Editing Quickstartguide:UVFlatbed (section)

===A word of context===

To make you understand the operation of the flatbed better, here's a short explainer as to its way of working: a subject (a box, a piece of metal, a book cover, whatever) is placed on a printer bed ('''the table''', in Roland-world) that moves the subject deeper into the machine, and underneath a horizontally moving printer head (with UV-light). Once the whole subject has been printed and the job has been completed the table moves back to the front. To ensure good results and to prevent stuff from ramming into the printer head, the flatbed makes use of a sensor in the form of a wide black piece of metal in the back of the machine. The table moves underneath this sensor and if anything on the table (even lightly) touches the sensor, the machine will stop and give a '''table height error'''. The height of the table therefore needs to be adjusted to the material you are about to print on, so that nothing touches the sensor. Keep this in mind for the rest of this guide and when you have to do some troubleshooting.

Alright, now that you have some basic understanding of the flatbed, let's start on the machine side of things.
