The new models, “Kingfisher 2 (A298)” and “Grand Kingfisher 2” will be launched in
November ‘99. They are slightly modified versions of the already existing models
“Kingfisher (Ricoh FT4015, Gestetner 2715z, Nashuatec 3715, Rex-Rotary 8715Z, Savin
9115, Infotec 5151 z)” and “Grand Kingfisher (Ricoh FT4618, Gestetner 2718z, Nashuatec
3718, Rex-Rotary 8718Z, Savin 9118, Infotec 5181 z)”.
There will be nine destination codes for Kingfisher 2 depending on the area: -27 is Europe

The following SP modes have been added to the KF2/GKF2.
SP 70 (No UP mode)
-User Code Mode selectionFunction: Enables User Code Mode.
Procedure:
1) Access SP mode 70.
2) Select 1:user code mode (Default is 0: No user code).
3) The machine is then ready to access the next mode number.
Note:
Cut JP101 on the main board.
Procedure to set the user code:
1) "U2" is displayed in the copy counter. Using the number keys, input the three-digit user
code number (e.g.111,123,999). Please note that 000 is invalid.
2) Press the Auto Image Density key.
3) "U2" is no longer displayed and the machine becomes ready to copy.
If any invalid values are entered or other keys are pressed, "U2" will rema in displayed
and copies cannot be made.
4) After the copy job is completed (or one minute after the last key is pressed), the
machine initiates Auto Reset and becomes ready to set the next user code. At this time,
"U2" will be displayed and copies cannot be made.
5) As an alternative, you can set the next user code by pressing the Clear Mode/Energy
Star key and then the Clear/Stop key when the machine is in Copy Ready condition.
The machine will then become ready to accept the next user code.

SYMPTOM:
1) At machine installation or after the developer is replaced, SP66 (TD sensor Initial
Setting) that would usually take about 60 seconds stops after only a few seconds.
2) After a new machine is installed, copies have high ID and/or toner drops onto copies.
This occurs until about 100 copies are made.
CAUSE:
The TD sensor connector (A1905346: Development Unit Harness) which is mounted on
the I/U (Imaging Unit) is not properly connected to the connector of the Development
Relay Board (A1905145). The board is mounted on the rear side plate of the mainframe.
If the service technician does not tighten the knob screw
raised portion of the mainframe front side plate, the TD sensor connec tor will no t be fully
inserted into the receiving connector on the board.
To check whether or not the connection is stable, make some copies and check the
reading of SP55. If the connection is unstable, the SP55 reading will also be unstable (e.g.
71,125,13,17,117,35).

against the raised portion of the front side plate of the mainframe (see the illustration
below). While holding the unit in this position (pushing on the handle), tighten the knob
screw (A1902320) by hand until the I/U is secure.

SYMPTOM:
The image density of the leading (top) half of the copy becomes lighter when specific light or
halftone originals are copied.
CAUSE:
When the 1st and 2nd scanners start to move, part of the light from the 1st scanner is directly sent
to the mirror of the 2nd scanner, as the two scanners are relatively close. This "extra light" received
by the mirror will cause the image to appear lighter. As scanning continues, the 1st scanner
increases to twice the speed of the 2nd scanner, causing the two scanners to get farther and
farther apart. Therefore, less and less light "extra light" reaches the 2nd scanner mirror. This is why
the image is lighter near the leading edge.
SOLUTION:
A shading seal (A2981684) should be attached to ensure proper image density at the leading edge
(when making copies with very light/halftone originals). Because the extra light passes from the
2nd scanner mirror to the photoconductor via the base plate of the optics unit and lens carriage
(A1901682), the seal should be attached to the lower portion of the lens carriage. This will prevent
the extra light from passing between the optic base plate and lens carriage.
This modification will be applied from August 2000 production.
Please see the procedure as shown below.

An equivalent grease for plastic can be used instead of the above ones.
Note: Cosmos No.1 grease was applied to the tip and spiral threads of the worm gear at
the motor vendor as of July 2000 production motors onward.
2) Replace the worm gear with a new one (P/N A2983388) and apply grease to the tip and
spiral threads of the gear.
Note: The material of the new worm gear was changed to NW-02 to improve durability,
and it will be applied from the February 2001 production machines onward. We
will issue a modification bulletin (MB) to inform you of the new part number of the
toner supply motor (the motor service part includes the worm gear) and the cut-in
machine serial numbers.
Please do not order the new parts until the MB is issued, as they are not yet in
stock.
