1. Model Name: 
  MX2310U, MX-230U1 
 
2. Symptom:
 
Toner dispersion from the 1st transfer unit may contaminate the transfer mode detector 
(CL/BK) mounted on the main frame rear side, generating false detection. If false detection is 
generated, “L4-06” trouble code may occur. 
 
3. Description:
 
To prevent the transfer mode detector (CL/BK) from being contaminated by toner, we have 
added a sensor sheet and sensor molts to the rear side (transfer frame CL) of the 1st transfer 
unit. For pasting criteria, see the accompanying sheets. 
Note) Clean the pasting surface with alcohol, etc., before pasting.
