It's been my experience when an inkjet printer produces unfavorable printing results ("scan lines or no color) the most common cause is clogged print nozzles. The most common cause of clogged print nozzles is lack of use and the ink dries and hardens in the nozzles.
Your particular model of Lexmark as well as other brands generally have a utility to assist in unclogging the jets by forcing ink through the nozzles. This does "waste" ink, but it is the "easiest" way to attempt in unclogging the nozzles.
For your model try the following: (This is an excerpt from the Lexmark site.)
- Load paper.
- Click Start Programs Lexmark 4200 Series Lexmark Solution Center.
- From the Maintenance tab, click Clean to fix horizontal streaks.
- Click Print. A nozzle page prints, forcing ink through the clogged nozzles to clean them.
- Print your document again to verify that your print quality has improved.
- If you are not satisfied with the print quality, continue with step 7 and then print your document again.
- Wipe the print cartridge nozzles and contacts:
- Remove the print cartridges.
- Dampen a clean, lint-free cloth with water.
- Gently hold the cloth against the nozzles for about three seconds, and then wipe in the direction shown.
- Using another clean section
of the cloth, gently hold the cloth against the contacts for about
three seconds, and then wipe in the direction shown.

- With another clean section of the cloth, repeat steps c through d.
- Let the nozzles and contacts dry completely.
- Reinsert the print cartridges.
- Print your document again.
- If the print quality does not improve, repeat step 7 up to two more times.
- If print quality is still not satisfactory, replace the print cartridges.
