SAVIN – 4090/40105
SUBJECT: JAM CODE 53
SYMPTOM:
Jam Code 53 sometimes occurs when LT LEF is fed from the tandem tray 1.
NOTE:
Jam code 53: The tandem tray paper feed sensor detects the presence of paper past the
predetermined time period (a certain number of ms after detecting the paper's leading edge).
This symptom only occurs in under the conditions described above, and not with any other paper
sizes or feeding trays.
CAUSE:
The paper sometimes slips and does not clear the paper feed sensor in time. This allows the next sheet fed
to catch up with it and cause the Jam Code 53.
SOLUTION:
Update the BCU firmware to version 4.10 or later. BCU Firmware version 4.10 or later can be downloaded at
the Technology Solution Center FTP Site at http://tsc.ricohcorp.com. Be sure to check the README file for
important notes and explanations. Refer to Technical Service Bulletin B070/B071 Firmware History dated
11/07/2003 or later for more information concerning BCU Firmware version 4.10.
