I worked in IT support and engineering for a UK Olivetti dealer / distributor in the 1980s/90s. As such I had access to all sorts of Olivetti kit in various states of functionality. At one time, my home PC was an Olivetti M280 case with an M380 (386DX) motherboard and EGA display adapter. It had a colour monitor and the ANK 27-102 keyboard - it was a 'top end' hybrid for its time that I'd put together from several non-working machines..

I also had a 'faulty' Olivetti inkjet printer that was written off under warranty with a mysterious fault. I eventually managed to fix it by bending the metal paper detector arm so that it slotted properly into the optical sensor - it was a little out of whack and the sensor sometimes couldn't work out whether there was paper in the tray.
