The process takes approximately 6 minutes. IMPORTANT: Do not open any covers during this process. Recalibrate the paper advance Accurate paper advance is important to image quality because it is part of controlling the proper placement of dots on the paper. If the paper is not advanced the proper distance between printhead passes, light or dark bands appear in the print and image grain may increase. The printer is calibrated to advance correctly with all the papers appearing in the front panel. When you select the type of loaded paper, the printer adjusts the rate at which to advance the paper while printing. However, if you are not satisfied with the default calibration of your paper, you may need to recalibrate the rate at which the paper advances. See Troubleshooting print-quality issues on page 136 to determine whether paper advance calibration will solve your issue. Recalibrating the paper advance procedure 1. From the front panel, swipe down the dashboard and touch , then scroll down the menu and touch Printer maintenance > Paper advance calibration > Calibrate paper. The printer automatically recalibrates the paper advance and prints a paper advance calibration image which you can send to stacker or basket. 2.

If you are dissatisfied with the recalibration, return to the default calibration, see Return to default calibration on page 107. 3.
