Each barcode is 50.8 mm (= 2 inches) in height and 10 mmin width.[86]The proper positioning of pages of unperforated paper is carried out as follows:■Unprinted paperPTL marks are created by the printing system (paper transport tractorless). Theposition and size of these rectangular areas can be set individually in thesub-menu = .■Pre-printed positioning marksThe printing system can be set to the position and size of positioning marksalready on the paper in the following menu: Mark>.Note:Optical monitoring can be switched off in certain cases when using unperforatedpaper. However, we recommend that you always use the standard setting, especiallywhen printing confidential and/or personal data, e.g. invoices, account statements,tax statements, etc.Only the interplay between the electronic control and the optical synchronizationmark monitoring guarantees a correct allocation of printed front and reversesides.The standard setting is selected in the menu: = and = .Synchronization mark barcode[204]
