1. PHENOMENON
This problem occurs only on the sorter stapler with the F22.
The final copy stops at the exit sensor of the sorter stapler in normal copy mode (without
sort/stack mode). When this happens, the jam indicator fails to blink.
The occurence ratio is low because this problem occurs only under the following conditions:
1) Paper with insufficient stiffness is used.
2) The sorter stapler exit sensor bounces.

2. CAUSE
The exit sensor feeler tends to bounce when the paper is passing the feeler, and the
sensor briefly turns off.
The CPU of the sorter stapler mistakenly recognizes that the paper has exited into the tray.
Consequently, sorter stapler motor stops before the paper exits completely. (The motor
stops 0.3s after the exit sensor turns off.)

1. Summary
SC - 1 cannot be cancelled by pressing the SC reset button. This prevents the customer
from just by passing a potentially serious problem. However, when SC - 1 occurs as a
result of electrical noise or some other electrical error, the service representative has to
visit the customer’s office and reset the machine.
We modified the software of the main ROMs so that SC - 1 is less likely to be triggered
by electrical noise.
2. Contents of the modification
If the main board detects an abnormal signal from the lamp regulator lasting 5 ms or
longer, SC - 1 is displayed. The new software extends this detection time from 5 ms to
15 ms, and this reduces occurence ration of the aforementioned problem.

Description Current Tungsten Corona P/N
FROM:Copier Technical Support Section
MODEL: F22
The platinum and the tungsten corona wires are fairly similar in performance and handling;
however, there are the following differences:
Point 1
During the copy cycle, less foreign matter (toner, dust, gas) will build up on the surface of
a platinum corona wire than on a tungsten wire. Consequently, platinum corona wires do
not need to be cleaned as often to maintain copy quality. This is true for both these
platinum corona wires and the third vendor’s platinum corona wires.
Point 2
Negative charges cause portions of the surface of a platinum corona wire to break off,
affecting the copy image and requiring replacement of the wire. A platinum wire cannot be
used as a negative charge corona. (A tungsten wire can be used as a negative charge
corona wire.) This is true for both these platinum corona wires and the third vendor’s
platinum corona wires.

SUBJECT: Platinum Corona Wire DATE: Apr. 15, ’91

--When to install the platinum corona wires-
The platinum corona wires do not have to be cleaned as often as the tungsten wires
(point 1). For this reason, the platinum corona wires are most suitable in cases where a
machine is installed in a relatively inaccessible location (far from a service center) and
service calls are difficult to make.

1. Summary
After installation, the F22 would sometimes produce blank copies during multiple copying.
We issued RTB-004 (F22) to solve this problem, but we have had reports from affiliated
companies that some machines still sometimes produce blank copies, even after following
the procedure outline in the RTB. Also, we’ve had reports that paper jammed in the
machine because of scanner movement. Here are additional steps to solve these
problems:
2. Adjustments
(1) If the RTB-004 procedure doesn’t fix the paper jam and/or the blank copy problem,
change the SP31 data (scanner brake timing). Change the data from the factory
setting of 8 to the new setting A.

(2) After changing the SP31 data, the copy image registration may change. Check the
copy image and if necessary, adjust the copy image registration with SP32.
3. SP31 factory setting
We now set SP31 to "A" when the machines leave the factory. We’ve put the new setting
beginning with the machines listed in the table below.

4. Cause of the problem
When making repeat copies, the scanner first has to return to its home position, and it has
to return before the start of the next copy cycle. If it doesn’t, the paper will be fed, but the
scanner won’t be in time, the lamp will not turn on, and the copy process timing will go
out of control causing a blank copy and possibly a paper jam.
To prevent these problems, decrease the total scanning time with SP31.

Scanner H.P. is

SP31 controls the start position of the first scanner. If we lower the setting, for instance
from 8 to 7, the scanner shifts about 2 mm (0.079 inch) away from the scanner H.P.
sensor. This increases the total scanning time.
On the other hand, if we raise the setting, say from 8 to A, the first scanner shifts about 4
mm (0.158 inch) closer to the H.P. sensor. This will decrease the total scanning time.

