 ==== Cleaning the printer ==== ==== Cleaning the printer ====
 Over time, the printer will fail to perform due to collection of dust. We imagine sweat particles will cause friction on the moving parts of the printer and this hinders performance. So in many cases throughly cleaning the printer ends up reviving a printer that seems broken.

 +NOTE: **Defragmentation** is a normal operation of the GK420t printer.  The printer will defragment its memory both after a factory default and when the printer detects that a defragment is required.  When the printer is in this condition, allow it to finish defragmenting. If this warning occurs frequently then refer to the printer user guide as some label format changes could resolve this.
