Paper tear, J430X/431X/440X/471X, Horizontal line at 60mm
from bottom edge
（
Phenomenon1
）
If the leading edge of the actuator switching the switchback sensor is hooked with the center hole of 3-hole pre-punched
paper when the paper is turned over with the duplex printing, the paper may be torn or the paper jam
(J430X/431X/440X/471X) may occur depending on paper thickness.
(If the paper is torn, the following phenomenon 2 may occur at the same time.)

Check the Firmware version and version up to above FW PACK V4.00.
1. During usage of a pre-punch paper with 3 holes, if paper tear/JAM and horizontal line at 60mm from bottom edge occur, please take the following
measure.
[Restriction when using 3-hole pre-punched paper]
Please keep and perform the following restrictions when using 3-hole pre-punched paper even if performing
the corrective measures.
1.The length of the punched hole in the paper feeding direction on 3-hole pre-punched paper must be 8mm or
less.

If the punching hole is longer than 8mm in lengthwise, the leading edge of the actuator switching the
switchback sensor falls down the center hole of the paper when turning over the paper in duplex
printing and as the result, the punched hole may be torn or the paper jam may occur.
(Phenomenon 1: Tear/jam of the paper at the switchback section)
2.The distance between the hole of 3-hole pre-punched paper and the paper rear end must be 15mm or less.

If the punched hole is farther than 15mm from the paper rear end, the interval to the next fed paper
becomes short and then the regist drive stops though the paper doesn’t pass through yet. As the result,
the horizontal line appears on the image. (Phenomenon 2: Horizontal line on the image of the paper rear
side.)
3.Don’t eject 3-hole pre-punched paper to the JS-731 (right job separator).

The JAM 470x/471x may occur due to chattering of the fuser eject sensor if trying to eject 3-hole pre-
punched paper to the JS-731.
