General Information

The OL400e, OL410e, and the OL410e/PS are compact Light Emitting Diode (LED) page printers. The printers utilize an LED head for the exposure method. Dry electrophotography is used as the development method. The print resolution is 300 x 300 dots per inch. The OL410e and the OL410e/PS (in PCL Mode) can print at 300 x 1200 dots per inch. The printers have a continuous print speed of up to 4 sheets per minute.

All three products include both a Centronics parallel interface and a 9-pin RS232 serial interface as standard features. The OL410e/PS includes an LocalTalk interface, which can only be used in PostScript mode. Theprinters have automatic interface switching capabilities, a power-saving standby mode, free-paper sizing (which allows printing on custom size paper), and graphic compression capabilities (for full-page business graphics).

The OL400e utilizes 512 Kbyte of standard Random Access Memory (RAM). An optional expansion memory board can be installed. Up to 4 Mbyte of RAM (in 1 Mbyte increments) can be installed on the expansion board, providing up to 4.5 Mbyte of total RAM in the OL400e.

The OL410e utilizes 2 Mbyte of standard Random Access Memory (RAM). The main controller board contains 1 Mbyte of RAM. The standard expanded memory board contains 1 Mbyte.

An optional expansion memory board can be installed in place of the standard expanded memory board. The optional board contains 2 Mbyte of RAM. However, up to 4 Mbyte of RAM (in 1 Mbyte increments) can be installed, providing up to 5 Mbyte of total RAM in the OL410e.

The OL410e/PS utilizes 2 Mbyte of standard Random Access Memory (RAM). 1 Mbyte is on the main control board. 1 Mbyte is on the PostScript Board. The PostScript board will accept and additional 3 Mbytes of RAM, providing up to 5 Mbyte of total RAM in the OL410e/PS.

Print Operation

Print Operation

Both the control function (data reception and bit-image data generation) and the print engine function (LED head, registration motor, and drum motor) are integrated. Both functions are controlled by the main controller board. The peripheral logic is integrated into one chip, an ASIC microcomputer (RISC-based microprocessor) chip.

Data is received through either the Centronics parallel interface or the RS232 serial interface.

These two interfaces are located on the main control board.

The LocalTalk interface is located on the PostScript Board.

The data is then stored in the receive buffer. The data is transferred from the receive buffer to a processing section of the main controller. In this processing section, control codes and printing codes are assigned. Once the font is determined, the data is written to the page buffer.

The microprocessor then executes the print routine. The data is extracted from the page buffer, synchronized to the printing operation, and written to the band buffer. While performing the engine functions, the microprocessor sends the data from the band buffer to the LED array head.

2.3.01 Basic Principals - Electrostatic Printing

2.3.01 Basic Principals - Electrostatic Printing

A -1.3 Kvdc charge is placed on the charge roller. The charge roller is in direct contact with the surface of the image drum. The printer engine section enables the LED array in conformance with the data received from the host via the interface on the main controller board. Once the charged drum is exposed to this light, an electrostatic image is formed on the drum surface. This latent image is developed with toner.

Charging

The surface of the image drum is uniformly negatively charged by the application of a negative

charge to the charge roller.

Exposure

Light emitted from the LED head irradiates the negatively charged surface of the image drum.

The electrostatic potential of the irradiated part of the image drum surface is lowered, so that an electrostatic latent image associated with the print image is formed.

Developing

When the negatively charged toner is brought into contact with the image drum surface, it is attracted to the electrostatic latent image by static electricity, making the latent image visible.

At the same time, the residual toner on the image drum is attracted to the developing roller by static electricity.

Transfer

OL400/410ex (96-01-30)

Paper is placed over the image drum surface. A positive charge (opposite in polarity to the toner) is applied to the reverse side of the paper by the transfer roller. The toner is attracted by the positive charge. The image formed on the image drum is transferred to the paper.

Cleaning

The toner remaining on the image drum after transfer is temporarily attracted to the cleaning roller by static electricity. This residual toner is accumulated in the image drum cartridge until the drum is replaced.

Fusing

The toner image transferred to the paper is fused to the paper by heat and pressure.

