Solenoid, photosensors, and switches
The following figure shows the locations of the solenoid,
photosensors, and switches.
Figure 18.
Solenoid, photosensors, and switches
1
Paper delivery sensor (PS921) senses when paper has
successfully moved out of the fusing area.
2
Power switch.
3
Paper top sensor (PS911) detects the leading and trailing edges
of the paper. It synchronizes the photosenstive drum and the top
of the paper.
4
Engine test switch (SW201); see “Engine test” on page 156 for an
explanation of the switch.
5
Door-open switch (SW301) detects whether or not the printer
door is closed and the print cartridge is present. Printing cannot
continue until the printer door is closed and the print cartridge is
in its correct position.
6
Solenoid (SL001) enables the pickup roller.
7
Paper detection sensor (PS931) senses when paper is in the
main input tray or the priority input tray.
