4. SERVICE AND MAINTENANCE

When doing some ligther service or maintenance tasks, it can be enough to remove the side plates on

the cover. But for bigger operations we recommend to also remove the top cover. Please see section

2.2. ‘Removal of the side panels’ on page 11

on how to do this.

If possible, keep the operator panel fastened on its bracket during service or maintenance.

But if for some reason the operator panel is unscrewed, you can place the operator panel beside the

printer so that you are able to connect the cables. However, observe that the operator panel is an

electrical board, and MUST NEVER BE LAID ON A CONDUCTIVE SURFACE! If there is a short

circuit on the board, it might damage the board.

4.1 Printing principle

The figure below is a very simplified version of the printing mechanism in this printer.

The four bars across the paper indicates the magnet racks.

The magnet racks are named from A to D.

Magnet rack A and B make dots on the side of the paper facing down, and magnet rack C and D

makes the dots on the side facing up.
