3. Black Panel (Changing Black Panel values is not recommended.):
• Black Panel Speed (mm/s): These parameters determine the speed of the receptor
movement during printing for black printing and overlay printing. This value should
always be set to 25.
• Black Panel Compensation (%): If a line of black dots is printed along the card
motion axis, the heating element (pixel) in question does not cool down completely
between adjacent dots. Without compensation, the steadily increasing residual heat
would cause the printed dot to increase noticeably in size (“bloom”), below left.
Properly compensated, the dot size is reasonably constant, below right.
4. Overlay Panel (Changing Overlay Panel values is not recommended.):
• Overlay Panel Speed (mm/s): These parameters determine the speed of the receptor
movement during printing for black printing and overlay printing. This value should
always be set to 25.
• Overlay Panel Compensation (%): If a line of black dots is printed along the card
motion axis, the heating element (pixel) in question does not cool down completely
between adjacent dots. Without compensation, the steadily increasing residual heat
would cause the printed dot to increase noticeably in size (“bloom”), above left.
Properly compensated, the dot size is reasonably constant, above right.
5. Printhead:
• Printhead Resistance (Ohms):
This number is located on a sticker on the printhead cover and on the label applied to
each printhead. The printhead resistance is also written on the inspection report
shipped with each printer.
• Printhead Position Adjust: This setting controls printhead pressure; also see
Printhead Position (Height/Pressure) Adjustment on page 133.

Note • The term Overlay Panel refers to the second Black Panel or the first Uv Panel.
Important • If you replace the Printhead, change this value to match the resistance of the
replacement printhead. The numbers must be the same for the algorithms to work properly.
