The Canon BJC-6000 is the smart choice for all your printing needs, whether for a busy workplace or a home office. It establishes a new benchmark in affordable, professional-quality printing by adding intelligent functions that help you work smarter. From fast, high resolution black and color printing to amazing photo output using optional Canon Photo Inks. Plus, an intelligent ink system featuring individual ink tanks that eliminates ink waste and saves you money.The Canon Think Tank System is an intelligent ink-management system unique to the BJC-6000 Color Bubble Jet printer. It features individual ink tanks for each color ink, so you replace only the color you need as it runs out. Wasting ink by having to replace all the colors in a cartridge just because one color is spent is a thing of the past. The BJC-6000 uses individual ink tanks for each color. When one runs out, simply replace that color - not the entire cartridge. No more ink waste - just big money savings. Ever run out of ink right in the middle of an important print job? Never again. The BJC-6000's built-in optical low-ink sensor actually warns you with an on-screen message when a specific ink tank is low. So you can replace the empty ink tank just at the right time.
