    Operators Manual ALX 720 10.3.3 APSF sensor For the APSF function (Automatic speed follower) a rotary encoder has to be installed. For optimum labelling accuracy the rotary encoder should be selected so that it produces one pulse for every 0.125 mm of product movement. The connection of the encoder should be done with a shielded cable.

    Operators Manual ALX 720 11.1 Label Material The printer is equally suitable for thermal transfer printing. Three factors are to be taken into account when choosing the material: Abrasive behaviour of the surface structure Properties with respect to chemical reaction on print-colour transfer Temperature required for colour- transfer If the material is extremely abrasive, the print head is faster worn as usual.
