Frequently Asked Questions - WT22M-FB AOPEN
How do I load receipt paper into the printer?
Open the printer cover, place a new 80mm thermal roll with the paper unwinding from the bottom, pull a short length out, and close the cover. The printer will auto-feed.
The display shows 'No Paper' even though there is paper. What should I do?
Check that the paper roll is properly installed and the printer sensor lever is not stuck. Remove and reinsert the paper, ensuring the edge is straight.
How can I set the date and time?
Press the [SET] key, enter manager password (default 123456), navigate to 'Date/Time' using [↑][↓], and use numeric keys to input current date and time. Press [ENTER] to save.
My cash register does not turn on. What can I check?
First, ensure the power cord is firmly connected to the register and a working outlet. Check the power switch on the back. If still off, try a different outlet. If none work, contact support.
Can I connect a barcode scanner to this register?
Yes, you can connect a USB or RS-232 barcode scanner. Plug the scanner into the corresponding port and configure the scanner interface (usually USB HID or serial). The register will read barcodes automatically.
How do I reset the manager password if I forgot it?
You cannot recover a forgotten password. However, you can reset the machine to factory defaults by pressing [CLR]+[TOTAL] during power-on. This clears all programming including password.
How often should I clean the thermal print head?
Clean the print head every 3 months or after heavy use. Use a thermal head cleaning pen or a lint-free cloth with isopropyl alcohol, gently wiping the head. Allow to dry before use.
My receipts are printing too light or missing lines. What's wrong?
This usually indicates a dirty or worn print head. Clean the head with a cleaning pen. If problem persists, the head may need replacement. Also, ensure you are using high-quality thermal paper.
How do I program a new PLU (price look-up)?
Press [MODE] until 'P' appears, enter password, select 'PLU', enter a PLU number, then enter description and price using numeric keys. Press [ENTER] to confirm each step. Finally, press [MODE] to exit.
The cash drawer does not open when I press the key. What should I check?
Verify the cable connecting the register to the drawer is securely plugged into the RJ-12 drawer port. Test the drawer separately with a 12V source. If it opens, the register output may be faulty. Check also if the drawer lock is in 'OPEN' position.
