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: Winder Measurement Direction of rotation Winding torque M Pulling force F Ribbon rewinder against winding direction Hermes Q2 10,2 - 10,8 Ncm 3,4 - 3,6 N Hermes Q4/Q4.3/Q6.3 12,9 - 14,4 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 (3,8 cm)

Page 19: Adjusting The Winding Torques
Adjustments 5.1.2 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 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 (1). The correct adjustment of the switching point guarantees an accurate label transport and a high positioning accuracy of the peeled labels. -
Page 21: Adjusting The Label Feed Path
Adjustments Adjusting the Label Feed Path The inner edge of the label liner must softly touch the paper guiding edges (1) of the chassis during the transport. The direction of the material (2) run can be adjusted by the eccentric on the deflection roller (3). Figure 16 Adjusting the label feed path 1. -
Page 22: 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 23: Aligning The Printhead To The Print Roller
Adjustments 5.4.2 Aligning the Printhead to the Print Roller In order to achieve the best possible print image the following printhead settings are necessary: • Setting the parallelism of horizontal lines and the edge of the label. • Aligning the heating line to the top of the print roller. This is the position with the highest print image density. HERMES Q without automatic ribbon saver HERMES Q with automatic ribbon saver Figure 18... -
Page 24: 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 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 opposite side. -
