The CR Motor Drive Issues and Solutions- Fatal Error 0X02 on DTF Printers

Question:
I am using the DTF model J printer, and I noticed that the white and blue lights are blinking together. It shows fatal error 0X02 related to the CR motor drive. I’ve cleaned everything I can think of, but when I turn the printer on, the print head moves up and down over the print head wiper instead of going to the home position. What might be causing this, and what can I do to solve it?
 
Answer:
Thanks for getting in touch with us! We regret the delay in responding. We know that printer problems can seem urgent, but we do try to give complete and careful responses to ensure we’re zeroing in on the heart of the matter. We are very thankful for your interaction and solace, especially about our YouTube channel, BCH Technologies. Your feedback guides us in growing our technical capabilities.
 
What you see in fatal error 0X02, CR (Carriage Return) motor drive error, is usually caused by a bad motor in the CR motor assembly or a failure with associated components related to the failure analysis, etc. Based on your description, the print head moves up and down over the wiper rather than returning to its home position, indicating that the carriage cannot move on the X-axis.
Here’s a rundown on what could be going on:
APG Unit Movement: You stated that the print head goes up and down during this startup phase. This standard printer procedure is called an APG (Auto Paper Gauge) unit check. Here is a list of printers that must be checked before going to their home position. But if the CR motor moves after that and the CR motor can not move the carriage left or right, something prevents it from working correctly.
 
Possible Causes: 
 

• CR Motor Failure: The CR motor itself might have failed. This motor moves the print head along the X-axis. If it doesn’t, the printer cannot correctly position the head, and if it cannot, you get the error message that you see.
• Motor Cable: The CR's motor has to stay connected to the mainboard with the correct wiring or cable. Otherwise, the cable can become loose, damaged, or disconnected. Worn or poorly connected cables can often be the source; inspect them.
• Carriage Belt: The belt responsible for moving the carriage may have been loose or damaged. This may interfere with the print head movement, causing the error.
• The encoder sensor that tracks the carriage's position can be dirty or misaligned. If the sensor is not properly sensing the printer head's position, it simply won’t move to its home position.

 
Steps to Diagnose and Fix:

• CR Motor and Belt: Inspect the CR motor and belt for wear. If they are defective, they may require replacement.
• Inspect Cables and Connections: Examine the cables connected to the CR motor closely. Any frayed, loose, or damaged cables must be repaired or replaced.
• Clean the Encoder Sensor: A dirty carriage encoder sensor can cause mispositioning. Gently wipe it with a microfiber cloth to keep it working.
• Reboot the Printer: If you repaired or adjusted anything, you should reset the printer and check if it eliminates the error code. In Oki's manual, they sometimes recommend just a simple reset to help the printer recalibrate after the mechanical issue has been fixed.

 
Printer issues can be quite frustrating to troubleshoot, as the problems tend to be hands-on. Frankly, we can no longer offer remote troubleshooting, advice, or support for printer repairs. We provide local diagnostic (BCH Technologies Printer Repair Service) for in-person evaluation and remediation.
Reservations are first-come, first-served due to the high demand. We may not be able to bring your printer in for service for a few weeks, but we’ll take good care of it. We treat our services in a way that either a complete printer will be repaired, in which case all the necessary inputs will be given, or a particular portion of it will be repaired, which again will be briefed clearly. But we also know our rates can be expensive. So we highly advise you to do some self-help through the world wide web. Step 1: Visit YouTube (or the YouTube Channel Homepage)
 
Use the search icon next to “About” on the right-hand side of the menu bar to find individual videos. Daily, I get dozens of questions asking if there are videos for various topics. After creating videos in our nine-year history, it is hard to remember each and every single one. So, the best way to look for it all is to turn to YouTube's search function. Plus, YouTube may recommend relevant videos from other channels that may help.
Thank you once more for your reaching out! Thank you for your patience and continued support.
