Solenoid?

Everything camera related. Includes triggers, batteries, power supplies, flatbeds and sheet-feeding scanners, too.

Hi dpc, could you share the technical details by a schema or photo of your solenoid setup? What kind of solenoids do you use?

For me sounds nice the mechanism operating the shutter at the end, when the printed material achieve the proper pressure against the glass. Any contribution I would share it here documented in 3D via Sketchup.
How about placing a small white colored profile piece / clip, which will slide between the glass panels so it can be placed above the bottom and inner margin of the book.
How about putting your pressure sensitive sheet-switch between the book and the cradle?

Great idea! I just have to check how much padding between the conductive contacts is needed to deal with different weights of books.
