Excessive Jamming of Cardstock in C6501

[Setright]

Tex has it. I expect that a normal sporadic jam occured and during recovery the card stock was pulled out and bent the plate upward. This leads to the consistent jamming you are experiencing now.


Card stock is defined by weight, but we should really create a stiffness index for it too. One 160gram paper might be stiffer than another brand/type in 250grams.

The double LCT, cassette 4&5, will doubtless make your life much easier, but stiff cardstock will always jam more often than paper.

I stand to be corrected, but I am sure that these rollers are not even used when paper is fed from the bypass.

The person that is complaining that putting too much weight on the bypass roller will not allow the ADU to open:

Dudley mentioned correctly if additional weights are used 'You may have to adjust the spring pressure that is used to raise the feed roller back up(its the screw in the slotted hole to the rear of the tire assembly)'
