FUSE REPLACEMENT

The fuse is wired to the power receptacle and protects the printer from power surges from the electrical source. If a surge of electricity reaches the fuse, its filiment will melt creating a disruption of the flow. In order to bridge the gap so the printer may again be functional, the damaged fuse must be replaced.

1.Switch off the printer and disconnect power supply cord.

2.Unscrew fuse cap (1, Figure 6-3) from fuse cylinder (2) located on rear housing cover (3).

3.Withdraw damaged fuse (4) from fuse cap (1) and insert replacement fuse (4) in its place.

4.Insert replacment fuse (4) into fuse cylinder (2) and screw on cap (1).

NOTE: The orientation of the fuse does not matter. It only has to be installed into its respective cylinder and be able make contact on each end to function.

NOTE: Fuse amperage and voltage rating may be found stamped into the fuse’s metal contacts or labeled on the printer’s rear.

CAUTION: IMPROPER FUSE USAGE MAY RESULT IN DESTROYED

ELECTRICAL COMPONENTS AND/OR FIRE. ENSURE THE DAMAGED FUSE IS

REPLACED WITH ONE OF IDENTICAL PHYSICAL DIMENSIONS AND

AMPERAGE. TO DO THIS, DUPLICATE THE INFORMATION STAMPED ON THE

FUSE’S METAL CASING.
