Epson's SC-P5000, SC-P10000, and SC-P20000 printers are equipped with an anti-static sheet in the paper tray that prevents dust from entering the printing area. Over time, dust may accumulate on this sheet, reducing its effectiveness. The cleaning sheet is therefore designed to quickly and easily remove this dust. The sheets are supplied in sets of five. Each sheet has an adhesive surface designed to remove dust and other particles from the anti-static sheet. Cleaning is quick and easy, and a single sheet is usually sufficient for a complete cleaning, which should be carried out at least once a year.
