Doped Ink: KI Doped Ink for Medical Phantom Printing (MD100-DPI)

The main board works again! Prior to purchasing the main board, my Epson WF-3640 would give the 0x9a error code, which I deduced was due to a short-circuited clogged printhead, that blew out the fuse on the main board. Disassembling the printer, I had checked the main board fuse with a multimeter and sure enough, it was blown. So, I chose to buy a main board from BCH, as I was sure I could not fix the fuse itself. I also bought some new cables for the print head/main board as one of them looked burnt where it was inserted in the print head. I purchased a used printhead elsewhere, though, as BCH didn't seem to have one in stock. After installation, the printer worked again, though the used printhead--again purchased elsewhere--was clogged. I can't blame that on BCH, which is why I stress that I purchased the printhead elsewhere. Nevertheless, everything from BCH worked perfectly. It may work too perfectly, for when I initially powered up the unit without ink cartridges, I didn't get any error message saying to install cartridges. I don't know why that is. It could be just the way the WF-3640 works and I had never noticed it before, but once everything was installed, it merely said the nozzle and/or printhead was clogged and asked me to run a cleaning. All in all, I am very satisfied and would purchase from BCH again should I have the need to do so. Lastly, the YouTube videos and BCH website instructions were spot on! I had initially wired back the mainboard incorrectly but I re-watched the video and found my error before I powered up the unit. My only regret is that I accidentally may have left the "Anonymous Anonymous" review below without adding text, which I have remedied with this comment.

Very please with my purchase and its delivery Purchasing from BCH was easy and efficient from start to finish. It was easy to order, I was able to easily track my order, and what was delivered was a quality product delivered when they said it would be. No complaints here! I would definitely order from them again!

Dear Kevin I was very pleased about the very helpful information on your website, which I could not get from Epson Germany. The part is exactly what I need. Shipping to Germany was very fast, 10 days crossing the Atlantic from home to home, super. Thanks Dietmar
