The $100 Canon Pixma MP470 is an entry-level inkjet all-in-one that produces high-quality prints at decent print speeds (though text prints are slow). This multifunctional printer produces the best text and graphics prints. The black-and-silver body of the printer measures 17.7 inches wide, 13.9 inches deep, and 6.7 inches tall. The silver scanner lid conceals an A4-size flatbed scanner. The paper handling system of this printer is simple. Next to the output tray is a small door that conceals two memory card slots. The slots accept most common types of memory cards, though some require an adapter (which is not included).
The control panel of this cheap printer is basic, though well-organized. The Pixma MP470 uses a two-tank ink system: one black and one tricolor. Using the large tanks for best value, a black-only print costs about 5.6 cents, while a four-color page costs about 13.7 cents. The cheap Canon Pixma MP470 offers copy, scan, and photo print features.
The cheap Canon Pixma MP470 is slow with text prints, but quick with graphics and 4×6 photos. Its scans are right in line with everyone else’s. It printed text at a pokey 5.45pages per minute. The Pixma MP470 produced color graphics prints at a rate of 2.10ppm. The Canon produced grayscale scans at a rate of 4.60ppm and color scans at a rate of 4.49ppm. The text print is dark, sharp, clean, and legible down to very small point sizes. The graphics print is also sharp and detailed. Colors were true and gradients were smooth.

Ink run-out detector, ink cartridge and ink jet recording apparatus Abstract
An ink cartridge is provided with an ink run-out checking section having an air-curable curing agent. When the ink contained in the ink cartridge is reduced to expose the checking section to air, the curing agent is cured. A movable pushing member pushes a deformable film of the checking section. If the curing agent is uncured, the movable pushing member stops at a position where the deformable film is deformed into the curing agent. If the curing agent is cured, the deformable film cannot deform, so the movable pushing member stops at a position just in contact with the deformable film. Based on the position of the movable pushing member, a controller judges whether the ink remains or not, as well as whether the ink cartridge is mounted or not.
