- 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.

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.

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. The ROM part number is also A153-5109.

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.

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

PAGE: 2 of 4

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.

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?

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.

White lines/bands appear on the copy image. In almost all of these cases, the image density is low in the lines/bands, so these areas are not as dark.

CHARGE ROLLER CLEANING PAD

CLEANING BLADE

DRUM

Revision of service manual Information only Other

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 marks is designed to reduce the pressure applied to the originals by replacing the entrance guide stopper spring with a new one. This change also results in a decrease in the amount of force used to feed the original and may create an original non-feed problem. Therefore, the separation bracket has been modified to reduce the angle by 2 degrees.

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.

Problem: The drum becomes dirty with glue.

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.

Countermeasure:

A mylar has been added on the upper transfer entrance guide, and the transfer guide plate has been modified by raising the height of its ribs to alter the angle in which the paper enters. See the illustrations below.

SYMPTOM

The drum becomes covered with a black substance, most likely toner, after 8K to 20K copies. The surface of the drum seems to be coated with 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

The additives contained in the acid paper called talc (MgO SiO2) cause the filming problem.

Mechanism

The talc characteristics make it negat ively polarized. The talc powder is electrostatically attracted to the positively polarized toner and adheres to the drum surface in non-image areas. Once on the drum, the toner/ talc mixture is pressed down by the transfer belt and charge roller, leading to a gradual build-up on the drum surf ace. The talc on the drum surface is carried to the development unit and accumulates there. This accumulation of talc accelerates the filming problem in an area the width of the development roller.

SYMPTOM

The add toner indicator is displayed because the toner bottle does not fit in the machine. The toner supply unit is too tight to be closed properly.

CAUSE

Toner accumulates in the bottle stopper area and the toner slider is blocked by the accumulated toner. Alternatively, the chuck shaft itself is broken.

The toner accumulation and chuck shaft breakage mechanism is as follows:

Bottle Unit Closed

Once the bottle is opened, there is a space between the toner bottle stopper and the slider which allows toner to accumulate in the bottle stopper area. Normally, the amount of toner that passes through this space is very low but if the bottle unit is repeatedly opened and closed (to remove paper jams, etc.), the toner accumulation continues to increase. When the toner accumulation in the bottle stopper area reaches a certain level, this interferes with the movement of the slider. This results in excessive force being applied on the chuck shaft when the bottle holder is closed.

SYMPTOM

There is a bend (wrapping) on the leading edge of the original the same size as the width of the separation belt. If the bend in the original is large, dirty background may appear on the copy in the area that corresponds with that bend.

Note: This phenomenon occurs more often if the original has an upward curl. Originals output from laser printers are particularly susceptible.

CAUSE

The problem occurs as a result of the contact between the edge of the original and the separation belt when the original is fed to the exposure glass. If the upward curl of the original is large or the cut in the leading edge of the paper is not smooth, this problem is more likely to occur.

Small: Good for original leading edge bending, marginal for double-sheet feeds.

The Separation Belt Tension also affects the angle

Strong: If the tension is strong, the angle is relatively large.

SOLUTION

This problem can be resolved by reducing the angle of the belt, which will help original entrance, or by lowering the guide mylar by 1 mm to reduce the resistance of the original. Change the separation belt bracket (A5481291: #20 in the diagram on the right) and the spring to reduce the angle between the original and the belt and also decrease the force from the belt on the edge of the original. Replacement Part Number: A5489504

Note: If jams occur due to double-sheet feeds, please install the stronger pressure spring packed with the machine. This measure is designed to facilitate the entrance of the originals. However, if the friction between the originals is high, and the originals are large, double-sheet feeds may occur if many originals are used at the same time.

If thin originals are used after the stronger pressure spring has been installed, they may become creased. If so, please reinstall the original pressure spring and reduce the number of originals used at one time.

The modified brackets shown above can also be used in the DF64.

Offset / Paper jam in the fusing unit

Part information Electrical Transmit/receive

Action required Service manual revision Retrofit information

S.Hizen

SYMPTOM

 Paper misfeed in the fusing unit (accordion-style paper jam)  Offset image

CAUSE

Toner adheres to the hot roller in a shorter period than the hot roller replacement interval, when paper with a lot of paper dust is used. If the amount of paper dust is higher, the meter reading at the time that toner adheres to the hot roller is lower.

The following items also have an affect on the amount of toner accumulated on the hot roller.

1. Sky shot copying is one of the main causes of the toner adhesion.

2. Light copy / Half tone copy: The toner in the light copy or half tone image is unstable in the fusing process.

3. Transfer belt cleaning malfunction

4. Other factors: Please refer to the items listed in RTB-7

SOLUTION

Hot roller cleaning using HR cleaner in the early stages of toner adhesion on the hot roller. The HR Cleaner P/N # A153-9530 is available as a service part.

Cleaning Procedure:

Check the hot roller during every visit to the customer. If the luster of the hot roller surface fades, toner starts adhering to the roller and the roller

needs to be cleaned at this stage. Otherwise, it will be hard to clean away the toner adhesion on the roller once it reaches the level that offset image occurs.

Pull out the fusing unit from the machine, open the exit cover and wipe the toner off (especially from lusterless parts) while the fusing unit is still warm. Be careful not to touch the hot part of the unit with a bare hand.

Cleaning Blade Flip

QAC 1st Field Information Dept.

Troubleshooting Mechanical Paper path Other ( )

Part information Electrical Transmit/receive

Prepared by:

Action required Service manual revision Retrofit information

S.Hizen

SYMPTOM

Noise and blank copies due to cleaning blade flip. Sometimes the drum drive belt comes off because the drum locks up as a result of the

flipped blade.

CAUSE/SOLUTION

The friction between the drum and cleaning blade has become high.

1. The amount of setting powder is too low when the blade is replaced. The setting powder should be applied on the both blade edge and drum surface so that the drum surface appears white when the machine is installed or the blade is replaced.

2. The amount of toner that comes into the gap between the drum and cleaning blade

is too low when a lot of small size lengthwise copies are made. About an inch (a couple of centimeters) at both ends of the cleaning blade has been coated to prevent the blade flipping in this kind of case, due to a machine operation that is hard to control. The coated cleaning blade is the same part number as the non-coated one. The only way to identify the blade is the lot number printed on the blade. The starting lot number of the coated blade is

731XXXXX onward.

NOTE:

In addition to the above, if glue or something glue-like adheres to the surface of the drum, similar symptoms may appear. Therefore, when the blade flipping occurs, please check the drum surface carefully to identify the possible cause. The glue material adhered to the drum can be removed by wiping using a cloth and isopropyl alcohol.

Use of alcohol may cause temporary occurrence of uneven density on copies, but this soon disappears. Make sure the drum is dry before reinstallation to avoid possible toner adhesion.

SYMPTOM

1. During paper feed from the duplex unit, the leading edge of the paper is bent or a nofeed jam occurs.

2. During stacking in the duplex unit, a stacking jam occurs.

ACTION

1. Paper feed jam (leading edge bent or non-feed)

1) Check to see if the duplex guide plate mylar (A1344662) is set properly. If it is bent

or out of position, please replace the duplex guide plate. Method: Rotate the feed roller by hand. If it makes a clicking sound it is OK. (If the mylar is bent or out of position, the leading edge of the copy may be bent or no-feed jams may occur.) Reattaching the mylar (as shown below) is a temporary countermeasure. As a permanent countermeasure, the duplex guide plate should be replaced.
