1. Carryover SP modes from Copier firmware: Currently UNUSABLE.
The following are the SP modes carried over from the Copier firmware
which will therefore appear on the display, as the printer firmware is
created using the Copier firmware base. Please note that currently
these SP modes should not be used on the printer, therefore please DO
NOT CHANGE their values.

[0 ~ 14 / 3 / 1 s/step] DFU
-SP2-925-001 (ITB Cleaning Execution Variable)

2. Extra toner may sometimes stick to the transfer roller and then to the
rear side of the next sheet (main motor off-timing has been optimized).
3. An SC481 (Transfer belt mark detection error) or SC280 (Image
transfer belt mark detection error) misdetection may occur when the
main motor rotational direction is changed from backwards to forwards.
4. The machine may freeze up with the display “Processing,,,” when the
timing of OPC lubricant interruption (SP2-939) conicides with oil
removal mode (SP2-970).
5. Finisher jam misdetection may occur while the sheet is moving
inside the finisher.
6. A black image area may appear blank on the next sheet if paper is
loaded in the tray during Paper End before the printer engine comes to
a stop.
Note: Along with this BICU version, be sure to update the main unit
controller firmware to v2.30 or later.
