Olivetti Logos 9.

[flaviosr]

Dear All,

I know the Olivetti Logos 9 is not a computer... but it's a very special calculator! :D the smallest one with an integrated printer...
I try to post here my issue... if anybody can help!
My (almost near zero) technical skills are stuck!

I have found a very beautiful one.
I have removed the battery and created a small circuit to simulate the internal double voltage.
I have cleaned all the PCB keys so that they now all work.
The printer is moving but it's not printing anything.
The roller is clean.

Can anybody help...?

Thank you

Has the ink ribbon (does it have an ink ribbon?) dried up?

Have you asked the folks at the OldCalculatorForum?

Thank you! I was not aware about this other group only for calculators...

mmm... I supposed it was a thermal printer but now I notice that paper "seems normal". For example the paper is not like the ZX Printer...
Now I think it is a ink printer but I have not doc about it!
