ABSTRACT:
A printer and facsimile apparatus using the printer capable of detecting residual ink in an ink cartridge with higher precision by eliminating influence of ripples of ink surface due to the movement of an ink cartridge or influence of noise. Reflective type photosensor 11 detects residual ink in ink cartridge 9, and the detection result is current/voltage-converted. Smoothing circuit 152 smoothes the converted detection result including the influence of the trembles of ink surface and the mixing of noise. Then the smoothed voltage is A/D converted and forwarded to processing by CPU 101.
