Printers are essential devices in both home and office settings, and when they start acting up, it can be a source of frustration. A user recently reported encountering the "Print Unable E1" error on their Brother HL-L8350CDW printer, coupled with paper jams, smearing issues, and random restarts during print jobs. In this tech overview, we'll explore possible causes of the error and provide a step-by-step guide on how to address the issues.

Non-Brother Toner Cartridges: Friend or Foe?

The user mentions using non-Brother toner cartridges, specifically from EZ-Ink, and wonders if this could be the culprit behind the printer's sudden troubles. While third-party toner cartridges are a cost-effective alternative, they may not always be seamlessly compatible with the printer, leading to errors and malfunctions.

Troubleshooting Steps:

  1. Toner Inspection: Begin by examining the non-Brother toner cartridges for any visible issues such as leaks or damage. Ensure that they are securely installed in their respective slots.
  2. Replace with Genuine Cartridges: If issues persist, consider replacing the non-Brother toner cartridges with genuine Brother cartridges. This can help determine if the problem is indeed related to the use of third-party toners.

Tackling Paper Jams and Smearing

The user also reports frequent paper jams, both in the front and rear of the printer, along with occasional smearing issues. These problems could be interconnected and may require a thorough inspection.

Troubleshooting Steps:

  1. Paper Path Examination: Carefully inspect the paper path for any obstructions, torn bits of paper, or foreign objects. Clean the paper path to ensure smooth paper flow during printing.
  2. Check for Worn Parts: Examine the printer's internal components, such as rollers and fuser, for signs of wear and tear. Replace any worn-out parts that could contribute to paper jams or smearing.

Addressing Random Restarts

The user notes that the printer is randomly restarting in the middle of print jobs, a perplexing issue that may be linked to various factors.

Troubleshooting Steps:

  1. Power Source Stability: Ensure that the printer is connected to a stable power source. Fluctuations in power supply can lead to unexpected restarts. Consider using a surge protector to safeguard against power surges.
  2. Firmware Update: Check for and install the latest firmware update for the Brother HL-L8350CDW. Firmware updates often include bug fixes that can address unexpected issues.

Additional Considerations

In addition to the specific issues mentioned, it's crucial to keep the following points in mind:

  • Regular Maintenance: Perform routine maintenance tasks, such as cleaning the printhead and checking for software updates, to keep the printer in optimal condition.
  • Temperature and Humidity: Ensure that the printer is operating in a suitable environment regarding temperature and humidity. Extreme conditions can affect its performance.
  • Professional Assistance: If the problems persist despite troubleshooting, seeking professional assistance from a printer technician may be necessary.

By following these troubleshooting steps, users can systematically identify and address the issues plaguing their Brother HL-L8350CDW printer. Remember to follow recommended maintenance practices and consider using genuine Brother toner cartridges for optimal performance.
