Installing the teflon mat and wear strip

Printer 1 and printer 2 must be powered off before you start this task.

  1. Shut down and power off the system.
  2. Remove all forms from printer 2.
  3. Open the center and top covers of the printer.
  4. Open the back cover, the stacker gate and stacker door, and the oiler gate to allow the air flow to help cool down the preheat platen.
    CAUTION:
    <60> High temperature. Let parts cool at least 30 minutes in this area before handling.
  5. Attach the teflon mat and wear strip to the clip as follows:
    CAUTION:
    <2-24> Sharp edges exist in this area.
    1. Lay the wear strip (4) and teflon mat (6) on a flat surface with the sensor cutouts (5) as shown. Lay the clip (3) on top of the mat and wear strip so that the lip (1) faces up.
    2. Insert the clip through the slots in the mat and wear strip as shown. To make the installation easier, use cellophane tape (2) to attach the mat and wear strip to the clip.
      ""
    3. With the clip inserted into the mat and the wear strip, and the mat and strip taped in place on the clip, roll the mat and wear strip (2) up and over the top of the clip (1) so that the sensor cutout (3) will face the front of the printer when you install the assembly on the shutter vacuum plate.
      ""
  6. Install the entire assembly onto the preheat platen through the preheat platen entry area:
    1. Bring the bottom edge of the mat up to the clip and loosely hold the mat in your left hand and the clip in your right hand.
      ""
    2. Position the assembly so that the clip is lined up with the shutter vacuum plate (1), from the front to the back of the printer.
      ""
    3. While holding the clip in your right hand, release the mat from your left hand, and let it unroll onto the preheat platen (2). Ensure that the mat and wear strip lay flat on the preheat platen and that the holes are aligned, front to back, with the holes in the shutter vacuum plate.
    4. Press the clip firmly down onto the top right edge of the vacuum plate along the complete length of the vacuum plate (front to back of the printer). The ends of the clip will fit over the shaft that is below the vacuum plate.
    5. Using your right hand, gently slide the mat from side to side until you can feel that the holes on the lower part of the mat are securely engaged with the pins protruding from the preheat platen (3). Ensure that the cutout on the mat is positioned correctly around the skew sensor (4) and that the mat is aligned correctly with the red line at the entry point of the preheat platen (to the right of the skew sensor).
  7. Power on the system.
  8. Reload the forms. See "Working with Forms" for loading instructions.
  9. Close the center and top covers, the back door, the stacker gate and stacker door, and the oiler gate.
  10. Adjust the temperature and check the fusing quality as follows:
    1. For forms over 42 pounds, increase the preheat temperature setting to 100 (Printer Definition -> Print Quality). For heavy weight paper less than 42 pounds, set the preheat temperature to 70.
      Note:
      Wait at least three minutes after increasing the temperature before running test prints.
    2. Run some test prints to ensure proper fusing.
    3. If the fusing needs adjustment, increase the temperature of the preheat platen.
    4. If good fusing cannot be obtained, remove the wear strip, run test prints again, and check the fuse grade again.
  11. Select Start on the printer operator panel or on the Main touchscreen panel for the affected printer.

    CAUTION:
    <85>For printers with microcode levels, version 11.6.128 and higher, both printers and attached pre and postprocessing equipment can be started from the main panel of the printer console and the printer operator panels. Visually assure that no other personnel are working on the system before starting the system.
