Why is my Epson L3210 printing faded or streaky?

Several factors can cause faded or streaky prints on your L3210. Low ink levels are a common culprit, so check and replace any empty cartridges. Also, ensure the print heads are clean. Run a print head cleaning cycle through the printer's settings menu. Incorrect paper type settings can also cause issues – make sure you've selected the appropriate paper type for the media you're using. Finally, check for clogged print nozzles using the deep cleaning function.
