No. Problem content Cause and Description
Simulation 46-2 (exposure adjustment) has been added. The exposure adjustment settings have been set to each
1
When copy operations are carried out after placing A4R
copy paper in the ADF and the ADF tray sensor has
registered A4, the original document is scanned as A4R
2
but the image area is A4. (This problem occurs only
when the shadow compensation mode is in effect.
When simulation 41-1 is carried out the operation LED
corresponding to the original document does not
3
illuminate.
When multi-manual feed operations are changed to
multi-copy oprations during DPCM reduction copy
4
operations, residual images of page one appear from the
second copy onward. (This problem occurs for copy
paper sizes of A4 or greater.)
Even though the rear edge void has been set during
simulation 26-20, when multi-manual feedoperations are
5
carried out for DPCM the rear edge void operations
cannot be carried out for the second page.
The interrupt key is not acknowledged after the
preliminary paper feeding operation has been completed
6
during single manual feed operations.
When single manual feed copy operations are carried out
after the interrupt key has been depressed and the
machine has been put in the interrupt mode, and if the
7
interrupt key is then depressed once again during these
copy operations the settings from before the interrupt
mode was set are not reset.
The counter values remain in the single count mode even
though A3 copy operations are carried out after the
8
cassette detection setting has been set to “extra”.
There is no rear edge void for page two original
9
document copies when multi-manual feed copy
operations are carried out using the ADF.
The original document remaining lamp continues to flash
when copy operations are halted (due to copy paper
running out or jams, etc.) while the machine is in OC
10
mode, even though the original document has been
removed from on top of the platen and placed in the
ADF. (This problem includes the DPCM mode.)
If OC mode or DPCM copy operations are carried out
during interrupt mode and a copy operation halt occurs,
the original document remaining lamp does not flash
11
when the interrupt mode is terminated by depressing the
interrupt key.
When an original document is set in the ADF and the
interrupt key is depressed after ADF copy operations
12
have finished, interrupt reserve mode is set.
When the copy count setting is carried out after the clear
key is depressed and the copy operations are halted
13
during DPCM page two copy operations, and the copy
operations are then resumed, the copy operations start
up from page two.
maximum velue (exposure level 1.0).
This trouble occurs when the original document size
changes during copy operations but the copy paper tray
does not change accordingly.
→ A change has been carried out so that when the
original document size changes during AMS or manual
copy operations, the illumination timing of the blank lamp
is reset from the new size of the original document.
This problem occurs when simulation 41-1 is carried out
once the original document size is detected after placing
it on the platen. A correction has been carried out so that
the original document size data is cleared when the
execution of simulation 41-1 is started.
Problem of copies with residual images are alleviated by
correcting the ON timing for the grid bias and the blank
lamp illumination timing for the second copy onward of
page one.
This problem has been alleviated by correcting the
illumination timing of the blank lamp so that the rear edge
void operations can be carried out on the second page.
This problem has been alleviated by carrying out a
correction on the program so that the interrupt key will be
acknowledged during single manual feed operations.
(The machine status will be interrupt reserved.)
This problem has been alleviated by carrying out a
correction on the program so that the settings before the
interrupt mode is set and the settings after the interrupt
key is depressed during single manual feed copy
operations are all returned to their original settings.
This problem has been alleviated by changing the
program so that normal copy paper size run detection is
carried out even though the copy paper cassette size has
been set to “extra”, and a double count is registered for
A3 and WLT sizes.
This problem has been alleviated by changing the
program so that rear edge voids are possible for page
two and after during original document copy operations.
ADF copy operations are permitted if an original
document is set in the ADF after the ADF cover has been
opened and closed one time when the OC copy
operations have been halted. (The program has been
corrected so that the original document remaining lamp
does not flash.)
This problem occurs when the copy status before the
interrupt mode was set was such that the copy paper ran
out or a problem such as a jam occurred while the copy
operations were in progress. This problem has been
alleviated by changing the program so that the original
document remaining lamp flashes when the interrupt
mode is terminated.
This problem has been alleviated by changing the
program so that the machine is put into the interrupt
mode when the interrupt key is depressed after copy
operations have been completed.
