I have a 1320c laser printer and have been very pleased with it since the day I got it - though I didn't know the PHD would need replacement. Now 6 months later, I've almost hit 20,000 copies and the little exclamation point has blinked on.
My question is, how soon must I replace the PHD? . . . it still seems to be printing fine (especially if I do an occasional refresh).
I have a replacement, so that is not a problem . . . I just want to get as much life out of the existing one as I can . . . sort of like the toner cartridges - the replace light goes on but I wait until the error msg comes saying "replace now" - will something like this also happen with the PHD?
The only notation I can find on the Comsumables is that the "Expected Replacement Cycle" for DT574 PHD unit is 20,000 pages. I would use it until you start seeing diminshed printing.
