Cleaning the Digital Array Printhead and Paper Sensor
Figure 7-1: Cleaning the Digital Array Printhead
A. Printhead
B. Paper Sensor
If the print quality is uneven, it may be due to a dirty printhead. How fre-
quently you must clean the printhead depends on how many ECGs you print
and the quality of and type of paper you use.
If the paper fails to stop at the end of a page, the paper sensor lens may be
dirty.
