High- voltage Charge roller power supply 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.
  • Page 324 DESCRIPTION OF PRINT OPERATIONS (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.
  • Page 325 DESCRIPTION OF PRINT OPERATIONS (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.
  • Page 326 DESCRIPTION OF PRINT OPERATIONS (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.

  • Page 484: Outline

    Outline This specifications describes the addition and modification caused to mount functions using FAX2NET service (that is a facsimile service via internet) in the OKIOFFICE84/OKIFAX 4500. FAX2NET Services Service Types The FAX2NET service is a facsimile communication service using the FAX2NET-supplied internet.

  • Page 485: Setup Items

    The FAX(B) only performs the normal G3 facsimile receiving operation; so, the user need not prepare a special protocol. (4) Web retrieval Request route: FAX(A) -> FAX2NET server (P) Receiving route: Web server (W) -> FAX2NET server (P) -> FAX(A) Web server (W) and server (P) are connected via internet.

  • Page 486: Destination Registration

    Destination Registration 3.2.1 E-mail Address Registration An E-mail address can be registered in up to 10 portions fitting to on-touch keys 1 to 10. Each address must be composed of up to 64 characters: uppercase letters, lowercase letters, digits, and symbols. For details on the applicable characters, see Section 5.4. The user can begin E-mail address registration by selecting E-mail registration in the one- touch destination registration.

  • Page 487: Menus

    Menus For details on the menus, see Operations. 3.3.1 User Program Add item “FAX2NET Server Registration” to No. 8. Under “FAX2NET server registration,” specify a FAX2NET server telephone number, FAX2NET account number, and international telephone prefix. 3.3.2 Location Program When “registration in one-touch key” is selected, if an account number is already registered, branches appear so that the user can select whether a telephone number E-mail address or Web URL is to be registered.

  • Page 488: Characters Allocated To One-Touch Keys

    The following characters can be used on each character entry screen by allocating them to one-touch keys 1 to 6. The CAPS function is allocated to one-touch key 7; so, it is valid at entry of an E-mail address and Web URL. See Fig.3 OKIOFFICE84/OKIFAX 4500 control panel.

  • Page 490: Functions

    The result of communication with the FAX2NET server is described in the Activity report. Whether a target call arrives at the last destination cannot be recognized from OKIOFFICE84/ OKIFAX 4500. The user must confirm the communication result on the FAX2NET Web page.

  • Page 491: E-Mail Address

    The communication with the FAX2NET server for each destination is the same as of a single- destination sending. The OKIOFFICE84/OKIFAX 4500 assumes that the sending to the destination is completed after the sending to the FAX2NET server ends. At printing of a broadcasting end report, therefore, data may not arrive at the remote facsimile.

  • Page 492: Web Printing

    Web Printing 4.3.1 Requests Web printing begins by selecting a one-touch key in which Web URL is registered as a destination. If information about a Web address or FAX2NET server is not registered, Web retrieval is invalid. To prepare for Web printing, first convert a character string registered as a Web address according to the conversion table shown in Section 5.4.

  • Page 493: Confidential And Relay Sending

    Non FAX2NET Dialing In case the user does not desire the facsimile transmission via the FAX2NET server, the user can cancel dialing to the FAX2NET server by specifying "+" prior to dialing of the international telephone prefix. Confidential and Relay Sending The FAX2NET function is not used for confidential and relay sending.
  • Page 494 Telephone number registration application on PC The application or driver group for MFP function is not changed from OKIOFFICE84/ OKIFAX 4500; therefore, the following item is limited: The telephone number registration application on PC cannot register an E-mail address in a one-touch key or change the contents for each one-touch key. The column of a one-touch key in which an E-mail address is registered is not registered from the tele- phone number application on PC.
