Detection timing<\/td>-At the completion of transfer belt pressure\/retraction operations, the 1st transfer pressure sensor\/K (PS51) or the 1st transfer pressure sensor\/YMC (PS52) is not in the status corresponding to each of the transfer belt pressure\/retraction operations. See the table below.
-Even after a predetermined period of time has elapsed since the transfer belt starts pressure\/retraction operation, the 1st transfer pressure sensor\/K (PS51) or the 1st transfer pressure sensor\/YMC (PS52) is not in the status corresponding to each of the transfer belt pressure\/retraction operations.
