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.
