4.3 REPLACEMENT PROCEDURES (Cont'd)
4.3.3 Replacing Fuse
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 filament 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 4-3) from fuse cylinder (2) located on rear housing cover (3).
3. Withdraw damaged fuse (4) from fuse cap (1).
4. Insert the replacement fuse (4) into fuse cylinder (2) and screw on cap (1).
Caution
Replace fuse of equal rating, T3.15A 250V. Do not use a fuse with a higher rating.
Note
• The fuses may be inspected by looking for a void in its filament or by using a multimeter to check for
circuit continuity.
• Fuse amperage and voltage rating may be found stamped into the fuse's metal contacts or labeled
on the printer's rear.
• 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.
Caution
IMPROPER FUSE USAGE MAY RESULT IN DESTROYED ELECTRICAL COMPONENTS AND/OR
FIRE. MAKE SURE 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.
