Gate Height Adjustment (Aluminium Model)

Adjusting gate height for Refill Hopper error, (aluminium model)

Adjusting Feed Gate Height

Height Check

1. Test to see if the gate opening is high enough by inserting a card lengthwise into the slot.  It should fit under the gate without resistance and can reach the rubber rollers on the inside.  For best results when testing, the bottom card should be a foil.
   
   
2. If the gate is high enough to accommodate one card, see if it is possible to pass a second card through at the same time.  Try to insert the card lengthwise to check that both sides are square.  Only one card should fit.  Press down on the second card very firmly and try to push it under the gate.  If the gate height is correct, you should not be able to.  This second card will likely be damaged, so don't use anything expensive!
   
3. Check that the gate opening is square with the base plate.

If a single card cannot pass through or has friction with the gate, the gate must be adjusted up.  If two cards can pass through or may become wedged the gate must be adjusted down.

Tools Needed

• 2.5mm or 7/64" Allen key (provided) - For the adjustment screws
• 2mm or 3/32" Allen key (provided) - For the cover plate

Adjustment Procedure

1. Remove the extended feed hopper using the thumb screws on each side.
2. Remove the four 2mm screws and remove the top cover plate to expose the gate beams and adjustment screws.
   
3. Loosen the 2 locking screws by turning them counter-clockwise.  They do not need to be removed.
   
4. Loosen all 3 top screws (counterclockwise).  The side screws should go to the top of the gate edge, the middle screw should be raised slightly.  This is the starting position.
5. Press the gate down with your hand from above.
6. Screw the middle screw down (clockwise) until you feel it make contact with the bottom beam.  At this point, the gate should be very low, and you should not be able to put a card or shim under it.  If it is not this low, press down on the gate by hand until it lowers.
   
   
7. Begin tightening the side screws (clockwise) in small 1/8 to 1/16th turns, alternating sides.  This will raise the gate.  After adjusting each side, try to fit a card under the gate.  It should be able to fit under without any resistance.  As you tighten the sides, it may be necessary to loosen (counterclockwise) the middle screw slightly if the side screws become too tight.
8. Repeat the Height Check above.  One card should be able to go under the gate easily.  Two cards, even with force applied should not fit under the gate.  You may also use the gate shims.  They should have some resistance from the gate edge, but the resistance should be the same at all points.
   1. If one card cannot fit, the gate is too low.  Continue turning the side screws clockwise in small amounts (1/16th of a turn) until the single card fits without resistance from the metal gate.  It may be necessary to loosen the middle screw (counterclockwise) if the side screws cannot be further tightened.
   2. If two cards can fit, the gate is too high.  Adjust the side screws counterclockwise in small amounts (1/16th of a turn) and tighten the middle screw (clockwise) until two cards cannot fit even with force applied.  Note that even if a lot of force is needed, if an edge of the 2nd card can fit under the gate at any point, the gate is too high.  Make sure the gate is level.
9. When satisfied with the gate height, tighten the locking screws, then loosen the center screw.  Run a test sort of ~250 cards with the weight.  In some circumstances, the weight can function better when used backward (the arrow points out of the machine).
   1. If no cards enter the scanner, the gate may be either too low (no cards get through) or too high (2 cards pinch or jam).   Loosen the locking screws and go back to Step 8.
   2. If multiple cards enter the scanner, the gate is too high.  Loosen the locking screws, go back to Step 3, and slightly lower the gate.
