  • 8. HP3500/3700 Technical Instructions 8 HP 3500/3700 In January of 2004, HP released two color laser printers into the North American market. The HP Color LaserJet 3500 and 3700 are based on a new Canon engine similar to that of the HP 4600. The single pass engine design enables the new printers to deliver 12ppm and 16ppm while printing either monochrome or color. While both machines use the same black cartridge, the color cartridges are different. The black cartridge, Q2670A, yields 6,000 pages at 5 % coverage. The color cartridges for the HP3500, Q2671A (cyan), Q2672A (yellow), Q2673A (magenta), yield 4,000 pages at 5 % coverage. The HP3700 color car- tridges, Q2681A (cyan), Q2682A (yellow), Q2683A (magenta), yield 6,000 pages at 5 % coverage. All the internal components are the same for all the cartridges the only difference is the chip and the cartridge fill weights.
