Stylus C40UX/C40SX/C20UX/C20SX Revision A
Operating Principles Overview 29
Also, when replacing ink use this lever to confirm whether the cover cartridge is open
or closed.
There are separate replacement positions for replacing the Black and Color ink
cartridges. If the cover cartridge is open, the I/C detection plate makes contact with the
HP/IC detection lever, causing the HP/IC sensor to detect a high signal.
Figure 2-7. I/C change position
If a High signal is detected even once, it is regarded as if that ink cartridge was
replaced and the cleaning and ink counters are cleared.
If the High signal is not detected even once, the cleaning and ink counter are not
cleared.
If both the ink cartridges have not been set before carrying out initial filling, the
carriage moves to the position where both ink cartridges can be set, but checking if the
cartridge is open or closed is not done.
If one of the ink cartridges has not been set, the carriage moves to the replacement
position of the ink cartridge that is not set due to one time prevention of the set ink
cartridge.
