printed shorter than original image

[popurri]

Hi
I have riso rp3700 machine.
When master is making, A long side of paper (420mm side of A3) is little shortened than original image.
So to print accurate size, I have to increase the the length of the image by 102%.
It's very annoying.
Is there any simpler way?

Are you sure of:

right size being sent to master?
right size master?
have you reset machine?
had an error show?
anything blocking size sensors?
paper trays defined properly?
right paper loaded?

The rubber write roller has shrunk a bit due to age/use. Adjust TM 287 (Master Making Speed Adj) to a slightly more positive (+) value.
