Re: Firmware for bizhub 550i/650i without A800 Memory Board

That would interest me too. Unfortunately I can't answer that. Apparently I don't have full rights in Knova. I can't find the RFEU_BT2210861EN.
But I'm not sure if a missing board will perform the same speed.

I can't see it, too on KNOVA....

I checked BSLJ online parts manual for same "changes" and that's some info if you pick the memory board:

- For Japan (AC74/AC75001), USA (AC74/AC75011) and Europe (AC74/AC75021) destinations, "Memory board", "Mounting Plate",
"Power source harness" and "Screw (V125030803)" ) 4 pcs" have been discontinued. [Figure 1]
- Due to the above parts discontinued, "PWB Assembly(PWB-BASE ASSY)" and "PWB Assembly(PWB-CPU ASSY)" have been added
for Japan (AC74/AC75001), USA (AC74/AC75011) and Europe (AC74/AC75021) destinations.
- Two bent points of "I/F Flat Cable /W" have been added.
Due to this, the part number of "I/F Flat Cable /W" has been changed. [Figure 2] [Figure 3]

[Parts Combination]

The following parts are not compatible as single part. It becomes possible to exchange new part reported with this PMN since the Applied Machine Number in applied Product info. - "PWB Assembly(PWB-BASE ASSY)": AC75H02801 - "PWB Assembly(PWB-CPU ASSY)" : AC74H02Y00 (for bizhub 650i) / AC75H02Y00 (for bizhub 550i) In addition, The following parts will continue to be supplied as service part only for machines equipped with "Memory board" in the market. - "Memory board" : AC74H02A01 - "Mounting Plate" : ACDF135201 - "Power source harness": AA2JN15B00 - "Base Board Assembly" : AC74H02101 - "CPU Board Assembly" : AC74H02P08 (For bizhub 650i) / AC75H02P08 (For bizhub 550i)

[About Machine Identification]

The machines equipped with "Memory board" and machines not equipped with "Memory board" can be distinguished by the applied machine number. - The machines equipped with "Memory board" : S/No. AC74xxx0yyyyy (The 8th digits of Applied Machine Number is "0", "x": Model No. Last 3 digits, "y": Applied Machine Number) : S/No. AC75xxx0yyyyy (The 8th digits of Applied Machine Number is "0", "x": Model No. Last 3 digits, "y": Applied Machine Number) - The machines not equipped with "PWB Assembly(A800)" : S/No. AC74xxx7yyyyy (The 8th digits of Applied Machine Number is "7", "x": Model No. Last 3 digits, "y": Applied Machine Number) : S/No. AC75xxx7yyyyy (The 8th digits of Applied Machine Number is "7", "x": Model No. Last 3 digits, "y": Applied Machine Number)

The same modification bulletin (KOM220414E0) is attached to the CPU + baseboard so I think they made same changes to these parts for making that memory board obsolete.
