I've installed quite a few CISS for people. I'm currently using Melco Technologies as my main CISS supplier that I install.
I'm wondering if anyone has any experience or success in install CISS into a Canon MP520.
I did one this week, and while the install seemed to be successful, after two or three pages of printing, it started to colour mismatch and jitter text. It got progressively worse with each page printed.
I've checked all the cartridges and the tubing routing and it all seems OK. Ink is flowing to each cartridge.
The install was quite fiddly, probably the most I've come across in 50-60 installs across various makes and models of printers.
Once I reinstall the original cartridges all is OK again, so it is not blocked nozzles.
I'm using the Melco C04 model CISS.
So, to hear from anyone who has done this in a MP520 would be helpful.
