Hi Juan,
I will assume your printer is 5XXX series. This error indicates your printer needs Service Station Calibration which is performed as follows:
** Load a WHITE media (Roll or Sheet) that is full width of the Printer before performing this calibration.
First go to "Printer Setup Options" on the front panel and press Enter. Once inside this menu press "Down Arrow" and "Enter" Buttons simultaneously. Press "Yes" and scroll to Service Calibration, press Enter and scroll to Service Station and press Enter.
Continue with the calibration and observe the messages displayed on the panel during and after the calibration and keep me posted please.
Regards,
Saad
