A sheet folder comprising input rollers, exit rollers and a fold box having a fold plate which is curved substantially along its whole length, wherein the curved fold plate is configured to induce a sheet to curve in two different directions during the folding process. The first sliding member is slidably mounted on the mounting seat. According to embodiments of the invention in one regard, the dynamic DNIS may be associated with that call to the call’s particular destination, such as an automatic call distributor, interactive voice response unit or other resource, during the duration of the call for the operative destination, with other calls being locked out from using that DNIS assignment while the call is in progress. The one sample of the multi-sample pixel is processed by the processing unit to generate processed data for the one sample that represents processed multi-sample pixel data for all samples of the multi-sample pixel or two or more samples of the multi-sample pixel.
