Paper jam on QSS-3301 (Size 8" wide & 13" long or longer)

[davidlam]

Dear all, we have 8" x 13" paper jam problem on QSS-3301 printer side. We use 8" wide paper and when paper advance is set to 13" long or above, the leading edge of the paper will stop at the inlet roller of the exposure advance unit   and then    the paper jam error occurs.... resulting also that we cannot do the "emlusion no. change" calibraiton since that strip will be 8" wide and 13" long (got jammed), a TRUE paper jam

When the paper advance length is set back to 12", it is NO "paper jam" problem at all.

Moreover, we have NO problem found on other paper width of size photos also, e.g. 5" x 13" long, 5" x 14" long, 6" x 13" long   and    6" x 14" long print size

please help to advise what could be the problems of  [ 8" x 13" long ] or longer will result  TRUE paper jam .   Thanks.
