Silver Seiko Automatic Paper Folder MA150

This is a listing for a Silver Seiko MA150 automatic paper folding machine.

The power has been turned on and the motor operation has been confirmed.
I believe it is running smoothly with no unusual noises.
As seen in images 2 and 3, there are scuff marks (cracks).
The unit is discolored overall. (Please judge from the images.)
I have wiped down the product, but I do not believe all dust and dirt have been removed from the details.

When I inserted paper and ran it through, it left marks on the center roller, suggesting that maintenance and replacement of consumables may be necessary.
I only ran paper through it; I have not confirmed its folding functionality.

This is a used item purchased about 10 years ago. However, it is not suitable for coated paper, the operation is completely unclear even with the manual, and consumables need to be replaced. Due to these issues, it has been stored without use.
