4.4 Magnet rack, disassembly, step by step

There are two main reasons for disassembling the magnet rack.

It could be to replace some parts, i.e. a defect magnet, a worn

pivot arm, or it could be for regular maintenance.

The magnet racks can be considered as the parts of the printer

that will have the greatest influence on the dot quality, so it is

very important to know how to deal with them.

Take the magnet rack out of the printer like described in chapter 4.3 “Magnet rack, removal”.

Next, follow the instructions below.

Step 1.

Remove the two bolts holding the sponge list, and then remove the sponge list.
