Jam when using B5 paper size

[aaahmmm]

I have jam in B1 , B2 area ( registration ) of aficio 1060 when changing to B5 ( 17.5 mmx 25 mm) paper size , I check all the tray settings.

Note: no jam when using A4 size

That would be 17.5 CM x 25 CM !

Are you feeding SEF or LEF?

LEF feed

(without checking the spec) I think the mchine only runs B5 SEF (?)
