Hello everyone,
Recently I have had a problem with the black channel of my Epson 9890. The printer I took it in second now.It worked steadily. There are no more than 1000 printing pages at the coumpter. The scans of the printer are attached. the degradation of the black channel in an interval of 2 months. Nozzles clogged or the head begins to delaminate?. Try to fill with Piezo flush?
Thank you very much for your help.
