a) Cap unit
The cap unit is used to cap the printhead nozzles during capping and cleaning. The portion that touches the face plate is made from rubber. Two caps are arranged
for the printhead (six arrays of nozzles) installed in the carriage.
During cleaning, the caps used for both suction and capping are used to suck ink from the printhead using the suction pump.
During capping, the caps are raised by the purge motor to cover the printhead when the carriage has moved to the home position, thus protecting the nozzles.
