HP Deskjet 840C Printer



This inkjet printer is designed for the home or small office. It attaches to a computer via the classic parallel cable or to a USB port. You should connect the USB cable from the printer to the computer before you apply power to the printer. It can be used with Windows 3.1, 95 via parallel port, or 98, Me, and XP via USB. The black inkjet cartridge is the #15, the tricolor inkjet cartridge is the #17. The #17 tricolor cartridges is often harder to find. This printer works well for the average user. When installing the printer you may have to create a USB Virtual printer port if another printer was previously defined (not for printers connected to a parallel port).



HP seems to have a policy of "planned obsolescence" in manufacturing new printers that use new inkjet cartridges. Over time it becomes harder to quickly purchase replacement cartridges. If you bought a used printer you can refer to another HP printer manual for general advice. HP advises against refilling a cartridge but you may find doing this useful.



The HP840C User's Guide has a Table of Contents that covers the topics in its 74 pages. Be sure to read the warnings in the manual about proper care of inkjet cartridges. Leaving them unused for many months may shorten their useful life. New cartridges have a plastic tape over the nozzles to prevent oxidation of the ink. One user had a problem with the separate power supply. It is probably not good practice to keep the printer powered on when not in use. Like other HP printers the paper path takes a U-turn in printing so the printer uses less desk space. Be sure the bottom tray is pushed against the printer body, a loose fit can cause printing problems. [I bought this at a local yard sale w/o power supply, truly a bargain.]
