Don't think that cleaning will clear up a colour shift problem. Upgrade the firmware to 20040930, if it isn't already.

I put new print cartridges in my 960c printer. They are hp 78 for color and 45 for black and white. my orange ink light will not stop blinking. It is not printing

I have an HP DeskJet 1220C that has been working fine for two years now. All of a sudden it can only print in pink and black. It is driving me crazy. I have tried the following without any success:

1. Replaced the cartridges twice
2. Aligned and cleaned the cartridge from the
3. Soaked the cartridge head in hot water,
and made sure that all three colors will bleed
out of the head
4. Cleaned the cartridge contacts with an eraser

with a brush

Is there a cure, or is it time for a new printer?

How to remove the cause of a black line a HP Laser Jet printer model 4250 has produced down the center of everything printed for a long time? Thorough cleaning has had a very little effect.Last week I...

In cases of print quality issues you should always start with the imaging drum. In this case the toner cartridge. Make sure it is not a re-manufactured or refurbished toner cartridge. A lot of times when someone refurbishes the cartridge they don't replace the imaging drum (the blueish green drum under the shutter). Check for toner stuck or burned on the drum. If there is you need to replace the toner cartridge

If there is no toner stuck or burned on the imaging drum then you more than likely you will need to check or replace the Fuser in the back of the machine. The back door of the machine comes out easily enough and the fuser clips into place. **Be careful it doing to be hot.** Remove the fuser and check the rollers inside for burned toner or damage. If so replace the fuser .

You can purchase a Fuser Kit from HP or find a refurbished fuser from Depot America or for a lot less.

Do the reset chips really work on the cartridges of HP 2500N laserjet printer

Yes, reset chips really work on laser printer cartridges, if you have a know good source for the chips and if you know what your doing, you can't put a new chip on an old cartridge, the chip is what registeres how may prints you will get out of the cartridge if you put a new chip on an old or 1/2 empty cartridge of course it will say it's full but then try and print.It will register as a full cartridge but it can only print with the amount of toner that is actually left in the cartridge, be careful there are alot of remanufactures out there that don't put new chips on or that do but don't fill the cartridge full, or replace all the wipers and drums, they just dump some toner in and say here you go, Only buy your remanufactured cartridges from a reputable company, do your research on them first or you'll be sorry

Printing not complete

you may check your ink cartridge
1) the cartridge some color almost empty, need to change a new one or refill the match color ink. test it and go next if not fixed
2) long time less using cause some color ink chanel(holes) dryer, you may take out the color ink cartridge and put it's surface of bottom (just touch ) in the clean water 1 Hr, then set back and test it. still not fixed, you also need to do same thing if your print head is separated from your ink cartridge

Despite installing new cartridges,cleaning and priming, my HP Deskjet 710C prints pink only. Using Windows XP test page shows no blue, or yellow.

do you installing both cartridges (black and colour)?
if you do so, my advice is to reinstall the driver for your printer.

if you install ONLY the black cartridge, and the color cartridge remain the old one, (which in my opinion is the present case), your problem is from the color cartridge.
The color cartridge have 3 colors and this are: cyan (some kind of blue), yellow and magenta (similar with a pink color, but more intense). The problem is simple: in your color cartridge has left only the magenta color, cyan and yellow tanks are empty.

have 2 options:
1. buy a new color cartridge
2. refill the color cartridge.

Everything printing in PINK

Assuming you have successfully eliminated cartridge/print head problems, the only other thing to try is to delete the printer software and reinstall [Start/Printers and faxes -right click on the printer icon click delete- install new printer -Have the software disk and handy or select from list- select maker, select model,] I suspect the problem is still print head/cartridge however
