Page 19: Adjustments
Adjustments Measuring and Adjusting the Winding Torques The rewinder for the transfer ribbon is coupled to the main drive using a slipping clutch in. The supply hub of the transfer ribbon is braked with a slipping clutch during printing. The correct setting of the torques of these slipping clutches is necessary for: •... - Page 20 Adjustments The set values for the winding torque and the resulting pulling force at the test collar are: Slipping clutch on Direction of rotation Winding torque M Pulling force F Ribbon take up hub against winding direction 12,9 - 13,5 Ncm 4,3 - 4,8 N in winding direction 2,1 - 3,0 Ncm...

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 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: Adjusting The Printhead Position
Adjustments 5.2.2 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 24: Adjusting The Printhead Pressure
Adjustments 5.2.3 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 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 to the opposite side. -
Page 25: Adjusting The Transfer Ribbon Feed Path
Adjustments 5.2.4 Adjusting the Transfer Ribbon Feed Path You can adjust the transfer ribbon feed path by changing the head contact pressure and adjusting the transfer ribbon deflection. Increasing the head contact pressure with the screws (3a) and (3b) shifts the ribbon feed path in the corresponding direction. The skew of the transfer ribbon deflection is used to suppress wrinkles in the transfer ribbon feed path. Wrinkles which cannot be remedied with the skew of the transfer ribbon deflection can be suppressed by bowing the printhead. Attention! The printhead assembly can be damaged when bowing the printhead. Turning the adjustment screw (1) too hard can cause damage to the printhead assembly. -

Page 28: Adjusting The Magnetic Clutch
Adjustments Adjusting the Magnetic Clutch A misaligned magnetic clutch can cause a very high and not adjustable torque at the ribbon supply hub. The distance between chassis of the magnetic clutch (2) and the armature disk (3) must be 0.1 mm . Danger! Risk of death via electric shock! ... -
Page 29: Adjusting The Ribbon Saver Mechanics
Adjustments Adjusting the Ribbon Saver Mechanics The saver automatic reduced the consumption of color ribbon, because in case of the saver mode the movement will interrupted by lifting the printhead. This operated by a eccentric, which is controlled by a light sensor. A failure in adjustment is possible if the transport of the ribbon is stopped generally or it will make all movements like the label material. -
Page 30: Configuring The Power Source For The Oem I/O Interface
Adjustments Configuring the Power Source for the OEM I/O Interface The OEM I/O interface can be used with the internal or an external 5 V power source. When the module is delivered the interface is configured for the internal power source of the module. In order to isolate the interface from the internal power source, an external voltage must be connected. To adapt the power source mode the setting of the jumpers at JP4 and JP5 must be altered. -
