d. At the Select Function window, press the down arrow once and select [
Setup
Printer
].
e. Next select [
Print Settings
].
f. At the Print Settings window, press the down arrow seven times and select
[
Head Resistance
].
g. Use the up and down arrows to change the Current Value to closely match
the resistance value you had recorded from the new Printhead noted in Step
2. (
Note:
The value on the display will change in 50-ohm increments.) Adjust
the value as closely as possible.

i. Print a test card by selecting
Menu> Printer> Menu
from the LCD display,
then [Print Test Image] and then select the proper ribbon type.
(
Note:
This is to confirm that the new Printhead Assembly is functioning properly.) If the test
print looks good (and it is consistent with the overall position and darkness of the test print
from the old Printhead), the Printhead installation is complete. If you notice a problem with the
test print, please review the troubleshooting suggestion below.
Troubleshooting Suggestions
It may be necessary to make some minor adjustments to the Printer after a new
Printhead is installed. The
TOF
(Top of Form),
EOF
(End of Form),
Image Darkness
or
Image Position
may require adjustment if the Ribbon is breaking, the image is not centered or
if the image is not the proper darkness.
Print TOF and Print EOF Alignment
The following two procedures must be performed as a single alignment process:
Print
TOF
and
Print EOF
. The goal of these procedures is to align the printed image precisely with
the edges of the card, as shown below. Notice that when aligned properly, the test print’s
Alignment Arrows will fall just inside the edges of the card.
(
Note:
The tips of the arrows may not be visible. The importance of this adjustment is to
ensure that there is equal distance between the image and the edges of the card.)
