I changed my ink cartridges and can't get it to print. I did this; 1)Turned on computer 2)removed old cartridges 3)Removed cover tabs and installed new cartridges, Now my printer doesn't work I think I need to tell the computer I changed the cartridges. Before when I changed them the computer prompted me to say I changed them. This didn't happen this time. HELP !!.

Hi Karen:
If it worked before you installed this cartridge, there are 3 possibles that I would check.
1) The new cartridge is defective
2) The new cartridge is not installed correctly
3) The pull tab that covers the ink ports was not removed before the cartridge was installed.

Step one: Complete the alignment process If you have already installed new print cartridges, follow these steps to complete the alignment process.

1. After installing a new print cartridge, wait at least 20 seconds for the print cartridge alignment process to start.
2. Wait for the print cartridge alignment process to fully complete.
3. Make sure that the alignment page has printed on plain, white paper that has no other printing on it. If you need to create a new alignment page, load the tray with letter or A4 unused plain white paper and turn the product off and on again to create the page.

If an alignment page does not print when the product is turned on or off, the issue is resolved. If an alignment page continues to print when the product is turned on or off, you should replace the cartridges with new HP cartridges. Continue to Step two: Remove the print cartridges. Step two: Remove the print cartridges Follow the steps below to remove the cartridges. NOTE: When you remove and install the same print cartridge, the unit will not align the print cartridge as the unit remembers the alignment values for that print cartridge.

1. Press the Power button to turn the product on. The Power button is lit when the unit is on. Figure 1: Power button lit
2. Make sure that the paper tray is down, and letter or A4 unused plain white paper is loaded in the paper tray.
3. Lower the access door until it stops. Make sure that the print carriage moves to the right side. Figure 2: Lower the access door
4. Wait until the print carriage is idle and silent, and then using your thumb, lightly press down on a print cartridge to release it. Figure 3: Print carriage
   • If replacing the tri-color print cartridge, remove the print cartridge from the slot on the left.
   • If replacing the black or photo print cartridge, remove the print cartridge from the slot on the right.
   Figure 4: Proper position of the print cartridges 1 - Tri-color print cartridge 2 - Black or Photo print cartridge
5. Pull the print cartridge toward you and out of its slot.

Step three: Install the new print cartridge

1. Remove the new print cartridge from its packaging and, being careful to touch only the black plastic, gently remove the plastic tape by using the pink pull tab. Figure 5: Remove the tape 1 - Copper-colored contacts 2 - Plastic tape with pink pull tab (must be removed before installing) 3 - Ink nozzles under tape CAUTION: Do not touch the copper-colored contacts or ink nozzles. Touching these parts can result in clogs, ink failure, and bad electrical connections.
2. Slide the new print cartridge forward into the empty slot. Then gently push on the upper part of the print cartridge forward until it clicks into the socket.
   • If you are installing the tri-color print cartridge, slide it into the left slot.
   • If you are installing a black or photo print cartridge, slide it into the right slot.
   Figure 6: Print cartridge locations 1 - Print cartridge slot for the tri-color print cartridge 2 - Print cartridge slot for the black and photo print cartridges
3. Close the print cartridge access door. Figure 7: Closing the print cartridge door
4. If you installed a new print cartridge, the print cartridge alignment process starts after about 20 seconds.
5. The unit aligns the print cartridges. Recycle or discard the print cartridge alignment sheet.

If you have completed all the steps listed above and are still experiencing a problem, service the product. Cause The product aligns the print cartridges every time at cartridge installation or replacement to ensure the highest-quality prints. The alignment page continues to print when the product is turned on or off, or when a print job is started, for any of the reasons below.

• The automatic alignment process is not complete.
• The ink cartridges are not properly installed.
• One of the ink cartridges is defective.
• One of the ink cartridges is low or out of ink. Black and all three colors must be available.
• Protective tape on a new ink cartridge has not been removed.
• Contacts on the ink cartridge are not meeting the contacts in the carriage correctly.
• Cartridge is remanufactured or refilled. Refilled or remanufactured ink cartridges may have been damaged during the refilling process or have clogged ink nozzles.
• The product needs to be serviced.

Hello Sandi,

According to the product information you provided in your post, the following information should be able to provide you with the information needed to help you remove and replace the ink cartridges for your printer.

Ink Cartridge Removal Steps:

Keep your printer plugged in and on during this process.

1. Open the cartridge access door. The carriage moves to the center of the product. Wait until the carriage stops moving before proceeding.

2. Each ink cartridge will have plastic tabs located directly in front of them. Press in the tab on the front of one of the cartridges, and then pull it out and up to remove it from its slot. Once you have pressed the tab, you then pull up and out on the cartridge and it should come out easily.

Illustration of process:


3. Repeat this step to remove all cartridges from their slots. Remember that each ink cartridge will have to be removed individually if your printer has more than one cartridge.

Replacing the cartridge with the new one:

1. Remove the ink cartridge from the packaging and then remove the protective covering.

2. Hold the ink cartridge in the same position as you removed the old ones. Push in and then down on the new ink cartridge which should lock them into position with the tabs automatically and you will you will usually hear a clicking noise when this is done.

3. Close the cartridge access door. The printer will automatically reposition the cartridge print head assembly for you.

This should complete the process and you should now be able to print. Some printer will ask or recommend that you print a test page so that it can calibrate the desired ink usage, position, darkness, etc. If this appears on your screen just follow the directions as prompted to complete the test page.

I hope this provides you with a bit more clarity for removing and reinstalling your printer ink cartridges. If you have any further questions or need additional assistance, please feel free to ask. Have a good day.

Try cleaning the heads. This should get the printer cartidges unclogged so the ink comes out. Also are you using epson cartridges or generic. How old are they. If new or quality generic. Its probably the head needs to be cleaned go through that process 2 or 3 times as its much cheaper than new cartridges.
