Sensor Operational Check (Function Code 32) - Brother DCP130C Service Manual

9.4.8 Sensor Operational Check (Function code 32)

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
- Head thermistor (in the head driver chip)
- Casing internal temperature thermistor (in the complex IC)
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.

IK Black ink cartridge sensor
IY Yellow ink cartridge sensor
IC Cyan ink cartridge sensor
IM Magenta ink cartridge sensor

LK High yield ink cartridge sensor*
TH Casing internal temperature thermistor

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.
