Countermeasures against cassette paper feed jam 
(TRAY1 , etc.) 
1. Model Name AR-M256M316 
AR-M236/M276 
AR-/235/275 
AR-D11/D11N/D12/D12N/D21/D22/D30/D31 
2. Symptom 
When the remaining quantity of paper in the cassette is reduced considerably, the angle 
of the rotation plate becomes sharp, paper may hit the paper feed roller directly without 
going between the paper feed roller and the separation sheet when it is transported by 
the pick-up roller. 
At that time, for some kinds of paper (especially those with much powder dust), when 
a large quantity of powder dust is attached to the pick-up roller, the transport power of 
the pick-up roller is reduced and paper is not passed through the paper feed roller, 
resulting in a paper jam (TRAY1, etc.). 
3. Description 
In order to prevent the angle of the rotation plate from being sharp even when the remaining 
quantity of paper in the cassette is reduced, the shape of the upper limit detection actuator is 
changed.  
Also to increase the pressure of the pick-up roller onto paper, the pressure of the pick-
up roller pressure spring is increased.  
After change, “H” mark is graved on the upper limit detection actuator.

4. Countermeasures 
Some changes are made in the production of the upper limit detection actuator and the 
pick-up roller pressure spring.  
In the market, however, it is difficult to replace the pick-up roller pressure spring. 
Therefore, the pick-up roller pressure plate is additionally provided as a service part 
instead of the pick-up roller pressure spring.  
To make countermeasures in the market, change the upper limit detection actuator and 
attach the pick-up roller pressure plate.  Attachment position of the pick-up roller 
pressure plate  1. Attach the pick-up roller pressure plate to the pick-up roller unit. 
(Use a screw (XHBS730P06000, M3 x 6).) 
 
 
2. Mount the pick-up roller unit with the pick-up roller pressure plate attached to it on 
the cassette base plate.
