Individual Ink Cartridges: Customers will enjoy affordable printing with low-cost, individual ink cartridges, letting them replace each ink cartridge separately when its needed. Original HP high capacity ink cartridges ensure fewer cartridge changes and a better value for frequent printing. Based on HP testing, HP 920XL Black Ink cartridge yields approximately 1200 pages; HP 920 Black Ink Cartridge yields approximately 420 pages and HP 920XL Cyan, Magenta and Yellow cartridges yield approximately 700 pages based on HP testing. Select regions will off both standard and high-capacity color cartridges. For more information about HP ink cartridges and page yields, please visit: www.hp.com/go/learnaboutsupplies Dual-drop volume printhead: This technology allows customers to print high quality photos and graphics focused marketing materials comparable to systems requiring more ink colors, eliminates the need for lighter, photo dye-load inks, reducing image grain and increasing the available color gamut for photos and graphics on specialty coated papers. In dual-drop-volume modes, the printer can eject color droplets as small as 1.3 pl and as large as 5.5 pl. About 3.8 billion of these 1.3 picoliter droplets would fit in a teaspoon. The printer can fire any combination of these small or large ink droplets on a given print positionsmall and large droplets together, just small drops or just large. The size and combinations of ink droplets are determined by the printer in order to provide the optimum print quality and speed. Dual-drop-volume printing is used when printing photos and color graphics in Normal, Best and Maximum-dpi print modes on select HP photo and brochure papers2.

Half-toning: The HP Officejet 6500/6000 All-in-One uses high-quality, high-resolution half-toning to deliver enhanced gradient tones for smooth, uniform color output. Halftoning is the process used by inkjet printing systems to lay down different combinations of ink droplets, distributing small ink drops evenly, with minimal overlap between dots to create the range of colors seen on the printed page. Optimal dot-placement patterns are achieved using improved half-toning algorithms, updated for optimal performance with HP dual-drop-volume technology. HP advanced half-toning is utilized in all print modes.
Designed for quick print speeds: The new printing system includes a resistor innovation that enables the 36kHz high-frequency firing speed. This resistor innovation also enables a high nozzle count720 for black and 672 for each colorfor a total of 2,736 nozzles. These tightly compacted nozzles (1,200 per inch) are capable of firing at 98 million drops per second, and delivering efficient speeds for plain papers such as those with the ColorLok logo and coated paper such as HP Brochure Paper.

Long-life integrated print head: The HP Officejet 6500/6000 printer uses a longlasting, dual-drop-volume print head in a new, integrated design. The print head is built on silicon wafers using photolithography to maintain accuracy and alignment throughout the entire system. Closely integrated components enable precise, accurate drop placement for fast, high-quality printing and consistent, reliable results over the life of the product. Using Original HP ink cartridges and other system innovations help ensure reliable operation by preventing particles and air bubbles from entering the print head. Smart Printing Technology: Allows Original HP ink supplies to communicate directly with the printer, and ensures the cartridges receive the exact amount of energy required to fire the resistors. These precise adjustments in energy levels help prolong printhead life and maintain great print quality. HP Smart Printing technology makes it easy for customers to monitor ink supplies with estimated ink-level status information and low-ink alerts. Using their printer software, customers can view graphical representations of estimated ink levels in installed cartridges, displayed in 10-percent increments. Low-ink alerts enable customers to plan
ahead and have replacement cartridges on hand.
Q: What are the advantages of pigment black ink and color dye inks? A: Versatile HP 920 Officejet inks are optimized for printing on plain papers, including ColorLok papers, and coated papers such as HP Brochure Paper. HP 920 Officejet black ink is pigment-based and provides crisp, bold business-quality black text that resists water and smudging on plain paper, and will maintain black text quality for decades without fading in archived documents3. HP 920 Officejet color dye inks provide rich color for vivid color photos, charts and text. The neutral, non-acidic nature of the HP 920 Officejet inks helps prevent corrosion of the print heads, which enhances reliability and significantly extends the life of the print head. Q: Why are papers with the ColorLok logo recommended for use with HP Officejet inks? A: HP 920 Officejet black ink is pigment-based and is compatible with virtually all plain and specialty papers designed for inkjet printing. ColorLok papers must pass a series of performance standards and include enhancement technologies that react with HP 920 Officejet black pigment ink to keep the ink colorants on the surface of the paper reducing the chance of black-to-color bleed and strike through resulting in crisp, bold black text. As seen in the images below, the pigment black colorants remain on the surface of ColorLok papers ensuring uniform coverage and bold blacks.
