  • I have a LaserJet 2420dn which has stopped working due to a service error - code 49.4C02 service error. How do I clear this error? Does this mean a repair or service is required? Unfortunately, I don't have the user manual. Many thanks.

HP LaserJet 2420dn Printer Review

Expert review of the HP LaserJet 2420dn printer

Our Verdict:

A wiser choice for workgroups in need of a shareware, the HP LaserJet 2420dn offers built-in networking in addition to duplexing and basic laser printing features. This monochrome printer is best for home and small office applications, although some may find it quite expensive for a single-function monochrome printer. The HP LaserJet 2420dn printer may cost higher, upfront, but its running costs are kept low with economical toner cartridges that offer high page yields. Designed for black and white printing, users will have to purchase a separate colour printer to complement the HP 2420dn printer.


Measuring just about 10.2x16.7x15.7 inches, the HP LaserJet 2420dn printer is compact and fairly lightweight at only 33.5 pounds. While the HP LaserJet 2420dn monochrome printer still offers the standard paper capacity, an additional paper tray can be purchased for those with heavier printing needs. The main tray can hold up to 250 sheets, while the multipurpose tray for specialty paper holds another 100 sheets.


The HP LaserJet 2420dn offers an even faster print rate average; at 30 ppm, it is one of the fastest in its range. The LaserJet 2420dn is even faster than more expensive printers, although graphics quality sometimes suffers. Built-in networking is beneficial for workgroups, while those who want to save on consumables can always use the auto duplex function. The HP LaserJet 2420dn is also capable of printing up to 75,000 pages in a month as well as using cheaper compatible HP 2420dn printer cartridges which are manufactured by third-parties.


The HP LaserJet 2420dn does not offer impressive graphics outputs, and users will have to supplement its lack of colour printing capabilities by purchasing a dedicated colour printer.
