A4 size (Min.) 356mm • Ink, glue, and correcting fluid on documents must be dry before the documents can be transmitted. • All clips, staples and pins must be removed from documents before transmission. • Patched (taped) documents should be copied first on a copier and then the copies used for transmission.
FO-IS125N [5] Installation 3. Attaching the tray 1) Attach the paper tray. 1. Site selection Take the following points into consideration when selecting a site for this model. ENVIRONMENT • The machine must be installed on a level surface. • Keep the machine away from air conditioners, heaters, direct sunlight, and dust. • Provide easy access to the front, back, and sides of the machine.
FO-IS125N 4. Connecting the power cord 7. Connecting the machine to your network Plug the power cord into a 120 V, 60 Hz, grounded AC (3-prong) outlet. To use the Scan to E-mail and Scan to Folder functions, and to use the machine as a printer, you must connect the machine to an Ethernet network. In addition, to use Scan to E-mail, the network must have an Internet connection. A typical setup is shown below. • Do not plug the power cord into any other kind of outlet.
FO-IS125N 2) Press the release ( 1 ) and open the front cover ( 2 7) Grasp the cartridge handle and insert the toner cartridge into the print compartment, sliding it along the guides. ). 2 1 3) Open the side cover. Grasp this handle to insert the cartridge. • Make sure the cartridge “clicks” into place. • Do not touch the roller in the toner cartridge. 8) Close the side cover ( cover ( 3 1 ), the front cover ( 2 ), and the top ). 4) Remove the new drum cartridge from its packaging.
FO-IS125N 9. Resetting the drum counter 3) Push the paper plate back. Each time you install a new drum cartridge, follow the steps below to reset the drum counter to zero. 1) Press and then INFO 2) Press until [LIFE] appears in the display. , then until [CLEAR DRUM COUNTER] appears. • 3) Press START . 10. Manually resetting the toner counter When a new toner cartridge is installed, the toner counter is reset in Step 9 on the previous page.
FO-IS125N [6] Clearing paper jams 4) Close the operation panel, pressing down firmly on both sides to make sure it clicks into place. 1. Clearing a jammed document If the original document doesn’t feed properly during transmission or copying, or [DOCUMENT JAMMED] appears in the display, first try pressing START . If the document doesn't feed out, remove it as explained below. 1) Open the operation panel. 2. Clearing jammed printing paper 1) Open the top cover of the machine.
FO-IS125N 4) If the jammed paper is protruding from the front of the machine, gently pull it out. Take care not to tear the paper or leave any torn pieces of paper in the print compartment. • If this clears the jam, go to Step 5. • If you are unable to clear the jam in this way, go to Step 4. • Take care not to touch or allow other objects to contact the drum (the green cylinder). This may damage the drum.

A laser beam is used to expose on the OPC surface to form latent electrostatic images, which are developed into visible images (toner images) and are transferred on paper. The basic operation is composed of the five processes: charging, exposure, development, transfer, and cleaning. 7.2.

FO-IS125N 7.5. Functions and operations of major parts 7.5.2 Developing unit Latent electrostatic images formed by laser beam on the OPC drum are developed to visible images by the developing unit. Toner is filled in the developing unit. Paper Optical unit(LSU) a. Developing roller The developing roller is made of silicon and has a high electric resistance. It is flexible and is in close contact with the OPC drum.
FO-IS125N 7.6. Image forming operation STEP 1 (Cleaning, Charging): STEP 2 (Exposure): Residual toner the OPC drum is stirred and negative charges are scattered evenly on the OPC drum. (The OPC drum surface is evenly charged.) Laser beam scanning light corresponding to the print data is radiated on the OPC drum. Positive and negative charges are generated in the OPC drum CGL exposed with the laser beam.
FO-IS125N STEP 3 (Development): On the other hand, when an area of OPC drum which was not exposed to the laser beam and did not lose its charge comes in contact with the developing roller, any residual toner attached to the OPC drum is transferred to the developing roller which is more positively charged. Toner is attached to the latent electrostatic images on the OPC drum to form visible images. As a result, unnecessary toner on the OPC drum is collected by the developing unit.
FO-IS125N STEP 5 (Paper separation): The paper is separated from the OPC drum. STEP 6 (Discharge): The drum surface is discharged to facilitate cleaning of the drum surface. (The remaining toner is easily collected by the main charger roller.)
