- ADS Pattern Detection and ADS Correction -

If the user selects Auto Image Density (ADS) mode, the machine
monitors the output from the ADS sensor and adjusts the
development bias to compensate for variations in ADS sensor
response. This prevents dirty background.

Every 1,000 copies, the machine calibrates the ADS sensor output by
reading the ADS pattern under the left scale of the exposure glass.

The ADS sensor must also be recalibrated:

• If the drum is changed

• If the ID sensor is cleaned or changed

• If the exposure lamp or optics are cleaned or changed.

MODEL:

Continuous Supply of power to the Jogger Motor

1. Phenomeno n:
The Jogger Motor is continuously supplied with power but does not rotate which
leads to the deformation of the mold around the duplex unit. SC525 may be
indicated for the Duplex Copy Mode because the Jogger Motor is not rotating. A
continuous supply of power will result in overheating of the Jogger Motor.

2. Possible Causes:
When the Jogger Motor is operating, if there is a drop in voltage of 5v, the ISP may
malfunction, and as a result two phases of the motor will continue to be supplied
with power.

Phoenix

Main Board

ISPCPUPSU

DRIVER

M

3. Countermeasure and Field Action :
We will change the software so that the Jogger Motor power will automatically shut
off if any of the phases of the motor runs continuously for 3 minutes or longer. The
ROM part number with this program is A153-5109. If this problem occurs, the
stepping motor part of the duplex tray may be deformed by the heat generated. We
would appreciate it if you would replace the whole duplex tray and also install the
ROM A153-5109 at that time.

Additional Information: The implementation of the modified ROM is planned for the
middle of July for the mass-production units. We would like to emphasize that the
occurrence ratio of this problem is very low.

Technical Bulletin No. RTB-006

SUBJECT: • Continuous Supply of power to the Jogger Motor

• Developer Leakage

Developer Leakage

1. Problem:
The main motor, charge roller, transfer belt and development unit are continuously
in the ON condition. This results in developer leakage from the development unit
and ultimately leads to blank copies because of a shortage of developer.

h In this case, the leaked developer accumulates in the transfer unit. Accumulation

in the rear of the development unit may indicate wear on the paddle roller shaft
caused by developer as a result of the improper placement of the V-ring, and could
necessitate replacement of the unit. There have only been a few isolated cases
reported worldwide connected with the V-ring placement and we do not anticipate
more occurrences.

2. Conditions leading to the Occurrence:
This problem may occur when the timing of the Pre-start signal and the ADS
Density signal are sent at approximately the same time when the machine is set in
the following conditions: ADS Mode, Special Paper Feed Tray (see the attached
table for details), Special CPM (see the attached table for details), 1st copy after
start-up (Including the 1st copy after the completion of the second feed in the duplex
mode), or when the copy count is 1 to N.

DATE: May 15, ’96
PAGE: 2 of 4

3. Cause:
The Pre-Start signal for the software’s engine control area is erased by the ADS
Density signal.
Normal:
ADS Density signal sent signal received ADS Density signal processed
PreStart signal sent signal received PreStart signal processed
Abnormal:
PreStart signal sent signal received ADS signal sent
signal received ADS signal processed.

h In this case, the final processing of the PreStart signal is not completed. The

control based on the image trailing edge signal of the engine control area stops
working properly and as a result the main motor, charge roller, transfer belt and
development unit remain ON.

4. Countermeasure:
We will change the software by inserting a signal processing function prior to the
signal receipt that is activated when the ADS Density signal is sent. As a result, the
abnormal signal route will be changed in the following manner.
PreStart signal sent signal received ADS Density signal sent
PreStart signal processed signal received ADS Density signal processed.

Identification of and Measures for Fusing Offset

By employing the proper procedures in the field, the Offset problems reported there
may be prevented. When an offset problem occurs, it is very important to correctly
isolate the cause and utilize proper measures to solve the problem. Hence, we have
compiled a list of the types of offset often encountered in the field, methods to
identify the offset and measures to be taken. This list is arranged in the following
manner: A. Offset problems related to Fusing B. Phenomena mistaken for Offset.
Each symptom presented lists causes and the measures to be taken.

