Zebra Printer 170XiIIIPlus

Perform these procedures at the following times:

• Direct Thermal Print Mode: After every roll of labels or 500 ft (150 m) of fanfold labels.

• Thermal Transfer Print Mode: After every roll (1500 ft or 450 m) of ribbon.

Warning: Turn the AC power switch off (O) and remove the power cord before performing this procedure.

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.

Use a small-blade screwdriver or similar tool to remove the fuse holder.

Remove the faulty fuse and install a new fuse in the in-circuit position.

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

Snap the fuse holder back into the AC power entry module.

Reconnect the power cord, and turn the printer on (I).

Warning: The printhead may be hot and can cause severe burns. Allow the printhead to cool.

Before touching the printhead assembly, discharge any built-up static electricity by touching the metal printer frame or by using an anti-static wriststrap and mat.

While performing any tasks near an open printhead, remove all rings, watches, hanging necklaces, identification badges, or other metallic objects that could touch the printhead.

Open the printhead assembly by rotating the printhead-open lever counter-clockwise.

Using the swab from the Preventive Maintenance Kit, wipe along the brown strip on the printhead assembly from end to end.

While manually rotating the platen roller, clean it thoroughly with the swab.

Reload the media and the ribbon.

Push down the printhead assembly, and then rotate the printhead-open lever clockwise until it locks into place.

Warning: Ensure the machine is turned off and unplugged before starting the cleaning process.
