Reference for Canon Service Tool v4720

This is actually my 2nd CISS system. The first was from a vendor preassembled and filled for plug and play with a Canon 2720. After installing it, I realized that the 4x45ml capacity wasn't clearly stated and is much too small. I then swapped out the tiny Black 45ml tank with a BCH 500ml tank. Easy. 45ml colors are sufficient. I can run the Canon for 4 months. More importantly I learned how a CISS is assembled and it's operating characteristics. Today I ambitiously added a 500ml BK and 3x75ml Color tanks to my Brother MFC-5930DW refillable cartridges. I have to refill the cartridges every 2 weeks. Now I should have at least 4 months between refills. BCH had all the parts to build my CISS and explanations on how the CISS bottles work and their positioning.

I bought a printer "customer return" from a liar on eBay. The thing was heavily used and by no means a returnable item. Though he gave back half, I had no idea if I was gonna recover anything more but B.C.H. came through and had the parts necessary for me to rebuild it.

Bought these transistors to fix my motherboard great price but what was even better was the shipping cost under $2.00. So many times I’ve had to order a small cheap part and was charged over $10.00 for shipping on a $1.00 part. My part was sent out fast and arrived a day earlier than expected. So an A++++ on customer service. I will definitely shop here again if I need parts for my printer.
