Symptom

Paper jams with the sorter stapler jogging function can occur under the following
conditions:

1. When ST33 (20 bin S/S) is used with Cattleya 2 (B023).
NOTE: If it is used for Cattleya 1(A257/A269), this will not occur.

2. When LT (11"X8 1/2") sideways is used when making 2 or more copies of an original.

Cause

The S/S main ROM software cannot compensate for the higher copy speed of Cattleya 2.
The timing of the jogger function and paper feeding does not match that of Cattleya 2.

Solution

When installing the ST33 on Cattleya 2, replace the S/S main ROM with ver "G" or newer.
The ROM version of the S/S main board can be viewed with copier SP7-801-005. The last
digit (for example G) indicates the ROM version. Version G can also be used for Cattleya1.
The part number of this new main ROM is A8315111.

Program upgrade in mass production

The main ROM upgrade (ver G) has been applied from the first January 2001 production
run for each S/S. The cut-in serial numbers are as follows:
A831-17: H141130001 (see NOTE-1).
A831-26: 3T60110001 (see NOTE-2).
A831-55: L0551XXXXXX (see NOTE-3).

NOTE

1. "H14" is the prefix number. The 4th digit refers to the production year (1 = 2001). The

5th and 6th digits refer to the production month (13=January, 14=February, ........,

23=November, 24=December).

2. "3T6" is the prefix number. The 4th and 5th digits refer to the production month

(01=January, 02=February,........,11=November, 12=December). The 6th digit refers to the

production year (1 = 2001).

3. "L055" is the prefix number, The 5th digit refers to the production year (1 = 2001) and
the 6th and 7th digits refer to the production month (01=January,

02=February,........,11=November, 12=December). Because there are currently no A831-

55 models in production, there is no cut-in S/N at the moment. Please note that although
the Cattleya 2 has no Lanier model at present, there are cases in which A831-55 is used
with models other than Lanier.
