3. Load the Label Roll

If you haven't already, load the label roll on the label spindle.

  • Center the roll using the fins
  • Unlock the label guides and open to widest setting
  • Insert paper under metal bar, guides, and teal sensor arm
  • Hint: Before inserting, fold a few labels face-in so the curve is easier to direct under the metal bar
  • Close the label guides until label doesn't slide left or right
  • Lock the label guides
  • Ensure labels travel smoothly

4. Load NEW Ribbon

Hold the NEW ribbon spool so the hex ⬣ side is on the left, pointy side to right.

Load the ribbon roll onto the NEW ribbon spool so the ribbon unrolls from the bottom.

Insert the hex ⬣ side first (left), then slide the pointy side into place (right).

9. Turn On and Calibrate

The first time you turn on a mydpi printer it will perform a calibration. This will advance ribbon. At any time you can run an automatic calibration by holding the feed button (front-bottom-right) until the printer beeps, then let go.

Each press of the feed button should eject one label.
