16 cab Produkttechnik GmbH & Co KG / Tharo Systems, Inc.Print MediaThe A8 can be operated in direct thermal as well as thermal transfer mode.For direct thermal mode, only use print material with a thermal-reactive coating.The print image is transferred by heating the material at the printhead, causinga reaction on the surface of the paper and, consequently, darkening thematerial.In thermal transfer mode, not only standard paper labels are needed but alsothe thermal transfer ribbon with a color surface. The printout is created byheating the transfer ribbon, causing a transfer of color particles onto the label.A8 allows to regulate the heat level and also the print speed. Thus, the A8offers a wide range of opportunities for usage.The A8 is able to print on labels and continuous paper with a maximum supplyroll diameter of 8 in (200 mm).The minimum core diameter is 3 in (76 mm).The printer can also process fanfold label material.The ability of label edge recognition, which guarantees the precise position ofthe printer output, is accomplished by a moveable photocell. This sensor iscontrolled by the processor of the A8 and ensures recognition for different sortsof material. There is no need for additional electronic adjustment.On the following pages, you will find detailed information and specificationsconcerning suitable materials.If you have any questions, check with your local distributor as not everymaterial can be used for direct thermal or thermal transfer printing.If in doubt, we will perform test prints with your label material to find the bestsuitable transfer ribbon.
