The use of cheap ink is always an element of risk, because the standards are not to judge. So far, I am quite well run with NoName-ink, in this case it went wrong. No sooner were the cartridges in it, the nozzles of cyan, magenta and yellow were tight. Even after each repeated cleaning the nozzles were tight again in no time. The question of whether this might not be on the print head, has done with the exchange by Original Ink: A complete set of Canon ink in the printer, and everything works again.
