Nd Btr Contact - Xerox DocuColor 2240 Service Manual

9-342 2nd BTR Contact

The 2nd BTR did not reach the contact position.
Initial Actions
• Clean the 2nd BTR Retract Sensor
• Check the 2nd BTR gears (PL 2.8) for breakage.
Procedure
Enter dC330 [009-200]. Open the Left Cover and block and unblock the 2nd BTR Retract Sen-
sor with a piece of paper. The display changes state.
