Symptom Corrected Suffix
The firmware was modified so that it can be used with the scanner controller for Adonis-C1.
The machine sometimes scans part of the exposure glass scale and edge of the original. To
prevent this, a new scanner SP mode has been added (SP017, Scanner Margin Adjustment).
Note:
After installing this firmware version, Scanner SP006 must be performed.
The machine stalls when the memory full condition is reached. F
When Scanner Auto Clear is enabled:
If an ADF jam occurs during a scanning job initiated before the Scanner Auto Clear timer expires,
the scanner settings are reset to the defaults.

SYMPTOM
When using the scanner function, the machine sometimes scans part of the exposure
glass scale and the edge of the original. A black line appears on the scanned image.
CAUSE
Scanning starts from the upper-le ft hand corner o f the exposur e glass. Ther e for e, w hen
the original is curled or not lined up flush against this corner (platen mode) or when DF
feed is late (ADF mode), the machine scans part of the exposure glass scale and the edge
of the original.
SOLUTION
A new scanner SP mode has been added (SP017, “Trimming”) so that the scanning
margin can be adjusted. This SP mode was made available with the release of scanner
controller firmware version 4.0.0. After installing
to perform SP006 to reset the UP and SP settings related to the scanner.
The details of this SP mode are as follows:
Scanner SP017
No Function Settings
017 Trimming
Adjusts the scanning margins for both the main and
sub scan directions.
The larger the value, the wider the margin.
Note:
This problem occurs only when the machine is set to scan the entire original, not when
scanning a selected area within the original. Therefore, this SP mode does not apply to
cases where the Preview function is used.

Examples:
1. When the machine scans an A4 sized original in Platen Mode and the value of SP017 is
5 (illustration 1 below):
Since the scanning start position is at “A”, margins will placed at 5 mm from the left and
right edges (main scan) as well as from the leading and trailing ed ge s (sub-scan).
Any image within 5 mm of the four edges will be erased.
2. When scanning a selec ted area with the Preview function in Platen Mode and the valu e
of SP017 is 5 (illustration 1):
Since scanning starts from point “B”, the 5 mm margin is not applied to the selected
area, and nothing in this area is erased along either scan direction.
3. When the machine scans an A4 sized original in ADF mode and the value of SP017 is 5
(illustration 2):

In ADF mode, the original is centered along the main scan direction. Although the subscan direction margins are applied to the original (as in example 1), the main scan
margins will not appear (left/right edges). This is because the machine applies the 5 mm
main scan margin using reference point “C” (where scanning begins), and so the
centered A4 original is too narrow for the main scan margin to appear.

SYMPTOM
The scanner controller may not connect with some types of hubs at 10 Mbps, depending
on the particular hub and scanner NIB combination.
CAUSE
The OSC5 oscillator on the scanner controller does not match the particular hub.
SOLUTION
The OSC5 oscillator has been changed. The new controller is A8775311 (A8775310N).
Note: Initially, this was only a suffix change, however later we changed the part number to
A8775311.
