Hp ink cartridge replacement

Thank you for your assistance in this matter.
Everytime I replace the ink cartridge when the ink requires replacement the ink does not seem to inject.  Sometimes I restart the system, that does not help.  Sometimes I turn off my computer et al for a day, that does not help. 

I put new cartridge in 2 days ago, still does not work.  As the cartridges do not have instructions for this and the person who owns the hpdeskjet 940c printer is unable to locate the manual to alleviate this problem.  HELP!!!

I bought a black ink for my hp photosmart c5 180 and the when i turn on the printer it says the ink has expired. Can i still use it or will i damage my printer. Thanks regards Anita

according to HP
Each ink cartridge has an expiration date. The purpose of expiration is to protect the printing system and to ensure ink quality. When you receive an ink cartridge(s) are expired message, remove and replace the expired ink cartridge, and then close the message. You can also continue printing without replacing the ink cartridge, by following the instructions on the HP All-in-One or the ink cartridge expiration message on your computer screen. HP recommends replacing the expired ink cartridges. HP cannot guarantee the quality or reliability of expired ink cartridges. Device service or repairs required as a result of using expired ink will not be covered under warranty.

Why stil show empty after installation of refilled ink cartridge

Hi there,

As you were using a refilled ink cartridge, it needs to be reset. When you refill your cartridge, it will read as low or empty when you try to print with the cartridge.

There was a embedded serial number in the contact strip located on the back of the cartridge and your printer remembers that serial number and gives the message of low or out of ink. The internal memory is located in the printers firmware and is not in the software. It will remember the previous two cartridges ink level.

On this matter I need the exact model of your HP printer so I can assist you more further on this.

Let me know from you again here soon. Just leave a message and I will attend you ASAP.

Thank you for using fixya.

Hp Besiness inkjet 1100 fault codes cayan maginta ink and paper lights come on dead

HP Business Inkjet 1100 stops everytime after the first line stars to print. The power is one, the ink drop light is lit, the "yellow" indicator light also on, and the paper light all on. None of them blinking. We replaced the yellow cartridge with a brand new HP 11 yellow cartridge. Turned the printer off and on to reset. Printer comes on everything looks good till you try to print anything, even a on line word doc? Then it happens again, so we replaced the yellow again...same thing. We ever cleaned print heads, Any assistance would be welcomed?

Everytime I try to print , all i get is a a blank page

If you are using it on a MAC there are known issues.

If however it is a pc then maybe you should check your ink levels using the software that you installed with the printer.

Have you recently replaced the ink cartridges and if so did you use original HP cartridges ?

If you didn't use original cartridges then there is quite a good chance that they may be faulty and should be returned to where you purchased them for replacement.

If you did use original cartridges did you remove the tape on it before installing ?
Check by doing the cartridge replacement steps and take out any cartridge you may have replaced recently and check that the pull off tape tags are removed.

HP C7280 Printer not priting wirelessly.

Solution Replace the indicated ink cartridge(s), or press OK on the control panel to continue. HP recommends the use of genuine HP ink cartridges. Genuine HP ink cartridges are designed and tested with HP printers to help produce great results, time after time.
NOTE: HP cannot guarantee the quality or reliability of non-HP ink. Printer service or repairs required as a result of printer failure or damage due to the use of non-HP ink will not be covered under warranty. Follow these steps to replace the depleted HP ink cartridge(s). Step one: Replace the indicated cartridge(s)
  1. Make sure the HP All-in-One is turned on.
    NOTE: The Attention light blinks when the product is turned on.
  2. Open the access door by lifting from the front center of the HP All-in-One, until the door locks into place. Figure 1: Opening the access door c01079714.jpg
  3. Squeeze the bottom of the latch below the ink cartridge to replace, and then lift the latch.
    • To replace the black ink cartridge, lift the latch on the far left.
    • To replace one of the five color ink cartridges, such as yellow, light cyan (blue), cyan, light magenta (pink), or magenta, lift the appropriate latch in the center area.
    Figure 2: Lifting the latch c01079715.jpg 1 - Ink cartridge latch for the black ink cartridge 2 - Ink cartridge latches for the color ink cartridges
  4. Pull the ink cartridge towards you out of its slot to remove it. Figure 3: Removing the ink cartridge c01079716.jpg
  5. Remove the new ink cartridge from its packaging.
  6. Holding the new ink cartridge by the handle, push the ink cartridge into the empty slot. Match the color and pattern of the ink cartridge to the color and pattern on the print carriage. Figure 4: Inserting the new cartridge c01079717.jpg
  7. Close the latch, and make sure it is secure. c01079718.jpg
  8. Close the access door. Figure 5: Closing the access door c01079719.jpg
Step two: Align the new ink cartridge(s)
  1. Make sure paper is loaded in the input tray, and then press the OK button. The HP All-in-One prints the alignment page, aligns the printhead, and initializes the ink cartridges. This takes approximately 5 minutes. CAUTION: Do not disconnect or turn off the HP All-in-One during this time. You may hear the HP All-in-One making noises.
  2. Check the display for status, and then press the OK button. Recycle or discard the alignment page.
Cause The original HP ink in the indicated ink cartridge(s) has been depleted.

HP Photosmart C3100 series

I just got off the HP help line.  After changing my black ink cartridge a test page was printing each time I turned the machine on.  This is very costly, in both time and ink as the cartridges themselves for this machine hold very little ink.  I tried to learn from HP tech how to turn off the test-print while keeping my color cartridge empty.  It turns out that you cant do it.  HP requires you to keep buying and using cartridges whether you need them or not.If you buy the color ink it will use it up in its testings.  And if you dont buy the color cartridge it will use up your black ink by printing the test each time you turn on the printer.  The printer was inexpensive sure, but I'm paying for it in wasted ink.
