printer toner warm-up question

[rh71]

I have a Samsung all-in-one monochrome laser printer and it came with the starter toner (only did a hundred pages if that). It only warmed up (loud noise) for like 5-10 seconds and was ready to print. I finished that toner and got a full replacement off-brand toner. Now it takes almost 2 full minutes of warm-up time. Is this just because there's a lot more toner to warm up? Meaning this is to be expected? Or possibly because it's not genuine toner?

I doubt that would matter. When the printer is warming up it is not the toner it is heating, it is the fuser. The fuser is a pair or rollers in the printer that heats up to liquefy the toner after it is sprayed on the page.

I can't imagine how any "toner" (only) cartridge could have any bearing on warm-up time, since as SMOGZINN notes, that's not what's being heated, but - speculating wildly - if the "toner" cartridge is really a combined toner-drum unit, maybe that could (somehow) have some bearing on the warm- up time? On the other hand, are you sure it's really taking that much longer to warm up on a regular basis, or is it possible you started paying closer attention after replacing the cartridge and maybe having lurking suspicions that the off-brand replacement might not be as good as the OEM one?

The aftermarket toner probably gunk up the thermistor on the fuser assembly?
The aftermarket toner is screwing up the readings on the toner density sensor?
The aftermarket toner is screwing up the readings on the toner capacitance?
List goes on and on, but yes, that can happen.
