A3/A4 inkjet printer (Presteigne LD8)

Brother inkjet printer/copier/fax + half a dozen inks. Prints A3/A4 and smaller sizes with auto double-side printing, AirPrint etc
Was working fine until I did a bit of what I thought was gentle cleaning inside, now it just gives a paper jam message and refuses to cooperate!!
I’ve bought a replacement now - if anyone wants to take this to fiddle with it and see if you can get it working again you’re welcome to have it. Otherwise it’ll go to printer heaven (Llandod HWRC!) next week.
