Question: I installed a drag chain and replaced the dampers with a nipple conversion. However, I encountered a paper jam error even though no paper was installed. I fixed the paper jam but faced issues pulling ink into the dampers. The ink lines are complete, but some colors must flow correctly, even with the new dampers. What could be the problem?
Answer: Thank you for reaching out to us, and we apologize for not being able to respond sooner. Printer issues can be pretty frustrating, and we understand the urgency of your situation. We want you to know that we aim to address your concerns thoroughly to ensure your printer functions optimally. At BCH Technologies, we’re grateful for your support and engagement, primarily through our YouTube channel (https://youtube.com/@bchtechnologies). Your feedback helps us refine our expertise and better serve the printing community.
Let’s break down the issues and possible solutions:
1. Fixing the Paper Jam Error
It’s great to hear that you resolved the paper jam issue! The error was likely caused by the drag chain obstructing the printhead carriage’s movement. This obstruction can trigger the printer to detect a paper jam falsely. To prevent future occurrences, manually move the printhead carriage and check for areas where the drag chain might get caught. Adjust or secure the drag chain to ensure it doesn’t interfere with the carriage pathway.2. Troubleshooting Ink Pulling Issues
Pulling ink into the dampers can be tricky, especially with DTF printers. Here’s a detailed step-by-step guide:-
Check the Ink Supply:
Ensure the ink flows smoothly up to the printhead. Use a syringe to draw ink from the damper outlet. Hold the damper upside down while pulling ink so air bubbles rise to the top and ink fills the damper. This ensures no air pockets disrupt ink flow. -
Proper Damper Installation:
When inserting the damper into the printhead, handle it carefully. Avoid squeezing the damper, as this can cause ink to spill. Insert the damper while maintaining its upright position. -
Parking the Printhead:
After installing the dampers, turn the printer on to allow the printhead to park naturally on the capping station. To avoid misalignment, it’s crucial to do this with the printer powered on. -
Priming the Printhead:
- Connect a syringe and tube to the printer’s waste line.
- Gently draw 1.5 ml of air. You should feel a slight resistance, indicating a proper seal.
- If you only draw air, the printhead may not be seated correctly, or there might be a leak in the capping station seal.
- If there’s complete resistance, the capping station could be clogged. Resolve this before proceeding.
-
Cleaning the Printer:
Use the printer’s standard cleaning routine to flush any remaining air from the lines. Avoid performing multiple vigorous cleanings within 12 hours, which could damage the printhead.
3. Additional Tips
DTF ink is thicker than regular ink, so it might take extra effort to prime the printhead properly. If these steps don’t resolve the issue, inspect the capping station, waste line, and dampers for clogs, leaks, or mechanical problems that might interfere with ink flow.Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we cannot provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service (https://bchtechnologies.com/printer-repair-service) via our local diagnostic facility. Given the high demand, we operate on a first-come, first-served basis. Drop off or mail in your printer might take a few weeks. Our services are structured to repair a whole printer or specific parts, with clear instructions on proceeding if you opt for mail-in or local drop-off services.
We acknowledge that our rates may not suit everyone’s budget. Therefore, we highly recommend exploring self-help options, such as online research or our YouTube channel (https://youtube.com/@bchtechnologies).
