Zebra Printer Z4M plus

Direct Thermal Mode: After every roll of media (or 500 feet of fanfold media).

Thermal Transfer Mode: After every roll of ribbon or three rolls of media.

These intervals are intended as guidelines only.

You may have to clean more often, depending upon your application and media.

Caution • 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. You are not required to turn off the printer power when working near an open printhead, but Zebra recommends it as a precaution.

If you turn off the power, you will lose all temporary settings, such as label formats, and you must reload them before you resume printing.

To clean the media compartment and sensors, complete these steps:

1. Brush or vacuum any accumulated paper lint and dust away from the media and ribbon paths.

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

Caution: Do not use your left hand to assist in closing the Peel assembly. The top edge of the Peel roller/assembly could pinch your fingers.

Media backing is removed to expose the pinch roller

Pinch roller is cleaned with the swab from the Preventive Maintenance Kit (part number 47362) or a solution of 90% Isopropyl alcohol and 10% deionized water and a cotton swab

Excess adhesive is removed from the tear-off/peel-off bar using the swab

Warning: This procedure requires trained personnel with PPE!

Close the peel assembly to prevent bending the tear-off/peel-off bar during cleaning

Use the Preventive Maintenance Kit (part number 47362) or a solution of 90% Isopropyl alcohol and 10% deionized water and a cotton swab to remove excess adhesive from the tear-off/peel-off bar. Allow the solvent to evaporate

Note: Apply minimum force when cleaning the tear-off/peel-off bar. Excessive force can bend the tear-off/peel-off bar, which can have a negative effect on peel performance

Open the peel assembly by pivoting the module toward you

Manually rotate the pinch roller and clean thoroughly with solvent and a swab. Allow the solvent to evaporate

You can minimize printhead wear and maintain print quality with regular preventive measures.

Over time, the movement of media or ribbon across the printhead wears through the protective ceramic coating, exposing and eventually damaging the print elements (dots). To avoid abrasion:

• Clean the printhead frequently, and use well-lubricated thermal transfer ribbons with backings optimized to reduce friction.

• Minimize printhead pressure and burn temperature settings by optimizing the balance between the two.
