Device for determination of the amount of ink remaining in multiple ink reservoirs in an inkjet printer

摘要

Device comprises electrical connection means (129) between the printer chassis and the carriage (60) carrying the plates (121a-121e) of the capacitors corresponding to each print reservoir (112a-112e). Hence each capacitor is charged and connected via a common contact (131) to an oscillator (118). Each reservoir has a predetermined position in the carriage (60) for the reservoirs. An Independent claim is made for a printer using the printer reservoir mounted in a carriage that moves up and down support guides during printing.
