4 mm Silicone Plugs for Ink Refill HP 88 564 920 940 950 932 XL (6 PCS)

GREAT!!!!! I've been using this ink for my Epson printer and my aunts printer for 4 years now. I've found no faults with it .No bleed through or fading, It just works.

Great!! Worked like it supposed too!! You guys been a great service to the people that like to work on equipment that they bought for personal use! Or maybe work environment!... and I'll be advertising for BCH on how prompt and educational you guys are!!.... thank you for your service!!

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.