OL400/410ex (96-01-30)

2.3.02 Engine Functions

2.3.02 Engine Functions

The engine control section of the microprocessor on the main controller board enables the fuser lamp and activates the preliminary print circuits. Upon completion of the preliminary print functions, the engine control section enables the LED array in conformance with the signals received from the host, and commands output from the control section of the

CPU. The LED illuminates, leaving a latent image on the photosensitive drum. The engine control section also controls paper feed, paper transfer and the electrophotographic printing process.

2.3.05 Fusing Unit

2.3.05 Fusing Unit

The fusing unit consists of a halogen lamp, a fusing roller, a thermistor and a thermostat.

An AC voltage from the power supply board is applied to the halogen lamp under the control of the HEAT ON signal from the main controller board. This AC voltage is applied to the 400 watt halogen lamp. The main controller board controls the fusing roller temperature via the thermistor, and regulates the fusing roller temperature at 150 degrees Celsius by switching the lamp ON/OFF. If the roller temperature rises abnormally, the thermostat in the fusing unit will cut the AC voltage supply OFF.

**2.4 Printing Process General Information

2.4.01 PRINTING PROCESS General Information

Hopping and feeding are controlled by a single registration motor.

Turning the registration motor in the "A" direction drives the hopping roller.

Turning the registration motor in the "B" direction drives the registration roller.

The registration gear and hopping gear contain one-way bearings. Turning each of these gears in the reverse direction will NOT turn the corresponding roller.

The following is too big!!!!

OL400/410ex (96-01-30)

OL400/410ex (96-01-30)

2.4.02 Hopping

2.4.02 Hopping

Hopping loads paper from the paper cassette.

During the hopping operation, the registration motor turns in a clockwise direction.

This motor drives the hopping roller, which in turn advances the paper until the inlet sensor 1 switches ON. The registration gear turns, but the one-way bearing does not allow the registration roller to turn.

After inlet sensor 1 switches ON, the paper is advanced a predetermined length (until the paper reaches the registration roller).

OL400/410ex (96-01-30)

2.4.03 Feeding

2.4.03 Feeding

Feeding transports paper through the printer.

After the completion of hopping, the registration motor turns in a counter-clockwise direction. This counter-clockwise motion drives the registration roller and advances the paper. The hopping gear turns, but the one-way bearing does not allow the hopping roller to turn.

OL400/410ex (96-01-30)

2.4.04 Charging

2.4.04 Charging

Charging applies -1.3 Kvdc to the charge roller. The charge roller contacts the image drum surface.

The charge roller has two layers: a conductive layer and a surface protective layer. The surface layer is flexible, which assures proper contact with the photosensitive drum.

The drum surface charges to approximately -750 vdc.

OL400/410ex (96-01-30)

2.4.05 Exposing

2.4.05 Exposing

The image drum has four layers.

- Carrier Transfer Layer (CTL)

- Carrier Generation Layer (CGL)

- Underlayer (UL)

- Aluminum Base

The CTL and CGL make up the organic photo conductor layer (OPC), which is about 20 micrometers (mm) thick.

When light from the LED head irradiates the image drum surface, the light energy generates positive and negative carriers in the CGL. The positive carriers are moved to the CTL by an electrical field acting on the image drum. The negative carriers flow into the aluminum layer

(ground).

OL400/410ex (96-01-30)

The positive carriers moved to the CTL combine with the negative charges on the image surface

(accumulated by the contact charge of the charge roller), lowering the potential on the image drum surface. The resultant drop in the potential of the irradiated part of the image drum surface forms an electrostatic latent image on it. The surface potential on this irradiated part of the image drum is approximately -100 vdc.

OL400/410ex (96-01-30)

OL400/410ex (96-01-30)

2.4.06 Developing

2.4.06 Developing

The electrostatic latent image formed on the image drum surface is developed into a visible image. Developing takes place when contact is made between the image drum and the developing roller.

As the toner supply roller rotates, toner is absorbed into the sponge type roller material.

A charged particle will be attracted to a particle having a MORE POSITIVE charge than its own.

