This does not really belong here but I did not want to start a new thread.
I bought a Lexmark Z25 just about a month ago and printed only about 20 times only during that period. Suddenly, my printer stopped printing black colors properly. I cleaned the nozzles as per the usual procedure but to no avail. The printing status shows that I still have 50%. I did another technique wherein I switched the slots of the black and color cartridges. The color is printing everytime. This proves that it's not the cartridge slot but the black cartridge itself that has a problem. I tried to clean the copper contacts of the cartridge but it still didn't work.
Did the cartridge dry up cuz I didn't use it that much?
Does anyone know of any other technique which may prove useful in solving my cartridge dilemma?
I don't want to buy another cartridge as I know I didn't use it much (I still have 50%). A new black cartridge costs about 75% as much as a brand new Z25 printer.
Remove the cartridges from the printer. Take a dry lint free paper towel and gently wipe the contacts on the back of the cartridge (not the bottom from where ink is present). Wipe the contacts inside the printer (on cartridge carrier). Install the cartridges. Try to print.
If this does not resolve the issue, please begin by disconnecting the power supply from the wall (not the back of the printer) for at least "30 seconds." Then plug the printer back in and follow these steps:
1. Turn the power to the printer "off."
2. Press and hold the "Paper Feed" button.
3. Press the "Power" button once while continuing to hold the "Paper Feed" button.
4. Keep holding the "Paper Feed" button until one sheet is cycled through.
5. The test is continuous.
The self-test should at least print out a set of either a solid black or solid color bars, if not both. Should this test fail, try it again without cartridges installed. If the self-test still fails to take paper in and make sounds like the carrier is moving across the paper, this is a hardware issue, and the printer will require service. If the self-test completes without any cartridges installed, run the self-test again with only a color cartridge installed. (If you have both black and color cartridges, after this test, run the test again with just the black cartridge installed.)
If the self-test prints, but has lines or smudges or other print quality issues it is problems with your black or color based in the printer, or communications with your computer, or the computer's software. If the self-test prints your test bars clearly, the printer hardware is not at fault. The issue may be a communication problem, or perhaps a software conflict.
