The waste ink produced by the printer’s cleaning process is absorbed by these waste ink pads when the printer cleans its print head after each printing session. “Waste Ink Pads” is what these sponge pads are called. As a result, Epson equipped the Epson L14150 printer with a large number of sponge pads. Epson L14150 was developed to print a large number of pages, as previously mentioned.
