Once you get the top part lifted from the rest of the printer, you must carefully pull out the few connectors that attach to the logic board from their sockets. There are four screws total to remove the top, and you can use a torx bit, or if none handy, the right size allen key. Reach behind the control panel and gently push a clip to release the panel. Open the scanner lid and the ink replacement door. (and a soldering kit if you don't already have one)
It will cost you all of 60c worth of components. It's an easy fix, if you're not afraid to solder one component. It's 330uF 6.3V, but I pu in a slightly bigger one (16V, all they had in 330uF) and it works perfect now. There is only one to replace on this printer, and it will probably look curved on the top (indicating it is blown).
It was a bad capacitor on the logic board (brand TEAPO). Business PCs, Workstations and Point of Sale Systems.Printer Wireless, Networking & Internet.DesignJet, Large Format Printers & Digital Press.