The developing roller surface is charged to -300 vdc and the toner supply roller is charged to -450 vdc. Since the development roller is charged more positive than the toner supply roller, the toner on the toner supply roller is attracted to the developing roller. The toner on the developing roller contacts the doctor blade, forming a thin coat of toner on the developing roller surface.

The exposed portion of the image drum contains a more positive charge than the development roller (-100 vdc vs. -300 vdc). Therefore, toner is attracted to the exposed areas of the image

OL400/410ex (96-01-30)

drum, making the electrostatic latent image visible.

NOTE: The toner supply roller and the developing roller are supplied with the bias voltages required during the developing process. The toner supply roller is charged to -450 vdc.

The developing roller is charged to -300vdc.

OL400/410ex (96-01-30)

2.4.07 Transfer

2.4.07 Transfer

The transfer roller is made of a conductive sponge material. The roller keeps the paper in constant contact with the image drum. Paper is placed over the image drum surface. A positive charge (opposite in polarity to the toner) is applied to the paper from the reverse side.

A charged particle will be attracted to a particle having a MORE POSITIVE charge than its own.

A high positive charge is applied to the transfer roller by the power supply board. This induced charge (on the surface of the transfer roller) is transferred to the paper when contact is made between the transfer roller and the paper. The lower side of the paper is positively charged. The negatively charged toner (on the image drum) is transferred to the upper side of the paper because of the positive charge on the lower side of the paper.

OL400/410ex (96-01-30)

2.4.08 Fusing

2.4.08 Fusing

After transfer, the toner image is fused to the paper by heat and pressure. The paper passes between the fusing roller and the pressure roller. The fusing roller has a teflon coating and contains a 400 watt halogen lamp. A thermistor (which contacts the fusing roller) maintains the fusing roller temperature at approximately 150 degrees Celsius. A thermostat cuts off the voltage supply to the lamp if there is an abnormal temperature rise.

The pressure roller provides 2.5 Kg of pressure. This is generated by the pressure springs at each side of the roller.

OL400/410ex (96-01-30)

2.4.09 Cleaning

2.4.09 Cleaning

The image drum is cleaned at the end of transfer. The residual toner on the image drum is attracted to the cleaning roller, which has a + 500 vdc static charge. This residual toner is accumulated in the image drum cartridge until the drum is replaced.

OL400/410ex (96-01-30)

2.4.10 Printing

2.4.10 Printing

Refer to the Printing Process Diagram.

Printing is accomplished as follows.

Approximately - 1.3 Kvdc is supplied to the charge roller. This causes the drum to charge to approximately - 750 vdc.

The LED head is turned ON by the printer control board in accordance with signals from the main control board. This causes a latent electrostatic image to be formed on the surface of the drum.

Through the development process, a toner image replaces the electrostatic image.

A + 1 Kvdc charge is applied to the transfer roller. This causes the toner image to be transferred to the receive paper.

Heat and pressure cause the toner image to become fused to the receive paper. The 150 degree Centigrade fusing temperature is attained by turning a 400 watt halogen lamp ON.

The fusing temperature is controlled by a thermistor. In the event of a thermistor failure, a temperature fuse will OPEN, turning off the quartz lamp, and preventing equipment damage.

The residual toner is removed from the drum.

2.5.01 Paper Jam Detection

2.5.01 Paper Jam Detection

Paper jam detection monitors the location of paper when the printer is powered ON and during printing. If any of the following jams are present, the printing process is interrupted and the message PAPER JAM will be displayed on the LCD.

To return to the printing process, the paper jam condition MUST be cleared. This is accomplished by opening the upper cover, clearing the jam, and closing the cover.

Paper Outlet Jam

This jam occurs if the paper does NOT pass over the outlet sensor within a pre-determined period of time. However, the paper has already passed over the paper sensor.

Paper Size Error

The time interval between when the paper contacts the paper sensor and the outlet sensor determines which size (length) paper is being used.

This error occurs if the paper size of the loaded paper differs by + 45 mm or more from the paper size set by the menu.

Cover Open Switch

When the stacker cover is opened, the cover open microswitch on the power supply unit is deactivated. This disables the + 38 vdc and the high voltage power supply circuit. As a result, all high voltage outputs are interrupted. At the same time, the CVOPN signal is sent to the main control board to notify it of the OFF state of the microswitch. The main control board executes the cover open routine. The operation panel displays the message COVER OPEN.

