This chapter will guide you through calibrating and preparing the printer for its first run.
Make sure there is nothing on the heatbed. The heatbed must be clean. Any dirt can damage the surface of both the heatbed and the print sheet.
Attach the sheet by first aligning the rear cutout with the locking pins on the back of the heated bed. Hold the sheet by the front two corners and slowly lay it down onto the heated bed - watch your fingers!
Keep the print sheet clean for optimum performance.
#1 cause of prints detaching from the print surface is a greasy print sheet. Use IPA (Isopropyl alcohol) to degrease it if you have touched its surface before.
Put the O-ring onto the spoolholder.
Push the spoolholder into the Puck-universal and lock it in by turning clockwise.

Worth noting for new users of Prusa.
When looking at the holes in the front of the plate (nearest you), it looks like there is a protective plastic film, that you might think needs to be peeled.
I was i doubt, and had search a bit, until I found the description of the plate in the store where it says "Both sides of this sheet are covered by a sticker made from smoothed PEI plastic"...
Ahh, no I should definitely not peel that :-)
