Fujifilm Frontier 350 and 355 has the same printer/processor ( LP1500SC ) . Dfferent only scanners ( SP1500 and SP3000 ) .
Fujifilm Frointier 370and 375 has the same printer/processor ( LP2000SC ) . Dfferent only scanners ( SP2000 and SP3000 ) .

The most parts on LP1500SC and LP2000SC are the same. LP2000SC is just a little faster. Parts can use on any of them.

These printers for laser do not have separate power supply. Printers have power supply box, where mounted two Alpha power suppliers. 

E-2510 means abnormal data on G Laser. LDD20 board can't read data from G laser head.
E-2511 means abnormal data on B Laser. LDD20 board can't read data from B laser head.
Can be bad connector LDD6 ( G ) , or LDD9 ( B ) connections, faulty LDD20 board, faulty G laser head, missing 5V power supply, or burned fuse CP805 ( on LDD20 ) .

E-2520 means R laser(R-LD) current exceeded. Red laser current is out of limit. Can be faulty R laser, LDD20, or LDD5 connection. This error can be with E-2509 error ( abnormal data on R  Laser ) . Then can be bad LDD4 connection, faulty LDD20, missing 5V power supply, or burned fuse CP805 .

Almost impossible, that all three laser heads are faulty. Can be missing 5V , burned fuse CP805, or faulty LDD20 board. Check if on head you have 5V power supply ( LDD4 pin1, LDD5 pin1, LDD9 pin1 ) . If do not have then check fuse CP805 ( on LDD20 ) , or 5V on board input. If have 5V - replace LDD20 board.

By the way - on Fujifilm 390 ( printer LP2500SC , scanner SP2500 ) used the same laser unit and the same laser board ( LDD20 ) . The most parts on LP2500SC are different, but few parts are the same.
