Need Help HP 1500 Latex print error

I hate to be that guy, but have to you tried to doing a hard restart/ reset? Completely pull all power from the machine for 20-30 seconds? I dealt with an earlyer model HP grand and it tossed me so many software issues and I wasted so much time inspecting files about it. If a hard reset doesn't work, I would say to start look for unneeded or unwanted media sensor that HP's engineers live to waste their time on while making sure that your hands will bleed if when you have to do real service work on your plastic printer for dummies.

Does yours have the mechanised lifting top or did they axe that waste of time?

 

I had some weird quirks with the grand latex I used to run, I never figured them out, but I managed to make them work. That HP RIP software looks simple, but has a lot of quirks, you might spend more time reviewing every option it offers to see if something not relevant may be holding it up. I remember rebooting the software and loading the damn thing by myself more than actual time I ever spent running it.

Please share your findings.

 

Does it happen on all print files? I had a weird issue with my 3200 where some files name would give a strange error. In the folder, there are four files that correspond to a job. I renamed them to like A.ext etc.
