Hi everyone hoppe you can she dsome light on this. we have an agfa dlab 2 which was fine for the first 18months or so then all of a sudden our whites seem to be off like a cream/yellow ive dumped the chemistry 1 by one and narrowed it down to the dev but when we put new dev in the whites are perfect but within a week or 2 they start going off again any ideas what this could be? people have said it could be low utilization but im not so sure. Thank you
