Page 18: Adjustments
Adjustments Measuring and Adjusting the Winding Torques The rewinders for the transfer ribbon and the internal rewinder are coupled with slipping clutches to the rewinder drive. The unwinders of the transfer ribbon are braked with slipping clutches during printing. The correct setting of the torques of these slipping clutches is necessary for: •... - Page 19 Adjustments Figure 17 Measuring the winding torque at the transfer ribbon rewinder (left) and unwinder (right) Danger! Risk of death via electric shock! Before opening the housing cover, disconnect the device from the mains supply and wait at least one minute until the power supply unit has discharged.
- Page 20 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)

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 (1). 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 Feed
Adjustments Adjusting the Label Feed The label material (2) must run touching guide faces (1) of the chassis. Figure 22 Material at the guide faces If the material drifts sidewards the pinch rollers (4,7) of the transport system and the backfeed system can be adjusted. -
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 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. -
Page 27: Adjusting The Transfer Ribbon Feed Path
