Corrected: “Making ID Sensor Patterns” paragraph
Making ID Sensor Patterns
The machine makes two different ID sensor patterns, one for Low Duty Mode and one
for High Duty Mode. The mode is determined by SP 2201 004.
If the average copy volume is high (2.5 km/month or more), this SP should be
switched to High Duty Mode to prevent toner scattering.
However, if the machine is in High Duty Mode and the average copy volume becomes
low again, the image density may decrease. If this happens, switch back to Low Duty
Mode.
The ID sensor pattern development bias voltages for high and low duty modes can be
adjusted with SP 2201 002 and 003, as shown in the following table.

SYMPTOM
When HDD Spindle Control is disabled (default), SC980 may occur just after the machine
recovers from Auto Off / Panel Off.
CAUSE
When the machine is brought out of these modes, it is able to warm up quicker than when
the main power is turned on, and therefore checks the HDD status at an earlier point.
However since the HDD must warm up from a stop, it does not reach the ready speed in
time and a mainframe/HDD communication error occurs.
SOLUTION
The default setting for HDD Spindle Control (SP4960-005, 006) has been changed from
Off ! On, which keeps the HDD rotating constantly.
Cut-in serial numbers:
B010-17: From 1st production
B010-22: From 1st production

ACTION IN THE FIELD
When installing the HDD option in the following machines, please change the setting of
SP4960-005 and 006 from Off ! On:

1. SP4960 005,006 (HDD Spindle Control) setting changed
Symptom
When HDD Spindle Control is disabled (default), SC980 may occur just after the machine
recovers from Auto Off / Panel Off.
Cause:
When the machine is brought out of these modes, it is able to warm up quicker than when the
main power is turned on, and therefore checks the HDD status at an earlier point. However since
the HDD must warm up from a stop, it does not reach ready speed in time and a

2. New UP mode added (Weekly Output Volume)
To prevent toner scattering from the development unit (see the conditions below), the “Weekly
Output Volume” setting has been added to System Setting – General Features.
Symptom
When customers use low duty mode to make high-volume copy jobs (relative to the ACV), the
toner concentration in the development unit increases. This causes the oversupplied toner to
drop onto the copies, especially under low temperature conditions.
Solution
Change the “Weekly Output Volume” according to the customer’s average weekly copy volume
from inside System Setting – General Features:
Less than 750m (2,500 ft): Low duty mode (default).
More than 750m (2,500 ft): High duty mode
Action in the field
Please instruct customers on the following points at machine installation:
1) Method for how to enter UP Mode and change the Weekly Output Volume value.
2) For the first 1-2 months following installation, have the customers keep track of their copy
volumes at weekly intervals. The weekly changes in CV over this time will enable them to
decide which of the two settings is best for them.
Note: For customers installing the Dolphin as a replacement machine, please use the weekly
ACV on the previous machine for reference and set the Weekly Output Volume accordingly
(as a starting point).
3) During these first couple of months, if the average weekly copy volume exceeds 750m (2,500
ft), please have the customer change the setting of the Weekly Output Volume to “More than
750m (2,500 ft)”.
Note: Please also check the total counter value at PM visits, calculate the weekly CV, and if
necessary change the Weekly Output Volume setting.

The four symptoms listed below tend to occur if the toner cartridge is not shaken properly
before it is inserted into the toner hopper. This is because transport and storage conditions
can cause the toner to bunch together, which prevents the toner agitator from rotating
properly.
Please be sure to remind the customer at installation that it is very important to shake the
bottle 5 to 10 times before inserting it into the hopper. This is also mentioned on the decal
on the left side of the machine.
1) The toner supply drive gears (B0103126, AB017539) break.
2) The shaft for these drive gears break.
Note: In this case, it is necessary to replace the development unit.
3) The toner hopper cover opens during copying.
4) Add Toner is displayed again soon after replacing the cartridge.

1. New SP Mode added to enable the Ready Temperature Setting function (SP1917)
This has been added in order to prevent insufficient fusing with translucent paper when making
copies just after the machine is turned on. The settings for this mode are as follows:

The default of this mode was changed from "3 seconds" to "instant" for use with the

)
Translucent thickness 3 & 4
)
3. Design-use SP Modes added
SP5959 and SP5957 have been newly added. However, these are strictly for design use only.
Please do not change the values in the field. The defaults are as follows:
SP5959：OFF
SP5957：Disabled
The following items (4 ~9) have been corrected in this version.
4. SMC printout onto undefined paper sizes
In response to a request from the field, the SMC printouts can now be printed onto any
paper size that can be loaded into the paper trays.
5. Occurrence conditions changed for SC353
SC353 will not be displayed during Toner End.
This was changed because sometimes when copying originals with a very high image area ratio,
SC353 would occur unnecessarily when the ID sensor pattern density dropped and the Near
End condition was detected.
6. Jam Recovery
The machine was sometimes unable to perform successful jam recovery if a jam occurred while
printing out a series of preset jobs.
7. Display error - number of jobs
Even after being cancelled, a preset job is not subtracted from the total job count.

8. Part of image missing when printing out "Additional Copies" with electronic sort, mixed
original mode
Following a mixed-original electronic sorting job, the machine is still set to use the paper roll it
did for the last copy.
Therefore when "Additional Copies" are initiated, instead of resetting the paper roll to the initial
one, the machine starts printing out onto the most recently used roll, cutting off some of the
image. The software was corrected so that copies of any additional sets are printed out onto
their correct sizes, i.e. as originally set in the initial job.
9. Unlimited scanning before beginning a copy job
The software was changed so that when the Print Start Trigger is set to "press start key",
originals can be scanned an unlimited number of times before initiating the copy job. Each time a
new scan is initiated, the previous scan data is overwritten.

4. Remove the following NVRAMs
from the MCU board:
IC101 [D] (RAM - STK15C68 - P45)
IC108 [E] (SRAM - STK15C88 - W45)
IC109 [F] (RAM - STK15C88 - P45)
Note:
1) Before removal and insertion, the engineer should touch a metal portion of the
machine to eliminate the possibility of a static electricity buildup.
2) Do not place the NVRAM on an object made of conductive material. This will cause a
short, resulting in the loss of all the data inside.
