Managing a service cartridge for an inkjet printhead

A method for managing a service cartridge for an inkjet printhead, wherein the service cartridge comprises a printing fluid storage container for receiving printing fluid discharged from the printhead and a web wipe intended to be advanced a predetermined length for performing a wiping operation on the printhead, the method comprising:

• monitoring, from a predetermined starting point, the amount of discharged printing fluid and the amount of consumed web wipe;
• determining that the printing fluid storage container is in an overflow risk status when the ratio of the amount of discharged printing fluid to the capacity of the printing fluid storage container is higher than the ratio of the amount of consumed web wipe to the total length of the web wipe, and is in a no overflow risk status if this condition is not met;
• if the overflow risk status is determined, advancing the web wipe, in a subsequent wiping operation, a length that is higher than the predetermined length;
• and
• if the no overflow risk status is determined, advancing the web wipe, in a subsequent wiping operation, a length equal to the predetermined length.
