Models E310 & E312
Transfer Roller

This problem is most likely due to a 
worn transfer roller. A worn transfer 
roller causes the printer to run hotter 
than required for the media being 
printed. Excessive heat can cause 
paper treeing problems, poor 
stacking or curl.

Blank pages can be caused by a 
defective printhead assembly, high 
voltage power supply or engine/
LVPS board. Disconnect the 
printhead cable from the HVPS and 
measure the signals on connectors 
CN3 and CN4. Go to the 

 in the connector 

locations chapter and check the 
voltage measurements. If the 
voltages are correct, check the 
printhead cable for continuity. If the 
cable measures continuity, replace 
the printhead. If the cable does not 
measure continuity, replace the 
cable. If the voltage measurements 
are not correct, replace the HVPS. If 
the problem still exists, replace the 
engine/LVPS board on the model 
E310 or the engine board on the 
model E312.
