Ensure the glass print base is clean and install it in the printer, being sure to line up the flat corners of the print base with the flat parts of the corner brackets in the tilt tray.
WEAR 100% nitrile gloves whenever handling PRINTER COMPONENTS. This is to both prevent material from getting on your hands and prevent transfer of dirt and oil from your hands to the plate. fingerprints and debris on the plate can interfere with the light projected by the print engine and result in failed builds.
When inserting the print tray into the tilt tray, ensure that the FRONT label is facing forward.
Install the print tray inside the tilt tray, locking all four toggle-case latches.
