Dear Sir or Madam,
Two years ago I purchased this all-in-one deskjet and for the first year it operated perfectly, both over usb and connected to my Airport wireless router. For the last year, however, I have been unable to get it to print correctly. Although it does print, the page misses multiple lines of printing. What I mean is that, for example, the bottom or top half of an entire line of words will not print, and the problem reoccurs multiple times on the page. It does not appear to occur regularly, and seems to be caused by the the black cartridge only.
Because the printer is no longer under warranty I have attempted to troubleshoot the problem myself. I have replaced both print cartridges with new HP branded media. I have run the clear cartridges utility and have cleaned the cartridge carriage contacts/ cartridge contacts using a Q-Tip with distilled water. I have also removed the black cartridge for two hours and turned it upside down as recommended. The problem does not occur in the copy or fax function - but does occur with wireless and usb-connected printing. The test page prints correctly.

First solution is to do a partial reset.
If this doesn't bring the solution!
perform a re-install of the printer.
if this doesn't help - you could do a re-install with an alterantive driver , of the 990C.
( this driver is standard available in windows software!)
add printer and use/pick the driver of the 990C.

I am having a problem with the printer. I have installed new cartridges and cleaned and aligned the printer. The pages print as they should when aligned. The problem is when I print documents from word or google docs. Some of the lines are missing or half printed. Can you help? I tried to click on the reset link but it brought me to an error page on your website.
