a) Maintenance cartridge
The maintenance cartridge can store waste ink.
b) Detection of waste ink in maintenance cartridge
The quantity of waste ink in the maintenance cartridge is measured by counting dots.
When the quantity of the waste ink reaches approximately 80% of the cartridge capacity, the warning message "Check maint cartridge capacity" is displayed to tell
that the maintenance cartridge is nearly full.
Printing may continue even when the warning message is displayed.
When the quantity of the waste ink reaches approximately 100% of the cartridge capacity, a replacement prompt error message is displayed, telling that the main-
tenance cartridge is full.
When the printer determines that the maintenance cartridge is full, it shuts down even while it is printing.
The printer will remain inoperable until the maintenance cartridge is replaced.
MEMO:
The maintenance cartridge houses EEPROM, so that main controller PCB can control the status of the maintenance cartridge by writing to and reading from the
EEPROM content.
There is no need to initialize the counter information, therefore, when the maintenance cartridge is replaced.
