Troubleshooting Printhead Crashing on ProColored L1800 Based DTF Printer

Question:

Hello, I have a ProColored L1800 based DTF printer, and the print cartridge is bumping into the right side wall upon boot up, then throwing a code. You can hear the motor trying to take the cartridge a little too far. What do you recommend I do?

Troubleshooting Printhead Crashing on ProColored L1800 Based DTF Printer:

The issue you're experiencing is often due to the printhead not knowing its correct position. This can be caused by several factors:

1. CR Encoder Scale (Clear Belt or Timing Belt):
   • Check for Damage or Misalignment: The CR encoder scale is a clear belt or timing belt that helps the printhead determine its position. Inspect the belt for any signs of damage, dirt, or misalignment.
   • Cleaning: Use a lint-free cloth to gently clean the encoder scale to remove any dust or debris.
2. Encoder Sensor:
   • Proper Insertion: Ensure that the encoder is correctly inserted into the encoder sensor. Sometimes, it may get dislodged during maintenance or transport.
   • Functionality: Check if the encoder sensor itself is functioning properly. If it's faulty, it may need to be replaced.
3. Sensor Cable and FFC Cable:
   • Connection Check: Verify that the sensor cable and the flat flexible cable (FFC) are securely connected. A loose connection can cause the printhead to lose track of its position.
   • Cable Integrity: Inspect these cables for any signs of damage or wear. If the cables are faulty, they will need to be replaced.
4. Mainboard Issues:
   • Mainboard Check: If all other components seem fine, the problem might lie with the printer's mainboard. This is a more complex issue and might require professional assistance or a replacement of the mainboard.

To systematically troubleshoot this issue, follow these steps:

1. Turn off the printer and unplug it from the power source.
2. Inspect the CR encoder scale for any visible damage or dirt. Clean it gently if necessary.
3. Check the encoder sensor to ensure it’s properly inserted and not damaged.
4. Verify all cable connections, especially the sensor and FFC cables. Ensure they are securely connected and free from damage.
5. If the problem persists, consider testing the sensor and mainboard for any underlying issues that might be causing the malfunction.

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. So, 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. We appreciate your support and engagement, and we hope this helps resolve your printer issue.
