Printing
Printing begins with the same process described in the media positioning except
the media is not unloaded. Also the clamp-close solenoids remain energized to
hold the leading edge of media to the drum. The drum incrementally steps
forward to allow the shutting printhead to print the image in swaths upon the
paper. As the drum rotates far enough that the paper clamp reaches it home
position, and the leading edge of the paper is now under the clamp rollers, the
clamp-close solenoids de-energize to release the leading edge of the paper. The
Y-axis motor continues to rotate the drum, moving the friction-fed media, as the
printhead prints.
