EPSON Stylus Pro 7600/9600 Revision A 3.3.4 Smudged or Marred Printout (Reverse side) If smudging or marring of the paper back surface with ink occurs, the following items should be checked. 1. Check to see if there isn't ink adhering to the paper feed path. If there is ink adhering, it should be wiped off. Sub-platen A/B Surface Grid roller surface Paper guide L surface Paper guide L2 surface 2. One likely cause of ink adhering to the above parts is the following cause. Paper feeding at a slant during printing (at the point when 1 page is finished) The ink absorbing sponge for "borderless printing" is deformed or swelling. C A U T IO N If the Paper Skew Detection setting is off in "Printer Settings" → "Panel Setting Menu" → "Paper Width Detection," if the user's paper size setting is not correct, the surface of the platen will be printed. 3.3.5 White or Black Banding in the carriage running direction If white or black banding (uneven density) in parallel with the carriage running direction appears on your printout, check the following points: 1. Nozzle Check Pattern Printing (p.45) Select "Adj: Check Nozzle" in the Adjustment (p.230) menu by the self-diagnostic function. Check the following points: Dot missing Head ID setting value If dot missing is found, execute head cleaning. (If deemed necessary, select and execute "Power cleaning (p.60)" in the SelecType mode or "Cleaning (p.259)" by self-diagnostic function.)If the Head ID value is wrong, set the correct value. 2. Adjustment If dot missing is not found, perform the following adjustments and check for improvement: Paper feed correction (driver) Head Slant Adjustment (Mechanical Adjustment) (p.247) If each line of nozzles in the head is perpendicular to the carriage running direction correctly, the raster lines printed with nozzles can overlap or be dislocated, so that black banding (uneven density) or white banding (blank spaces between raster lines) may occur. If the adjustments above do not work enough to improve the quality, try to improve by executing Feed Correction + T&B Adjustment (p.239) by the self-diagnostic function.
