Remove the 110PAX4 Print Engine from the Applicator
Note • Retain all parts removed during disassembly, unless otherwise directed.
Electrostatic Discharge Caution • Observe proper electrostatic saf e ty
precautions when handling any static-sensitive components such as circuit
boards and printheads.
1.See Figure . Turn Off (O) the print engine and disconnect the AC power cord and
interface cables.
2.Open the front cover, unlatch the printhead lever, and remove media and ribbon
from the print engine.
3.Close and latch the printhead lever, and then close the front cover.
4.See Figure . Remove the four corner mounting screws securing the print engine to
the applicator
5.Leave the center mounting bolt until last.
Note • The keyh ole and the center mounting bolt are designed to support the
print engine and assist in installing and removing the four mounting screws.
6.To remove the print engine from the applicator, lift the print engine off the center
mounting bolt and place on a workbench.

Note • Prior to installing the new pri nthead, make a not e of the resist ance val ue
located on the right side of the manufacturer’s label. The “R” valu e is given in
Ohms.
Caution • An improperly seated printhead data or power cable may cause the
printhead to generate excessive heat and/or a false HEAD COLD message to
display while the printhead is hot enough to cause severe burns.
1.Se e Figure 3. Reconnect the printhead power cables to their appropr iate co nnector s.
Seat both connectors firmly into place.

reverse conversion.
7.See Figure 9. Place the new stepper motor pulley on the shaft. Make sure there is a
3/16 inch (4.76 mm) gap between the pulley and the stepper motor. Tighten the set
screws on the two flats on the stepper motor shaft.
8.See Figure 10. Place the new belt around the stepper motor pulley. Make sure the
stepper motor standoff is positioned properly over the st andoff pins and place the
stepper motor on top of the stepper mo tor sta ndof f. Rein sta ll and ti ghten the stepper
