Routine maintenance and keeping full ink tanks will prevent this problem, however if you have the problem you can resolve it by doing the following:
1. Clean your print head using denatured alcohol solvent which can be purchased from most hardware stores. If unavailable, use 91% Alcohol (isopropyl alcohol (first aid antiseptic) which is available for less than a dollar at most Walmart pharmacy departments.

*Warning: You may want to use a pair of latex exam gloves as this is a messy process and can stain your fingers.
Time necessary 45-50 minutes
Supplies needed:
Isopropyl Alcohol or denatured alcohol
paper towels
latex gloves
sink, bowls and or basin
can of compressed air
very small screw driver
tablespoon or baby bulb type syringe
warm water

PROCEDURE:
1. Lift print head from printer. It pulls out easily because it is held in with the same down lever that holds the cartridge in place.
2. Put two layers of paper towels in the bottom of a dish to protect sensitive sprayer heads.
3.Put enough solvent in dish to cover the screens on which the cartridges sit when in use.
4. Take the two small screws out that hold the white ceramic piece
5. Gently, pry the ceramic piece back and away , to reveal the underside (No need to pull away the glued points on the sides.)
6. Gently, move head up and down to slosh solvent around it the best as you can. Use a table spoon or syringe to pour solvent over all orifices in the print head, turning it upside down and then back a few times.
7. Use canned air with a plastic straw to blow into and through all orifices, alternately sloshing/swishing and pouring solvent over head (be careful not to touch any of the holes, screens, or sprayer heads with anything)
8. Empty dirty solvent from bowl and replace with paper towels and clean solvent. Soak for approx 10 minutes. Rinse again with clean solvent poured directly on all parts, letting solvent overrun and fall into dish or basin.
9. Gently shake the solvent off the head, take it outside and spray with compressed air into all orifices to clear out and help evaporate any remaining solvent. Let sit on a clean paper towel for approx 20 minutes. (There may be a little ink bleeding out of the head, but once it dries completely it does not present any problems.
10. Reinstall head, cartridges and it will print like a new printer.

SUGGESTION: For many years of problem free printing, keep a double set of ink cartridges, one set full at all times. Whenever a cartridge runs out of ink, replace it IMMEDIATELY, with a new one or a refilled one. This gives the print head no chance to dry out and create clogged heads. Routine maintenance of cleaning the heads every 24 months does wonders for keeping your printer in new condition.

Hope this helps. .

Ink cartridge installed but cartridge light continues to blink


Have you only replaced the magenta cartridge, or have you also tried the print head. A bad print head can cause the ink to read as empty or clogged.

Will not print


“All lights blinking and printer not responding” is indicative of serious ink cartridge issue. Usually when this happens the printer fails to goes through the motions of the printing process, kind of stands still with indicator lights just blinking away. This could be as a result of either of these scenarios.
i. Ink cartridge has developed incompatibility or is incompatible
The Solution is to try an older/another cartridge (doesn’t matter if ink is finished. You must replace cartridge one at a time). If lights stop blinking it confirms that your cartridge has become incompatible or developed incompatibility. Also if your printer is the type that can work with only one cartridge, remove one after the other (closing back the lid/cover) to determine which in the set (black or color) has become incompatible. At the instance the incompatible one is removed and you close the lid, the blinking will stop (for printers that can print with one ink cartridge only). Just replace the incompatible one and start printing again. In most cases the issue is always with one cartridge. But if both are affected, you have to replace both. Because of this type of problem, always keep used cartridges somewhere safe; they come in handy for this type of troubleshooting.
ii. The Cartridge electronic panel is dirty
The electronic panel on the cartridge that makes contact with the cartridge carrier inside the printer is dirty and needs cleaning. This electronic panel is front part of the cartridge with copper “dots”.
The Solution is to try to clean this panel with a piece of folded tissue paper soaked in a bit of methylated spirit. Also try to clean the area in the cartridge carrier/holder that makes contact with the cartridge’s electronic panel (Usually this is more difficult). If you cannot reach it with your fingers, use a stick or something with tissue wrapped around it. Allow to dry well and return the cartridges, close the cover. The blinking should stop if the electronic panel is the issue. Once the blinking stops the printer will print.

Replace ink cart and amber light still blinks


Usually if the Amber light is blinking with a new cartridge, that cartridge has bad electronics.

Try replacing the cartridge with another or the old one, if the light goes out it was just a bad cartridge.

Blinking teardrop light blinking


Blinking drop light on HP6122 signifies an ink cartridge is out of ink. There are two cartridges -- color (larger of two) and black (smaller of two). Blinking drop light only indicates either, but not which. HP6122 service software and print driver are available from HP website http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=83027&lc=en&cc=us&dlc=en&lang=en&cc=us. HP6122 service software has a printer maintenance utility which includes ink cartridge monitor. Use the maitenance service utility to determine which (or both) cartridge is out of ink. With cartridge replacement, printer should automatically print test page, then reset and be ready for printing from your computer. To clear printed documents from print que, open the HP6122 print que via control panel > printers > double-click on HP6122 driver to show que > select document tab > select cancel.

Says replace ink cartridge


I have replaced my ink cartridges numerous times and they are still full. It keeps telling me the ink cartridge needs replacing. It won't print and the red light keeps blinking. I have disconnected the usb and the power. I have only had this printer for about a year. It won't scan or print. Its a Kodak Easyshare 5300. The HomeCenter AiO is disconnected so how do I contact anyone from Kodak?

Printer does not print at all


Did u remove the cellotape that covers the printhead of the new cartridge?
Other solution:
if using XP: use the HP toolbox to prepare the new catridges for firsttime printing.
If using Vista, go to start-controlpanel-printers and rightclick on hp940C icon, choose properties, select services and do a cleaning and prepare job.

HP 932 RED LIGHT STAYS ON


The light you describe is the ink light.
When that light is blinking, try this.

Turn on the printer. Open the front cover and look at the carrier for the ink cartridges. There is a white arrow right above the latch for the color cartridge.
Once the carrier stops moving, the white arrow should be pointing to a symbol which represents the problem (the reason the light is blinking.) Examples are low ink black, low ink color, sick black ( replace ) , sick color ( replace ).

IF you have just replaced your black cartridge, you might need to replace your color cartridge too.
This printer will not work without both ink cartridges installed and full.
You cant print with a full black and an empty color cartridge unfortunately, even if you only want to print black.

Hope this helps!
