Why isn't yellow ink coming out of my Epson L3110 printer?

Several factors can cause yellow ink to not print on your Epson L3110. First, check the ink levels for the yellow cartridge. Even if it appears to have ink, it might be empty or depleted. Second, ensure the yellow cartridge is properly installed and not blocked. Third, perform a print head cleaning cycle specifically for yellow. This is usually accessible through the printer's menu or the Epson iPrint app. Finally, check for any clogs in the print head nozzles. If cleaning doesn't help, a more thorough cleaning or replacement of the cartridge may be necessary.
