Refer to Figure 4-52. A user-replaceable AC power fuse is located just to the left of the
power switch. For 120 VAC operation, a F5A/250V fuse is used. For 220 VAC operation,
a F3A/250V is used.
1. Turn the printer Off (O), and remove the AC power cord.
2. Insert the tip of a flat-blade screwdriver into the slot found on the fuse holder cap.
Press in on the cap and turn counterclockwise. Remove the screwdriver.
3. Grasp the fuse holder cap with your fingers and remove from the fuse holder.
4. Remove the blown fuse from the fuse holder cap and insert the proper fuse.
5. Replace the fuse holder cap by placing it into the fuse holder. Insert the tip of a flat-
blade screwdriver into the slot found on the fuse holder cap. Press in on the cap and
turn clockwise until the cap will no longer turn. Remove the screwdriver.
Caution:
The replacement fuse must have the ratings specified below. Serious damage may
occur if a higher-rated fuse is installed.
Note • Do not rely on a visual inspection to determine whether a fuse is blown. Always
turn the printer off and remove the power cord. Then remove the fuse from the fuse
holder (or circuit board) and test with an ohmmeter. A good fuse gives a short (0 ohm)
indication.
