| First released in October 2005, the HP 4700 series of color laser printers are based on a 31-ppm, 600-dpi engine (3,600 dpi with RET). A short time later the 4730mfp machines were released with basically the same specs, but now as an MFP machine. In September 2006, the CP-4005 was released. All three series use virtually the same cartridges. The differences being the chips and the amount of toner (yield).
 The 4700 cartridges consist of the toner supply, drum and waste chamber. Like the CLJ-3600 these machines use an in-line or single-pass system. All four cartridges are stacked on top of one another and each color develops its own image, which is transferred to the paper by the transfer belt. This type of system is faster and allows for a higher quality print.
These cartridges have some interesting features. Instead of shipping locks that are removed and thrown away by the user, they have two small white plastic clips that are automatically disengaged when the cartridge is installed. These cartridges also have a self-removing seal system. The seal winds itself up on a small roller inside the cartridge. These items will be shown later in the article. |
