The Decurler has bothupper and lower decurl rolls that apply pressure tothe media based upon the following:System default•Decurl selections made in tools-mode on the•User InterfaceManual selections made at the Decurler•Control PanelBased on the decurl settings, the Decurler Gateroutes the paper either to the up-curl(Upward/Cupped) path or to the down-curl(Downward/Bridged) path. Pressure then is appliedto the paper to remove any upward or downwardcurl. The paper is then moved from the decurler tothe connected finishing device.From themachineDecurlerPaper pathTo thefinishingdevicePaper curlWhen paper is exposed to heat, the paper losesmoisture and curls toward the heat source. Highcoverage jobs tend to curl more due to the tonerplastification effect on the paper surface. Thesystem tries attempts to reduce this by using amechanical decurling device, located within theInterface Module.Some factors affecting paper curl are:The weight of the paper and/or whether it is•coated or uncoated.The amount of dry ink/toner and the area•being coverage per sheet.How the paper is loaded in the tray.•The atmospheric conditions of the paper•storage room and at the printer location.The amount of heat generated during the•fusing processes.If the curl is unacceptable, you can change thesetting.