OL400/410ex (96-01-30)

Paper Inlet Jam

Paper Inlet Jam

This jam occurs when either of the following situations occur.

When the printer is powered ON, paper is at inlet sensor 1.

After the hopping operation is attempted three times, the leading edge of the paper does NOT reach inlet sensor 1.

2.5.02 Toner Low Sensor

2.5.02 Toner Low Sensor

The toner well of the image drum cartridge contains a toner agitator. Whenever the image drum rotates, the toner agitator attempts to turn. A spring clip in the bottom of the toner well

(along with the proper amount of toner) holds the agitator at the bottom of the well. However, when toner is distributed unevenly or an insufficient amount of toner is in the well, the toner agitator will rotate. Therefore, as long as the toner well contains an adequate supply of evenly distributed toner, the toner agitator will not rotate.

The toner sensor plate has a magnet embedded in it. Whenever the toner agitator is positioned at the bottom of the toner well, the toner sensor plate is magnetically attracted to the toner agitator. This causes the toner sensor plate to be lifted from the path of the toner sensor.

During a low toner condition, the toner agitator will rotate continuously. This causes the toner sensor to turn ON / OFF as the image drum rotates. The operator panel will then display the

TONER LOW message.

During an unevenly distributed toner condition, the toner agitator will rotate until the toner is distributed sufficiently. This causes the toner sensor to turn ON / OFF for only a few image drum rotations. The operator panel will not display an error message since this is normal printer operation.

If the toner sensor remains activated (ON), the operator panel will display the TONER SNS message.

Customers may experience a "TONER SNS" or "TONER LOW" message with a brand new printer.

This may occur even though a new toner cartridge and drum have been installed.

This can occur for the first 30 pages. Between 30 and 200 pages, the CPU will turn OFF the toner sensor. This will eliminate the message on the LCD. After 200 pages, the printer will begin checking for proper operation of the toner sensor flag.

Customers should use the printers for at least 30 pages. The "TONER SNS" or "TONER LOW" messages do not cause any print quality problems. The unit is in NO danger of suffering any damage. If the problem persists for more than thirty pages, customers are directed to contact a service center for warranty repair. This information is documented in TSB 5604( ).

OL400/410ex (96-01-30)

2.5.03 Paper Path

2.5.03 Paper Path


The automatic and manual feed paths are different. In addition, the path will change if the paper is ejected face up or face down. Paper fed from the paper tray (automatic feed) and ejected face down will follow an "S" path. The path with the least amount of turns is a manual feed, face up ejection.

Automatic Feed

Load paper into the tray. The side to be printed on should be facing DOWN.

The leading edge of the paper should face the FRONT of the printer. Refer to either the face down or the face up section for further paper path details.

Manual Feed

Manually load the paper into the unit. The side to be printed on should be facing UP.

The leading edge of the paper should face the BACK of the printer. Refer to either the face down or the face up section for further paper path details.

Face Down

The hopping roller picks up the paper. The hopping roller transports the paper to the registration roller. The registration roller transports the paper to the image drum. Then, the paper passes between the fusing roller (on top) and the pressure roller (on the bottom). The paper is then routed upward and is ejected from inside the unit.

Face Up

The hopping roller picks up the paper. The hopping roller transports the paper to the registration roller. The registration roller transports the paper to the image drum. Then, the paper passes between the fusing roller (on top) and the pressure roller (on the bottom). The paper is then ejected from the inside of the unit.

*4.4.03 Common Problems

4.4.03 Common Problems

A "TONER SNS" or "TONER LOW" message appears on a new printer.

Customers may experience a "TONER SNS" or "TONER LOW" message with a brand new printer. This may occur even though a new toner cartridge and drum have been installed.

This can occur for the first 30 pages. Between 30 and 200 pages, the CPU will turn OFF the toner sensor. This will eliminate the message on the LCD. After 200 pages, the printer will begin checking for proper operation of the toner sensor flag.

