Are you sure about that error code? It doesn't show up at Printers Copiers Servicing - Reference Manual. under any Toshiba model. It makes me think there is no C553. =^..^=
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

From the manual:
C553: DSDF-CCD module error
Fatal Error - Peak detection error
[C553] Peak detection error
The light source of the DSDF-CCD module does not light, or there is a detection error of the light source.
Check item Measures
HDMI cable Check if the HDMI cables (CN78 and CN90) are connected properly.
DSDF I/F board • Check if the DSDF I/F board is installed in the SYS board properly.
• Check the connector (CN89) of the DSDF I/F board.
• Check if the connectors on the DSDF I/F board are disconnected from the DSDF control PC board or the harnesses are open circuited. Correct if any.
• Replace the DSDF control board.
Connector • Check if the connectors of the SYS board and the DSDF control PC board are connected properly.
• Replace the harness.
Power supply Check if 24V is supplied to the DSDF control PC board properly.
• Check the connector of the power supply of the DSDF control PC board: CN70 Pins 1 and 2.
• Check the connector of the power supply of the SYS board: CN122 Pins 19 and 20.
DSDF exit motor • Check if the DSDF exit motor is working properly.
• Check if the connectors (J991 and CN77) on the DSDF control PC board are disconnected from the DSDF exit motor or the harnesses are open circuited. Correct if any.
DSDF-CCD module • Check if the connectors of the DSDF-CCD module and the DSDF control PC board are connected properly.

There was a bulletin about this issue shortly after the MR-4000 was released. It's caused by damage done to the board on the DSDF's CCD module. The fix is to replace the entire module with the updated version. I replaced several of these under warranty in the first year.
Why does every customer think they're the first one to ever say: "you've been here so much we should get you an office, ha, ha, ha"?
The fault is created by the CCD unit in the DSDF document feeder but can also damage the SYS-board (most common). I had this problem two times with different machines.
Be carefull to replace one at the time, because one can destroy the other. Good luck!
