mxm363n creasing a3 only

i have an mxm363n that is creasing pretty much down the middle of the sheet. sometimes crunches the paer completely.

the fuser was refurbished 4 weeks ago and the pressure rllr is still in good condition.

the image is visible inside the creases and rubs off

the fuser entrance and exit guide are clean.

the a3 paper has been replaced with fresh paper and tried and tested from different trays.

a4 is completely in working order with no creases at all.

sometimes th a3 jams at the fusing entrance guide as in the paper isnt being guided pproperly into the fuser. fuser turns by hand nice and well.

i tried adjusting the fusing entrance guide many times at different setting and sometimes the jammming gets worse.


can anyone help me please
