I only use OEM ink or toner on machines in my office or at client machines. Thank you so very much Deepak for coming back on this interesting issue with the PageWide 477dw printhead! Depaak, do you know about air in the printhead and how air can get into? Is it possible that air gets into printhead by cleaning prinhead in the described method shown in the You Tubes? PageWide operators should know that since many of us will end up seeing these You Tubes, following the cleaning method and possibly end up in the same problem. Since this was not helping with my problem having the black printing like bar-codes, I assume that it can only be air in it. In so far we can understand where we are and what we do. Read carefully and follow all steps finding 21 Tab cleaning etc. 18Ħ1 tap results (Align and color calibrations). 16ġ2 tap test results (REDI sensor values). Even though it did not help, I figured out where PageWide users can find these remedies to solve such a problem if it is caused by ink smudge ( see Google PageWide Pro 352/377, 452/477, and 552/577 Troubleshoot Manual, go to Perform tap tests and interpret results.
