The print quality is not in question. Same quality as Mimaki. We put the spindle in and start pushing it in slowly according to to directions until it grabs it. Trouble is decal substrate rolls back off the backer before getting to the point where the rollers grab it. Banner stock seems like it's not stiff enough to feed in. It buckles before the pinch rollers can grab it too. Tried lifting the pinch rollers but still won't feed in without binding.
Loading procedures for the HP Latex printers are significantly different than for other brands of outdoor-durable printers, which typically have a rear-to-front print path. The HP Latex machines all use a front-to-front paper path which can be a challenge for some who are used to the back-to-front paper path. Here is the media load technique that I typically teach to new users to HP Latex machines:
1. Use the
Assisted Manual Load approach, versus the Automatic load. This approach prompts the user to lift the big blue lever, to allow the media to more easily pass through the paper path, which is not straight. This approach does not rely on the rollers to advance the media, but instead the user is pushing the media from below, through the entirety of the paper path. This path includes pushing the paper through the curing unit so that it is extending out of the front of the printer (see attached image), before lowering the blue lever to secure the media. If desired, you can align the right edge in the front, with the right edge that feeds off of the roll to ensure that the media is straight and not skewing.
2. Use the Edge clips (see screen shot) with most semi-flat medias (SAV, banner, films, papers), but not with textiles.
3. After the media has successfully loaded and the printer is in a ready state, go to the Substrate Menu > Move > and back up the media to reduce the amount of wasted media at the lead edge. I would advise that the front edge of the media be entering the curing unit when this movement is completed, as some media, particularly reverse-wound banner PVC, that will not navigate properly into the curing unit if the lead edge does not start in the curing zone. Some medias (3M IJ35) I would recommend advancing a bit farther than other medias (cast films).
These practices will significantly reduce head strikes at the start of print runs, which can otherwise happen when these recommendations are not put into play. Using the right techniques, and a bit of patience, anyone can learn to properly load media into Latex 300 series machines with confidence.
