Transfer Ribbon

The choice of a suitable transfer ribbon is important for the print quality of your printer as well

as the useful life of the printhead.

CAUTION !

Transfer ribbons of inferior quality may cause premature deterioration of

the printhead !

The ribbon material must be antistatic, because the extremely thin surface coating of the

thermal printhead can be damaged by electrostatic discharge.

Also, the material must be extremely resistant to high temperatures to avoid melting the ribbon

with the printhead.

The heat which arises during printing must be carried off by the label and by the transfer

ribbon itself.  Transfer ribbons of inferior quality are often poor heat conductors.  This may

cause overheating of the printhead in spite of electronic protection.

Poor transfer ribbons also tend to lose parts of the coating which leads to accumulating dirt on

the printhead and the sensors.  With some ribbons the color rubs off and soils the printhead.

All of these effects contribute to poor print quality.

We have carried out numerous tests with many different ribbons and we recommend you use

transfer ribbons made by well-known/ brand manufacturers only.  Depending on the label

material, several transfer ribbons may be suitable.

The quality of print is determined by the right combination of these materials.

The recognition of the transfer ribbon is sensed by the rotation control of the transfer ribbon

unwinder, rather than by photocell sensors.  As a result, ribbons with a thinner coating or those

with a colored coating can be used safely.  To be able to print all labels up to the exact end of

the transfer ribbon, the length of the uncoated trailer is limited.

NOTICE !

When buying transfer ribbons,  make sure that the trailer of the ribbon has a

maximum length of 150 mm.   Also note that the trailer easily can come loose from

the cardboard core.
