: How often do I need to change the cleaning sheet - how many uses can I get from each sheet? Do I need to use a clean sheet each cleaning?
Answer : It is recommended to use cleaning sheets once every daily duty cycle or whenever you notice your scanner becoming dirty. While it is recommended to use a clean sheet with each cleaning, there is no exact rating for the number of times you can use a sheet before it is worn out, which depends on how dirty your scanner is. Use the sheet until it stops cleaning the scanner effectively. If the scanner still has dirt after that, you can either use a new sheet or clean the remainder manually with wipes.
