Cleaning the print path
Use this process if you discover toner specks or dots on printouts. This process produces a transparency with toner debris, which should be discarded. Note This process requires a transparency to remove dust and toner from the print paper path. Do not use bond or rough paper. Make sure the transparency you use meets media requirements for the printer. If transparency film is unavailable, you can use paper. If you must use paper, perform the procedure two or three times to ensure proper cleaning.

Load a transparency in the priority input tray. Make sure that the printer is in the Ready state. Press and hold the GO button for 10 seconds. The transparency feeds through the printer slowly. Discard the transparency.
Note
After you press and hold the GO button, the three printer lights blink until the cleaning process is complete.
