  • Precautions

    Before proceeding, there are additional steps to avoid error message from the printer:

    • Label empty - When label roll finishes, the LED light will blinking in red indicating you to change the label. Replace with a new label.

    • Label size (wrong setting) - When prompted to print, the LED light blink in red indicating the size set on PC does not match the actual size of the label. Make sure label size are setup correctly in the PC software. Additionally, select the correct sensor type for the printing too.

    • Label guide - If you have multiple size label, make sure to adjust the label guide every time you load the label. The guide aligns the label to the centre so the printer prints the same position for subsequent labels. If the guide is too loose or tight, the printing will misalign and prompts paper jam error. Additionally, it goes without saying that the label sticker should be facing upward. You should also make sure that the label width does not exceed its maximum capacity. If you have wider label, you may opt from our variety of printer model to suit for application.

    • Ribbon - Error maybe prompted due to issue with the ribbon. When ribbon is empty, the red blinking error will be prompted. If this is not the case, the ribbon may have been torn. Reroll the ribbon or replace ribbon when necessary. Do make sure the ribbon ink is facing out and the ribbon core are installed correctly onto the printer.

    • Ribbon ink facing out - When you are loading the ribbon, make sure the ink are on the outside. You may have some leftover barcode ribbon lying around. You think that it would be wise not to waste. However, not all barcode ribbon ink wound the same. Before loading the ribbon, make sure the ink are on the outside. A good way to test it is to paste a sticker to the ink surface. You are able to identify which surface the ink is coated based on where the black ink sticks to.
