Yearly replacement is required for most offices doing between 1 to 100 sheets of folding per day.
Higher volume of folding may require these components to be replaced more often depending on your folding volume.
It is highly recommended to keep at least one back-up maintenance kit on hand should you start encountering mis-feeding of flat stock paper through the top feed tray. The feed wheel and paper separator wears over time with use and in most circumstances - mis-feeding is caused by these two parts.
Replacing these parts is quick an easy to do - and the maintenance package includes full written and image instructions.
The replacement of these parts takes less than five minutes to do.
