Explanation
This code indicates that the media activated the input sensor before the printer EP
was ready.
(x1=leading edge of media state, x2=trailing edge of media state)
The transfer servo never started.
(x1=media size, x2=leading edge of media state)
This code indicates that the media has activated the input sensor before the
printhead has locked. Enough time has elapsed since printhead start to expect a
lock.
One of the following may be failing:
• Printhead assembly
• System board
• Printhead cables
This code indicates that media has activated the input sensor; however, the
printhead fell out of lock condition or not enough time elapsed since the printhead
start to expect a stable lock. The media may have also reached the input sensor
early.
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.
Service 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.
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.
The fuser exit sensor never actuated from the sheet going through the fuser before
the next page begins feeding.
(x1=media size)
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.
1. Remove any piece of media that is over the narrow media sensor.
2. 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.
The fuser exit sensor may be bouncing.
This error can be caused by a failing exit sensor or system board.
The fuser exit sensor bounced. Check the exit sensor for correct operation. Check
the fuser DC cable to J14 on the system board. Also, the system board may be
failing.
