Handle the substrate After you have loaded a roll: ● Make sure that the edge holders are set on both sides of the roll. Do not use any other Edge holder from another printer, only use the edge holders that came with the printer. An incorrectly loaded roll may cause waves or cockles in the substrate, leading to ink smearing and printhead crashes. ● Check the correct carriage beam position for printing: high for thick substrates, normal for others. See Set the carriage beam position on page 25. ● Check that you are using the correct substrate preset in the HP Internal Print Server and the correct ICC profile and other settings in the RIP. ● HP substrates are optimized to provide the best out-of-the-box printing experience with your printer. However, you may want to modify the ink limits or the number of passes; in which case, temperature, vacuum or tensions may need to be adjusted. You can create a new substrate preset from the default preset you are using and make your changes. ● Use the HP Internal Print Server to check that any required calibrations have been done: color calibration, substrate-advance compensation, printhead alignment. See the Maintenance and troubleshooting guide. ● For the best print quality, the substrate should stay flat and unwrinkled in the printing zone, the substrate advance should be constant and the substrate should move straight. ● Do not cut off pieces of substrate while the substrate is loaded into the printer. This may cause the remaining substrate to jam. After printing, try to allow 24 hours before stacking, folding or rolling printed substrates. NOTE: Printing on porous substrates may result in visible vapor being generated from the waterbased ink.
