INCORRECT DETECTION OF "PUNCH DEBRIS 
FULL" IN DUST BOX.

CCE-623 
 
1. Model Name:
 MX-PNX1A/B/C/D 
(Options for MX-1800 Series/2000 Series/3000 Series/4000 Series/500* Series) 
 
2. Symptom:
 
The punch unit (MX-PNX1A) for the inner finisher may display the message "Check the punch 
debris unit" because it detected "punch debris full" although the dust box is not filled with 
punch debris. If this message is displayed, the punch function may be disabled. 
The punch unit for the inner finisher incorrectly detects that the dust box is filled with punch 
debris if the movement of the punch debris diffusion plate slows down. The movement of the 
punch diffusion plate slows down because the spacing between the punch debris diffusion 
plate and connection gear becomes too narrow if the dust box moves to the right when 
mounted. 
If the dust box moves to the left, however, the punch unit does not incorrectly detect "punch 
debris full" because a gap is secured between the punch debris diffusion plate and connection 
gear and the movement of the punch diffusion plate becomes smooth. 
 
 
 
 
 
3. Description:
 
To prevent the dust box from moving to the right when mounted, we pasted a sheet to the right 
side of the dust box, moved the dust box to the left, and secured a gap between the punch 
debris diffusion plate and connection gear to smoothen the movement of the punch debris 
diffusion plate. 
We also found that if there is a sheet in a position where the punch debris diffusion plate 
contacts and the punch debris diffusion plate is caught in the sheet, the movement of the 
punch debris diffusion plate slows down. For this reason, we have abolished the sheet. 
 
Additional sheet (thickness: 0.5 mm)
