Cleaning Cleaning by the Operator The following cleaning work is described in the “Thermal Transfer Printer cleaning instructions“ TE document number: 411-121020. • cleaning the device • cleaning the printhead • cleaning the print roller • cleaning the label sensor...
Cleaning Cleaning the Label Sensor Fig. 1 Cleaning the label sensor Fig 2 Removing the label sensor Danger! Risk of death via electric shock! X Before opening the housing cover, disconnect the device from the mains supply and wait at lease one minute until the power supply unit has discharged.
Replacing Assembly Units Tools X Do not use any worn of damaged tools. X Only use tools and testing devices that are suitable for the task at hand. special tools: • Test collar for transfer ribbon winder (5534199) Standard tools: •...
Replacing Assembly Units Replacing the Printhead Replacing the Printhead The printhead of the printer can be replaced without the need for fine adjustment. The printhead must be replaced if worn or when switching to a printhead with higher or lower resolution. For better identification, the print heads have a label stating the printer type and resolution.

Replacing Assembly Units Removing the printhead 1. Turn lever (10) counterclockwise to lift the printhead. 2. Remove labels and transfer ribbon from the printer. 3. Remove Allen key (11) from its retainer. 4. Lightly keep printhead mounting bracket (9) on the print roller with one finger and screw out screw (8) with the Allen key and remove it and the washer.
Replacing Assembly Units Replacing the Slipping Clutches The rewinder for the transfer ribbon and the internal rewinder are coupled to slipping clutches in the main drive. The supply hub of the transfer ribbon is braked with a slipping clutch during printing. Change the slipping clutch when it can no longer be set ...

Adjustments 4.1.2 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 •...
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.
Adjustments 4.2.2 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.
5. For TE3124 /TE3112 printer move the plunger to the printer standard position for the media being printed operator's manual and repeat the test print. Possibly rerun procedure and adjust again.
Adjustments 4.2.4 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.
Adjustments Adjusting the Belt Tension at the Main Drive Motor Danger! Risk of death via electric shock! X Before opening the housing cover, disconnect the device from the mains supply and wait at lease one minute until the power supply unit has discharged. Attention! The toothed belt could be damaged if adjustment is carried out improperly.
Adjustments Adjusting the Head Switch The head switch prevents printing from occurring when the printhead is open. Adjust the head switch if the error message Head open appears in the display even though the printhead is locked. Danger! Risk of death via electric shock! X Before opening the housing cover, disconnect the device from the mains supply and wait at lease one minute until the power supply unit has discharged.
