Using water can really do damage, especially if it was not completely dry. Ammonia is way better, rubbing alc is ok. Try another new color cartridge, many times cartages are bad when you get them, also go to Setting / devices / and see if black only is selected as default.

If you have the old cartridge, put it back in the machine and see if you get the same message. If the message changes, then the problem likely has to do with the new cartridge and something being wrong with it.

Ensure that the proper paper size is being used in the ADF.

Are the paper guides on the ADF tray properly adjusted?

Inspect the ADF separator roll and ADF separator pad for wear. If they are worn,

replace them. If they are dirty or have a buildup on them, clean them with a damp

cloth.

If the ADF fails to pick check to make sure that the paper height in the ADF input

tray is beneath the height marker on the ADF paper guides.

Inspect the paper present sensor on the ADF.

• Check the flags on the sensor. Are they able to move freely? If the sensor

flags are damaged, replace the ADF assembly.

Make sure the ADF cable is securely connected to the ADF and the controller

card.

If the cable is properly connected, perform the following checks:

• Check the ADF cable for continuity.

• Check pin 1 on controller card connector J2 for +5V.

• Pin 3 should be ground.

If voltages are present, replace the ADF.

If replacing the ADF does not fix the problem, replace the controller card.

If the ADF is multi feeding, check the ADF pick roller and pad for dirt. Remove

them from the MFP, and clean them with a lint free cloth and isopropyl alcohol.

If the leading edge of the paper is damaged, instruct the user to lessen the

number of documents being copied from the ADF at one time.

If there are excessive misfeeds from the ADF, verify that the ADF paper tray and

extender are properly installed.

Skews and jams at the ADF paper present sensor might be caused by an improperly closed ADF cover. Ensure the ADF cover is closed properly.

I suggest you find an answer pretty quickly as your printer uses its own ink to clean the heads. An expensive process.

1. You can change the copy count under the copy settings in your Lexmark device. 2. Power off the printer. Tap and hold the Go and Return buttons at the same time. 3. Turn on the printer and release the buttons. Now the printer prints the Performing Self Test page and modifies the copy count. 4. Go to Diagnostics and check the page count. 5. Tap Return and select the Preview menu. Choose the Reset Maintenance Count option and press Select to set the count to zero. Print a test page and complete the setup.
