Service Manual

Note:  Check the AC line voltage. The voltage should be within the 
following limits:

100 V ac - 127 V ac for the low voltage model printer

200 V ac - 240 V ac for the high voltage model printer

Model E312
HVPS

Measure the voltages at CN2 of the 
HVPS. CN2-3 measures +5 V dc 
and CN2-4 measures +24 V dc. If 
the correct voltage is present, check 
the continuity between the following 
connector locations:

CN2-3 - CN1-17
CN2-3 - CN1-19
CN2-4 - CN1-2
CN2-4 - CN1-4

If any location does not measure 
continuity, replace the HVPS.

Model E312
HVPS to Engine Board Cable

Replace the cable if it does not 
measure continuity.

E312
Engine Board

 Measure the 

voltages on CN11. If any voltages 
are incorrect, replace the engine 
board.

Model E310 & E312
LVPS Fuse

Check the fuse on the LVPS for 
continuity. Replace with the 
appropriate fuse if blown. If a fuse 
blows again after being replaced, 
install a new fuse and go to 

 and check the engine/

LVPS board output.
