Rank<\/td>B<\/td><\/tr>
Trouble detection condition<\/td>\u2022 The 1st transfer pressure sensor\/K (PS51) does not detect “switch from retraction to pressure” or “switch from pressure to retraction” within a given period of time during an initial position return.
\u2022 The 1st transfer pressure sensor\/K (PS51) does not detect switch from retraction to pressure within a given period of time after pressure operation has started.
\u2022 The 1st transfer pressure sensor\/K (PS51) is unblocked even after a given period time when pressure operation has finished.

 Procedure<\/h2>\n\n\n\n
  1. Check the connector between M21-relay CN428-MFPB CN19E for proper connection and correct as necessary.<\/li>
  2. Check the connector of M21 for proper drive coupling and correct as necessary.<\/li>
  3. Check the transfer roller pressure gear of the transfer belt unit for proper engagement and the roller for rolling operation, and correct any faulty motion.<\/li>
  4. Check the connector between PS51-relay CN297-MFPB CN27E for proper connection and correct as necessary.<\/li>
  5. PS51 I\/O check, sensor check
