Page An optics anti-condensation heater is available as an option.

It can be installed on the left side of the scanner. It turns on whenever the power cord is plugged in. Lamp Stabilizer Fuse BD Magnification in the sub-scan direction can be adjusted by changing the ADF motor speed using SP In the main scan direction, it can be adjusted with SP, like for book mode. If the copy is made with the platen fully open, the CPU decides the original size from the sensor outputs when the Start key is pressed. Page because of the longer time required for scanning , but it will be normal for the rest of the job.

America does not have the IMB as standard equipment. Each pixel will be assigned a value on a scale of 64 grades. Then, the digitized image data goes to the BiCU board. Page Ipu Image Processing Unit 7. Binary picture processing 8. Error diffusion 9. Dithering Video path control Test pattern generation The image data then goes to the VCU. Page Use instead of Normal Text if, e. Use if the customer wishes to keep this background. Page Auto shading is done before scanning for the first original as well as after scanning each page to prepare for the next page.

If the image density or the original mode is changed during a copy run, auto shading is done before scanning the next original. Page In ADF mode, if extremely low CCD output is detected on the scanning line before the leading edge of original arrives there, this is attributed to abnormal black dots on the exposure glass.

This low output is corrected using neighboring pixels. To adjust or switch off this correction, use SP Page The disadvantage is that it in some cases images come out lighter than the customer desires.

Therefore as mentioned above, the main scan start position will be at the opposite corner. Special 2 uses the same type as Text 1, and Special 1 uses the same type as Text 2. In all modes, ID gamma correction can be adjusted with SP Page more texture removal.

Dithering Each pixel is compared with the threshold in a dither matrix. Several matrices are available to bring out half-tone areas in images such as newspaper-type photographs. Dithering is only used for Special 3 and Special 4.

B, B 16MB standard. Page Video Control Unit Vcu Printer correction corrects the data output from the IPU to the laser diode to account for the characteristics of the engine components e. The machine chooses the most suitable gamma curve for the original type selected by the user. There is no SP adjustment for this. Page Auto Power Control Apc This auto power control is done just after the machine is turned on and during printing.

The laser diode power is adjusted on the production line. Page Ld Safety Switch When the front cover or the right cover is opened, the power supply to the laser diode is interrupted. Page Photoconductor Unit Pcu 7.

Development Unit 3. Pick-off Pawl 8. Charge Roller 4. Charge Roller Cleaning Brush 5. ID Sensor see note Page Drive The main motor [A] drives the drum [B] through a series of gears and the drum drive shaft [C]. The main motor assembly includes a drive controller, which outputs a motor lock signal when the rotation speed is out of the specified range.

Page Drum Charge [A] always contacts the surface of the drum [B] to give it a negative charge of — The high voltage supply board gives a negative charge of — V to the drum charge roller through the screw [C] and terminal plate [D]. This voltage can be changed using SP This voltage is compared with Vsg read from the bare drum at the same time. The minute interval can be changed using SP WMF Because the drum charge roller [A] always contacts the drum, it gets dirty easily.

So, the cleaning brush [B] also contacts the drum charge roller all the time to clean the surface of the drum charge roller. Page This machine uses a single-roller development system. Two mixing augers mix the developer. The toner density TD sensor and image density ID sensor see the illustration in the PCU section are used to control the image density on the copy.

Page Developer Mixing [H], towards the front of the machine. Mixing auger 1 [F] returns the excess developer, along with new toner, to the rear of the mixing assembly. Here the developer is reapplied to the development roller. Page Development Bias — volts to the development rollers throughout the image development process. The bias is applied to the development roller shaft [A] through the drive shaft [B]. The development bias voltage — V can be adjusted with SP Page Toner Supply When the bottle holder unit is pulled out to add a new toner bottle, the toner shutter shuts to block the opening as a result of pressure from a spring.

Page Toner Supply Mechanism [D]. Then the toner falls down into the development unit through the slit and the shutter. If Vt becomes greater than the reference voltage, the machine supplies additional toner.

This can be checked using SP If the machine detects the TD sensor error condition 10 times consecutively, an SC code is generated SC and the machine must be repaired. The recovery procedure is the same as for toner near end. It takes about two minutes. Then, this toner falls into the development unit with new toner coming from the toner bottle and it is all mixed together by mixing auger 1 [C] and used again.

