Symptom Corrected
Black lines in halftone areas.
Software modified so that no transfer current can be applied to
the development roller surface after the main motor has stopped.
Change in detection conditions:
To decrease unnecessary occurrences of SC350/392, the
detection conditions have been changed as follows:
1) TD sensor 4V adjustment error must occur twice (check cycle
is repeated).
2) Allowable interval (4V adjustment) changed from 80ms to
100ms.
If a tray (optional tray unit) is installed but not fully pushed in
when the main power is turned on, there is no status display at all
for that tray.
Specification change:
If the Copy Reset Timer is set to "off", the Program User Code
and Change User Code screens (Copy Features - Key Operator
Tools) will not be cleared once the operator has started code
input.
Note: If enabled, the Energy Saver Timer and System Reset
Timer will reset the screen (same as before).
Specification change:
The key counter will not count up when the Printer Counter List is
printed out.
When performed, SP7-808 (Reset Counters) would mistakenly
clear the Copy, Fax, Printer, Duplex and A3/DLT counters.
Note: This error did not affect (clear) the Total or Timer counters.
Despite key counter user restrictions, it is always possible to print
out faxes.
In addition, faxes are not recorded by the key counter (only by the
total counter).
The Start Key does not turn green after the original scanning
memory becomes full and the remaining originals are re-set for
the next scanning (cannot continue).
Conditions:
SP5-940 (Image Rotation) = 1 (disabled).
Rotation Sort is selected
An even number of sets is programmed
In Text mode, Background Removal does not completely remove
the background surrounding light text characters (e.g. text written
in pencil).

Symptom Corrected – see older RTBs for previous changes
When SP4-942 (Black Line Erase) is set to "2", the image
appears split into several horizontal lines.
Specification change:
Firmware modified so that even when the machine is in the
middle of a Key Counter copy job, incoming fax or printer
jobs will be accepted.
The setting options for SP4-942 have been changed as
follows:
Old: New:
0: none 0: none
1: weak
1: weak 2: normal
2: strong 3: strong
The level of the old "1: weak" is the same as the new "2:
normal".
Specification change:
As a countermeasure for fuzzy image borders, the transfer
current for Special Mode (envelopes) and for the 2nd side of
duplex prints has been changed.
When Special Mode (envelopes) is selected, the value for the
paper slack set in SP1003 (Paper Feed Timing) is increased
by 5 mm.
Change in detection conditions:
To decrease (unnecessary) occurrences of SC392, the detection
conditions have been changed as follows:
1) TD sensor 4V adjustment error must occur twice (check cycle
is repeated).
2) Allowable interval (4V adjustment) changed from 80ms to
100ms.