A. Cases of Offset related to Fusing

1. Hot Offset (excessive fusing)
After consecutive paper feeds, periodic offsets occur (125mm pitch). Similar
problems are sometimes found when using comparatively thin paper.
Cause/Measure:

• Check the fusing temperature. Is it set too high? The maximum is 190°C.

• Is the thermistor coming in contact with the roller? Confirm that the roller comes

in firm contact with the thermistor. Check for deformation of the thermistor unit.

• Is the thickness of the paper within specifications? Standards 52~157g/m2,

14~42lbs.

h

Confirm the implementation of the anti-rise countermeasure for the thermistor.

2. Cold Offset (incomplete fusing)
Offset (125mm pitch) only occurs in the morning when the machine is first turned on
or when using thick paper.
Cause/Measure:

• Low temperature environment? In conditions under 10°C and 15% humidity, prob-
lems may occur when the machine is turned on at the beginning of the day.

• Is the temperature adjusted to the proper setting? Is it set too low? The minimum is
160°C.

• Has there been a drop in voltage? Is it below 90v? In this case, the nip area should
be increased and the temperature setting should be raised.

3. Electrostatic Offset
When using OHPs or laminated paper, offsets appear scattered around the
characters.
Cause/Measure:

• Are the fusing roller and pressure roller properly grounded? Make sure that the
quenching brush on the back of the rollers is touching both the fusing and pressure
rollers.

• Is the fusing entrance guide board properly grounded? Make sure that the quenching
brush behind the unit fusing stay and the fusing entrance guide are connected when
the fusing unit is in place.

• What is the environment like? In conditions below 10°C and 15% humidity, certain
types of paper are prone to electrostatic offset.

Though certain types of paper may be subject to this condition, occurrences are quite

rare so this should not occur under normal operating conditions.

Hot and Pressure
Rollers.

PAGE: 3 of 4

4. Insufficient Cleaning Offset
Irregular occurrences, falls off when wiped by hand. Occurs over the whole surface,
large amounts involved.

• Inadequate cleaning of the pressure roller leads to residue on the pressure roller. This

reduces the lifetime of the pressure roller, and premature replacement is necessary.

• Is the cleaning roller attached?

• Is the cleaning roller rotating properly?

• Is there an uneven build up of toner?

If any of these symptoms apply, replace the cleaning roller. However, if there is
toner accumulation of about 0.5mm near the cleaning roller, the cleaning efficiency
has dropped and indicates that the roller should be replaced. If the accumulation is
less than 0.5 mm, then the chances that this roller is the cause of the problem are

very slight.

5. A narrow horizontal black line, not on the original, appears on the copy 125mm from
the front edge or it continues at a 125mm pitch.
Cause:

No blank areas on the leading and/or trailing edges.

Measure:

Blank areas should be created at both the leading and trailing edges. (This only
occurs when the blank areas are 0mm)

6. The offset picture and characters are inverted. (When using the back of the sheet, the
image aligns with the one on the other side.)
Cause:

The melting point of the toner of the image on the back of the sheet is too low.

Measure:

If the melting point of the toner is too low, stop the use of the back of the sheets.
Examples of toners with low melting points: Flash fusing , color copier,
hot transfer ribbons.

7. Irregular occurrences, falls off when wiped by hand. Related to the position of the
thermistor.
Cause/Measure:

• Toner debris accumulated on the thermistor. Caused by a dirty thermistor. Clean the

thermistor.

8. Frequent Offset; Toner accumulation on the fusing roller Cause/Measure:
Conditions 1~7 listed above did not continue?

• Abnormal Image Condition (drop in density, defective drum cleaning, defective trans­fer cleaning, etc.) did not continue?

• Was the total number of copies made while the machine was in use extremely high
or low?

• Is the toner a Ricoh product?

• Is the fusing roller a Ricoh product?

