Poynt Terminal: Image Processing Error on Receipt... | terminalfaults.org

Technical Background:

Image processing on the Poynt Terminal involves software routines converting image files (e.g., logos) into a bitmap format suitable for the thermal printer. This process relies on sufficient RAM, CPU processing power, and a functional printer driver. Errors can occur due to corrupted image data, insufficient memory allocation, driver malfunction, or thermal print head issues.

Symptoms:

Receipts are printed without logos. An 'image processing error' message may be displayed or logged.

Possible Causes:

Corrupted logo file: The image file stored on the terminal may be damaged or incompatible.
Insufficient RAM: The terminal may be running low on available memory due to other running applications.
Printer driver error: The printer driver responsible for converting the image data to the printer may be malfunctioning.
Thermal print head issue: The thermal print head may be damaged or dirty, preventing proper image transfer.
Communication error: Intermittent communication errors between the processing unit and the thermal printer.
Firmware bug: A software bug in the terminal's firmware may be causing the image processing error.

Solution:

1

Safe Handling: Unplug the Poynt terminal from its power source.
2

Restart the terminal: Reboot the Poynt terminal. This clears the RAM and restarts the operating system and printer service.
3

Check logo file: Verify the logo file format is compatible (e.g., monochrome bitmap) and the file is not corrupted. If possible, try re-uploading the logo through the Poynt HQ portal.
4

Clear Printer Queue: Navigate to the settings menu on the terminal and clear the printer queue.
5

Update terminal software: Check for and install any available software updates for the Poynt terminal.
6

Test print: Perform a test print using the terminal's built-in diagnostic tools to verify printer functionality.
7

Cable Check: Inspect the cable connecting the printer (if external) to the terminal for any signs of damage or loose connections.

Safety Warning:

Ensure the terminal is unplugged before performing any external inspection or cleaning. Avoid using excessive force when connecting or disconnecting cables. Static electricity can damage the terminal, particularly in dry environments. Ground yourself by touching a grounded metal object before handling the device.

Prevention:

Regularly clear the Poynt terminal's cache and restart the device to maintain optimal performance. Ensure the logo files are stored in the correct format and are not corrupted. Implement cable strain relief measures to prevent damage to connectors.

Expert Tip:

Try accessing the Poynt terminal's diagnostic menu (if available – consult Poynt's official documentation for the key combination). This menu often includes printer tests and error logs that can provide more specific information about the image processing failure. If the problem persists after software updates and cable checks, the internal thermal print head might have an issue, which will require professional servicing by an authorized Poynt technician.

Frequently Asked Questions

•What is the correct image format for logos on Poynt terminals?

Monochrome bitmap (.bmp) is generally recommended. Consult Poynt's documentation for the precise specifications.

•How do I update the software on a Poynt terminal?

Software updates are typically installed automatically overnight. However, you can manually check for updates in the settings menu.

•Where can I find the diagnostic menu on the Poynt terminal?

Consult the official Poynt documentation or contact Poynt support for instructions on accessing the diagnostic menu. The key combination varies by model.
