If it's a timer or clock, you could always add a light or note block to the output line of the pressure plate that would turn off when nothing is sitting on it
It can be done but you would need to add a counter that would need to be triggered each time you fired the dispenser. If your dealing with small stacks of 16, it shouldn't be too hard, but if your dealing with items of the 64 stack then the counter is gona require quite a bit to setup. A piston array here will probably do, but will require quite a bit of space to setup.Was thinking also you could if its an item/mob your dispensing, have it dispense onto a pressure plate, then check the input after the dispenser has been fired, if nothing shows obviously the dispenser is empty.
If hes using a pressure plate, then its easiest to...
The button or trigger that fires the dispenser just needs to split itself, going into a series of repeaters, set to max delay, half dozen should be fine set to max delay. Meanwhile the dispenser fires and the item/mob hits the pressure plate triggering a nor-latch.
Once the split signal finishes, all he has to do is check the latch, if its been triggered the dispenser fired, (release the latch), and ready for next fire. Otherwise, he can signal whatever he wants to notify that the dispenser is empty.
If hes not using a pressure plate he has no choice but to use a counter. The arn't hard to setup, they just take quite a bit of space.
Another solution may be to use the bucket of water as the last item your dispenser spits out and set it up so that the water flow triggers a BUD switch connected to your "empty alarm".

I recently had an idea to do with redstone. It is as follows.
A system which outputs a redstone signal when a dispenser is empty. I'm sure there is some way of doing this.
Please help.
Thank you.
He's right, the only thing is that clicking sound when a dispenser is empty and you activate it
5 mins after the fact, as thats how long item entities stay on the ground before despawning.
