HP’s 2400 series line of printers contains some of the most model variations on the market today. From the base HP LaserJet 2420 and 2430 models, to duplex and network ready versions, all the way up to the fully loaded HP LaserJet 2420dtn model with extra paper storage, expanded memory, a duplexor, and other features. With a single printer available in a total of seven different model variations, the LaserJet 2400 series is the perfect monochrome laser printer for the picky buyer.
The first in the 2400 series is the HP LaserJet 2420, a black and white personal laser printer with an appealing set of specifications for the home user or small office. It operates at 30 pages per minute in full print quality, making it one of the fastest models of its size on the market.
The HP LaserJet 2420 also comes with 32 MBs of built in RAM which is then upgradeable up to 288 MBs. The 2420d and 2420dn models come standard with 48 MBs and 64 MBs, and are expandable to 304 MBs and 320 MBs respectively. While the LaserJet 2420 is not complete with a built in duplexor, the d and dn versions are.
Built in duplexing allows for automatic double sided printing and, while print speeds will be reduced by a significant margin when operational, it allows for paper costs can be cut virtually in half. The HP LaserJet 2420dn model includes a network card as well for office wide Ethernet usage.
A first page out time of less than ten seconds means that even single page print jobs will come out quickly, and the incredibly fast 400 MHz MIPS 20CK processor should help to keep slowdown to a minimum for large projects, even when the network is in use.
On top of two 100 pin DDR DIMM slots (one open) and MEt memory enhancement technology, two compact flash memory slots are also implemented into the HP LaserJet 2420′s hardware, and, as the model was designed as an office printer, it boasts a very high 75,000 page per month maximum duty cycle. On top of this, HP backs its product with a one year return to HP authorized service center warranty.
Despite the HP LaserJet 2420, and its siblings, being incredibly powerful, its dimensions are admirably small, with a footprint of 16.7 in. by 15.7 in. 10.2 in. (W x D x H) and a weight of 36 pounds. If an optional additional paper tray is incorporated into the hardware, both height and weight will increase, but within reasonable levels.
A 100 sheet multipurpose tray and a 250 sheet standard legal sized paper tray compose the HP LaserJet 2420‘s standard paper handling abilities, and additional 250 sheet and 500 sheet paper trays are available for expansion, though the unit has a maximum paper storage capacity of 850 sheets. With so many customization options available and such eye catching hardware, HP’s 2400 series is hard for those in the market for a powerful, compact monochrome laser printer not to notice.
