SERVICE AND MAINTENANCE

When doing some lighter 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

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. The table below shows which printing mechanism made which
dot.