This problem has been alleviated by changing the
program so that the copy operations start up from page
one after DPCM copy operations have been halted.

Multi copy page count settings cannot be carried out
when the ADF mode is changed to OC mode after copy
14
operations are halted during an ADF copy multi-0 page
count.
The main motor continues to run after the ADF cover is
opened once the last page has been delivered during
15
ADF copy operations with original document stream
mode settings.
When the copy button is depressed and the 1 set 2 copy
lamp is off after copy operations have been terminated
16
by depressing the ca key during DPCM copy operations,
the DPCM copy operations are resumed.
When an original document is set in the ADF after DPCM
copy operations have been halted, the original document
17
remaining lamp flashes.
The original document size indication remains on after
copy size settings are carried out by overseas original
document size input operations, even if the interrupt
18
mode is set. Furthermore, after the interrupt mode is
terminated the original document size indication does not
return to its original status before the interrupt mode was
set.
When the clear key is depressed while the ADF final
original document copy operations are in progress and
19
an original document is set in the original document tray
while the machine is operating, the ADF mode cannot be
set even if copy operations have finished.
Simulation 46-2 (easy exposure adjustments) has been
changed to 70-12.
20
Toner scattering measures are not carried out until 5K
copies have passed after developer replacement
operations have been carried out.
21
The copy reduction/enlargement percentage does not
return to 100% when the interrupt key is depressed and
22
the machine is set to interrupt mode during OC mode
AMS ON reduction/enlargement copy operations for
Swallow-B domestic bound machines.
OC original document detection does not take place after
the machine is halted due to the copy paper running out
23
(P display) during multi-manual paper feed copy
operations. (The original document size display does not
change.)
When the interrupt mode is set during APS copy
operations with the AMS set to OFF, and the cassette
selection key is depressed, the copy paper cassette tray
changes. After the interrupt mode is terminated,
24
however the copy paper cassette tray setting is different
than before the interrupt mode was set. Before, when the
APS is OFF before the interrupt mode was set, the
cassette selection setting was not returned to its original
status once the interrupt mode was terminated.
This problem has been alleviated by changing the
program so that the multi page count input is allowed
when the copy operations have been halted.
This problem has been alleviated by changing the
program so that the stream mode is terminated and copy
operations are finished when the ADF cover is opened
after the last page has been delivered.
This problem has been alleviated by changing the
program so that the DPCM is cleared when the CA key is
depressed and copy operations are halted.
This problem has been alleviated by changing the
program so that the original document remaining lamp
does not flash when an original document is set in the
ADF after DPCM copy operations have been halted.
This problem has been alleviated by changing the
program so that the original document size indication is
extinguished when the interrupt mode is set. The original
document size from before the interrupt mode was set is
remembered, and once the interrupt mode is terminated
the original document size indication from before the
interrupt mode was set is once again displayed.
This problem has been alleviated by changing the
program so that the ADF mode is set.
Because this simulation is only used during production
operations, it has been set to the 70 series. (Simulation
setting changes take place only when the % key, the
EXP key or the CA key are depressed. When the copy
button is depressed the EXP 5.0 value calculation is
carried out in addition to the setting value registration.)
As a measure for toner scattering, toner concentration
correction value is lowered to a maximum of 10 when the
power supply is turned ON and the fusing temperature is
O
C, or when the main motor is turned OFF for
below 80
more than 5 hours. However, problem arise when the
power supply is turned OFF except during copy
operations, the appropriate toner concentration is already
lowered, preventing the proper toner concentration.
Before the APS commenced without the
reduction/enlargement percentage being returned to
100%. This problem has been alleviated by changing the
program so that the APS settings are carried out after the
reduction/enlargement percentage is returned to 100%.
This problem has been alleviated by correcting the
program so that the original document detection is once
again carried out when the multi-manual paper feed copy
operations are halted due to the copy paper running out.
This problem has been alleviated by changing the
program so that when the APS is ON before the interrupt
mode was set, the cassette selection setting is carried
out automatically. When the APS is OFF before the
interrupt mode is set, the cassette selection setting is
returned to its original.
