Q: Some users’ fingerprints often cannot be verified. How can this problem be solved?
A: The following situations could result in verification failure:
(1) The fingerprint was rubbed down;
(2) There are crinkles on the finger which often varies;
(3) Serious desquamation on the finger.
If a user’s fingerprint is not able to be verified, please delete it and then enrol again, or use another finger for enrolment instead. Select an untarnished fingerprint (less crinkle, no desquamation, clear image) when enrolling the fingerprint, allow the finger to touch the sensor knob with a larger area. A comparative test should be done after enrolment, and it is suggested to enrol more fingerprints. The Fingerprint A11 supplies a 1:1 comparative method and password attendance function to check employees’ attendance.
Q: Which aspects cause Fingerprint A11 terminal communication failure?
A: The following situations could result in communication failure:
(1) Wrong COM setting, COM selected to connect is not the COM port actually used;
(2) Baud rate setting between computer COM and Fingerprint A11 differs;
(3) Fingerprint A11 is not connected to power or computer.
(4) Fingerprint A11 is already connected, but the power is off.
(5) Incorrectly connected Fingerprint A11 terminal.
(6) Data wire or converter cannot communicate.
(7) Faulty COM on computer.
Q: LCD cannot fully display after switch on, sometimes a strip occurs on the screen, how does one solve this problem?
A: There are two potential problems:
(1) The main board is faulty;
(2) Internal characteristic problem on LCD, contact the supplier and return the terminals to be repaired.
Q: How does one eliminate the administrator on the Fingerprint A11 terminal?
A: Fingerprint A11 and computer communication are available to use, enter into manage label page, click cancel administrator button, then eliminate it. After the connection halts, time and attendance menu mode occurs.
Q: Why does the Fingerprint A11 terminal give a faulty sound signal after the communication system connects?
A: Computer baud rate disaccords to Fingerprint A11 baud rate setting, which results in the abovementioned phenomenon, if using RS-232.
If using RS-485, either the two converter communication wire is connected oppositely or is sticking together.
Q: On turning on the Fingerprint A11 terminal, the terminal displays “re-press/ (remove) fingerprint” time after time. How does one solve this problem?
A: Possible reasons:
(1) Extended period of usage, surface of sensor knob is unclean, or has a scratch on it, which was mistaken by the sensor as a finger, but was not verified, causing the above problem to occur. Under these conditions one can use an adhesive to reduce the dirt.
(2) Connection wire of sensor knob is loose.
(3) Chip on board the Fingerprint A11 is faulty.
Contact supplier for guarantee if problems ② or ③occurred.
Q: When reading the attendance record, it shows failure or mistake halfway through the record, although it is fine while downloading the fingerprint and password for the manager operating the Fingerprint A11 terminal. How does one solve this problem?
A: Such situations are possibly related to data wire, converter, or COM, which decrease the baud rate between computer and the Fingerprint A11 terminal. Set 19 200 or 9 600, then read and write.
Q: What is the problem if there is no sound from the Fingerprint A11 terminal?
A: The speaker or the voice chip could be faulty.
Q: When switching on the Fingerprint A11 terminal, the start-up bar cycles, but the terminal cannot enter into the time and attendance interface. How does one solve this problem?
A: Check the Fingerprint A11 knob wire to see whether it is correctly inserted, or faulty. Should the knob wire be inserted correctly and in working condition and the problem persists, contact the supplier.
Q: The time on the Fingerprint A11 terminal is sometimes slower. How does one solve this problem?
A: If the Fingerprint A11 terminal is several minutes slower in one week, the clock crystal could be faulty.
Q: The Fingerprint A11 terminal shuts down and the clock shows the wrong time after rebooting. How does one solve this problem?
A: The MCU may be faulty, contact the supplier.
Q: The Fingerprint A11 terminal displays the time as”00:00” a few minutes after rebooting, why?
A: The battery in the clock may be faulty, contact the supplier.
Q: The sensor light on the Fingerprint A11 terminal is not luminescent, why?
A: Your fingerprint is similar to another person’s, which caused a false time and attendance acceptance. Choose other fingers instead.
Q: Why is there no sound when the “press” key is pushed or no sound from the Fingerprint A11 terminal?
A: It could be a faulty buzzer, speaker or circuit. Contact the supplier.
