 If upper digits are identical with the device IP address, the upper digits can be omitted. Example) device IP address: 202.250.128.020 →Assumed as *202*250*128*254.
Page 906 Basic performance of transmitting IPFAX call designation 4.1.1 One touch In case a telephone number added to One Touch is IP address or IPFAX telephone number, a call is made via an IPFAX board. The characters and the number of digits that IPFAX can use as telephone numbers are limited, however, there is no such limitation with a main unit.
