BJC-5000
5) Ink cartridge detection and identification feature
This printer detects the presence of a BJ cartridge by the two resistance values of
TOP (pin 9) and DIODEA (pin 10) of the cartridge signal contacts. When the
resistance value of TOP is 750
decides that the cartridge is installed. When the resistance values of these pins do
not comply with the above values, the printer decides that the cartridge is not
installed.
When the printer detects the BJ cartridge, the installed BJ cartridge is identified
(black, color, or photo BJ cartridge) based on ID0 (pin 11), ID1 (pin 12), and INKS2
(pin 13) of the cartridge signal contacts.
If the printer is turned on without the BJ cartridge (for example, if a user turns on
the printer immediately after unpacking the printer), the carriage automatically
moves to the cartridge replacement position regardless of its previous position. Also,
if the printer is on and the cartridge is removed without replacement, an BJ
cartridge not installed error will occur.
