Support Printers All-In-Ones WorkForce Series Epson WorkForce ST-C8090

I still see white or dark lines in my printout after cleaning the print head three times. What should I do?

  • If you still see white or dark lines or missing nozzles in your printouts, even after cleaning the print head several times, you can run a Power Cleaning.

    If you do not see improvement after running a Power Cleaning, turn off the product and wait at least 12 hours before running another Power Cleaning.

    Caution:
    Running a Power Cleaning consumes a lot of ink, so you should run it only if necessary. Make sure each ink tank is at least one-third full before running a Power Cleaning, or it may damage the product. Power Cleaning may cause the maintenance box to reach its capacity sooner. When the maintenance box is full, you need to replace it to continue printing.
