Align the two circular recess of the print head bracket to 
the two springs attached to the top cover frame. At the 
same time, fix the fulcrum shaft of the print head bracket 
to the hooks. While pressing the print head, slide the side 
tab upwards to lock the print head assembly in place.

Close the Top Cover.

Restore power, reload media, reset the head counter and 
perform a test print to ensure that the print head is 
connected properly.

Make sure the printer is turned off, and remove the power 
cable. 

Lift the Top Cover.

Pull the lever on the middle of the ribbon unit downward to 
pull out the ribbon unit. Then, simply let down the ribbon 
unit. There is a stopper midway through its movement 
range that will prevent the ribbon unit from snapping down.

On the right side of the ribbon unit, slide the print head 
release lever 

 to unlock the print head assembly. Move 

the whole print head assembly downward. 

The cable connectors (circled) at the rear of the print head 
is now exposed. Pull the print head downward, then gently 
disconnect the defective print head from the cable connec-
tors. 

Carefully connect the cable connectors to a replacement 
print head. The white cable should be connected to the left 
connector while black cable should be connected to the 
right connector. The connectors are keyed so that they can 
only be inserted in the correct orientation.

While handling the print head, be careful not to scratch the 
printing surface of the print head. Scratching the surface will 
cause permanent and irreparable damage that is not covered 
by the warranty!
