TSP143III Printer: Post-Print Reset Diagnosis - Solar Faults | terminalfaults.org

Technical Background:

The TSP143III reset issue may originate from voltage fluctuations during the print cycle, triggering the printer's internal protection mechanisms. The printer's logic board relies on stable voltage; variations can cause a reset. Baud rate mismatches are unlikely to cause a hard reset, but can cause print errors. Electrostatic discharge (ESD), especially during dry conditions, can interfere with the printer's operation, causing spurious resets. Signal attenuation, from a damaged cable or a long cable run, can also interrupt communication and be misinterpreted as a fault, prompting a reset.

Symptoms:

TSP143III printer resets immediately following the completion of a print job. This behaviour consistently repeats across multiple print attempts.

Possible Causes:

Power supply unit (PSU) delivering unstable voltage under load (printing).
Loose or damaged power cable causing intermittent power loss.
ESD interference causing the logic board to malfunction.
Faulty or outdated printer driver causing software conflicts.
Excessive cable length or damaged data cable causing signal attenuation.
Spurious signals or noise on the power line affecting the printer's internal voltage regulation.

Solution:

1

Perform a Safe Handling procedure: Disconnect the power cable from the printer and the wall outlet.
2

Inspect the power cable for damage (cuts, fraying). Replace if necessary.
3

Verify the power outlet is functional using a different device. Test with a known working device.
4

Ensure the power adapter is securely connected to both the printer and the power outlet.
5

Download and install the latest printer driver from the Star Micronics website.
6

Test the printer with a different data cable (USB or Ethernet) to rule out cable issues.
7

If the problem persists, consider a factory reset of the printer (refer to the Star Micronics manual for instructions, but be aware of potential settings loss).
8

Check if the problem appears on other Terminals. This can indicate a larger store power issue.

Safety Warning:

Avoid touching the printer's internal components. Do not use excessive force when connecting or disconnecting cables. Ensure the power cable is disconnected before performing any maintenance. Static discharge can damage the printer's electronics. Ensure proper grounding to prevent ESD build-up.

Prevention:

Regularly clean the printer exterior with a dry, lint-free cloth. Avoid cable strain by ensuring cables are properly routed and secured. Consider using a surge protector to stabilize the power supply. During dry seasons, use an anti-static wrist strap when handling the printer.

Expert Tip:

Try a different power outlet on a different circuit. Sometimes, shared circuits can experience voltage drops when other equipment is operating, causing printer resets. Consider installing a ferrite choke on the power cable to reduce EMI.

Frequently Asked Questions

•Is the printer connected to a dedicated power circuit?

A dedicated circuit can minimize voltage fluctuations.

•Has the printer's firmware been updated recently?

Outdated firmware may cause unexpected behaviour.

•Are there any other devices on the same power strip as the printer?

Other devices can cause power surges or drops.
