Print quality has gone down hill. Used refills, as well as, new OEM cartridges. It has been kept clean, externally. Inspection with flex-light and mirror revealed a mess on both sides, where ink has apparently leaked profusely. There is considerable dust mixed with the ink and there is a good coating of dust over the entire internal surfaces. I did not want to open it up without a diagram or procedural instructions....which is not available from HP. ANY help would be appreciated greatly.
Thank You,
Jim
