#1 Hi @charbelchaaya5230,

My first recommendation would be to try to perform a printhead cleaning routine but if the issue persists probably you should replace the printheads. Another "good practice" is to check if the maintenance cartridge is good conditions.

Please, let me know if this helps, Warm regards,

#4 After seeing the image. I would recommend replacing PrintHeads and maintenance cartridge, but as you said it was already done. I would call a service engineer to have a better understanding of the issue.

#4 Hi charbelchaaya5230, problems are with not good contact of printheads in the carriage. You must clean very good the printheads contacts and the little gold dots on the strips where printheads are sitting. When we first installed printheads, half of them were like first picture posted by you - there LM/LC printhead is Offline . About the condition of printheads - try to print from Settings -> Image quality -> Clean printheads -> Print test plot...
