Setting Printhead Resistance
This function changes the setting for the thermal printhead resistance. The setting must
match the character (A-D, 0-3) stamped on the heatsink in back of the printhead, visible by
removing the top cover of the printer. See the 7156 Service Guide for information on
removing the top cover. This procedure should only be performed by a trained service
representative.
Caution:
The DIP switches are pre-set at the factory and should generally not be changed.
If you must change them, do so carefully to avoid changing other functions. Run the print
test to print the settings for this function. See “Print Test” later in this chapter.
Note:
The operator panel may differ depending on the model. To put the printer on- or
off-line, use a paper clip or other pointed object to depress the plunger (in place of the On
Line button) on models with that item.
1. Open the front cover and set the DIP switches to match the character stamped on the
heatsink in back of the printhead.
Switch 7 is always Off. Switch 8: On = knife, Off = non-knife
