Generally,higher DPI results in a higher resolution, more visible detail in the image, and a larger file size.DRPD Distinctive Ring Pattern Detection. Distinctive Ring is a telephone company service which enables auser to use a single telephone line to answer several different telephone numbers.DSDF Dual Scan Document Feeder (DSDF) is a scanning unit that will automatically feed an original sheetof paper so that the machine can scan on both sides of the paper at once.DuplexA mechanism that will automatically turn over a sheet of paper so that the machine can print (orscan) on both sides of the paper. A printer equipped with a Duplex Unit can print on both sides ofpaper during one print cycle.Duty CycleDuty cycle is the page quantity which does not affect printer performance for a month. Generally theprinter has the lifespan limitation such as pages per year. The lifespan means the average capacityof print-outs, usually within the warranty period. For example, if the duty cycle is 48,000 pages permonth assuming 20 working days, a printer limits 2,400 pages a day.ECMError Correction Mode (ECM) is an optional transmission mode built into Class 1 fax machinesor fax modems.
