Maintenance; Routine Cleaning; Replace Fuses - Cembre MG3 Operation And Maintenance Manual

For the best printing results, we recommend:
• Using only genuine Cembre materials (media, printer ribbons, spares and cleaning kits).
• Handling blank media sheets carefully to avoid touching the print surface with the fi ngers.
• Before printing, always check the cleanliness of the sheets. If necessary wipe the surface with a soft cloth.
• Keeping new or partially used sheets clean and dry, eg in their original packaging.
• When printing partially used sheets, ensure there are no protruding sprues, burrs along the sheared edges or
tags bent upwards which may damage the print head.
• When printing partially used sheets, ensure the Jump function is used correctly to avoid printing non-existent
media, contaminating the support template and possibly causing irrevocable damage to the print head.

Remove the cleaning template, detach and discard the used cleaning pad then store the components of the cleaning kit
in their original packaging in a dust free, dry environment.

WARNING: Use only genuine Cembre cleaning materials and methods with MG3. The use of any other materials or methods may
cause irrevocable damage to the print head and/or void any remaining warranty.

5.2) Routine cleaning

Keep internal and particularly moving parts free from dust by wiping with a
soft cloth.
To remove stains or residue from external metal and plastic parts, use a soft cloth
just dampened with a neutral detergent.
Remove grease, print and adhesive residue from templates with alcohol cleaner
and a clean, soft cloth.
Do not allow fl uids to come into contact with electrical parts or the ribbon or to
remain on moving parts.
Wipe up all spills.
As much as possible, avoid the ingress of environmental contamination, eg dust,
into MG3. Fit the protective cover when not in use.

5.3) Replace fuses

MG3s electrical circuits are protected against overcurrent by two 2A 250 V
phase and neutral fuses in compartment (10) located at the back of MG3.
Replacement fuses must have exactly the same characteristics as the ones replaced.
– Disconnect MG3 from the mains supply before opening fuse compartment (10).
Ensure fuses and compartment are correctly relocated before reconnecting the mains supply.
Markingenius MG3 is guaranteed for one year against inherent faults and defects.
The print head is classed as a consumable and not covered by the guarantee.
The guarantee is void if parts used are not Cembre original ones.
