TSC barcode printer red light or can not measure paper

When the TSC barcode printer's red light is on or the paper cannot be measured, it may be due to a variety of reasons. Here are some common causes and solutions:

First, the cause of the red light and the solution

The printer did not measure the paper correctly

Symptom: The red light is steady on or blinking.

The solution:

Press and hold the PAUSE key to start the machine and let the printer retest the paper.

If this method does not work, try holding down the PAUSE and FEED keys at the same time to start, and release the indicator after blinking to see if it solves the problem.

Label Settings are incorrect

Symptom: The actual size of the label is not set correctly in the software.

The solution:

Ensure that the parameters, such as label width, height, and spacing, set in the software are consistent with the actual label size.

Sensor type selection error

Symptom: The sensor is not set correctly based on label paper type (e.g., spacing, black label, continuous paper).

The solution:

Confirm the label paper type and select the corresponding sensor type in the printer Settings.

The printing mechanism is not compressed

Phenomenon: The printing mechanism is loose, resulting in failure to measure paper or print normally.

The solution:

Check and press the printing mechanism. Note that some models, such as the 243 series, may not apply to this method.

Hardware failure

Symptom: After the above check, the problem still persists.

The solution:

It may be a hardware failure of the printer, such as a damaged sensor. At this time, it is recommended to contact a professional after-sales service or maintenance organization for maintenance.

Second, can not measure the paper reasons and solutions

Labels are incorrectly installed

Symptom: The label is not installed correctly.

The solution:

Reinstall the label by following the installation instructions that came with the printer.

Paper problem

Symptom: The label size is not standard, the gap is inconsistent, or the quality is poor.

The solution:

Replace standard, high-quality label paper.

The sensor is faulty or in an incorrect position

Symptom: The sensor cannot sense the label correctly.

The solution:

Clean the dust on the sensor surface to ensure that there is no obstruction.

Check that the sensor position is correct and adjust it if necessary.

Software setup problem

Symptom: The paper Settings in the software are inconsistent with the actual Settings.

The solution:

Adjust paper Settings in the software based on the actual label paper size.

Iii. Summary

When the TSC barcode printer has a red light or can not measure the paper problem, the first should start with simple operations, such as retesting the paper, checking the label paper installation and setting. If the problem remains unresolved, consider the possibility of hardware failure and contact a professional for repair. At the same time, regular cleaning and maintenance of the printer is also an important measure to prevent such problems.
