Corrective Maintenance—Print Quality Adjustments

Open the print engine cover.

Refer to 

 and remove the two access caps in the printhead mounting extrusion.

Adjust the inside toggle 2 in. (50.8 mm) from the wall to the inside edge of the inside 
toggle bracket and 5 in. (127 mm) from the wall to the inside edge of outer toggle bracket.

. Compress the toggle spring by turning the lower knurled nut clockwise 

until the distance from bottom of the toggle positioning bracket to top of the lower knurled 
nut equals 0.24–0.39 in. (6–10 mm).

Perform the PAUSE Key Self Test by pressing PAUSE while turning On (l) the print 
engine.

Print a PAUSE Key Self Test by holding down PAUSE while turning On (l) the print

The order in which the following adjustments are performed depends on the print 

quality of the labels printed during the previous Pause test.

The first two print quality adjustments (parallelism and balance) must be completed prior to 
attempting to locate the optimum printhead position. As with the other adjustments, 
parallelism and balance adjustments are interrelated. Adjusting one may have an effect on the 
position of the other.

Excessive toggle pressure will lead to increased printhead wear and decreased printhead life. 
Increased printhead life is possible by combining minimum toggle pressure and optimum 
printhead position over the platen roller.
