Section 7: Replacement Procedures
FUSE REPLACEMENT
The M84Pro Printer has three fuses; one is externally accessible and is wired to the power
supply while the other two are located internally and directly connected to the main circuit board.
There is an additional fuse integrated into the optional cutter assembly which is easily accessible
by opening the cutter attachment.
This procedure will address only the power supply and circuit board fuses.

5 Locate fuses (3) located on main circuit board (4).
6 Manipulate fuses (3) for their contact clips (5) and determine their condition. Replace as
required.
