I would definitely search on google for your issue. Also I would check your ink cartridges because HP gets bad ones once and a while. 1 bad one can cause havoc to all the other ones that are run by the same system. I am an HP factory trained repair tech but work for a small company. I do not work on latex machines though. The dealers pay big dollars for techs to get trained on each model and then pay techs fairly well to keep us. We charge enough but keep in mind down time. Sometimes it is better to fix it yourself and sometimes it isn’t. Most things aren’t rocket science but sometimes it gets tricky. It might even be a valve for pressure associated with those inks. It does get a bit complicated. Good luck.
United Reprographic. How about you? We specialize in wide format and cover the whole state but we do mostly architectural printers not sign printers like Latex.
These are called the PIPS we have to change ours quite often it’s easy to do. What error code is it giving?
