We are cleaning up a newly acquired UNI IIIP, and have noticed something which is disturbing.
Under the register rack (X-2831), is a shim that looks approximately 2pts thick and resides nearest the feed table. A smaller shim is at the end nearest the floating rack.
We are assuming that these have been put in place to solve a problem. Can anyone shed some light as to what is most likely wrong and what the implications are?
Are the shims in place for the reasons mentioned in this post?
