BULLETIN NUMBER:
APPLICABLE MODEL:
GESTETNER – 6002/7502
RICOH – AFICIO 1060/1075
SAVIN – 2560/2575
SUBJECT: NO WEB END CONDITION DISPLAYED
SYMPTOM:
The entire Fusing Web has wrapped to its end, and the "Web End Condition" has not displayed on the
operation panel.
NOTE: This only occurs when using BCU Firmware version 3.12 and the 9-bin Mailbox.
CAUSES:
A firmware bug sometimes causes the value of SP1902-002 (Fusing Web Motor Operation Interval) to
become corrupt. This can occur when the front door is opened/closed, or when the main power/operation
switch is turned Off/On. If this value is changed to 0, the machine may energize the Web Motor and wrap
the web forward, all the way to the end condition.
NOTE: This SP setting determines how long of a printing interval (cumulative) is allowed before the
machine runs the motor. The default is 18 seconds with the 60 cpm model (B064), and 15
seconds with the 75 cpm model (B065).
SP1902-001 is the primary determining factor for SC550 (Web End Condition). If the web reaches the
end condition due to the firmware bug, no "Web End Condition" will be displayed.
SOLUTION:
Modify the BCU firmware to version 3.14 or higher.
Version 3.14 Firmware changes
Web end detection will be determined by the Web End Sensor regardless of the value of SP1902-
001.
The value of SP1902-002 cannot be changed under the conditions outlined above.
