Lexmark x2500 I have purchased the #28 Black ink cartridge and the #29 Color ink cartridge for my Lexmark x2500 which is listed for the type I needed to buy at both the place I bought it and the Lexmark site. I am having trouble with the printer not being able to communicate with the ink cartridges or it says they are invalid. They have been installed correctly but the same thing every time. Hope you have a solution thank you!

Try refilling them yourself, just do not let them run out and you have to push the reset button once to restart after it says they are empty

Here is an instruction set I found at http://www.ehow.com/how_4488808_replace-ink-cartridges-lexmark-x2500.html

Step 1 Press the "Power" button to turn on your Lexmark X2500 3-in-1 printer.

Step 2 Open the top portion of the printer to reveal the ink cartridges.

Step 3 Lift the gray plastic cover on the left. Remove the empty black #28 ink cartridge. Next, lift the purple plastic cover on the right and remove the empty color #29 ink cartridge.

Step 4 Remove the new black #28 ink refill cartridge from its packaging. Tear the protective strip of paper from the cartridge's sensor. Now, remove the new color #29 ink refill cartridge from its packaging and tear the protective strip of paper from the cartridge's sensor.

Step 5 Turn the cartridges so that you can read the label. This is the way the cartridges should face when being put into the printer.

Step 6 Slide the black #28 cartridge into the slot on the left side and push it down. Slide the color #29 cartridge into the slot on the right side and push down.

Step 7 Push the gray plastic cover down over the #28 cartridge until it clicks closed. Push the purple plastic cover down over the #29 cartridge until it clicks closed.

Step 8 Close the top portion of the printer. Your new ink cartridges are installed, and your printer is ready to use.

You can order them from Lexmark. (A bit expensive.) Links below.

#2 Cartridge

#3 Cartridge

Also available at Circuit City:

#2 & #3 Combo

#14 black #15 color it has to be lexmark ink only...it will not accept any others.....if you have a walmart where you stay at they should have a little machine by the ink cartridges....use that...that is where i got this info from and my printer is printing just fine

Go to Lexmark's Cartridge Finder page. Pick All-in-One in the first box. When the second box appears, pick Lexmark X2500. Then the third box will appear and click it to see all the carts you can buy that work with it.

Looks like it's 28, 29, 31, 34 or 35.
