Question: Hi, I'm a member of your BCH channel, and I was considering getting a custom-built Epson L1800 direct-to-garment printer. Here is a topic I faced recently where, on starting, the printer shows two flashing lights. I’ve included a video of the problem in this email. Do keep your networking skills close when diagnosing the issue.
Answer: Thanks for sharing your thoughts with us. I'm sorry for not getting back to you sooner. Unfortunately, printer problems can be rather urgent, so I want to give you the best specific and detailed advice to help with your situation. BCH Technologies sincerely thanks you for engaging with us and supporting us, particularly our YouTube channel. Your feedback is critical in aiding us in improving our technical proficiency and providing better solutions.
Watching the video you provided, I noted the printhead raises, lowers, moves to the extreme left end of the printer, and returns as part of the startup. Your printhead only moved halfway before reversing, and it was because it was broken. Furthermore, the printer showed an error code 05H, which refers to the CR (Carriage Return) encoder's abnormal condition,n which could happen due to the following issues:
Check for Blocks and Deforming:
Remove any paper jams, foreign objects, or dried ink build-up from the printhead carriage area.
It is important that the timing belt be correctly aligned and not sloppy, as misalignment will affect the carriage's movement.
Check the Timing Belt and the Encoder Strip:
Congratulations on replacing the encoder strip! Make sure it is tensioned and in the right position. A 05H or 52H error can be created if the belt is too tight or loose.
Could you check that the CR encoder sensor has not been displaced and is fitted correctly?
Verify the CR Motor and Encoder Sensor:
The CR motor moves the printhead. A malfunctioning motor often causes 05H errors.
The same thing happens with the print head error in the Epson adjustment program scan error history. Repeated failure of the CR motor may signal a repeating problem.
Make sure the encoder sensor is working properly, as its failure can lead to the printhead's unstable position.
Check the Flexible Flat Cable (FFC):
The FFC cable connects the encoder sensor to the mainboard and makes accurate communication possible. Check the cable for damage, fraying, or loose connections.
Could you make sure the lead is well inserted on the salter board and the salter board?
Assess the Mainboard:
If everything else is working fine, the mainboard may be to blame. A board failure usually requires professional diagnosis and replacement.
Next Steps:
Texte explores the root cause of the error by checking every bit one by one. If you still experience unfortunate behavior after fixing these possible causes, please consider a professional to check/change a mainboard.
Troubleshooting printer-related problems can be complicated because most of the issues are hands-on. Unfortunately, we cannot help you with remote troubleshooting, recommendations, or repairs to your printer. We also provide an in-facility diagnostic and repair service (https://bchtechnologies.com/printer-repair-service), which is first come, first served due to demand and may require a few weeks’ wait for a drop-off. Our services are to repair a full printer or specific sections of a printer with instructions on how to go about it. However, we understand that our rates may not be the cheapest and strongly suggest searching online for self-help options.
We recommend first going to our YouTube channel (https://youtube.com/@bchtechnologies) and searching with the search icon for relevant videos. There’s nearly a decade of content, so it’s the fastest way to identify anything you need to know. YouTube might also recommend helpful other-clear videos that take you further.
Once again, we appreciate your patience and support. We’re here to help you in any way we can.

- Problems with the timing encoder sensor.
- Motor driver failure.
- Slack in the timing belt.
- In severe cases, a failed mainboard.
- Issues with the encoder strip or sensor cable.
