SOURCE: need to reset password for verifone omni 3740

If you press the F2 and F4 buttons and enter 1 Alpha Alpha 66831 and the terminal goes back to the idle screen then the system password has been changed or the battery is bad in the unit and will have to be replaced. Either way it will have to go to a repair facility to be corrected.

Screen goes blank at start up


Its failing to go through the full boot process. Try pressing F8 on boot until the boot option screen comes up and then select safe mode. Follow this though until you are given the option of using system restore instead of safe mode. take that option by clicking on the NO button. Restore the machine to a date some time a few days previous to the fault developing.

If that fails then put in any OS disc and boot from it. select R at the first options screen, follow it through and then select the C drive option. Just hit enter when asked for admin password.

now type chkdsk /r (copy and paste this to be sure). let it run and then reboot and see what happens

We found that it was neither the thermal paper roll nor the thermal component. The cover did not close tight enough and that caused the print-put to be light or missing printed areas.
