Many customers don't know how to use it after buying the attendance machine, or they have some problems in the process of using the fingerprint attendance machine. I don't know how to solve it. Now I will list some common problems in the process of using the attendance system. I hope that I can play some tricks. The role.
1. Can the attendance machine not communicate with the computer?
A: First check if the COM port and network port are connected, then check the attendance machine settings: press “MENU†in “Settings†→ “System Settingsâ€
View the machine number of the attendance machine (default is 1), baud rate (default 38400). View computer and software settings: wave of computer COM1 port
Rate (default 38400), software settings are detailed in the software help.
2. What is the reason for the "voice" sound when the attendance machine is connected?
Answer: 1 If the above phenomenon occurs when using RS-232 communication, the baud rate of the computer is inconsistent with the baud rate setting of the attendance machine.
2 If RS-485 communication is used, it may be that the two wires of the converter communication line are reversed, or the two wires are stuck together.
3. After the attendance machine is turned on, it will repeatedly display "Please press (leave) the finger". What is the problem? How to solve it?
A: The reasons for this problem may be:
1 After using for a long time, the surface of the collecting head becomes unclean or scratched, which may cause the collecting head to mistakenly believe that the surface has a finger and cannot pass.
So this problem occurs. In this case, you can use a self-adhesive tape to paste the dirt on the surface of the collection head.
2 The connection of the fingerprint collection head is loose or loose.
3 motherboard chip is broken.
If there are two reasons for items 2 and 3, you need to contact the supplier to apply for warranty.
4, some users fingerprint attendance often can not be verified, how to solve this problem?
A: Some of the following situations may cause some employees to use or not use fingerprints for attendance:
1 fingerprints are smoothed on some fingers;
2 There are too many folds on the fingers, which often change;
3 finger peeling is serious;
A user whose fingerprint is not recognized can delete the fingerprint and re-register it, or register another finger.
When registering fingerprints, such users need to choose to use better quality fingerprints (less wrinkles, no skin, clear fingerprints), try to make fingers
Contact fingerprint collection head area is larger, do a comparison test after registration is completed; and it is recommended to register a few backup fingers.
