The Aficio 400 has been modified to resolve the following problems.
Problem :
1) SP 4907
Because of a problem with soft ware, auto letter/photo separation only works when
SP4907 is set to NO. This should be the other way around.
2) SP 4909
All of the settings in SP mode 4909 are "0", which produces improper images.
They should be reset in the following manner.

- 4 60
- 5 192
- 6 0
- 7 16
- 8 128
Countermeasures:
Starting from the June Production run, the software has been modified.
When in SP mode 4907, auto letter/photo separation will work when the setting is YES.
Also, as a result of this modification, the default values for SP4909 1to 8 have been corrected.
For the machines manufactured before June, please take the following temporary
countermeasures:
Please set SP 4907 to NO to use auto letter/photo separatione and vice veras.
Also , please set the default values for SP4909 as indicated above.
When you install new ROMs, the SP Mode settings are reset to the default values.
The SP Mode settings should be reset back to what they were before the ROM was replaced.

3. SC Codes
The following SC codes have been added.
SC303: Time out error for printer
NOTE: This SC303 has already been assigned as "Charge wire cleaner error". However,
this SC code has been assigned again by mistake. Now, two SC303s exist.
If an optional charge corona wire cleaner has been installed, to determine which
SC303 has occurred, turn the main switch off. After switching it on again, if
SC303 still exists, it is the "charge wire cleaner error."

Problem
1. Abnormal images, such as partially blank copies, dirty background, etc. appear.
2. One of these service codes is displayed: SC320, SC321 or SC322.
Cause
IC55 (RF5VG094) on the IPU board breaks down. There are defective lots of IC55 for the
EX-IPU board on the Aficio 400. Those defective IC55s have been incorporated into the
production of the Aficio 400 for the months between June and August. Those lot numbers
are 6DH4P, 6EH4Q and 6FH4R on the IC55 for the EX-IPU board.
Countermeasure
Replace the IPU Boards in the machines that contain the ICs from the defective lots.
Field Measure
We will send the amount of EX-IPU Boards necessary to cover the targeted machines. We
have already replaced the IC55s in a portion of the machines overseas. The machines in
which the IC55s have already been replaced have been circled on the attached lists. The
machines with the serial numbers that are not circled should have their EX-IPU Boards
replaced during the next visit to the user’s location.
We plan to re-use the EX-IPU Boards so please be sure to return them to us.
