Disclosed is a device for collecting waste ink. The device prevents the collected waste ink from spilling even when the device is inverted. A visual indication that the device is full is provided. Waste ink is regularly generated in ink-jet printers during startup and maintenance procedures. Typical waste collection systems trap waste ink in a reservoir. Surface tension prevents the free waste ink from flowing reliably in small channels. Also, waste ink can sometimes leak from the reservoir, especially if the reservoir is inverted or overfilled. Another type of waste-collection method collects waste ink in an absorbent pad. One implementation transports the ink to the pad through a small channel by means of a mechanical pump.