• Is the pressure roller a Ricoh product?

h

Some types of paper may be the cause of the problem when offset continues on

some machines. Please contact us if this is the case.

B. Phenomena mistaken for Offset

1. The offset drawings and characters are inverted (Aligned with the image on the back
of the original)
Cause: The back of the original was copied.

2. The offset pitch is 188.5mm
Cause: Scratched drum Replace the drum

3. Irregular Occurrences, Fused Image
Cause: Defective drum cleaning Confirm that the parts around the drum are
functioning properly (cleaning blade, etc.)

4. Images on the surface unrelated to the original, lines appear parallel to the paper
feed direction.
Cause: Defective drum cleaning, scratched drum, uneven lighting from the exposure
lamp Inspect the parts around the drum (cleaning blade, etc.) Check for uneven
lighting level

5. Lines appear on the back of the copy parallel to the paper feed direction.
Cause: Defective transfer belt cleaning, toner scattering in the machine
Check the transfer unit, cleaning blade. Toner scattering may occur because the
toner density is too high, so the Process Control Conditions should be checked.

Revision of service manual

Cause/Mechanism:

The amount of electrical charge on the drum is
low due to toner accumulation on the charge
roller. This decreases the charge ability. The
toner remains on the drum after it passes under
the cleaning blade and adheres to the charge
roller. The amount of toner remaining on the
drum exceeds the amount that can be cleaned
off by the charge roller cleaning pad, leading to
toner accumulation on the charge roller. The
toner accumulation level on the charge roller is
directly related to the cleaning ability of the
cleaning blade. As a result of the accumulation,
the charge ability decreases due to the toner
accumulation and leads to the white (lighter)
lines/bands on the copy.

The countermeasure for the dirty background is as follows. This countermeasure is for
those machines that are installed in places with a lot of dust and have had many
service calls related to dirty background. Be sure that you check the optics cavity
because an external examination of the machine may be deceptive.

Possible Causes:

1. Low copy volume machines
The lamp voltage correction/compensation by the process control every 1K copies
cannot catch up with the lamp voltage level necessary to eliminate the dirty
background.

2. High copy volume machines
The lamp voltage increases to the maximum level, and the voltage cannot rise high
enough to create the light intensity necessary to eliminate the dirty background.

Falcon/Swallow: More than 600 copies
If you install the optics filters on a machine which the customer may make
continuous runs which exceed the conditions set above, please set the
copy limit with SP5-017 to the maximum numbers. This is because the
temperature of the exposure glass may be much higher if the lamp voltage
has already reached the maximum level to compensate for the image

Possible Cause:

Glue can be transferred to the drum surface when adhesive paper is used.
Sometimes the glue stuck on the drum surface transfers to the entrance seal on the
development unit when the drum rotates in reverse. This results in the deformation of
the entrance seal on the development unit.

SYMPTOM

The drum becomes covered with a black substance, most likely toner, after 8K to 20K
copies. The surface of the drum looks as if is being coated by toner across a width equal
to that of the paper or the development roller. As a result, dirty background appears all
over the copy.

CAUSE

An additive in acidic paper called talc (MgO SiO2) causes the filming problem.
The characteristics of talc make it negatively charged. The talc is electrically combined

with the positively charged toner and adheres to the drum surface in the non-image areas.
Once on the drum, the toner and talc compound is pressed down by the transfer belt and
charge roller, leading to a gradual build-up on the drum surface. The talc on the drum
surface is carried to the development unit and then accumulates there. This accumulation
of talc accelerates the filming problem in an area across the width of the development
roller.

Coated with toner

SOLUTION

Charge the type of paper used from an acidic type to a neutral type. The type of paper
can be checked in the following manner.

1. Use the testing pen. (The part number will be available soon.)

2. Burn a piece of the paper and check the color of the paper ash.

Black →acidic type
Gray/white →neutral type

NOTE: Once this problem occurs, the drum and developer in the development unit need

to be replaced and the transfer belt needs to be cleaned.
