Feed and Tear Off position problem

I am printing multi-part Bill Of Lading forms on a ML320 Turbo. The application is an older DOS application that prints directly to the printer rather than using a Windows printer driver. It feeds the correct number of lines to match the form's 8.75" form length. Until a couple of days ago the form would print and then stop after the last blank line. Tear Off is set to OFF so the shipping people would press the Tear Off button to feed the form to the perforation and then press the Tear Off button again to return to the Top of Form.

I don't know if someone accidentally changed a setting or something but now the printer feeds after printing as if the form were 11" in length. The perforation is above the tear Off position even before hitting the Tear Off button by about 1/2". Unless the form is manually returned to the Top of Form position before printing additional forms, they will be mispositioned.

I have tried everything I can think of to return this printer to the way it operated previously with no luck.

Any suggestions?

Thanks,
