Page 16: Adjustments
Adjustments Measuring and Adjusting the Winding Torques The rewinder for the transfer ribbon and the internal rewinder are coupled with slipping clutches to the rewinder drive. The unwinder of the transfer ribbon is braked with slipping clutches during printing. The correct setting of the torques of these slipping clutches is necessary for: •... - Page 17 Adjustments The set values for the winding torque and the resulting pulling force at the test collar are: Slipping clutch at Measurement Direction of rotation Winding torque M Pulling force F Ribbon rewinder against winding direction 13,5 - 14,4 Ncm 4,3 - 4,8 N in winding direction 2,1 - 3,0 Ncm...
- Page 18 Adjustments Internal Rewinder Measurement of the winding torque at the internal rewinder occurs by determining the pulling forces with a cord wrapped around the rewinder. The physical relation between the torque and the pulling force is: F= M / r Pulling force [N], Winding torque [Ncm], Radius of the rewinder (38 mm)

Adjustments 3.1.2 Adjusting the Winding Torques The winding torque of a winder can be changed at the knurled ring of the respective slipping clutch. The numbers on the knurled ring stand for the value of the winding torque: • 1: Lowest winding torque •... -
Page 20: 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 21: Adjusting The Printhead Position
Adjustments 3.2.2 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 22: Adjusting The Printhead Pressure
Adjustments 3.2.3 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 printhead pressure leads to an improvement of the print image density on the corresponding side and to a shifting of the ribbon feed path to the other side. -
