1. Establishment of ADF and RADF original copy tray scales as service parts.
1.Model Name: SF-A15/A55/2050
2.General: The original document tray scale of the models listed above had not been established
as service parts, and therefore they have now been registered as service parts.
2. Correction of PWB parts codes.
1.Model Name: SF-S55
2.General: The part code of the IC (Q46) used in the main control PWB was doubled (two part
codes were listed for the same part). To correct this error one of the part codes has
been eliminated.
0GZWA45214000 ← This part code should be used when placing orders for the part.
0GZWA46214000 ← Eliminated
3. Sequence of operations to be carried out during the option test mode.
1.Model Name: SF-1020/2020/1120/ 2120
SF-A57/A18/S54
2.General: An error was discovered in the content of the service manual, and when carrying out
the option operations test mode in accordance with the mistaken content of the service
manual on machines which have had an option (SF-A18/A57/A54) installed for the
models listed above, the machines will not operate properly. To alleviate this problem,
the following sequence should be used.
