Question:
I watched your video and changed the CR sensor cable, but my Epson 1390 print carriage slams. I checked the connections, and everything seems to be connected. I also replaced the encoder strip, but the problem persists. What do you think I should do next? What is the price for a new sensor board?
Answer:
Thank you for reaching out! We are very sorry for the delay in addressing your concern. We understand how urgent printer issues can be and want to ensure every question is given the detailed attention it deserves. At BCH Technologies, we deeply value your support, primarily through our YouTube channel (https://youtube.com/@bchtechnologies). Your feedback is instrumental in enhancing our technical expertise and creating more helpful content.
Replace the Sensor Board
This tutorial assumes that you have already replaced the CR sensor cable and encoder strip (as shown here), so we are moving on to check or replace the actual CR Sensor board. It is also an important board because it passively interacts with the encoder strip, tracking where the carriage should be. When a sensor board is defective, it can misread signals, resulting in the carriage moving erratically by coming down too quickly.
Action:
They can usually be found on eBay and other platforms if you do not have a replacement sensor board. Could you take out the old sensor board and replace it with a new one? Could you align all connections during installation because torn can lead to additional problems?
Test the Mainboard
If you change the sensor board and still no dice…and I hate to have been put through that…I believe it could be in the printer's mainboard…. The sensor board provides data to the mainboard, and the print carriage is controlled by movement.
Diagnosis:
Special tools are needed to measure whether the mainboard is handling signals properly. If it is faulty, then buying a new one seems like an obvious solution.
More Troubleshooting Steps
The Encoder Strip Should Be Aligned And Clean:
Re-verify the Encoder strip for correct positioning and cleanliness. If an encoder strip is slightly off-kilter or dirty, it can lead to improper signal reading, which could cause the printer carriage to slam. If necessary, you can also wipe the strip with a cloth and isopropyl alcohol.
Connection Checks:
Make sure all the connections between the CR sensor, sensor board, and mainboard are connected properly. Loose links could disrupt signal transmission.
Professional Support Options
Printers, in particular, are one of those ubiquitous devices that can still be a very hands-on issue. We are unable to troubleshoot, or provide any other support for installing a printer. The only exception is an onsite evaluation and repair service by our local humbler diagnostic facility (^)(https://bchtechnologies.com/printer-repair-service).
Because of the demand, this service is first come, first served, and it could be a few weeks before we can take your print. Our services include repairing the printer or individual parts; we outline what needs to be done next.
We may not always have the best pricing around. We suggest that you do some online research into self-help methods. Go to our main YouTube channel page (https://youtube.com/@bchtechnologies) and click the search icon on top of that “About” tab under right menu bar, you can enter keywords for searching video with your problem. It is the quickest way to find tutorials relevant to you; someone else might have made a helpful video, too.
Thank you for reading and engaging with our advice. If you have any more questions or worries, ping me. And, as always, thanks again for being part of the BCH Technologies family!
