on CU board
43085101TH Rev.1
Confirmation Tasks
Check to see if the 2nd tray unit in use conforms to the
C6100 specification (A unit conforming to the C5800n
specification cannot be connected).
Check to make sure that the cord is properly connected from
the 2nd connector of the PU PCB (PRX PCB) to the 2nd tray
PCB.
Check to see if there is any foreign matter trapped in the
connecting part of the square connector.
Check to see if the pins of the square connector are broken.
Check the signal delivered through the 2nd connector of the PU
PCB (PRX PCB).
Pin 5: TXD(PUfi2nd)
Pin 3: RXD(2ndfiPU)
Confirmation Tasks
Check visually the connected state of the FFC.
Unplug the FFC of the head, and check for any wire breakage or
peel-off of the covering along the cord.
Check voltage is 5V between capacitor
CP7(C5800),CCP1(C6100)(See section 7.6)