Customers should use the printers for at least 30 pages. The "TONER SNS" or "TONER LOW" messages do not cause any print quality problems. The unit is in NO danger of suffering any damage. If the problem persists for more than thirty pages, customers are directed to contact a service center for warranty repair.

This information is provided in Technical Service Bulletin 5604 ().

The unit appears to be without power.

If the operator panel or the operator panel cable are not properly attached, the unit will appear to be completely without power.

Symptoms include: no operator panel display, no power to the fan, no movement of the motors or gears, and no lighting of the fuser lamp.

The symptoms usually occur after the upper cover of the printer has been removed and then replaced (repairs, firmware upgrades, etc.).

The symptoms may also occur if the operator panel is dislodged by the end user.

The operator panel cable can be easily damaged during the removal and installation of the upper cover. Dislodging, cutting, and/or crimping of the cable can occur if the technician does not follow the disassembly procedure for the upper cover (Section 3 of this Service Handbook).

When diagnosing initialization failures, refer to RAP 1 ( ) of this Service Handbook.

This information is provided in Technical Service Bulletin 5605.

The unit makes a tapping noise when the fan is running.

The noise is only apparent in quiet environments and does not exist on all OL4xxe printers.

To correct the problem, remove the small piece of foam located inside the upper cover of the printer. The foam is glued to the cover, just behind the fan. Be careful not to damage the upper cover when removing the foam.

Follow the disassembly procedure (Section 3 of this Service Handbook) for removing the upper cover.

Power ON the unit to verify that the problem has been corrected.

If the noise is still heard, loosen the upper cover screws and slightly shift the cover towards the back (rear) of the printer.

Tighten the screws.

OL400/410ex (96-01-30)

The noise should stop.

This information is provided in Technical Service Bulletin 5606.

The printer feeds between 100 - 150 pages. Then, pages won't feed.

Check the feed rollers. Is a slick film present on the rollers?

If yes, check the type of paper being fed. Paper with a high cotton content will coat the rollers with cotton fibers. The fibers make the rollers "slick" and paper will not feed.

Clean the rollers with water.

Cotton free or low cotton content (25% or less) should be used.

ERROR 05 9FC2160C appears on the operator panel when printing either the menu or print fonts.

This occurs when either the menu or print fonts is run after a demo page is printed.

This problem is related to the firmware.

Firmware revision 2.14 (or later) will correct the problem.

The paper tray will NOT stay in the unit.

Check the two tabs in the base assembly.

These tabs hold the paper tray in place.

If they are broken, replace the left and right cassette guides.

*4.4.04

Audible Roller Noises

4.4.04 Audible Roller Noises

NOTE: The information in this section is also covered in TSB 5608 / FCO 8126.

Symptoms

The unit "squeaks and squeals" whenever the rollers in the unit are turning.

Cause

The copper frame ground clip of the fuser pressure roller requires lubrication.

When viewing the printer from the front, the clip is on the right hand side.

Solution

Lubricate the clip.

To access the clip, disassemble the unit to the fusing unit assembly.

Refer to Section Three of this Service Handbook for disassembly information.

Apply a very small amount of Dow Corning Molykote HP 300 grease to the face of the ground clip, where the clip contact the fuser pressure roller.

DO NOT OVER LUBRICATE. Excess lubricant will attract toner and could cause problems.

Assemble the unit.

Okidata FCO Kit 8126 (P/N 58235401) includes the grease and instructional diagrams. Each kit

contains enough grease for many applications.

OL400/410ex (96-01-30)

*4.4.05 Audible Noise / Input Jams From Paper Cassette

4.4.05 Audible Noise / Input Jams from Paper Cassette


Symptoms

The unit "squeaks and groans" when paper is fed into the printer.

Paper jams when being fed from the paper cassette.

Cause

The paper separator frame inside the paper cassette.

"Squeaks" are caused by the paper separator frame rubbing against the paper cassette.

"Groans" are caused by the separation rubber of the paper separator frame. The separation rubber is either deformed or does not fit properly.

Solution

Okidata FCO Kit 8127 (P/N 58235501).

This kit includes grease, a spring, a separation rubber, TSB 5609, and an installation instruction sheet.

