the printer uses a metric-style fuse (5 x 20 mm iec) rated at f5a, 250v. the end caps of the fuse must bear the certification mark of a known international safety organization (see figure 37 on page 97).
depending on the model you have, the fuse may not be user-replaceable (see figure 30) and may need to be replaced by a qualified service technician. please see the maintenance manual (part # 32056l) for details.

models with a user-replaceable fuse have a warning label next to the fuse for easy identification.
