Check joggers Shear tech MJ-1000 mini jogger is a small, table-top, automatic. The importance of check joggers in check processing centers has been known for many years. You can find a check jogger near almost every high speed reader/sorter. There is a perfect reason for that. Jogging a batch of checks for a few seconds in the check jogger, perfectly aligns bottom and side edges of checks which reduces chances of check jamming and double-feeding. We designed our shear tech MJ-1000 Check Jogger specifically for smaller banks, branches, community banks, and credit unions, with lower volume of checks.
