Replace 3 inked cylinders with 3 spacer cylinders to print all digits.
Which cylinders are they?

To print, gently press the 2x1 paper sides and middle on
1x1x2 assembly touching 7 cylinders in any positions..

PRESS 1X2 PAPER FOR:

0 TOP & UPPER RIGHT

9 UPPER BACK TO TOP

8 LOWER & UPPER BACK

7 LOWER & UPPER LEFT

6 UPPER BACK & LEFT*

5 UPPER RIGHT & FRONT

4 LOWER TO UPPER RIGHT*

3 UPPER LEFT & FRONT

2 UPPER FRONT & RIGHT*

1 BOTTOM & LOWER LEFT*

I have thought about this, and I conclude that I don't get it.

I'm seeing this as an inked stamp.

Wouldn't you have to replace some spacers with inked ones?

Can you touch the paper twice ... ?

You can make your own combination of red (inked) or silver (spacer) if there are other cylinders available. Let's allow that. But could worsen the task.
Hinted above ,12 reds and 8 silvers is all that can do.. For printing, imagine the 1x2 paper unrolls lengthwise continuously to touch 7 cylinders in any direction..

That explains it, kink of like a rolling action. Thanks.
