Troubleshooting ET-8500 Printer DTF Film Detection Issues: A Guide to Resolving Sensor Problems

Q&A:

Q: My printer now picks up paper without issue, but it fails to detect film unless I insert white paper in the rear. Previously, applying painters tape worked, but this no longer solves the problem. Could this indicate a malfunctioning sensor, and what steps should I take to resolve this?

A: Thanks for contacting us. We at BCH Technologies are grateful for your engagement and support, particularly with regard to our YouTube channel. Your feedback plays a crucial role in further developing our technical expertise.

The issue you're encountering with your printer not detecting film, but functioning correctly with white paper, likely stems from a problem with the page width sensor. This sensor is responsible for detecting the edges of the media being fed into the printer. When it comes to transparent or semi-transparent materials like film, the sensor can struggle to recognize the material's edges, leading to the printer not acknowledging the film's presence.

Originally, your workaround using painters tape to create a more detectable edge was an ingenious solution. However, the sensor's continued failure to recognize the film without white paper suggests a potential change in the sensor's sensitivity or a shift in the material's properties that prevents the tape from being as effective.

To address this issue, you have a couple of options:

1. Adjust Printer or Software Settings: Some printer models allow you to disable or adjust the sensitivity of the page width sensor through the printer's driver settings or RIP (Raster Image Processor) software. Explore the settings in your printer's driver or any RIP software you might be using to see if adjustments can be made to better accommodate film printing.
2. Switch to a Heavier Coated Film: Using a more heavily coated film, such as double matte film, can improve the sensor's ability to detect the film. These materials have a more pronounced edge and a surface that the sensor can more easily recognize.

Moreover, I strongly recommend joining two Facebook groups that could further assist you in your DTF conversion journey.

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. Hence, we're unable to provide remote troubleshooting, suggestions, or support for printer repairs.

We offer an in-person evaluation and repair service via our local diagnostic facility BCH Technologies Printer Repair Service. Given the high demand, we operate on a first-come, first-served basis. Therefore, it might take a few weeks before we can attend to your printer if you choose 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. 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
