You may need to call your Dealer for on-site support and trouble-shooting, however, I can give you a couple of suggestions here first.

My first guess would be that there is something wrong in your specification. To determine this, you could try using a sample spec from samdata, to see if it prints ok with your data. If it prints fine, then you need to modify your spec.

If you get the same results, then you should do a Data Integrity Check as you may have some corrupted data files that are causing this problem.

There is a sample cheque (QC$SAM3.SAM) spec in our sample data that is advice-cheque-advice. You should use that as your test spec.

Hope this helps.
