Your Samsung ML-3561ND looks to be an HP Laserjet 4000-series printer. Same engine, different electronic. The fuser is in the rear of the machine, and may be relating to the drop-down rear panel where you clear paper jams. Open it and give it a good push closed and the printer should cycle and come ready. Let me know what happens!
The fuser door is a metal flap under the toner cartridge (so accessed via the top cover) with a green tag on the right hand side - at this position there are two contacts. If just making sure the fuser door is fully down fixes things - that's good; otherwise there may be an issue with the sensor components.
