  • Page 42: Compatibility

    OVERVIEW This module contains three sections. • Transmitter Theory of Operation • Receiver Theory of Operation • LED Printer Theory of Operation 1.1.01 Compatibility The facsimile machine operates as a Group 3 (G3) facsimile device. 1.1.02 Communications Mode The unit operates as a half-duplex facsimile transceiver. Transmit and receive operations cannot take place at the same time.

  • Page 43: Automatic Fall-Back Mode

    1.1.04 Automatic Fall-back Mode The unit will change the message transmitting speed according to the following fall-back plan. The first page of the message is transmitted at 14.4 kbps (Okifax 2200 communicates at 9600 bps maximum). The receiving station will continuously monitor the received data. If the receiving station detects six or more consecutive error lines during reception of a single page, or if the total number of errors detected during the reception of a single page exceeds 10% of the data on the transmitted page, it will return a Retrain Negative (RTN) signal to the transmitting...

  • Page 44: Error Correction Mode (Ecm)

    1.1.06 Error Correction Mode (ECM) Error Correction Mode (ECM) provides error-free transmission when communicating with a remote unit that also has ECM. Here is an explanation of the ECM process. • The transmit machine groups image data into blocks and transmits one block of data at a time to the receive machine.

  • Page 45: Quick Scan Mode

    1.1.07 Quick Scan Mode Both the Okifax 2400 and Okifax 2600 have quick scan capability. With MEM Transmission enabled, the units will scan documents placed on the ADF tray into memory.

Photosensors • Outlet Sensor (PS1) ON: Paper is present Detects paper jams at the paper exit path.

  • Page 69: Fuser Unit

    1.4.05 Fuser Unit The fuser unit is controlled by a thermistor, the printer interface gate array (PIGA), an LSI, and the CPU to keep the heat roller surface temperature within a predetermined range (about 150 degrees Celsius). A thermal fuse within the fuser unit prevents abnormal temperature rises in case the thermistor fails.

  • Page 70: Printing Process

    PRINTING PROCESS Idle Gear 1.5.01 General Information Registration Motor Hopping and feeding are controlled by a single Registration Roller registration motor. Hopping Turning the registration motor in the "A" direction Roller drives the hopping roller. Turning the registration motor in the "B" direction drives the registration roller.

  • Page 71: Hopping

    1.5.02 Hopping Hopping loads paper from the paper cassette. During the hopping operation, the registration Paper motor turns in a clockwise direction. This motor drives the hopping roller, which in turn advances the paper until the inlet sensor 1 switches ON. The registration gear turns, but the one-way bearing does not allow the registration roller to turn.

  • Page 72: Exposing

    1.5.05 Exposing The image drum has four layers. • Carrier Transfer Layer (CTL) Carrier Generation Layer (CGL) • Underlayer (UL) • Aluminum Base • The CTL and CGL make up the organic photo conductor layer (OPC), which is about 20 micrometers (µm) thick.

  • Page 73: Developing

    1.5.06 Developing The electrostatic latent image formed on the image drum surface is developed into a visible image. Developing takes place when contact is made between the image drum and the developing roller. As the toner supply roller rotates, toner is absorbed into the sponge type roller material.

  • Page 74: Transfer

    1.5.07 Transfer The transfer roller is made of a conductive sponge material. The roller keeps the paper in constant contact with the image drum. Paper is placed over the image drum surface. A positive charge (opposite Image in polarity to the toner) is applied to the paper from Drum the reverse side.

  • Page 75: Printing

    1.5.10 Printing Refer to the Printing Process Diagram. Printing is accomplished as follows. • Approximately - 1.3 Kvdc is supplied to the charge roller. This causes the drum to charge to approximately - 750 vdc. The LED head is turned ON by the printer control board in accordance with signals •...

    1.6.02 Toner Low Sensor The toner well of the image drum cartridge contains a toner agitator. Whenever the image drum rotates, the toner agitator attempts to turn. A spring clip in the bottom of the toner well (along with the proper amount of toner) holds the agitator at the bottom of the well. However, when toner is distributed unevenly or an insufficient amount of toner is in the well, the toner agitator will rotate.

    TELEPHONE ANSWERING DEVICE (TAD) INTERFACE (Pertains to the Okifax 2200 only) C.3.01 General Information The Telephone Answering Device (TAD) Interface allows Okifax units to share the same phone line with a telephone answering device. The Okifax unit and answering device work together to process incoming voice and fax calls, each to their own function.
  • Page 377 The Okifax unit waits for the answering device to disconnect the line. Once the Okifax unit senses that the answering device has dropped the line, it begins automatic reception.

When the answering device disconnects the line, the Okifax unit will seize the line and attempt automatic reception.
