My Dell A940 has been sitting for a while. The cartridges are nearly full, but when I do a print test page, there is very little ink on the paper. I suspect that the printhead may be plugged. Can it be cleaned? How? I did remove the cartridges and with a cotton swab and alcohol, cleaned them.

Write to Lexmark - you won't get any joy, but their reply might be interesting. I suspect that Lexmark builds a chip into their cartridges preventing it being refilled. When replying to me they did not admit this, but did not deny it, simply stating that their cartridges were designed for single use only. When I said that, apart from the cost, I wanted to minimise my impact on the environment by refilling cartridges, they pointed out their proud association with Planet Ark. I suspect that Planet Ark is happy to be an apologist for corporate vandals, and I seriously question their 'green' credentials. Order your next cartridges from Europe where the printer companies are not allowed to chip their products.

SOURCE: HP 7310xi: "Remove and Check Printer Cartridge on the right"

This is the exact same issue that I have. After looking at the carriage with a flashlight I determined the wire on the right side of the carriage has come loose and small pieces of plastic that holds it in place has broken off. When that happened the end of the wire pearced the ribbon behind it.

The carriage and ribbon have to be replaced.

My HP Deskjet 6940 is not printing. The color (left) low ink light is dark and the black (right) low ink light is flashing. I replaced the black ink cartridge with a new one but the low ink light continues to flash. No tears/rips in the circuit strip and all the copper leads appear to be connected

Firstoff,

Good on you for trying all of the above, if your printer has a print head problem you can find out easily by going into your printer toolbox.

Double click the HP Digital Imaging Monitor on the taskbar to the left of the clock.

when it opens click Settings=>Printer Settings=>Printer Toolbox

Ink levels will be displayed there, If the Black ink is showing empty the sensor for that cartridge must be dead(three strikes), Call HP and request a warranty replacement, or, take it back to staples as they generally handle 1 year in the store.

If the black in is showing here then the sensor is good, click the Information tab at the top of this window, then click Printhead Health. If the Black/Yellow is yellow or red Call HP and they should issue you a new one under warranty. If it is green this is not the problem.

Continue by closing that window, then Clicking Settings=>Printer Settings=>Printer Settings

Click on the Colour tab then switch the printer to greyscale and try printing again.

If this doesn't clear the head it may simply be caked or have an airlock.

To ensure it isn't caked simply soak the head in rubbing alcohol 2-3mm deep on the head for an hour or so, then replace it and try again.


Unfortunately if none of these work you may be stuck dealing with HP for a warranty exchange, www.hp.com click support then click chat with an online support technician.

or talk to your staples rep about having it replaced through the instore warranty if you have instore coverage.


Hope this helps FixYa,

Chris
