I have a persistent blockage in the magenta print head in my stylus pro 3800.
I have been using your inks for some years now and they have worked great. Some time ago I noticed that when I did a nozzle check I had lost several points in the magenta pattern. I did several clean cycles and a power cycle but nothing changed so since it uses so much ink and the prints I was doing still looked perfect I just let it go. Recently I lost more nozzles in the magenta pattern and the prints where no longer as good so I knew I had to do something.
I got some of your piezo printhead flush and filled a refillable cartridge with it and put in the magenta chip and put it in the printer. I did several cleanings to get the flush going through the lines to the head and I also made a 6x9 page in photoshop and made it magenta color and printed several sheets that way to be sure I was getting flush through the lines. I left it for several days and tried another test and the same missed nozzles where present. I have cleaned the capping station and wiper and cleaned the bottom of the print head with the paper towel trick several times but no change.
I have not tried to replace or clean the dampers but since the pattern on the print test is always the same I felt the problem must still be the print head. ANY SUGGESTIONS AS TO WHAT TO DO NEXT?
Is it possible that the head is so blocked that it can not be cleared?
Is there a way of putting pressure on the magenta cartridge or line to force flush through the head?
I am a professional photographer now retired so I do not do a lot of printing with this printer and I realize low volume is part of the problem but I still do some printing and we have several web sites which we have had to make inactive until we get our printer working or get a new one like the 3000 perhaps. Need one that will print with pigmented inks.
I am most impressed with this forum and appreciate any help I can get.
