An exact fit ribbon cartridge enables easy and user-friendly replacement and does not jump out during printing. Perfect harmonization between printer mechanism and ribbon transport means uniform color distribution, which in turn ensures a clean and pleasant appearance and also makes ribbon tightening a thing of the past. In the selection of ribbon fabric and mesh thickness, Epson naturally pays particular attention to the special characteristics of the print head to ensure that the ribbon does not fray and that there is no chance of it sticking. In addition, you avoid expensive repairs as a result of defective print heads and breakdowns in the cash register. In the same way, Epson attaches great importance to the choice of ink with which the ink ribbon is soaked: print quality, even color distribution along the length of the ink ribbon and protection of the print head's pins against mechanical stress and chemical contamination are the important criteria that affect quality and perfect design.
