Specification Changes:
The default values of the following SPs were changed from 10% to 3% to
achieve more precise and appropriate timing for indicating the pre toner near
end message.
SP3110-11 TNE Detect (Lvl1) SetDisp Timing: K
SP3110-12 TNE Detect (Lvl1) SetDisp Timing: C
SP3110-13 TNE Detect (Lvl1) SetDisp Timing: M
SP3110-14 TNE Detect (Lvl1) SetDisp Timing: Y
For more detail, please refer to RTB RD074108.
Notes on limitations:
* The new default value of 3% does not appear in the SP.
(Current controller firmware -System/Copy ver1.13 or older for Copier, System
ver1.07 or older for Printer- only supports an adjustment range of 10%-100%.)
* DO NOT modify these SP values. Modifying these SP values will set the
default value back to 10%. Once modified, the new default of 3% value cannot
be retrieved.
* Modify these SP values only when they need to be set to a value higher than
10%, which should be decided based on the job operation requested by your
customer.
* The above limitations will be resolved in the succeeding controller firmware
version to be released.
