The blower fan is part of an assembly (fan, metal sheet, printed part). Let's remove it as one piece and disassemble it in parts later on.
⬢Release the first screw on the support.
⬢Hold the blower fan assembly with one hand.
⬢Use the other hand to release the second screw on the support.
⬢Remove the blower fan assembly and place it next to the printer, like in the picture. Do not pull the cable!
⬢If the assembly does not reach a sufficient distance, try moving the zip tie to the right. If it's too tight, cut the zip tie (pliers from the SL1 kit, needle-nose pliers, nail scissors). Be careful not to cut the cables!
