HP CLJ 3000/3600/3800
In October of 2005, Hewlett-Packard (HP) released three color laser
printers into the North American market. The HP Color LaserJet 3000,
3600, and 3800 are based on a new Canon engine similar to the HP
Color LaserJet 2600. The single pass engine design enables the new
printers to print from 15ppm to 30ppm with only one model (HP CLJ
3000) slowing down to print color.

The HP Color LaserJet 3600 and 3800 share the same black car-
tridge, the rest of the cartridges are unique to each model. The HP CLJ
3600/3800 black cartridge, Q6470A, has a 6K page yield at 5% cov-
erage. The color cartridges for the HP CLJ 3800, Q7581A (cyan),
Q7582A (yellow), Q7583 (magenta), have a 6K page yield at 5% cov-
erage. The color cartridges for the HP CLJ 3600, Q6471A (cyan),
Q6472A (yellow), Q6473 (magenta), have a 4K page yield at 5% cov-
erage. The HP CLJ 3000 black cartridge, Q7560A, has a 6.5K page
yield at 5% coverage. The color cartridges for the HP CLJ 3000,
Q7561A (cyan), Q7562A (yellow), Q7563 (magenta), have a 3.5K page
yield at 5% coverage.
