4520-xxx Paper Feed Jams Paper Jams - Base Printer Error Message 200 - Paper Jam - Remove Cartridge This message indicates that paper is jammed at the printer input sensor. This condition can be caused by the paper jamming prior to activating the input sensor flag, the sensor not detecting paper over the sensor or paper arriving at the sensor too late. Note: A defective engine board or printhead can also cause a 200Paper Jam message to occur prior to the paper reaching the input sensor flag. This error can display due to a problem with the HSYSC signal to or in the printhead. Use the sub error code table to assist in isolating a 200 paper jam message. Error Message 201 - Paper Jam - Remove Cartridge This message indicates the paper is jammed between the printer input and exit sensors. This condition can be caused by the paper exiting the input sensor too late or jamming in the fuser assembly prior to activating the exit sensor flag in time or not at all.

This can be caused by the paper arriving at the sensor too late, the paper is jammed in the fuser assembly or is jammed exiting the fuser assembly in the redrive assembly or the exit sensor flag is not operating correctly. Paper Jams - Options Error Message 230 Paper Jam - Check Duplex Unit The paper is most likely jammed in the duplex unit, however the paper can also be jammed in the redrive at the input to the duplex unit.
