Secondary transfer roller engaging/disengaging detection
The DC controller monitors the secondary transfer roller engaging sensor (PS16) when the
secondary transfer is completed.
The secondary transfer roller engaging cam has the secondary transfer roller engaging flag on its
shaft. When the secondary transfer roller is engaged with the ITB, this flag shields the PS16 and
the SECONDARY TRANSFER ENGAGING DETECTION signal (T2SNS) is output (condition “H”),
and vice versa when the roller is disengaged (condition “L”). The DC controller monitors the
position (engagement) of the roller based on this signal.
The DC controller judges the engagement/disengagement mechanism faulty and sends the error
message to the formatter when the T2SNS signal is not input/output within a specified time during
the engagement/disengagement operation.
