Printing is faint even with new cartridge

SOURCE: Lexmark E320 - new cartridge poor print quality

Hello,

Have you cleaned the print head surface lately? It is located directly above the top of the toner cartridge which you need to remove to do this right. Now using a dry soft cloth reach inside and find the narrow slot and carefully go back and forth with the cloth (sharp metal edges be careful). If this does not solve the problem next try removing the toner cartridge and clean the metal contacts inside the printer on your bottom left side when looking into the open printer also it would pay to remove the transfer roller on the bottom inside this has two black tabs that release the roller the one on your left (again looking into open printer) should have a metal strip that should be free of toner on both sides this will also cause poor print.

Luck

SOURCE: Printer doesn't print even with new ink cartridges.

Take out the Cartridge & get a new one if the problem persists then get the printer software reinstalled & if still it is not printing then clean up the cartridge head with cotton swabs dipped in hot water!
This should clean the head & black will be on paper

DO THIS AS FINAL REFUGE
If still its not working then there's some problem in the copper contact surface in the printer on the cradle so get a new Printer.
