Abstract
Printer ink-drop detectors are used to detect ink stalagmites forming on a waste ink receiving spittoon. A warning message can be issued so that the stalagmites can be removed before automatic printer shutdown is initiated. Additionally, a record of the ink stalagmite detection can be stored within the printer for later access by service personnel during routine maintenance and/or resource replenishment.
