I along with my previous Professor had submitted a journal article to an IEEE Transaction. It got accepted now while I no longer work with him. Our accepted article has a page length 15 and the Mandatory Overlength Page Charge is 220$ after 8 pages. Due to funding issue, my previous Professor would only be able to pay for 3 extra pages at max. Would it be helpful if I write a mail to the concerned journal's Editor explaining my problem? Has any student got such waiver in the past?
