When switched on, my Samsung ML1510 mono Laser Printer starts up with the usual whirring noise and up to now, this has lasted only a few seconds, then it goes quiet until a document is sent for printing, when it starts churning away, then produces the printed document. However, it has just developed a fault in that it does not 'settle down', i.e. the initial whirring noise just keeps going on and on. Can anyone please advise a solution that does not involve opening up the printer, as I have only limited technical knowledge. Thank you.
Laser printer's generate heat and the whirring noise is usually the fan. It is possible that the fan is switching on and then failing to stop or it needs to keep running as the printer is too hot. You need to also check that no foreign object has got left behind (perhaps a bit of paper) and that the paper path is completely clear.
