Hi Chris,
Thank you for using the Support Forum. the minimum booklet size for the Plockmatic Pro 35 is Min: 8.1 x 5.4 in. (206 x 137.5 mm). Please see the brochure for additional specifications.
Can someone tell me what is the smallest book size that you can run and trim down the ploclmatic? I have tried to search and have had no success on this.
