I'm having cartridge problems with lexmark z2420 printer

A lot of the ink jet printers have a copper color strap on the ink cartridge this contains the heads. If you are refilling the cartridges or have let the printer sit for a long time the heads can get built up dry ink stuck in them. Try taking the cartridge out and physically cleaning it using rubbing alcohol. If this does not work try replacing the cartridge.

Check all ink cartridges

The problem could be due to a communication failure between the color cartridge and the All-In One (AIO) or by a short in the color cartridge. Here's what you can do:

1. Try to re-seat the cartridges in the printer. Open the printer cover > remove the cartridges > close the printer cover > re-brick you printer by pulling out the power supply - black box behind the printer where the power cord is plugged in, and re-plug after 10 seconds. When the printer turns on, reinsert the cartridges and close the cover. Try to print a document again to verify that the problem is fixed.
   
2. Try to insert a different known working cartridge to identify if it's a faulty cartridge issue.
3. Ensure that you are inserting original supplies. Refilled, re-manufactured or clone cartridges are not recommend for use with your printer. These are unreliable and tend to fail unexpectedly. If you're using genuine Lexmark cartridges yet it continues to fail, please contact the Lexmark Technical Support Center for further assistance.

The problem could be due to a communication failure between one of the printheads (cartridges) and the All-In One (AIO) or by a short in one if the printheads. Please follow the steps below to identify and fix cartridge issues:

1. Make sure the printer is on.
2. Open the printer cover. The print cartridge carrier moves and stops at the loading position, unless the All-In-One is busy. Note: If the carrier does not automatically move to the center, turn off the printer or unplug the printer from the power source and then carefully slide the carrier to the center.
3. Remove both cartridges from the carrier.
4. Close the printer cover.
5. Re-brick your printer by pulling out the power supply - black box behind the printer where the power cord is plugged in to, and re-plug after 30 seconds.
6. When the printer turns on, reinsert one cartridge first. Close the printer cover and check for any errors.
7. If no error appears, reinsert the other cartridge. Close the printer cover.

also clean the gold connectors on the cartridges, and on the carrier also.

You cannot refill lexmark ink cartridges successfully suggest you buy the original as you are not easily going to find generics good luck try and buy the high yield cartridge at least 200-300 pages extra depending on the model

I had a problem with mine also. It kept giving me an unsupported cartridge error. I finally took it back to the store and exchanged it. The replacement works fine.
