Classification:
This RTB has been issued to announce the procedures for troubleshooting low image
density at the trailing edge.
Symptom
Low image density at approx 10mm from the trailing edge
Cause
The nip of the bias roller and PTR is released earlier than the optimum timing.
NOTE: The default value of SP1022-002 was modified (from -70 ms to -120 ms) in the
following Engine firmware version, to reduce "shock jitter":
Copier: Version 1.60:04 (D0745404G) or newer
Printer: Version 1.60:04 (M0445404E) or newer
Action
Modify the value of SP1022-2 to delay the release timing of the nip.
NOTE 1: The value is recommended to be within the range of -70 to -120.
NOTE 2: As a side effect, this adjustment could cause higher chances of "shock jitter."
