Adjusting Anvil and Table Height

The print-wheel stamps against a hard surface - the anvil. Some Premere machines have an adjustable anvil, and some do not.

Pin-Type Adjustable Anvils

The Premere has a limited range of stamp depth adjustment, so when adjusting the machine to stamp on different kinds of product, it's often necessary to adjust the height of the anvil. This creates more or less space between the print-wheel and the anvil, allowing you to fit products of different thickness into the machine. In addition to the anvil adjustment, the Premere's table itself moves up and down. The anvil and table adjustments are independent of each other, but they must be set together. To adjust the anvil position for a particular product, follow these steps. . .

1. Measure the thickness of your product, and enter this value into the Product Thickness field In iStamp. If you're using a fixture, make sure you enter the appropriate value for Fixture Thickness.
2. Set the Stamp Depth to zero.
3. Look at the Anvil Height box. Notice that there are are eight round colored dots. These represent the possible anvil positions for the thickness and depth settings you just entered. They're color-coded as follows:
- Green is an acceptable anvil position. The machine can stamp properly when the anvil is set to this position.
- Gray is OUTSIDE of the range of acceptable anvil positions. The machine doesn't have enough depth adjustment range to properly stamp when the anvil is set to this position.
- Blue is the current setting IF it's in the range of acceptable anvil positions.
- Red is the current setting IF it's OUTSIDE the range of acceptable positions.
4. Click on one of the green dots to set the anvil to one of the acceptable anvil positions. Lower positions are preferred as this provides more space between the anvil and the print-wheel.

Note that we haven't actually adjusted the anvil position. We've only told iStamp where it is that we WILL set the anvil. Now we have to ACTUALLY adjust the anvil position.

5. The anvil is mounted to the front of the machine's frame beneath the table. The anvil is a tall, narrow block of metal mounted to the frame by two bolts. Sticking out of the side of the anvil is a register pin. This rests on the anvil height pin inserted into one of several holes in the front of the machine. Notice that this pattern of holes matches the pattern of dots in the anvil height box in iStamp. The location of the anvil height pin MUST match the BLUE dot in the anvil height box.

6. With the anvil wrench, loosen the two bolts that secure the anvil to the machine's frame. The anvil will now slide up and down easily.
7. Lift the anvil so that you can pull out the anvil height pin. Move it to the hole that matches the anvil height setting in iStamp. Release the anvil so that the register pin rests on the anvil height pin.
8. Tighten the anvil bolts securely.

Now that we've adjusted the anvil, we have to adjust the table to match it.

9. Four black, plastic lever-screws secure the table to the machine. These are located at the back of the table, two each to either side of the anvil. Loosen these four levers so that the table can move up and down freely. If you can't loosen the levers because they bump into something, you can reposition them - pull the lever out and turn it to a better spot. When all four levers have been loosened, the table will fall to the bottom of its travel.

10. Use the table adjustment arm to lift the table back up. We want to position the table as closely as possible to the height as the anvil.

11. Look at the anvil across the surface of the table, and lift the table so that the anvil just disappears from sight. Lower it back down so that it appears again. Position the table so that it is exactly flush with the surface of the anvil.

12. While holding the table at this height, tighten the four lever-screws. Make sure you don't let the table slip to another position. Hold it steady until you've tightened all four lever-screws.

You're done adjusting the table. Double-check your work: make sure that the anvil pin is set to the same position as indicated in iStamp, and check that the anvil and table surface are both at the same height.
