printer toner cartridges – Canon Selphy CP740: photo printer

Filed under: Toner Cartridges — Cheap Ink Cartridges @ 6:55 pm

The $100 Canon Selphy cheap CP740 is an entry-level compact photo printer whose limited onboard feature set reflects its relative position among dedicated 4×6 photo printers. The Selphy CP740 is indeed compact and can be easily slipped into a tote bag or large purse. Canon Selphy CP740 measures 7 inches wide, 2.5 inches tall and 5 inches deep. This cheap printer weighs 2.1 pounds without the ink installed, paper cassette attached, or power brick plugged in; with all of the necessary accoutrements it gets a bit heavier.

A 2-inch color LCD is also embedded right in the surface of the Selphy cheap CP740. On the front edge of this cheap printer are three memory card slots that can accept most common memory cards, though some will require an adapter. There’s also a retractable mini-USB cable for directly connecting PictBridge. The Selphy CP740 comes with a postcard-size cassette and a starter ink cartridge that is good for only five prints (five sheets of paper are also included). Paper and ink are sold together in packages, and the ink is calibrated for the number of sheets in the package.

Canon Selphy CP740 produces 4×6 photos at a rate of 0.92 pages per minute, faster than many of the single-function and multifunction inkjet printers. Standard 4×6 test print produced on the Selphy CP740 showed sharp, clear details and pleasing skin tones. The colors looked a bit cool, and we’d prefer a brighter, warmer look. But overall, the Selphy CP740 produced prints that were good enough for casual home users.

Ink cartridge and ink-jet printer Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an ink cartridge which supplies an ink to an ink-jet head for performing printing by discharging the ink, and an ink-jet printer including the same.

2. Description of the Related Art

An ink-jet printer is known, in which an ink is discharged from nozzles to recording paper to perform the printing. Such an ink-jet printer is generally provided with a detachable ink cartridge. When an ink-jet head is driven to perform the discharge operation in a state in which the ink is empty in the ink cartridge, then the printing is not only performed, but the air sometimes makes invasion into the ink-jet head. The ink-jet head, into which the air has made invasion, cannot be used in some cases. Therefore, it is necessary to detect the amount of the ink stored in the ink cartridge. A method for detecting the amount of the ink is conceived, in which the amount of the ink is detected by estimating and accumulating the amounts of the ink used every time when the printing is performed. However, any error tends to arise in such calculation. Therefore, it is necessary to stop the use of the ink cartridge with a sufficient margin. As a result, the ink is wasted. Accordingly, the following technique has been suggested (see, for example, Japanese Patent Application Laid-open No. 9-001819, FIG. 7). That is, a float, which has a specific gravity smaller than that of the ink, is arranged on the ink contained in the ink cartridge. The height of the float floating on the ink is detected from the outside to detect the amount of the ink contained in the ink cartridge. (more ink cartridges…)

printer toner cartridge – Canon Pixma MX7600

Filed under: Toner Cartridge — Cheap Ink Cartridges @ 6:54 pm

The multifunction printer, scanner, fax machine, and copier performed intuitively and yielded excellent quality prints. The MX7600 features superb photo print quality that you simply won’t get with a laser printer

The cheap MX7600 uses gunmetal grays, matte blacks, and glossy finishes enhancing its visual appeal. This printer demands a lot of desk space at 10.1 inches tall by 19.7 inches wide by 21 inches deep, and it’s certainly not meant for personal use. The printer weighs a hefty 36.6 pounds. It also consists of an automatic document feeder on the rear of the printer behind the flatbed scanner and it can hold 35 pages of plain or legal-sized paper. The front of the MX7600 is taken up by the comprehensive control panel. The Canon Pixma cheap MX7600 can print from a computer, through a direct PictBridge compatible camera, or from a memory card. Special photo prints include various layout prints, index prints, DPOF prints (prints according to the order format settings on the camera), and printing with the photo’s Exif information in the margins.

The cheap MX7600 printed pages faster than the MX700. The quality of prints has also improved as well. In contrast to its MX700 that has four ink tanks, the MX7600 has six tanks, five Lucia pigment inks and one cartridge of clear ink. Canon’s Pigment Reaction works by laying down a coat of the clear ink first and bonding it with the color pigments to create better quality graphics on plain paper. The MX7600 graphics are also bright and sharp, even on standard 20-pound sheets.

Protector for ink cartridge Description

The present application is based on Japanese Patent Application No. 2004-333922 filed on Nov. 18, 2004, the contents of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a protector that can prevent leakage of ink from an ink cartridge before the cartridge is attached to a recording device.

2. Discussion of Related Art

Japanese Patent Application Publication No. 2001-113723 or its corresponding U.S. Pat. No. 6,786,581B1 discloses an ink cartridge having an ink supply hole in which a valve member is provided. In a state of the ink cartridge before it is attached to an inkjet recording device, a compression spring elastically presses the valve member against a tubular packing member provided in the ink supply hole, so as to prevent leakage of ink from the ink supply hole. Meanwhile, when the ink cartridge is attached to the inkjet recording device, a tubular ink-supply needle pushes the valve member against the biasing force of the compression spring, so as to open the ink supply hole and thereby allow the ink to be supplied from the ink cartridge to the recording device.

However, the above-described valve member communicates with an outside space via the ink supply hole. Therefore, if the valve member is erroneously assembled in a tilted state when the ink cartridge is manufactured, or if the valve member is tilted by being interfered with by a foreign matter or a working person when the ink cartridge is manufactured or shipped, the ink may leak through the valve member tilted.
