After a lot of printing, the blue tape that is on the glass plate may wear or damage a little bit. This can cause an uneven print surface or bad adhesion to the print and it is therefore recommended to replace it once in a while.
1. Removing the acrylic build plate
Push on the acrylic build plate and slide it sidewards so you can take it out.
2. Replacing the blue tape
Push on the acrylic build plate and slide it sidewards so you can take it out. Now you can remove the damaged tape and place new strokes of blue tape on the acrylic build plate. Place the acrylic build plate back in the Ultimaker Original and carefully push and slide it to put it in position and secure it.
Tip: In order to be sure about a successful next print we recommend to re-level the build plate after having repositioned the acrylic plate.
