With the SAMSUNG SF-350, you can save ink by pushing the Ink Save button. The conventional way of saving ink causes lighter lines in printout, which looks jittery. The SF-350 saves ink by controlling the number of each printed dot. As a result, printouts in Ink Save mode are a little lighter and good for printing drafts. Push the Ink Save Button and save printing costs.In Paper Save mode, you can copy 2 pages on 1 sheet of paper (2-up copy). Toll Save allows delayed transmission of a stored document at a discounted rate from the telecom provider. You can set up the time zone depending on the discount time. The Skew-free ADF eliminates the worry of important faxes being unreadable because of off-centered documents. With this function, papers will automatically align themselves when inserted into the machine.
