2. Description: 
The following may be the cause of contamination on the paper surface. Please see below   
  and 
implement 
countermeasure. 
 
 
For Fuser Units with a separator plate, micro sized toner contamination may accumulate   
 
 
on the separator plate during regular paper feeding. A large amount of toner will   
 
 
accumulate on the separator plate when there is poor fusing of toner to the paper or   
 
 
when a setting is improperly set such as (incorrect paper type setting). 
 
 
The accumulated toner melts down while the temperature is set to high and eventually   
 
 
transfers to the paper. The fusing web may also be contaminated and trigger noise. 
 
 
Please clean the separator plate when you perform maintenance or service on the Fuser   
  unit. 
 
 
When you do, remove the separator plate clean both front and back surface with   
 
 
alcohol. 
 
 
If you don’t know how to remove the separator plate, please refer to the section in   
 
 
Service Manual with description on disassembling/assembling of Fuser unit. 
 
 
The service manual for MX-C250/C300 series does not describe how to   
 
 
disassemble/assemble the Fuser Unit, so please refer to the instructions below. 
 
 
 
Note 1: One of the causes of fusing failure is the incorrect paper type setting. Please tell   
 
 
              your client to set the paper type properly when using special type papers such as   
 
 
       heavy paper.

       MX-2640N/3140N/3640N as announced in the T/R. Although it has been implemented,   
 
              please make sure to check for the contamination on separator plate and fusing web on the   
 
              Fusing unit when you are upgrading to this firmware.   
 
              If contaminated, clean the separator plate and roll up the web roller sheet.
