• Taper tension (%): In winding systems, decreasing the unwinder tension while the
rewinder radius increases is called taper tension control. This makes unwinder tension
tighter while releasing some tension from the rewinder as the rewinder roll diameter
increases, thus avoid slipping of the label media. Minimum value is 0%, maximum
value is 10%. Recommended is 5%.
• Mid job maintenance distance (m): Setting mid-job maintenance frequency in printed
linear meters. Mid-job maintenance is a full printhead maintenance during processing
a print job to preserve the best print quality.
Note: Actual value is always displayed in the status bar on the screen.
• KWS mode: KWS = Keep Wet Spitting.
KWS is a function to protect the 70,400 printhead nozzles from dehydration. In practice
it means that during printing all nozzles fire some ink, even the nozzles which do not
take part effectively in printing. As a result, tiny (almost microscopic) dark spots of ink
can be seen on printouts, especially when the background of the printed image is light
in color. When those tiny spots are not acceptable from a print quality point of view, this
function can be reduced or switched off completely.
