2. Insert in its place the wiper roller, covered in foam, with the gear on the right-hand side. 3. The printer detects that the wiper roller is in use, and displays it as available in the Substrate and Loading screens. It also displays the length of substrate that has been printed using the wiper roller. 4. Continue with the usual substrate loading procedure. Tips ● After loading, the first 400 mm of substrate between the wiper roller and the print zone has not been wiped. You can add that distance as a top margin in your RIP, or you can move the substrate back and forth from the Substrate menu to wipe that area before printing. ● 800 series only: To obtain the most benefit from the wiper roller, ensure that the pivot table is in the inner position, so that the substrate has maximum contact with the wiper roller. ● For some vinyl substrates, you can optimize performance by increasing the input tension to 15 N·m in your substrate preset. See Modify a substrate preset on page 94. ● If the wiping is not effective enough, consider either using a slower print mode or adding delays between passes in the substrate presets to allow more passes of the roller per substrate advance. Replacement ● ● ● The wiper roller foam does not last indefinitely and should be replaced after extended use. The printer tracks the length of substrate wiped by the roller, and displays a warning when replacement is due. Extract the right end cap with the gear from the old roller, and insert the gear into the replacement unit. Then reset the Replace wiper roller counter in the printer's front panel.
