Check for any incomplete connection or skew insertion, and
examine the cords visually to see if they have any assembling
problem.
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, 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, 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
Short-circuiting between pin 5 and FG
Short-circuiting between pin 6 and FG
Short-circuiting between pin 7 and FG
Short-circuiting between pin 8 and FG
