Page 22: Adjusting The Brake At The Label Unwinder
Adjustments Adjusting the Brake at the Label Unwinder The brake (9) at the label unwinder is switched on and off by the movement of the swing arm (2). The correct adjustment of the switching point guarantees an accurate label transport and a high positioning accuracy of the peeled labels. -
Page 23: Adjusting The Label Run
Adjustments Adjusting the Label Run Over an eccentric on the 3. deflection roller (5) it's possible to change the angle between roller and chassis and so the direction of the material (2) run. The label material (2) must so run that the material edge touched softly the paper run edge (1) of the chassis. -
Page 24: Adjusting The Printing Mechanism
Adjustments Adjusting the Printing Mechanism Major adjustment of the printing mechanism beyond format-based settings is only required if the printhead assembly has been removed or parts in this area have been replaced. Excluded from this is the replacement of the printhead, after which readjustment is generally not required. -
Page 25: Adjusting The Printhead Position
Adjustments 5.4.2 Adjusting the Printhead Position In order to achieve the best possible print image the following printhead settings are necessary: • Align the heating line with the highest point of the print roller. Density of the print image is the greatest at this point. -
Page 26: Adjusting The Printhead Pressure
Adjustments 5.4.3 Adjusting the Printhead Pressure The printhead pressure can be changed with the screws (1a) and (1b) at the inside and outside of the printhead. Increasing the head contact pressure leads to an improvement of the print image density on the corresponding side and to a shifting of the ribbon feed path in the corresponding direction. -
Page 27: Adjusting The Transfer Ribbon Feed Path
Reset the Heat level to 0 in the printer configuration Configuration Manual. Recheck the setting with the test function Test grid ( Configuration Manual) or a similar print pattern. When using standard cab media, the test printout must show lines with sharp contours and black areas without any parts missing. -
