Roll Paper Feed
Roll paper feed starts from the pre-feed position.
! The roll feed motor engages roll feed clutch 1 and turns the feed rollers [1].
! The RF exit rollers [2] feed the paper past the roll exit sensor [3] to the registration
roller. The RF exit sensor checks that the leading and trailing edges of the sheet go by
at the correct time.
! The registration sensor [4] stops the registration roller [5] to correct skew. Then, the
registration roller feeds the paper to the drum [6] and through the T&S unit [7].
! The cutter [8] cuts the paper at the length specified for the job. (See section 6.7.5 “Roll
Paper Cutting Mechanism.”)
! The rollers in the fusing unit [9] feed the sheet to the exit rollers [10].
! The exit sensor [11] checks that the leading and trailing edges of the sheet go by at the
correct time.
! The exit rollers feed the sheet to the paper junction gate [12].
! The paper junction gate sends the paper to the upper exit rollers [13] or sends it out the
rear [14] of the machine. (see section 6.10.2 “Switching the Paper Exit.”)
