In order to have a good nozzle check to let us work we need to clean and clean more then 15 times (and even more...). Now I can not anymore to obtain a complete nozzle check. The cleaning itself (strong) works well. I looked at the draining hoses and a lot of paint goes out during the cleaning operation.
Initially (two years before) we discovered that the ink is not good enough and in order to properly use it we need some filters. We did that and we worked well until last month. last week I changed the filter on Magenta. Some air goes on the pipes and I filled the intermediary tank using the filling procedure from service menu. I was thinking that the air going inside the intermediary tank reach now the dumper, but it is a single dumper for two sides of magenta... How the left one is always complete and only the right side one is damaged? Could that be a problem of dumper itself?
Like a strange thing which maybe can have some relevance is the fact that the day before yesterday I cleaned and cleaned until the end of the program with very bad results. Yesterday without any new cleaning the nozzle check was good. Only a missing line but I start working and after the printing the nozzle check was perfect...
Thanks in advance!
After editing: I have just opened the head cover and I looked at the dumpers. The magenta one does not have air at all! Can be this the cause? If yes, the supposition of just disconnecting it from pipes and reconnecting will introduce enough air in order to make it showing like the neighbors...?
