Abstract

PURPOSE:To enable detection of the quantity of ink being consumed in a replaced ink cartridge, by containing a material which can absorb waste liquid in a container formed at least partially with transparent or semitransparent member, then irradiating said material with light, thus detecting the presence of ink liquid. CONSTITUTION:Waste liquid discharged through a discharge pipe 42 is absorbed by an absorbing material and spreads in the direction of a waste liquid detector 44 from a discharge pipe take-in position. When the waste liquid reaches the position of the detector 44, the quantity of light being received by a photosensor varies, then said variation is converted into an electrical signal and taken out as a waste liquid detection signal. Since the quantity of ink being used and the quantity of waste ink are in proportional relation, in general, the quantity of ink being consumed in an ink cartridge can be roughly judged by detecting the quantity of waste ink. Since the quantity of waste ink being stored in a waste tank 46 is proportional to the distance from the discharge pipe take-in position to the position where the waste liquid has spread, the waste liquid detector 44 is arranged at that position so as to detect the quantity consumed and indicate the quantity consumed onto an indicator 35.

However, conventional ink usage amount detection devices of this type are configured so that when a new ink cartridge is installed in the printer, the ink usage amount stored in the non-volatile memory is reset to the initial value. If you remove the ink cartridge from the printer or replace the ink cartridge that is in use and then reinstall it, the amount of ink used will be reset to the initial value, and no instructions to replace the ink will be displayed.
There was a problem in that ink waste liquid spilled from the waste liquid tank of the cartridge.
