HP 820cxi
Just repaired one of these.
Before connecting it to the computer I tried the self test i.e. 1. Turn the printer on. 2. Press and hold the POWER button. 3. Press the RESUME button four times. 4. Release the POWER button. All I got was a couple of short vertical lines on the paper. It works fine connected to an XP box. Then I found this http://h10025.www1.hp.com/ewfrf/wc/document? lc=en&cc=us&docname=bpd07098&dlc=en&lang=en#N1368 About a third of a way down the page it says "NOTE: There are no internal clean or diagnostic tests for the HP Deskjet 820cse and 820cxi printers." Does this mean there is no self test in the 820cxi and that's why all I got was the short lines? |

Tony Tony, what I meant to say is does that mean there is no way to print a test page using the buttons on the 820cxi? I think the answer is no, because for other printers listed on that page they talk about self/diagnostic tests, and sample pages under separate headings. Nick |

It does virtually nothing on it's own and really only understands basic graphics printing. Everything, including text, must be sent from a driver on the computer. That explains it. Many thanks Andrew. |

Does this mean there is no self test in the 820cxi and that's why all I got was the short lines? This is not quite true, the short lines actually *are* the rudimentary self test. With good working cartridges you would have lines of black, cyan, magenta and yellow. If there are missing colors (typically yellow and cyan missing first) it would indicate an issue with the cartridge. If all three colors from the #41 cartridge are missing it could be either an issue with the cartridges or the printer electronics. In this case blot the color cartridge with a damp tissue. A good cartridge would show a strong strip of cyan, magenta and yellow, similar with black for the #45 cartridge. Regards, Bob Headrick, MS MVP Printing/Imaging |
