Page 44: Adjustment Of Printhead Flat Type Kf
Service Manual Adjustment of printhead Flat Type KF Parallelism An important characteristic for a high quality print is the parallelism of the focal line of the thermal printhead to the pressure roll. Because of the fact that the position of focal line of the printhead depends on fluctuations caused by production, it is necessary to set the parallelism. - Page 45 Service Manual Pressure Note: It is recommended to avoid increasing the printhead pressure because too high pressure damages the printhead res. reduces its life. The pressure is set from the manufacturer according to the specification of the printhead. It is possible to optimise the life of the printhead by selecting the lowest possible setting. Modify the printhead pressure by means of the pressure screws (G).
