Note: Be sure to note the orientation of the flat cable, paying close attention to
the blue stripe on each end of the cable and the length of each leg of the
cable.
Notes:
1. Notice that one end of the cable is longer than the other. The longer end should
be installed into the printhead.
2. Do not reverse flip the cable during installation.
3. An improperly installed cable will result in no communication between the logic
card and the thermal print head.
To replace the thermal printhead flat cable, complete the following step:
1. Orient the cable so the longest end is facing up and the blue stripe facing away
from you.
2. Slide the long end of the cable into the printer unit just under the printhead
mount.
3. Route the rest of the cable through the printer unit frame toward the logic card.
4. Connect the cable to the printhead; then install the printhead (see “Removing
the thermal printhead” on page 58 for information on how to replace the
printhead).
5. Connect the opposite end of the cable to the logic card; then replace the logic
card (see “Removing the logic card” on page 60 for information on how to
replace the logic card).
