How to Reduce From Legal Size to Letter Size on a Copy Machine. The reduction feature on photocopy machines is a handy tool for quickly making a document smaller. By reducing a legal-size page to letter-size, the document can be copied using normal copy paper, eliminating the need to purchase a separate package of legal-size paper. In addition, letter-size paper will fit more easily into binders and folders.
Raise the copier lid.
Place the original face down on the copier glass.
Check the paper source to ensure that the paper is oriented correctly.
