4069-5XX/7XX First 6 Bytes Sub Error Code Data - Note: xx can be any value. Explanation 89 00 01 The exit sensor in the fuser is activated by a piece of media indicating there is a piece of media in the machine during POST. *Check for media in the exit of the fuser assembly or redrive assembly. Feed a sheet of paper, and if the same error occurs after clearing the fuser or the same error occurs when no media is present, check the exit sensor assembly, internal fuser assembly cabling, DC fuser cable to the system board, and the cable connection to J14 on the system board. TIP: Turn the printer off, enter the diagnostic tests menu, and select the base sensor test. Select output sensor and check the sensor for correct operation. 89 xx 03 The fuser exit sensor did not detect the trailing edge of the media going through the fuser assembly. *This failure can be caused by a broken fuser exit sensor flag. *This may also be caused by erratic operation of exit sensor flag or exit sensor or a defective piece of media. 89 xx 04 x1 The fuser exit sensor never actuated from the sheet going through the fuser before the next page begins feeding. (x-1=Media Size) 89 xx 07 The narrow media sensor in the fuser was covered by a sheet of paper when not expected or a piece of media is in the machine during POST. *This error can occur when a 202 paper jam has occurred. *Remove any piece of media that is over the narrow media sensor. *Try to feed a piece of paper through the printer (could run the print test from the diagnostic test menu). If the media stops over the narrow media sensor again, check the flag and sensor for correct operation. 89 xx 0B x1 The fuser exit sensor may be bouncing. *This error can be caused by a failing exit sensor or system board.
