Hi everybody! We have a HP Designjet L26500 and A HP Latex 370 printer. I am in search of end caps. I haven't been able to find any online and HP hasn't been any help. When looking at the printer, it's the black end caps that go on the right side of the spindle used to hold the vinyl that you are printing on. Over time they have broke where the blue tabs no longer work. I make due with them for now but definitely need some new ones! Any help on where I can purchase these would be greatly appreciated!
