Embroidery Machine PR620 [Maintained within the last 6 months] + 4 Hoops

This is a Brother PR620 commercial 6-needle embroidery machine.

I purchased it used on another site in February.
My handmade items are not selling well, so I am listing it as I will not be using it.

The previous owner had it overhauled in November of last year for around 60,000 yen (see image 6). It has been used for approximately 28 hours since its last maintenance. Thread cutting and threading are good, and the bobbin case area is clean. (The third line from the top in the final image shows the time since reset.)
⚠ Needle #3 could not be used during maintenance and cannot be repaired.
When I used it, needle #5 also caused an error and stopped.
I am unsure of the cause for needle #5; it may be due to my usage.

Image 3 → The numbers indicate needle numbers.
You can assign a color to each needle, so if you use 4 colors or less, you can sew without changing threads. For 5 or more colors, you will need to change the thread once, and then you can sew up to 8 colors.
I was able to sew patches and similar items without any problems.

I also took a video of it embroidering, but it seems I cannot upload it to Mercari. I plan to take a video of the four needles in motion before shipping.
