Question about Honeywell Metrologic (E64392) VoyagerCG MS9540 Barcode Scanner Handheld Barcode Scanner

1 Answer

How do you change the button / trigger in MS9540? I have problem that the trigger in MS9540 sometimes works fine, and some need to press really hard to make it work. The scanner and mainboard seems fine since when it works, data transmission and reading is not affected. And is the button the same on all MS9540 interface (USB, PS2 and serial)? Many thanks,.. Aaron

How do you fix a jammed trigger on the Ryobi 10 Amp Electric Power head

Not really a fix but it worked for me. I opened up the case. Their is a little black box with a red button that must be depressed. Pulling up on the trigger pushes the button. Their is what i call a counter press above the trigger. By pressing it, it makes room for the trigger to slide up and press the red button. There isn't much you can do improve this process. But i took the two springs off the trigger and depressed them trying to shorten them thus reducing the force needed to press. The counter press in spring load. I carefully stretch it by pulling on the end directly above the trigger(not against the frame). This took some pressure off the counter press. I finally took a small file and carefully filed down the edge of the counter press where the trigger presses against. This makes it slide upward easier even if the counter press isn't pressed down fully when you squeeze it. The trick is pressing the counter press first, but doing these things has made my trigger a lot smoother. It use to be a hard press to activate, but now it is 10 times better than it use to be. Good Luck!!

Kenmore elite HE31 front loader will not start but has power

This seems to be a problem in the start switch diode. If all works fine, but will not push and start and all cycles seem to work when working it manually, this is in the switch timer electronic diode is not working properly. Sometimes a code will not come up, because cycles are still working when manually changing wash cycles. There is seperate switch or electronic trigger that starts the machine, and has probably worn out or not making good contact. If you can unplug machine and then take off panel, trying spraying behind start switch with electronic cleaner to free up any possible dust or dirt. Might get lucky.

Dispenser not dispensing water when we press the button inside the refrigerator. It was fine this morning. Just suddenly stopped working. Hoses all still connected.

Seam than you either have a bad water valve or you water line has froze up Disconnect the water line going out of the water valve but live the one going in still connected and whit pressure and fridge plug up. have some towels handy, Ask a helper to press the water trigger if water squirt out of the valve when the trigger is press That means than the water line has froze up and you have bad thermostat and is letting get to cold on the fridge side. Id you don?t get water to come out test if you are getting power to the valve when triggered if you do get around 120volts then change the water valve

The Right Trigger isn't working at all

I had a similar problem with my left triger but cross731 had said to lift up the triger with your finger nail, and blow into the hole. This supposedly gets rid of dust. Now if you have damaged it by dropping it several times than.. I recremend that you take it in to be fixed.

Nintendo DS Lite, left trigger not functioning

The thing that cross731 said really really helps. If your too scared to open your ds/ds lite, just put your nail under the trigger pull up and just blow into the little hole that you see. It works I just tried it and my left rigger is working just fine.

Voyager MS9540 freeze problem...

Unplug your scanner first, then run your excel, type some code which used to scanned by your scanner as quick as you can, if your computer doesn't hang (freeze) then try to entering setup of your BIOS, find some type matic rate, change it to higher value, i think your type matic rate were set too low. If it's not solved please let me know
