Question about Mustek (MUSTEKUPS600) UPS System

1 Answer

Powermust 600 Plus doesn't provide power

When I turn it on, Led does not light, there is a permanent sound coming from device, and there is no electrical power provided from the unit. All of it is being happened while the unit is connected to an electrical power source. When it should provide power by it's own battery, nothing happens.

You might check your device manager to see if there are any clues there before trying a new battery. Also, check your Power Options settings and see if there is a conflict.

LED light doesn't light up on JL Audio XD 600/1

It could simply be a faulty or burnt out bulb, just find a small bulb at Ace Hardware or the similar, and replace it.

My numeric 600 plus ups swithched off automatiocally when power goes off not a single second back up its provided

Did it work before?

If so, then it has developed a fault. Check the battery fault light on the UPS panel. Perhaps it's battery is dead, or batery charging circuitry is faulty. Anyway, it would most probably need professional attention by a serviceperson.

If it did not, double check whether you have connected the computer etc. to the proper sockets - many UPS devices have a couple of UPS-powered sockets plus additional sockets with surge protection only (no UPS power!) for high power devices like laser printers etc.

Please come back and leave a rating/testimonial if helped or post a comment for further assistance.

Did you read the manual for your UPS ?
I read it - there was something about lamp ledding - different ledding of lamps and different frequncy of noisy sound can mean different problems - try read manual.
I think, your description means that you need to change battery.

Hi there, I have an american DJ Dekker LED. I plugged it in and put it into Sound active / sound to light mode. I'm getting response to sound because I can hear and see the fan inside the unit...

I have OFTEN found that a cable has come loose. Open the unit and look for such a situation. Also make sure the motion (probably a disc) is working/rotating since with high power LED devices, they have interlocks for safety to keep beams moving.

Waste ink absorber is full. how to clear this

Canon recommend that you need to bring the printer to your local service provider, canon will not provide Joe Public with the replacement parts as consumables and even more importantly they will not provide the software to reset the error message.

From what I can see there is a hardware routine type fix for the problem,

1. Unplug power and USB.
2. Open door and hold power button.
3. Connect power.
4. Close door, then release power button.

1. Turn off the printer. And disconnect the printer cable.
2. Press and HOLD the POWER button, turn on the printer.
3. The indicator (L.E.D.) should be green.
4. Press and release the RESUME button, the indicator (L.E.D.) should be orange.
5. Press and release the RESUME button again, the indicator (L.E.D.) should be green.
6. Release both buttons.
If this hardware routine type fix works it is at best merely a temporary fix, and needs to be repeated on a regular basis to keep the printers running. For a more permanent solution you need to combine the fix with the more complicated task of removing the pads and cleaning them. This is where the whole process can go disastrously wrong, the ink is permanent and will stain hands, clothes and furniture if it comes into contact with them. Check out the info on this website and on your own head be it

There are a number of websites which claim to provide the software fixes however using these is a kin to sailing in uncharted waters, it is your own choice however I would be hesitant to recommend it to anyone especially if there are a few government secrets on your hard disk

My advice is to find out how much your local service center will charge you to replace the ink absorber, then decide whether it is worth the expense. And when it comes time to change the printer remember canon's have ink absorbers which need to be changed by a service engineer

For more discussion on this problem (and many of the hard ware fixes plus a few links to the software reset providers) see the forums on

Compaq Presario SR1315CL will not power on. Green LED on power supply flashing.

I have the same pc as you and i have suffered the same problem. If all the lights come on and the hdd light flashes and the fan sounds loud, then turn off the system, disconnect all the leads, give it a bit of a clean inside (not necessary but helps) and reconnect the leads and you should have power! This is not permanent mainly for backup purposes
