I just installed two refilled lexmark cartridges color and black yet printer is reading black cartridge missing and color cartridge missing. I am unable to print

Re-install cartridge or if not original Lexmark cartridge, aftermarket refilled, the printer won't recognize the refilled cartridge.

Page 50 has full instructions.

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.

If you have refilled the cartridges 28 and 29, it's pretty normal that your printer won't print. Those cartridges are not for refill (they can be refilled, but won't work once the printer says they are empty). If you have refilled a 28A and 29A and it doesn't recognize the one of the cartridges, try removing them and clean the electric contacts with a dry cloth. Put them back in. If that doesn't help, I suggest you buy a new cartridge.

I own a Cartridge World ink refilling store and I can't refill the Lexmark 36 and 37 cartridges. Your printer deactivates the electronics on this cartridge when the ink levels get low. Your printer needs a black and a color cartridge with functioning electronics to print. I NEVER recommend Lexmark printers. They are poorly made, don't accept refills easily, and have the most expensive ink across manufacturers and it is designed to clog your cartridge unless you use it quickly. If you keep this machine you are stuck buying Lexmark brand ink (the return program cartridges are a little cheaper though).

Exchange the cartridge for another new Lexmark cartridge. I think Lexmark printers have gotten so finicky about kicking out refills that they sometimes reject original cartridges. I own a cartridge refilling store and I've had a couple original Lexmark cartridges returned because the printers didn't recognize them.

These are the instructions for X2500 Printer
1.Press the "Power" button to turn on your Lexmark X2500 3-in-1 printer.
2.Open the top portion of the printer to reveal the ink cartridges.
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.
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.
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.
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.
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.
8.Close the top portion of the printer. Your new ink cartridges are installed, and your printer is ready to use.

What you need is to reset the ink level:
1) Goto the Lexmark Solution Center application.
2) Press button Maintenance>Install a new print cartridge, follow the instruction on screen. U may then have your new full ink level. Note: u only can reset to full level, cannot customize the level by your own.
Hope this help.

Just a shot in the dark, was it a refilled ink cartridge. I know HP has a problem detecting the remanufactured cartridges from time to time. And too, if it is not refilled cartridge perhaps you just have a bad cartridge.
Oh, of course Julie remembered to pull the tape off of the bottom of the ink cartridge, correct?
Hope this did some good, please leave rating,
thank you kindly.

I would like to inform you that Lexmark does not support refilled cartridges and it may void your printer warranty. Please use Original Lexmark Cartridges.
