a. Sensor check
Condition of the sensors and switches (total number: 11) listed below can be checked when the
paper deck is in the sensor check mode.
Registration paper sensor (PS1)
Paper-level detection switch 1 and 2
Paper jam sensor (PS2)
(SW601 and SW602)
Tray paper-out sensor (PS3)
Paper-size detection switch 1, 2, 3, and 4
Paper surface sensor (PS4)
(SW701, SW702, SW703, and SW704)
Door sensor (PS5)
The checking procedure is as follows.
1) Turn OFF the printer.
2) Sets the test switches to the sensor check mode.
3) Depending on the sensor to be checked, choose the checking method from the following three
cases.
a. Checking the registration paper sensor (PS1), the paper jam sensor (PS2), and the door sen-
sor (PS5). •••••••••• Open the feed cover, and then the power ON.
b. Checking the tray paper-out sensor (PS3) and the paper surface sensor (PS4).
•••••••••• Remove the right cover, and turn ON the power.
c.
Checking the paper-level detection switch 1 and 2 (SW601 and SW602) and the paper-size
detection switch 1, 2, 3, and 4 (SW701, SW702, SW703, and SW704).
•••••••••• Remove the rear cover, take off the board fixing plate, and then the power ON.
4) Check if the LED lights up when you move the switch or the sensor lever of the sensor you
wish to check.
Do not move more than one sensor lever at the same time. Move them one by one to find
which sensor is faulty. Also, be sure not to touch the switches with hand directly.
5) If the LED does not light, the sensor or the switch is faulty.
Note:
You can turn ON the power by turning ON either the printer or the stand alone mode
switch.
