The printhead is probably clogged. Even with alcohol or specific solvent, it is sometimes impossible to dissolve the mix of dry ink and dust.

The only way is to replace the printhead. The reference is CN688A.

However, the teardown of the printer (To access the printhead) is not easy but remains feasible...

There is a few comments on french web sites about many things

- reboot the printer it is a software well known bugg

- do for that special menu commands

- put a new firmware in place

Do a good wash af the ink system

By dissolvant on web site and do expenseives an long time things

the most fun is put pressure into the cartige with an air injection

just after funny : do a special reset by change type of paper because the bugg will be reset

ARRRF ARRRF ARRRF : we are on the net every idiot could say something ...!

Fortunatly a guy explain simply and with pictures how to desmont and acced to the head printer and how to exchange it

A specialist work but accessible and very more efficient than all the other things I described in first

And there is the ref of the spare part

So that is THE solution to solve the print problem and not put again money into a new printer

Thank you again to reasonables peoples who are helping the others with there experiences
