Gun won't shut down - Symbol MC9090-G Barcode Scanner

Strange how this is posted in Problems with cell phones. I guess if you don't know where to post your question, then you should not won a gun

You shouldn't remove the auto shut off feature, it is a safety mechanism, and it will increase the life of the gun. It is also very convenient because you won't put the gun down and come back to find it in a pile of melted or hardened glue

As a safety precaution, nailers have incorporated a safety foot that will prevent the gun from firing unless you push down hard. Some guns also have a system where the gun will not fire at all if there are no nails in the gun. To dry fire this type of gun you must pull back the pusher or open the side door. If nails do not feed properly, check for wrong nails, bent rails or weak pusher spring. If all is good with rails and pusher, suspect that the driver/piston is not at top of cylinder and lower part of driver blade is preventing nails from advancing. Remove airline and push the driver to top and retest. If driver is slipping down the cylinder under its own weight, replace oring. Good luck

replace circuit mold assembly or spark unit its probably the spark unit

unplug it

I am thinking that perhaps the temperature sensor is reading wrong and therefore sending a message to the computer that the car is running too hot. This can happen, my VW presently reads 20 hotter on the guage than a heat gun records at the temp sensor location on the head. If you have access to a heat gun it might be a good idea to check out the actual temperature, but it probably won't hurt to change the sensor.

The other problem that occurs to me is the oil sending sensor. While a temperature sensor won't shut an engine down, the oil sender can. If it is reading a large drop in oil pressure it will shut the engine off. Since oil gets thinner as it gets hot, perhaps a defective sending unit is reading it as too low. Once the oil cools off, it would restart until the temperature gets too high again. I would think that upgrading to a heavier oil might cure the problem. I don't know what you are currently usung but certainly you could go to 10W30 or 10W40 without too much trouble, at least for a test. Hope this helps.

Hold down the power button for 10 seconds. That will hard-shut the PC. Once that is done, fire it back up, and try again. Somethimes, windows will act goofy shutting down. Especially Vista when it is left on too long without shutting it down.

Try cleaning the glue stick slot out with acetone (nail polish remover) and a paper towel, or cue tips if you have to get into a small area. that should help to break down any dried glue that may be blocking a new stick from feeding in, or may be blocking the heating element

Hello,

There is a glue build up inside. Most likely in the feeding mechanism, try to heat it up, the unplug, and use like a paper rolled up to try to remove some of the glue. :)

Make sure the staples you are using are compatable with your gun they should be type 53 or JT21 staples and they are not longer tham the gun is capable of taking I think the maximum capacity for this gun is 5/16 or 8mm.
Turn the gun upside down and pull back the carriage, the staples are laid in the empty chamber in the gun itself not on the carriage points facing in the direction they fire ie points facing you .
Push back the carriage this should slide over the strip of staples until the carriage clicks shut.
You should now be ready to fire, try and keep pressure down on the gun as the recoil can make the gun bounce and you will leave the staples proud.
Hope this helps.
