If you're using Mac OSX 10.6 (Snow Leopard) then make sure you've downloaded the Samsung printer update (click on the apple in the upper left corner and select Software Update). There is a known issue with the same symptoms you have, and the update should fix it.
If you're on Windows, then there is no known issue, so it could be any number of causes. My first suggestion would be to delete the printer and reinstall the latest drivers from www.samsung.com. If the problem persists, try changing the Power Save timeout (either from Smart Panel or using the SyncThru web interface) and see if it still has problems waking up with shorter sleep timeout.
I'm being offered an ex display Product code: ML-NWA10L for my 3051nd I can't see an antena, this seams strange for a wireless item, what do you know please? do you have any usefull downloads I could have please?
Connecting ML-3051ND and Win7-64bit with Universal Print Driver (ver.2.02.05.00:25)
The Win7 Network desktop icon sees to printer on the network, and clicking on it shows all the printers settings using SyncThru. But when I run Samsung_Universal_Print_Driver.exe, it cannot find the printer.
Print is not as dark as I would like. Is there a new print driver available that would help?
I just installed a new Samsung toner cartridge in the machine today and the pages are not coming out as dark as I like...very difficult for me to read at my age (75). I have the "Toner Save" turned off (always), otherwise the pages have always been too light.
Is there some way of determining the number of pages already printed, either from the very beginning when the printer was first used or the number of pages printed since the current toner was first installed?
