18. Unlock the differentials on the input and output spindles. 19. Go to the front panel and select Carriage beam position > Move to printing (normal) to lower the carriage beam into its normal position, close to the substrate. This process takes about 2 minutes to complete. NOTE: The Move to printing (custom) position allows you to set the printhead-to-substrate distance for thick substrates or substrates that may wrinkle in the print zone, to avoid ink smearing. Be aware that raising the printhead from the substrate may give reduced print quality. WARNING! Do not insert your hands or anything else into the printer while the carriage beam is descending. NOTE: If you are printing on a heavy roll, such as Self Adhesive, in order to reduce the risk of substrate jam, we recommend adding an output diverter and increasing the vacuum level. 20. Go to the HP Internal Print Server and press the Load button. The printer rotates the rolls to check their diameters, and it also checks the width of the roll, the winding direction, the vacuum and the substrate advance calibration (this takes 1-2 min). NOTE: Some substrates (such as transparent substrates) cannot be measured by the printer in this way. In such cases, you will be asked to enter the required information manually. Use the scale on the curing module to see the value for the right-hand edge that must be entered manually in the HP Internal Print Server. Handle the substrate ENWW Load a roll into the printer 47
