Why is the printer printing blank labels?

The three main causes of this problem are as follows:
1) The most common reason is that the labels were loaded upside down. Please ensure your labels are properly loaded that tearable side should be facing the ceiling when it comes out of OFFNOVA.

2) Label issues: Please ensure your labels are "Direct Thermal" labels and the paper enclosed in the package meets this condition.

3) The printer has not identify your label's properties. Please follow the steps below to fix the problem:
a. Switch off the printer and restart.
b. Open its cover and reload thermal labels, close cover.
c. Press and hold the green feeder button until the printer beeps one time to identify and calibrate your

If the problem cannot be resolved by the above solution, please contact us. We are happy to help.

Why the printer prints sideways?

Generally, only when the sizes of your loaded labels, label files, and settings on your devices are the
same, you can print properly.

If you try to print a 4"x6" USPS label sample, please make sure that the paper size at page setup is 4”x6” and your label size is 4”x6”. In this case, the label sample will prints out fine.

If the label file you use or settings you choose is not 4”x6”, you will print sideways. Please adjust
them to 4"x6" first. We suggest that you can long-press and hold the green button to identify and calibrate your label
size each time you change labels.

Why is the red light blinking on the printer?

The red light is an indication that the OFFNOVA Label Printer has not recognized your label and need to re-learn your label. By simply press and hold the green feeder button until you hear one short beep. The printer will move the labels back and forth to learn the gap and other label properties. If the automatic label identification does not work or the red light remains, please turn off the printer and restart it again.

How to print a full size 8.5”x 11” labels?

Some shipping platforms only provide you with a full-page (8.5 x 11") document. For some platforms like eBay, you can choose to download labels at 4”x6” instead of 8.5” x 11".

You can follow the steps below to split this page into a 4"x 6" label
size.
- Download Adobe Reader if you do not have it already from the Adobe website.

Why does the label jam while printing?

1) Please make sure that the sizes of loaded labels, label files, and
settings on your devices are the same.

2) It might be caused by insufficient space during auto-label detection
and self-calibration, please make sure there are enough spaces
between the printer and label holder.

3) Setting the density or speed too high will also cause paper jams. The recommended setting range: speed 4-8 in/sec(101.6-203.2 mm/sec), density 8-14.
If not for the above reasons, please follow the steps below to fix the problem:
a. Put the paper in the printer and turn off the power.
b. Press and hold the white button while pressing the power button
c. Wait until the red light flashes three times and then let go

orientation you need -> Click Print

For Mac:
During the print prompt, click on “printer...” -> Printer Features
-> Click “printer option” under the menu “Feature Sets” -> Setting the print speed and darkness.

alcohol cotton.

Is it suitable for printing logistics labels?

We do not recommend using it for printing logistics labels, as it does not have a self-adhesive feature. For printing logistics labels, we recommend using a shipping label printer.

Can I buy thermal paper in folded packaging?

This printer only supports thermal paper in roll packaging. Please note that the roll diameter should not exceed 50 mm.

Why can't I find or connect to the printer on the Xlife Pro App?

1) Please make sure the printer is powered on

2) Please confirm that you have turned on the Bluetooth function.

If the printing is unclear, what should I do?

You can try changing the concentration to "Dense." It's normal for the printer to make some sound when printing large area patterns in this mode.

When a page is printed, the printer will pause, and you need to manually tear off that page. Afterward, you need to click "Continue Printing" on the app, and the printer will resume printing the next page.
