2. SC396 – SC399
Excerpt from RTB RM077086c
Recommended actions to prevent & resolve SC396 – SC399.
Update the Engine firmware to Version 1.009:16 or later.
In a system forced termination, developer mixture accumulates at the nip between the dev
roller and drum, because the dev roller and drum stop suddenly. This generates excess
load on the drum rotation in the recovery operation. (See "Cause No.4 and 5" in the table
on the next page.)
The new f/w (Ver1.009:16) pre-rotates the dev roller in the recovery operation to remove
the developer mixture accumulating in the nip between the dev roller and drum, which
prevents abnormal drum rotation (SC39x).

Version
1.009 :16 Specification changes:
1. To meet the Energy Star Ver2.0 standards, ITB alignment control values
are no longer stored on the NVRAM during monochrome printing.
2. Higher reliability against SC39x (drum-lock); machine warm-up following a
forced termination is performed after activating the development motor.
3. Higher reliability against Jam 170 when alternately running A3/DLT and
A4/LT staple jobs.
NOTE
When applying this firmware, make sure to upgrade the firmware for SR5020
to Ver.3.19 (P/N: D4345620N) or newer.
