No cleaning was successful, finally replaced the printhead and solved the problem.

SOURCE: When printing in color a yellow line appears on document

A horizontal line U say and U don't have problems in B&W pages.... ( on the length or width af a A4 page?) the yellow line is just a line or parallel lines at the same distance?.
1-st of all try replacing the Y cartidge.

SOURCE: printer output has shadows, blurring, streaks, lines, poor color

Seem like blocked hole(s) on the color print head...
Most likely if there is a deep clean option then do it (may need a few times to unblock a hole or never).
Also get the printer physically cleaned up if you can see dusts inside (vrtical lines on color bars).

This sounds like a registration problem.

Use the menu (on the printer) to print antest page AND a configuration/information page.

Look (critically) at the alignment of the seperate coloure Yellow Magenta Cyan. You will probably find that these are out of aligmnent across the page.

The cause of this, is that the printer can't perform a calibration properly (printer probably takes a long time when calibrating too) and is usually down to failure of one of the sensors on the transfer belt.

Sometimes you can clean these and solve the problem, but often is a failure of the component itself. Thes are NOT available as a spare part, and the repair to correct this would need a replacement transfer belt.

Transfer belt replacement in this printer is quite an involved task, though it is within the capabilities of someone with reasonable mechanical aptitude.
