cord
Check to make sure that none of the cords is caught
under any assembled part of the printer.
Unplug the HOP connector of the PU PCB (PRF PCB),
and confirm the following on the cord side:
Short-circuiting between pin 1 and FG
Short-circuiting between pin 2 and FG
Short-circuiting between pin 3 and FG
Short-circuiting between pin 4 and FG
Unplug the BELTIDUP connector of the PU PCB (PRF
PCB), and confirm the following on the cord side:
Short-circuiting between pin 1 and FG
Short-circuiting between pin 2 and FG
Short-circuiting between pin 3 and FG
Short-circuiting between pin 4 and FG
