Adjusting the Ribbon Saver

The ribbon saver reduces the consumption of transfer ribbon amongst others by lifting the printhead while feeding
blank label areas. The printhead will be lifted by eccentrics (6) which are controlled by a clock wheel (2) and an
optical sensor (1).
A misaligned clock wheel can cause a reduction of the saver effect in the saver phase or a deterioration of the print
image and a stagnant ribbon transport in the print phase.
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.

1. Unplug the printer from the electrical outlet.
2. Remove the cover.
3. Turn lever (7) clockwise to lock the printhead.
4. Loosen the screws (4) at the clock wheel.
5. Turn axle (3) in such a way that the eccentrics (6) lift the
printhead via the ball bearings (5) at most
 Figure 31 right side.
6. Adjust a gap of ca. 1 mm between flange (2a) and the
edge of the sensor housing (1) by turning the clock wheel
 Figure 31 left side.
7. Tighten screws (4).
8. Turn axle (3) in such a way that there is a gap of 1 mm
between flange (2b) and the other edge of the sensor
housing  Figure 32 left side.
9. Check the distance between ball bearing (5) and
eccentric (6) with the 0,1 mm gauge (8).
10. Mount cover.
