HP Deskjet 990Cxi prints `in white!'
Hi,
I've got an old Hp Deskjet 990Cxi which suddenly decided to print nothing. When I send a document to the printer, it behaves as before (paper is taken, cartridges move, etc.), but the resulting page is still as white as it was before printing. The problem does not come from the computer, because I tried several things. Among them, * Printing test: holding the resume button for more than 4 secs. makes it print, but the page is still white; * Technical test: having the power button hold, and then pressing 4 times the resume button. A page seems to be printed (same behaviour), but, just as before, nothing is printed, despite cartridges' movements, etc. Any idea? I need to make it work. Thanks. |

MULTI-POSTING is a really STUPID idea (was: Deskjet...)

That way, everyone who reads the question can see ALL the responses. This is called CROSS-posting. The way you have done this is selfish and inefficient. |

How can you tell if I have answer your question if you are only looking at THIS group, while you have posted it to MULTIPLE groups? Please answer to it if you have any solution. Go look at ALL the places you have splattered your question, STUPID. |

Have you pushed the print head against a paper towel and had ink actually come out of the print heasd??? |

Have you removed the cover on the print heads? *Have you pushed the
print head against a paper towel and had ink actually come out of the print heasd??? Yes. @ Michael: yes, but the other group is so damn infected with spam that I don't think it worths it. |

Yes. @ Michael: yes, but the other group is so damn infected with spam that I don't think it worths it. Damaged flex circuit to the print head carrage? How did the problem appear? Was it printing fine one page and nothing the next? Did it print fine then you replaced the cart[s] and it no longer printed? We need a bit more history to offer useful suggestions. Neil S. |

HP cartridges eject the ink by applying a pulse of electricity to a heating element in the cartridge. There would be one element for each color in a multi-color cartridge. Since you have tried different new cartridges, and a self-test you have eliminated the cartridges and the computer. That leaves the cause as something internal to the printer. This would be a failure of the printer electronics, a flaw in the cable connecting the print head to the electronics board, or possibly contamination of the contact pad on the printer carriage.

PlainBill Most likely the the power supply for the pulse current source. Well, I moved the printer and washed my cartridges with alcohol. They were quite old (but new too: just never used for many), and using heat and alcohol, they worked perfectly. Thanks. (I had not used the printer for a while.) |
