Recommended Media
Transparency: · To avoid damaging the printer, do not use ink jet transparency. · Transparencies and adhesive material of labels should be stable at 205°C ( 400°F ), the printer's maximum temperature. · Re-using transparencies that have been fed through the printer once ( for example, after jams or if the transparency is ejected without being printed ) can reduce the life of the consumables and paper path components. · When using transparencies, if the print quality is poor, print on the other side. Labels: · With any label stock, the labels must completely cover the backing material. Envelope: It is recommended that you purchase only high quality envelopes with diagonal seams, as shown in the diagram below:
High quality envelopes have the following characteristics: · A thin, sharply creased leading edge · Paper weight of 90 g/m2 ( 24 lbs. ) · Flat, free of curls, wrinkles, nicks, etc. Note: Wrinkles may occur, even when using high quality envelopes.

Print Process
1.7.1.
Charge
The charge corona applies a high, uniform positive charge to the surface of the organic photoconductor ( OPC ) drum. The charge level is approximately 900 VDC and remains because the OPC drum has a high electrical resistance when concealed in darkness.
1.7.2.
Exposure
The laser beam passes through the collimator lens, is reflected by the polygon mirror, and is focused onto the drum after passing through an image-forming ( ) lens and a reflectionmirror. Wherever the laser beam strikes the drum, the positive charge dissipates. A latent electrical image of two different voltages potentials, which corresponds to the original page, is formed on the OPC drum.
1.7.3.
Development / Cleaning
Development: Non-magnetic toner is supplied to the conductive roller by the toner supply roller. The toner on the conductive roller is positively charged by friction with the toner supply roller, and the doctor blade ensures a thin layer on the surface of theconductive roller. Wherever the conductive roller touches the drum, the positively charged toner is attracted to the latent image on the drum, and the latent image is converted to a visible toner image. A bias voltage of approx. 350 VDC is appliedto the conductive roller to achieve maximum print quality. 15
KX-P7100
Cleaning: After transfer, residual toner remains on the drum surface, and for next printing, the residual toner reaches to the development area via charge and exposure. The charge level of the OPC corresponds to the white background is +900VDC, andthe bias voltage of the conductive roller is approx. +350VDC. Therefor the positively charged residual toner on the OPC drum is attracted and collected to the conductive roller. The charge level of OPC after exposure is +100VDC. So,the printing area of the OPC is cleaned.
1.7.4.
Transfer
As the paper is fed between the drum and the transfer roller, a high negative charge is applied to the back of the paper. The positive toner particles are then attracted from the drum surface to the paper. After transfer, the paper is separatedfrom the drum surface by the curvature of the drum.
1.7.5.
Fusing
The paper passes through the fuser rollers and is subjected to heat and pressure. The fusing temperature is approximately 190°C ( 382.5°F ), and the pressure is approximately 0.36kg/cm ( 3.53N/cm ). This bonds,or fuses, the toner into the paper.
16
KX-P7100
1.8.
Paper Feed
Media Tray The main motor drives the pickup roller after the pickup solenoid is energized, which engages the pickup roller clutch and feeds a sheet of paper. The paper is pushed to the paper feed roller, which overdrives the paper slightly causing a buckleto ensure the paper is aligned with the stationary registration roller. While triggering the registration sensor notifying the CPU paper is ready to feed. The paper at this point is the same as manual feed. Manual Feed when paper is inserted, it activates the registration sensor. At the porter time, the CPU energizes the registration solenoid that allows the registration roller to rotate, feeding paper to the top sensor.

Laser Scan Unit ( Exposure )
Operation Theory
The light beam from the laser diode ( light source ) is modulated by the digital signal (nVIDEO) and converted to parallel light waves by the collimator lens. The beam is then sent to the rotating polygon mirror (polygon scanner), where it is reflectedthrough the lens and then focused onto the OPC drum surface. The diameter of the beam is about 80 µm, and the light moves across the surface of the OPC drum in the scanning directionof right to left. As the drum rotates ( sub-scans ), a static image is formed where the laser beam touches the drum surface. The laser beam is also deflected to the timing sensor. This sensor controls the start timing of scanning on the drum, providing a consistent left margin. The CPU uses the timing sensor to detect abnormal signals.
1.9.2.
Laser Beam
The laser beam is pulsed on and off by the digital signal (nVIDEO) to form a latent image of two different voltage potentials on the drum, as shown below.

