Replace Fuse
The R110Xi fuse must be replaced only by an authorized service technician.
The printer uses a metric-style fuse (5 × 20 mm IEC) rated at F5A, 250 V. The AC power entry
module comes with two approved fuses in the fuse holder: one is in-circuit, and the second is
provided as a spare. The end caps of the fuse must bear the certification mark of a known
international safety organization (see Figure 7 on page 11).
To replace a faulty fuse, complete these steps:
1. Use a small-blade screwdriver or similar tool to remove the fuse holder.
The fuse holder is part of the AC power entry module at the rear of the printer (Figure 48).
Figure 48 • AC Power Entry Module
2. Remove the faulty fuse and install a new fuse in the in-circuit position (Figure 49).
Caution • Turn the AC power switch Off (O) and remove the power cord before performing
this procedure.

Important • If you use the spare fuse, be sure to order a replacement fuse from your
authorized Zebra distributor. The spare fuse should be the exact type and rating as the
original in-circuit fuse.
