The LED strip of the scanner of the new copier in the storage of Carmel hospital [img]https://i.postimg.cc/x1kJ27J4/IMG-8667.jpg[/img] There are two LED strips, which aren't hidden from view: One for the document feeder, and the second for the scanning surface. Unfortunately, I can't turn the LEDs ON by the same way I did this in the former copier. They are ON, only during scanning and self-test.

My latest EPSON printer which has a scanner on top still uses a ccfl

Most current multifunction printers, uses CIS sensor for the scanner, which relies on an RGB LED bar, like my Brother MFC-J4340DW. You printer probably still uses a CCD sensor for the scanner. And as CCFLs with mercury vapour takes a while to run-up, it can't be ON only during the scanning but also when not in use.

Also: The former copier also had LED lighting for the scanner.
