ET-8550 Mainboard CJ20 – Fully Tested & Ready to Print NO RETURN AS IS

Best thing ever!! i used to put cleaning solution in the capping station with a syringe/hose then had to suck out f the wast line with a syringe.... over and over until the capping station was clean. maybe up to 10 times. now i just use maybe 1 or 2 - 30ml syringes full of water and the pump cleans it out so good.... then I put capping solution, place printhead over capping station and turn on the back of the machine. thats it. when i print again, usually next day, I pull from waste tank a few times until I get ink, then i run 1 head cleaning , print a test strip and usually good to go. I sometimes print a 2nd test strip. SO MUCH easier to use this little pump. so glad I bought it.

This is a must have modification to save time troubleshooting. You will need to download Kevin's capping station video to disassemble the capping station. A definite must. You will also need a few other connections to hook this up. All parts are linked in his videos. Pro tip. Have patience and go slow. This modification will save you from a lot of headaches . I did this mod on Procolored L1800 about a year old . Thanks Kevin.

I purchased this product and messed it up first time. I somehow got superglue onto the main circuit board on the colour cartridge and for some reason (not sure how) I messed up the black one too. I repurchased the product (x2). I tried again with the colour one first (which is meant to be the most difficult). I was careful to wrap the circuit board and print head in cling film and taped it down on top. I was careful with the superglue and let it dry upside down for 24 hours so that if the glue leaked anywhere it wouldn't go towards the circuit board. It works great. I now have a functioning refillable colour cartridge. I am glad I got the hardest one out of the way first. I will shortly try the black one. But fantastic that overall, I know this product will save me a fortune in printing now. The colour one is obviously the hardest and it works! Good job guys. (I am from the UK which is why we spell colour with a u lol).