Page Paper Feed The components of the paper feed station are as follows. Paper End Sensor 5. Upper Relay Roller 2. Paper Feed Roller 6. Upper Relay Sensor 3. Registration Roller 7. Lower Relay Sensor 4. Paper Size Switch 8. The friction pad applies pressure to the feed roller with a spring [C]. The friction pad pressure cannot be adjusted. Page Paper Lift Mechanism [B] in the tray bottom plate and the paper end sensor is activated. When the paper tray is drawn out with no paper in the tray, the shape of the paper end feeler causes it to lift up.

If the paper size for this position is changed without changing the User Tool setting, a paper jam will result. Page Side Fences When feeding from the by-pass tray, the by-pass feed clutch is activated, turning the by-pass feed roller. This feature may be needed when feeding thick paper, and cannot be used for the first paper feed tray.

Page Image Transfer And Paper Separation The curvature of the drum and the discharge plate [C] help the paper to separate from the drum.

The discharge plate is grounded. Drive from the drum through a gear [D] turns the transfer roller. This may cause a ghosting effect, in which part of the image at the top of the page is repeated lower down the page at a lower density.

In the worst case, it may also damage the OPC drum. WMF The discharge plate [A] and the drum curvature of the drum help the paper to separate away from the drum. Page Image Fusing And Paper Exit The fusing unit release mechanism automatically disengages the fusing unit drive gear [D] when the right cover [E] is opened.

This allows the fusing unit drive gear to rotate freely so that misfed paper can easily be removed. Applied pressure can be changed by adjusting the position of the pressure springs. The spring is positioned at the end [D] as the default setting. However, generated noise increases if the setting is changed from the default.

If a radio or a TV is close by the machine, the noise may have some effect on the image or sound. Page Overheat Protection There is also a thermofuse to ensure overheat protection. The thermofuse is farther from the hot roller than the thermostat, so it opens later than the thermostat.

Reverse Table Roller 3. Pick-up Roller 8. DF Feed Clutch 9. Exit Roller 5. DF Transport Motor WMF The original size detection mechanism consists of the original width sensor board [A] and two original length sensors-1 [B] and -2 [C].

Based on the combined output of the length sensors and the width sensor board, the machine can detect the size of the original. WMF The original is set with the image facing up.

The original pushes actuator [A] and the original set sensor [E] is activated. After pressing the start button, the pick-up solenoid [D] is activated and the lift plate [C] lifts the original up until it comes in contact with the pick-up roller [B].

When the registration sensor [B] detects the leading edge, the motor stops for a short while. WMF AD WMF When the registration sensor [B] detects the leading edge of the original, the DF feed motor which drives the feed roller and transport motor which drives the transport roller both switch off. After a brief interval, the transport motor alone reactivates to drive the first transport roller [A] and second transport roller [G] and the exit roller [F]. WMF The original is then sent to the reverse table [H] a second time to be turned over.

This is done so that the duplex copies will be properly stacked front side down in the exit tray [J] in the correct order. WMF This function is only for fax mode. There is a stamp [A] between the 2nd transport roller [B] and the exit roller [C], and its solenoid is controlled by the copier directly.

When the original reaches the stamp position, the DF feed motor stops. At milliseconds after stopping the DF feed motor, the stamp solenoid turns on if the page was sent successfully immediate transmission or stored successfully memory transmission.

WMF B WMF B The DF CPU also monitors all DF sensors and provides updated status information when prompted at regular intervals by the mainframe, which may then take action based on this information. Open the left cover.

Pick-up roller B WMF The DF uses two width sensors width sensor 1 [A] and width sensor 2 [B] to detect the original width, and two length sensors length sensor 1 [C] and length sensor 2 [D] to detect the original length. Setting original s onto the feed table lifts the original set sensor feeler [A], causing the original set sensor [B] to issue a signal informing the main CPU that the DF is ready to start feeding.

After a short time the DF transport motor turns on again. The original is fed past the DF exposure glass [B], where it is scanned. The fax unit includes the stamp. The stamp solenoid [A] is located between the 2nd transport roller [B] and the exit roller [C].

The copier controls this solenoid directly. When the original reaches the stamp position, the DF transport motor stops. The DF CPU also monitors all sensors and provides updated status when prompted at regular intervals by the mainframe, which may then take action based on this information. Lift the DF.
