3–58 Operator ManualOperator Menu⇒ VFUDetect DistanceThis parameter sets the vertical distance from the TOF to the position where thepaper is squeezed during a Detect operation. The allowable range is 0 inches tothe current form length, with increments in tenths of inches. The default value is2.0 inches. The print gap is detected at a point away from the perforation inorder to avoid false readings that could be caused by uneven areas around theperforation. The default distance of 2.0 inches is usually adequate unless thereare forms anomalies (such as an attached card or an envelope window) in thatarea.VFU Category (Vertical Format Units)Use the Arrow and Enter keys to selectMenu => Operator Menu => VFU to gethere.VFU EnableA Vertical Format Unit is a means forloading sets of vertical tabs. These vertical tabs define various parameters of aform and apply only to the emulations which make explicit use of the VFU chan-nels. Setting this to Enabled causes the printer to use the last loaded EVFUinstead of using the Form Length, Top Margin, and Bottom Margin settings.When an EVFU is loaded, this parameter is automatically set to Enabled. Thedefault is Disabled.VT Channel (Vertical Tab Channel)You can select which VFU Channel is designated as the Vertical Tab Channel.This parameter applies only to the emulations which make explicit use of the VFUchannels. Options are 1 - 12 and Unused. The default depends on the emulationas defined in the table on page 3-57 under Ser/Par Emulation.Skip WhenThis parameter applies only to the emulations which make explicit use of the VFUchannels. It designates where the Skip Length distance will begin - before or afterthe Bottom of Form channel. The Skip location is determined by using thedesignated Bottom-of-Form Channel in the downloaded VFU. The Skip Whenonly functions when the VFU Environment is Enabled. The default depends onthe emulation as defined in the table on page 3-57 under Ser/Par Emulation.
