When to Replace the Maintenance Cartridge (iPF9400) (iPF9400S)
Solution
Replace or prepare to replace the Maintenance Cartridge in the following situations.
When the Maintenance Cartridge is almost full, the Message Lamp is lit and "The level is low" is shown on the Display Screen. You can continue to print, but check the remaining Maintenance Cartridge capacity and prepare to replace the Maintenance Cartridge with a new one. (See "Checking the Remaining Maintenance Cartridge Capacity (iPF9400) (iPF9400S).")
Printhead cleaning, Printhead replacement, and preparations to transfer the printer deplete much of the Maintenance Cartridge capacity. (In particular, preparing to move the printer depletes a lot of the capacity.)
Check the remaining Maintenance Cartridge capacity before this maintenance and replace the Maintenance Cartridge if necessary.
When the Maintenance Cartridge is almost empty, the Message Lamp lights, a message to replace the Maintenance Cartridge is displayed on the Display Screen, and you cannot print. Replace the Maintenance Cartridge with a new one.
