Printhead shutter
The printhead shutter tightly covers the slit glass through which laser beams from the printhead pass to write the
four drums. To prevent the seal glass from becoming dirty, the shutter stays closed except when laser beams
are written onto the drums.
The printhead shutter motor assembly is used to prevent contamination from obstructing the printhead slit
glasses. The printhead shutters for yellow, magenta, cyan and black are opened or closed simultaneously by the
printhead shutter motor assembly.
