Sorry...... you'll have to wait. Designed that way to prevent drum damage.

Didn't you get a "Toner Low" warning message before the printer stopped?

Thanks for the verification.  I did receive the "Toner Low" message well in advance, but when I installed the "new" catridge I had, I discovered that it was an old one that was never returned.  My bad.  I'd just like to print in B/W while I'm waiting.
