Display Contrast Adjustment:
This potentiometer is situated close to the connector of "uart1:"
and can be accessed through a small hole in the rear plate. Using
a narrow-tipped screwdriver, turn the screw in either direction
until the text in the LCD display on the printer's front becomes
clearly visible in the prevailing light conditions when viewed
from a normal working position.
