Maintenance
Printhead Position
Adjusting the printhead position moves the printhead with respect to the platen for 
optimum print quality. If satisfactory print quality cannot be achieved or can be achieved 
only with higher than normal darkness settings or higher than normal printhead pressure, 
the printhead may not be in the proper position. 
Refer to 
 for location of adjustment screws.
Figure 4-20.   Adjust the Printhead 
1. Print test labels using the Pause Key Self Test.
2. Enter Configuration Mode and set the darkness to achieve as close to optimum print 
quality as possible. 
3. Refer to 
Figure 4-20
. Loosen the four screws at the top rear of the print mechanism.
Caution:
Other than printhead pressure, printhead adjustments rarely need to be 
performed, even after replacing the printhead. These adjustments should be 
performed only by a qualified technician who has been specifically trained. Do 
not perform these adjustments unless you have been trained to do so.
Note • The ribbon take-up spindle
is not shown in this illustration.
Note • Loosen four screws
before adjusting printhead.
