13. Once in front of the printer, if you find that you haven't unrolled enough substrate, select Start main roller motion from the front panel to unroll some more. The substrate unrolls only when you pull it. 14. If you are loading a vinyl substrate on an LX850 printer, you are recommended to use the output diverter from the ink collector kit, to minimize wrinkles. 15. At the rear of the printer, measure the distance between the printer's left side plate and the left edge of the substrate. This distance should be at least 145 mm (5.7 in), otherwise the edge of the substrate may go out of the print zone and start touching the printer covers. 16. At the front of the printer, the right edge of the substrate on the empty core should be at the same distance (A) from the right side plate as the distance measured on the input side. NOTE: When loading non-elastic substrates, a difference of 2-3 mm (0.01 in) between the measurements from the rear side plate and front side plate may be acceptable without problems of skew or wrinkles. Rear Front TIP: It is important that tension is uniform across the width of the substrate. One way of achieving this is to take the front substrate edge by its center and shake it alternately to right and left several times while at the same time pulling the substrate until it reaches the core on the output spindle. 17. When the substrate is evenly tensioned, attach it to the empty core with adhesive tape. Tape it first in the center, and then at the left and right sides, making sure not to pull the substrate excessively or leave it wrinkled. Handle the substrate ENWW Load a roll into the printer 41
