Setting Printhead Resistance
This function allows you to change the setting for the printhead resistance. The
setting (A-H) must match the letter stamped on the heatsink in back of the
printhead. This is visible only by removing the L cover (operator panel) of the
printer. Only a trained service representative may remove this cover.
Caution:
The DIP switches are set at the factory to predetermined settings and
should generally not be changed. If you must change the settings, do so carefully
to avoid changing other functions. Run the print test to see what the current
selection is for this function. See “Testing The Printer” On Page 23.
1. Turn the power off.
2. Turn the printer over and note what the current DIP switch settings are.
3. Set the switches to the settings in the table that match the letter stamped on
the heatsink in back of the printhead.
