AN ALTERATION TO THE SOFTWARE OF
SF-2116/2118
1.Model name: SF-2116/2118
2.General: A description of changes which should be made to correct the poor functioning of the
software.
3.Description: 1. The toner control sensor value received when performing Simulation 50-02, part D,
changes from it’s correct base value. (The value changes to 50 or 0, resulting in
‘‘overtoning’’)
2. When Simulation 50-02 is performed, the counter display shows only the last two
digits of the number entered, but after the Simulation is completed, if the number that
was entered is called up again, only the first two digits are displayed.
* Machines equipped with versions of ROM earlier than Version 2.5 show the
malfunction mentioned in (1). Please carry out all adjustments using Simulation 50-01
and avoid the use of Simulation 50-02. Because it is necessary to use the values from
RRC-A and RRC-B in the calculations, we have prepared a chart containing those values
Please refer to it when necessary.
4.Changes: Software update - from Ver. 2.2 to Ver. 2.5
5.Action: July, 1995 production on.

[Carrying out the adjustments using the reference chart]
(Adjustment instructions)
á Place the scale marker on the manuscript unit.
í
Press the keys in the order indicated above. (Simulation 50 will commence) The
READY lamp will come on and the value previously entered (anything from 1-99) will be
displayed. This is the RRC-A information.
ó Set the values for A and B and then make copies at 100% and then 200%.
ú Measure the distance from the edge of the paper to the end of the scale measure, and
find the values for RRC-A and RRC-B, as explained below.
If the preset value for RRC-A is not correct, the positioning of copies at different
magnifications will differ. RRC-B is a preset value which is designed to adjust the
timing of when the RRC goes on, so that the front of the copy will match the front
of the image on the drum.

• L1: Distance at 200% (mm)
• L2: Distance at 100% (mm)
Copy made at a

Measure L1 and L2, and then use the chart to check them against the values in RRC-A
and RRC-B.
(Example) L1 = 23 mm L2 = 16 mm
RRC-A = 43
RRC-B = 69
a) Press the % key until the counter display shows ‘‘A 0"
b) Enter the values shown below to set the values for RRC-A and RRC-B.
Proceed according to the instructions from b) in the service manual in order to complete
the adjustments.
