Accounts Payable Check Printing

We had 2 checks stick together during check printing.  I did not notice we were off by a check number until I had printed and posted the batch.  about 40 of our 78 checks printed are off by 1 number.  How do I fix this?  Do I have to void them all and reprint??  Is there a way to simply change the check number attached to these 40-ish invoices?  Even if it's one by one would be better than voiding and reissuing them.  Thanks in advance
