Hope this helps

please just you scan the object to resuleasion in and dp is 600 to 12oo select and you scane object and aply print is dark is ok.

If the software is installed correctly it should scan from the scanner, otherwise i would suggest using the scan button on the software screen. Make sure all your drivers are up to date!

If you are not using Epson ink, your printer will do this. Epson printers hate knock-off ink. Always use Epson ink if you want to keep your printer working properly. To solve the problem you are having, try cleaning the ink tubes. Make sure you re-install them properly. Hope this helps. Charlene

Open up the document feeder and look for dirt on the scanner glass.

With the Lexmark printers communication subsystem you MUST let the driver ask for you to plug in the printer. DO NOT plug the printer into the USB port until told to do so.

To fix a fouled install :
(1) Uninstall the Lexmark drivers in Add Remove Programs
(2) Shutdown the computer
(3) Disconnect the printer from the USB port
(4) Restart the computer
(5) Run the Driver Installation software
(6) Cancel ALL attempts by windows to auto install the printer
(7) When the sofware asks for the printer connect it and continue

Clean the ADF roller and the far left hand side of the glass, the small strip outside the 'main' panel.

sounds like a resolution issue in the scanner settings.

Dear, after changing the cartridge, printer print a test print. OKAY. Take that test print and put it on the scanner (printed area should on the side of mirror) then press "scan" button on your printer "bottom left". When the light stop fluctuating. Keep out the paper from the scanner. After this Printer will work properly

If the line only appears when the scanner is used & not when printing directly from the computer, you are correct in assuming the problem lies in the scanner assy. There should be mirrors attached to the scanner assy which will gather dust and cause copy/scan problems. Remove the glass & clean the mirrors with a DRY cotton cloth. Do not use any cleaning solution on the mirrors as they are sometimes treated & can be ruined if they come in contact with a cleaning solution. Use the dry cloth to wipe off the lens while you have it apart.Also clean both sides of the copy glass while you have it off. Reinstall glass & test.Cleaning the optics solves the problem most of the time. Good Luck!!