The grease lubricates the assembly.

The spring provides more side to side pressure.

The separation rubber is trimmed to a more appropriate size. It is also more securely attached to the new paper separator frame.

Remove the paper cassette and follow the instructions in the FCO Kit 8127.

Paper Feed Jams

Paper jams occur at or near the registration roller.

The leading edge of the paper (in most cases) stops under the drum unit.

Print Registration Errors

The printed page does not begin at the top of form.

In some cases, the print shifts down from the top of the page.

Print Skewing

Printed pages may be visible skewed.

To verify, follow this procedure.

Load paper in the cassette.

Take the printer OFF-LINE.

Press PRINT FONTS.

The Print Fonts Test will print.

This test will dramatically show the skew, if it is present.

Cause

This problem is caused by a misalignment of the pinch roller clips on version B8 image drums.

The pinch rollers on the bottom of the drum unit provide the pressure needed to move the paper evenly through the registration rollers. Misalignment is caused when the retaining clip slightly rotates towards the pinch roller. The pinch roller is normally level, but a rotated clip will tilt the roller.

Because of the tilt of the pinch roller, uneven pressure will be applied to the registration roller.

(Note the space between the edge of the retaining clip and the drum's outer ribbing. Refer to the diagram.) Rough handling during shipping may cause the retaining clips to rotate.

To identify a version B8 image drum, look at the white label on the left leading edge of the drum.

The first two characters of the drum lot number are the version.

OL400/410ex (96-01-30)

Solution

To correct this problem, follow this procedure.

- Remove the image drum unit from the printer.

- Turn the drum so the pinch rollers face up.

Be careful NOT to spill toner.

Do NOT touch the surface of the drum.

Touching the drum may cause permanent damage to the drum's surface.

- Use a pair of needle-nose pliers to press the retaining clip against the plastic ribbing

closest to the clip. If done correctly, there will little or no space between the retainer clip

and the plastic rib.

- Repeat the process until all four clips have been levelled.

- Place the drum back into the printer.

- Test the printer be running the Print Fonts Test.

- Load paper in the cassette.

- Take the printer OFF-LINE.

- Press PRINT FONTS.

- The Print Fonts Test will print.

This test will dramatically show the skew, if it is present.

OL400/410ex (96-01-30)

- If the problem still occurs, the image drum unit may need to be replaced or the printer may

be experiencing a different failure.

OL400/410ex (96-01-30)

*4.4.07 Paper Jams Under The Fuser Roller

4.4.07 Paper Jams Under the Fuser Roller


Symptoms

The paper jams under the fuser roller and must be removed by a technician.

The leading edge of the paper is stuck in the area of the paper exit lever.

The rest of the page "bunches up" under the fuser roller.

The end user cannot remove the paper. Not enough paper is visible/available for the end user to grasp and remove.

Solution

Install the recommended exit sensor lever assembly and/or firmware (listed below).

Lever: Exit Sensor (Assembly) P/N 51010802

Firmware (OL400e) P/N 31097905

Self-Test Revision Number 3.03 or higher.

Firmware (OL410e) P/N 31098302

Self-Test Revision Number 2.0 or higher.

Some printers may require only sensor levers. Some may require only firmware.

Check the Self-Test Revision Number BEFORE changing the firmware. The printer may already include the recommended firmware.

Printers with serial numbers HIGHER than those listed below will require the installation of the recommended firmware. The recommended sensor is already installed.

OL400e 120 volt

OL400e 2XX volt

OL410e 120 volt

OL410e 2XX volt

310A0086272

310A0000245

308A0005201

312A0000129

ALL printers with a serial number 404xxxxxxx include both the recommended sensor and the recommended firmware.

The recommended exit sensor lever assembly does not "catch" the leading edge of the paper.

This part is installed in place of the Plate: Sensor Outlet. To reach the part, the lower

base must be removed. Refer to Section 3 for disassembly procedures.

OL400/410ex (96-01-30)

The recommended firmware changes the timing of the paper jam signal to prevent the paper jam and allows more paper to be available to the user to grasp and remove. Users will be able to clear the jam without calling for service.

The firmware is located on the main controller board.
