hp laserjet 2500 print again at blinking toner

Archived from groups: comp.periphs.printers (More info?)

hi all,

does anyone know how to print again if the printer says by the
blinking light the toner or the drum is empty? I can't believe that
the toner cartridge or the drum kit doesn't work again for a while!
the toner and the drum kit is to expensive to dump it before the print
quality is poor.

thanks in advance
