 Function
This function allows you to check the following:
- Document front sensor
- Document rear sensor
- Scanner/ink cartridge cover sensor
- Registration sensor
- Purge cam switch
- Black ink cartridge sensor
- Yellow ink cartridge sensor
- Cyan ink cartridge sensor
- Magenta ink cartridge sensor

 Operating Procedure
(1) Enter 3 and 2 in the initial stage of the maintenance mode using the / and OK keys.
If the sensing status are as listed below, the LCD will show "DFDRCVRSCCP1****" and
"IKIYICIMVT LKTH," which can be switched by pressing the Black Start (Mono Start)
key.
Given below is the relationship between the LCD indication, sensor name and sensor status.
LCD Sensors Sensing status
DF Document front sensor*
1
No document detected.
DR Document rear sensor*
1
No document detected.
CV Scanner cover sensor*
2
Scanner cover and ink cartridge cover closed.
RS Registration sensor No recording paper detected.
CC Ink cartridge cover sensor*
2
Scanner cover and ink cartridge cover closed.
P1 Purge cam switch Purge cam switch ON.
IK Black ink cartridge sensor Black ink cartridge loaded (Black ink present).
IY Yellow ink cartridge sensor Yellow ink cartridge loaded (Yellow ink present).
IC Cyan ink cartridge sensor Cyan ink cartridge loaded (Cyan ink present).
IM Magenta ink cartridge sensor Magenta ink cartridge loaded (Magenta ink present).
VT Head thermistor Driver chip temperature within the allowable range.
LK High yield ink cartridge sensor*
3
High yield ink cartridge not loaded.
TH Casing internal temperature thermistor Normal temperature detected.

2
Sensor sharing: Two sensor actuators share a single photosensor (scanner/ink cartridge cover sensor)
so that the sensor acts as a scanner cover sensor and ink cartridge cover sensor. If either the scanner
cover or ink cartridge cover is open, both "CV" and "CC" disappear.
*
3
The "LK" is always displayed even on models not equipped with a high yield ink cartridge sensor.
(2) Change the detecting conditions (e.g., open the scanner cover or insert paper through the
registration sensor or remove the ink cartridges), and then check that the indication on the
LCD changes according to the sensor states.
(3) To stop this operation and return the machine to the initial stage of the maintenance mode,
press the Stop/Exit key.
