Troubleshooting the Procolored L1800 DTF A3 Printer: Fixing APG Unit and Sensor Issues

Question:

Hello, I purchased a used L1800 DTF printer, but I have never gotten it to work. I noticed that the APG unit's motor isn't connected to anything, and it lacks the two sensors. Can the printer run without these installed?

No, the printer cannot run properly without the APG unit's motor being connected and the two sensors installed. The APG (Automatic Paper Gap) unit is essential for ensuring the correct paper alignment and feed during the printing process. Without the motor connected and the sensors in place, the printer will not function as intended, leading to various operational issues.

Detailed Steps to Resolve the Issue:

1. Check the APG Unit:
   • Ensure the motor of the APG unit is properly connected. The motor drives the mechanism that adjusts the paper gap, which is crucial for accurate printing.
   • Inspect the APG unit for any visible signs of damage or disconnection. If you need a new APG unit, you can get it here.
2. Install the Sensors:
   • The two sensors on the APG unit are vital for detecting the main rod's position and ensuring it turns correctly. Without these sensors, the printer cannot properly manage the rod position.
   • Refer to detailed guides or videos to correctly install these sensors. For a step-by-step guide on how to install the APG unit and sensors, you can watch this video (https://studio.youtube.com/video/G_lZLqRH_f0).
3. Firmware and Software Checks:
   • After ensuring the hardware is properly installed, check for any firmware updates that might address potential issues with the printer's operation.
   • Ensure your printer's software is up to date and that there are no conflicts causing the malfunction.
4. Run Diagnostic Tests:
   • Use the Epson's Adjustment tools to check for any other issues. This can help identify problems that are not immediately visible.
5. Consult the Manual:
   • Refer to the printer’s manual for specific instructions related to the APG unit and sensors. The manual often provides troubleshooting steps that are specific to your printer model.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. For instance, resolving a simple clog might involve advice on unclogging procedures. However, if the printer remained inactive during downtime, a comprehensive service for the ink system could be necessary. Situations like a "paper jam" can arise from hundreds of potential causes, and solving such an issue has become something of an in-office jest. Therefore, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis, so it might take a few weeks before we can get your printer to drop it off or mail it to us. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed if you opt for mail-in or local drop-off services. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage (https://youtube.com/@bchtechnologies). Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.

Thank you again for contacting us, and we hope this information helps you resolve the issue with your Procolored L1800 DTF printer. If you need further assistance, feel free to reach out.
