Residual-media jam
If the top-of-page sensor (PS103), the fuser-delivery sensor (PS108), or the reversing-unit jam
sensor (PS111) detects the leading edge of the media at the start of initial rotation, the
microprocessor on the dc controller PCA identifies a residual-media jam.
In addition, if the fuser-delivery sensor (PS108) does not detect the leading edge of the media, within
2.1 seconds after the top-of-page sensor (PS103) detects the leading edge, the microprocessor on
the dc controller PCA identifies a residual-media jam.
Whenever the MFP is turned on or a print sequence begins, if the pre-feed sensor (PS102) detects
the presence of media, an automatic-delivery request is sent to the formatter. The dc controller PCA
drives each motor, and the residual media is delivered to the output bin. Normal printing can continue.