1.9.3.
Collimator Lens
The collimator lens converts light from the laser diode to parallel light. This aids in scanning and provides better convergence to a dot.
1.9.4.
Polygon Scanner
The polygon scanner consists of a 6-sided mirror directly driven by a brushless DC motor at a rate 20,078.74 rpm. The laser beam is reflected across the OPC drum by the mirror faces and produces the scan. One mirror face is equal to one main scan.This unit features stable line scanning speed, precision mirror surface reflection angle, reflect-free surfaces, and instant start.
Polygon Scanner Specifications Item Mirror Revolution Specification 6 20,078.74 faces rpm
1.9.5.
Cylindrical Lens and
Lens
Each of the polygon mirror surfaces has a slight imperfection. This prevents the beam from scanning the OPC drum surface at the constant interval in the sub-scan direction. The cylindrical lens and lens are used for correcting this uneven laser scanning.
1.9.6.
Lens
This lens ensures that the beam scans across the surface of the OPC drum at a constant rate. The beam is refracted to parallel light as it passes through the lens to ensure that the dots at the edge of the drum and at the center of the drum areequally spaced. This lens also provides a set focal length for laser beam.
Specifications Item Scanning Width Focusing Light Spot Size Specification 207.43 80 x 90 mm µm
1.9.7.
Timing Sensor
This sensor detects the laser beam and determines the start timing for scanning. A pin photodiode is used as the timing sensor.

KX-P7100
1.10. Fuser Unit
A 600W heat lamp ( halogen lamp ) heats the surface of the teflon-coated heat roller to approximately 190°C ( 374°F ), a thermistor monitors the heat roller temperature, and the CPU controls the ON/OFF timing of the lamp. The thermostat is mounted 2.5mm away from the heat roller. If the ambient temperature reaches 180°C ( 356°F ), the thermostat is opened, and power is removed from the heat lamp. The surface of the thermostat is not as hot as thatof the heat roller. When the thermostat opens, the surface of the heat roller may reach 200°C ( 382°F ), and the system displays E30. If the thermistor opens, the system displays E32. If by chance the thermostat malfunctions a thermalfuse opens. The pressure roller is kept in contact with the heat roller through 2 pressure springs, which apply a pressure of approximately 0.36 kg/cm ( 3.56 N/cm ). Drive is supplied from the main motor via intermediate gears.
20
KX-P7100
1.11. Paper Ejection and Paper Switchback
A. Normal Printing Mode ( Not Duplex Mode ) After fusing, paper is fed to the output tray by the switchback roller and switchback pinch roller. The paper exit/ADU paper jam sensor detects paper. If paper does not arrive at the sensor within a predetermined period of time, "Jamat A" is displayed, and if paper remains at the sensor beyond a predetermined period, "Jam at B" is displayed on the computer screen. Paper is ejected face down and stored in the output tray.
B. Duplex Mode After fusing, paper is fed to the output tray by the switchback roller and switchback pinch roller. The paper exit/ADU paper jam sensor detects paper. If paper does not arrive at the sensor within a predetermined period of time, "Jamat A" is displayed on the computer screen. At the specified time after the sensor detects the bottom of paper, the switchback roller rotates in reverse direction, turning on the switchback solenoid to move the ratchet lever to Duplex Position.As a result, the paper is fed to the development area through the Auto Duplex Unit ( ADU ) ( see section 1.4 Component Layout and Paper Path ). If paper remains at the sensor beyond a predetermined period, "Jam at E" is displayed.Paper is ejected face down and stored in the output tray.

4.4.16. Fan Control Circuit
FANCTL: 1. Full Power Mode When FANCTL signal ( pin 6, IC11 ) is high, pin 7 of IC9 goes high, transistors Q15 and Q17 are turned on. This supplies +24V Power to Fan motor and rotates the Fan. 2. Reducing Power Mode ( Quiet Mode ) Pulse signal ( see below ) is output from pin 6 of IC11.
This pulse signal is integrated by R177, C181 and C175. Voltage of ( A ) is stabilized at approx. 2V. Pin 6 of IC9 is 0V. When the voltage of ( B ) is lower than the voltage of ( A ), pin 7 of IC9 goes high, Q15 and Q17 are turned on, then the voltage of ( B ) increases. When the voltage of ( B ) is higher than ( A ), pin 7 of IC9 goes low, Q15 and Q17 are turned off,then voltage of ( B ) decreases. Thus the voltage of ( B ) is controlled almost same as the voltage of ( A ) ( = approx. 2V ). Since the resistor network of R180 and R181 divide the voltage of ( C ) into 1/8, the voltage of ( C )is controlled approx. 16V ( = 2V x 8 ).
