Clean the encoder strip
1. Make sure that the printer is not printing and that the carriage is located in the service station on the right-
hand side of the printer.
2. Using tap water and a small cloth that will not leave bers in the printer, dampen the cloth and remove any
excess water, so that the cloth is damp but not wet.
3. Open the printer window.
4. Hold the cloth in an inverted U shape around the encoder strip and carefully wipe until no further ink
residue appears on the cloth. Be very careful not to scratch the encoder strip with your
ngernails or any
other object. Make sure that you are holding the cloth correctly.
NOTE: Do not move the carriage away from the service station.
5. Close the printer window.
6. From the front panel, tap , then Image quality maintenance > Replace printhead. The carriage moves
to the left and stops in the correct position to remove the printhead.
7. Turn o the printer by pressing the power key and then unplugging the power code.
8. Open the printer window and move the carriage further to the left, allowing you to access the service
station.
9. Clean the part of the encoder strip inside the service station as described above.
10. Close the printer window.
11. Turn the printer back on.
If you would like further guidance on this procedure, see the Service Manual.
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 satised 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 93 to determine whether paper advance
calibration will solve your issue.
Recalibrating the paper advance procedure
1. From the front panel, tap , then Image Quality Maintenance > Paper advance calibration > Calibrate
ready paper. The printer automatically recalibrates the paper advance and prints a paper advance
calibration image.
2. Wait until the front panel displays the status screen and re-print your print.
NOTE: The recalibration procedure takes approximately three minutes. Do not worry about the paper
advance calibration image. The front-panel display shows any errors in the process.
