Blue streaks when printing - Sharp MX-2700N Color Copier

If you're holding the paper so the narrow side is up, and the blue streak is vertical, then it's not a bad print head. If the stripe is from side to side with the paper held that way, then possible that the head is bad. The 4530 is an office type printer with large carts that connect to the print heads with hoses. It's possible that a hose has come off and is dumping ink that way, or that the hose is leaking...

Uninstall and install the cartridge and do a re-alignment, this should help.

Mam, try replacing the cyan (blue) image unit may have a bad cyan image unit.

If that lines are consistent with the red and blue and it does not appear during black and white print that means the cleaning blade in the affected color units need to be replaced

The blue streak is likely caused by a bad cyan cartridge, not a bad belt. That will clean off after you replace the cartridge. The misalignment problem sometimes requires 3 complete full calibration cycles to eliminate the error.

Had a similar problem. Tried lost of things. In my case, the streaks cleared up after I cleaned the toner drum.

ok..save the window..those print heads are clogged, and good. You MAY need to run that print cleaning at least 8 times, to get that gook out of there.

Try removing the printhead (cartridges first, careful where you put them, they'll make a mess) then clean the print surface with a window cleaner and cotton swabs.
There may just be deposits on the surface and this is not far from the paper surface.

Check to see if you have a paper jammed near the drum near the color ink cartridge interface.
