    This means that the tank must be drained for oil and water on a regular basis. If the air is supplied from the smaller types of compressors delivered from Braillo Norway AS, it’s required to keep the compressor in a similar environment as described for the printer itself. (Temper- ature 15 - 30°C (60 - 86°F) and rel.
  • Page 29 BRAILLO B650 SF2.1 Filtering and drainage To stop oil and water from getting into the printer, there are filters and drainage units in the line. Some of this filters need to be drained, and some is automatically drained. How often the manual draining has to be done depends on many things e.g. the temperature and humidity in the environment around the compressor and the workload on the compressor.

  • Page 101: Magnet Rack - Adjustment

    BRAILLO B650 SF2.1 6.10 Magnet rack - adjustment Before placing the magnet rack in the printer, two adjustments must be checked. The first is the distance between the support list and the pivot arms. This is the travelling distance for the pivot arm.
  • Page 102 BRAILLO B650 SF2.1 Sponge list The second adjustment is the pressure the sponge list makes against the pivot arms. The sponge list works as a return spring for the pivot arms. The correct adjustment is when the sponge list is slightly pressing against the pivot arms, but the pivot arms can still move freely.

    BRAILLO B650 SF2.1 Scrap paper hatch Is a hatch that will open so the scrap paper that is cut off at the beginning of a print job can fall down into the waste bin. The speed the hatch moves up and down can be adjusted with one-way flow control valves fitted on the cylinder.

  • Page 144: Picker

    BRAILLO B650 SF2.1 Picker Consists of a servo motor that will move the vacuum arm back and forth, and a pneumatic cylinder that moves the arm up and down. Used to pick up the printed sheets and move them into the folding and stapling position, and to move the covers to the pile.

  • Page 145: Vacuum Arm

    BRAILLO B650 SF2.1 Vacuum arm The vacuum arm has 7 suction cups and is used to lift and move the sheets. The vacuum needed is made in an ejector that is placed just beside the vacuum arm. The vacuum sensor will discover if a sheet falls off the vacuum arm during the movement.

  • Page 146: Sheet Splitters

    BRAILLO B650 SF2.1 Sheet splitters When the vacuum arm is lifting a cover from the pile, the sheet splitters is blowing air into the pile to help separate the sheets. The amount of air in the two nozzles at the sides is controlled by the regula- tor just behind the cover magazine.

  • Page 147: Stack Holders

    BRAILLO B650 SF2.1 Stack holders The stack holders are two cylinders that will move down and keep the stack of sheets aligned until the stapling is done. The downward force can be adjusted with the regulator on the valve ramp.

  • Page 148: Stapling

    BRAILLO B650 SF2.1 Stapling The stapling is engaged by the stapling cylinder that goes down and up again. This movement will drive the two Hohner 43-6 staplers to staple at the same time. The stapling is done with 0.5 mm steel wire that the staplers will form, cut, and press through the pile of paper and then crimp it on the un- derside in one movement.