1. Summary
We have received some reports of this problem and have encountered independently as
well. So, we have modified the software in the main ROM on the main PCB to solve the
following items,
1) Computer Form is not fed in the CFF mode.
2) Originals are not fed in the user program mode.
3) Jitter image appears on the trailing edge of A4 or Letter size in full size mode.
2. Details
1) CFF mode does not work
Problem
When the computer form paper is set on the exposure glass, the DF cover is lowered and
the start key is pressed, one copy is made but the computer form paper is not fed at all.
Cause
The main PCB cannot get the CFF set signal due to noise.
Countermeasure
When a computer form is set in the computer form feeder and the DF cover is lowered,
the main PCB checks the CFF set signal only once. To ensure detection of set signal, we
have modified the software to check the CFF set signal twice.
Page 26
Technical Bulletin No. RTB-012
SUBJECT: Software quality improvement DATE: July 31, ’91
PAGE: 2 of 4
2) Originals are not fed in the user program mode
Problem
Originals are not fed when these steps are followed in this order:
1. Insert originals into the document feeder.
2. Recall one of the program numbers (1 to 5).
3. Enter the number of copies required.
4. Press the start key.
Cause
In the present software for program mode, not only copy modes except copy number but
also DF or platen mode are stored. (When originals are in the feed-in unit of the DF while
storing the user program, the DF mode is stored. On the other hand, when originals are
not in the feed-in unit of the DF while storing the user program, the platen mode is stored.)
In many cases, the above key operation will result in platen mode copy due to this reason.
Countermeasure
The software for program mode has been changed, so that DF or platen mode could not
be stored.
NOTE: To prevent this mode without the ROM replacement, please instract the customer
as follows:
First, press the recall key and enter the number of copies. And, then set the
original to the DF.

3) Jitter image
Problem
2 or 3 mm band jitter image may appear on the trailing edge of A4/Letter size paper.
Feed
Trailing Edge
Normally, this band is erased by the trailing edge erase function. However, if the width of
the erase area is narrow, the jitter image appears.
Cause
The scanner speed of this machine is higher than that of the F21, F20. If the scanner
movement is slightly heavy, the scanner will start braking within the image area.
Countermeasure
The scanner brake timing has been delayed 3 mm at the trailing edge. So, A4/letter image
is completely scanned.
In RTB-F22-010, we informed you of how to use SP31 (Scanner brake timing) and that the
data setting "A" has been set at the factory. So, do not change the data "A". If the data "A"
is chaged to "9" or "8", blank copies or paper jams may occur easily.
Jitter image
2 ∼ 3 mm
NOTE: Make sure that SP31 data is set at "A", since scanning time is increased due to
this new program.
If "9" or smaller data is set, blank copy or paper jam will occure.
If "B" or greater data is set, jitter is observed at the leading edge of copy.

2) Toner marks
Problem
After multi-copying for a long time, toner marks appear at the position where the pick-off
pawls are located.
Cause
During A4/LT or smaller size multi-copy runs, the pick-off pawls continuously touch the
drum, and the toner around the drum accumulates on the pick-off pawls. After many
copies (depending on the copy image) the toner on the pawls drops on the paper.
On the other hand, when A3 (DLT) paper is used, the pick-off pawls are repeatedly
turned off and on, and the toner will not accumulate on the pawls.

than time "B + C", the pick-off pawls solenoid cannot be turned off. The time "C" is higher
priority than time "B". So, time "B" is cancelled, in this case.
To turn the pick-off pawls solenoid on and off repeatedly, "A" should be 50 ms longer than

1. Summary
We have received some reports of the following software problems and have encountered
it independently as well. So, we have modified the software in the main ROM on the main
PCB:
1) Incorrect erasing at 103% enlargement on Letter size ( 8.5"x11") copies
2) Toner end operation
3) Void area on the leading edge of 11"x17" size copy
2. Details
1) Incorrect erasing at 103% enlargement on Letter size ( 8.5"x11") copies
Problem
For the 220-240V version machine, when enlarging to 103% on letter size copies, half of
the copy image is missing.
Cause
Only for 103% enlargements on letter size copies, the erase lamp erases half of the copy
image. This is a software error.
Countermeasure
The software has been modified.
2) Toner end operation
Problem
Even if the toner end indicator is lit, the machine can be operated immediately by just
turning the main switch off and on. After making a few hundred copies in this condition, the
carrier will be damaged due to too low toner concentration.
Countermeasure
The toner end operation has been changed as follows:
When the toner end indicator is lit and the main switch is turned off and on, the machine
goes in the toner supplying mode ( toner supply clutch and development motor on) for 40
sec. After that, the print key becomes green. We supposed that the operator would replace
the toner cartridge with a new one, because the operator has to wait 40 sec after turning
the main switch off and on in the toner end condition.

3) Void area on the leading edge of 11"x17" size copy
Problem
Void area appears on place 110mm from the leading edge of 11"x17" size copy.
Cause
The paper buckle is little larger than the specification when the paper is fed from the 1st
tray, the 2nd tray, and the duplex tray. So, the copy paper has a wrinkle at the place
mentioned above.
Countermeasure
The paper buckle is decreased as follows:
The paper from the duplex tray: minus 3.0mm
The paper from the 1st feed tray: minus 2.1mm
The paper from the 2nd feed tray: minus 1.7mm
The paper from the large capacity tray: same as before
