Maintenance Cartridge

Overview
a) Maintenance Cartridge
Maintenance Cartridge can contain a maximum of 450 ml of waste ink. The quantity of collected waste
ink is memorized in EEPROM mounted on Maintenance Cartridge.
b) Detection of waste ink in Maintenance Cartridge
The quantity of waste ink collected in Maintenance Cartridge is measured according to the dot count.
When the quantity of waste ink reaches approximately 360 ml, Maintenance Cartridge Warning Lamp
on Operation Panel blinks to indicate that Maintenance Cartridge is nearly full. Even when a warning
message is displayed, printing can be continued.
When the quantity of waste ink reaches approximately 450 ml, Maintenance Cartridge Warning Lamp
on Operation Panel stops blinking and stays lit to indicate that Maintenance Cartridge has become full.
When a dot count error occurs, Maintenance Cartridge Leakage Sensor detects that waste ink in
Maintenance Cartridge is full.
Even when it is determined that Maintenance Cartridge is full according to the dot count, the current
print job is executed to the end.
When it is determined that Maintenance Cartridge is full according to the result of detection by
Maintenance Cartridge Leakage Sensor, Printer stops operating even if printing is in progress.
Once the full state of Maintenance Cartridge is detected, Printer will not operate until Maintenance
Cartridge is replaced.
