Transfer Unit
The transfer assembly consists of the PTL (pretransfer lamp) and the transfer roller. The PTL sends light to the OPC drum. This lowers the charge on the drum's surface and improves transfer efficiency. The transfer roller moves toner from the OPC drum surface to the paper.

Slide 52

5. Engine

More on the Transfer Unit The charging voltage, developing voltage and the transfer voltage are controlled by PWM (Pulse Width Modulation). Each output voltage is changeable according to the PWM duty cycle. The transfer voltage used when the paper passes the transfer roller is decided by environment recognition. The resistance value of the transfer roller changes due to the surrounding environment in the room or within the machine. This change in resistance in turn changes the value of the voltage due to loading. This voltage is fed back into the set through the A/D converter. Based on this fed back value the PWM cycle is changed to maintain the required transfer voltage.

Slide 54

5. Engine

More on the Fusing Unit The temperature of the heat roller's surface is measured with a thermistor. The AC power is controlled by comparing the target temperature to the value from the thermistor. An error shows if the value from the thermistor is out of the controlling range during the fusing process.

Fusing Unit Components
Thermostat The thermostat cuts off the power to the fusing lamp to not let the machine overheat. Power gets cut when the thermostat temperature gets to 160°C Thermistor The thermistor detects the surface temperature of the hot roller. This information goes to the main processor, to regulate the temperature of the hot roller Hot Roller The fusing lamp heats the surface of the hot roller. Toner gets melted and stays on the surface of the paper when the paper passes between the hot roller and pressure roller Pressure Roller The pressure roller is mounted under the hot roller

Slide 58

5. Engine

More on the Laser Scanning Unit The laser-scanning unit converts the video data received from the computer into an electrostatic latent image on the surface of the OPC drum. This is achieved by controlling the laser beam and exposing the surface of the OPC drum to the laser light. The polygon mirror reflects the laser light onto the OPC. Each side of the mirror is one scan line. The OPC drum turns as the paper feeds to scan the image down the page.

More on Toner Cartridge The toner cartridge contains the OPC unit and toner unit. The OPC unit consists of the OPC drum and charging roller. The toner cartridge unit consists of the toner, supply roller, developing roller, and doctor blade. There is no toner near end sensor in the machine. But the machine has a toner remaining amount sensor. A cleaning blade is used to collect used toner. Developing method: Non magnetic 1 element contacting method Toner: Non magnetic 1 element shatter type toner Toner life span: 5,000 sheets (IDC Pattern/A4 standard) OPC cleaning: Electrostatic process

New AIO Detection
A new supply AIO cartridge has a ID chip. The machine knows a new cartridge has been installed when the chip gets detected.

Slide 60

5. Engine

More on New Toner Cartridge Detection When the new cartridge is installed in the machine, the machine automatically detects by the ID chip that the cartridge is brand-new. Then the machine resets the total dot counter (TOTAL TONER COUNT) and CRU print counter (Cru Prints). and increments the counter for counting the number of CRU replaced (Replaced Toner Counts). In the case when the "Replaced Toner Counts" is 0, the CRU currently installed is regarded as a starter CRU. In this condition, threshold to detect toner end is shorter than that for supply CRU.

Ricoh Europe B.V. Technical Training Centre

www.get-u-wice.com

B273

Toner End Detection
The machine does not have a toner end sensor. The machine checks the amount of toner with software. The machine counts and adds up black dots as toner consumption. For example, the following occurs when the machine prints 5% of test chart.
» Starter cartridge: Approx. 4,750,000,000 dots will be added » Supply cartridge: Approx. 7,500,000,000 dots will be added

You can check the total dot counts from the current cartridge in the System Data List in TECH mode.
Slide 61

5. Engine

More on Toner End Detection When the total number of dots gets to a pre-programmed figure (as for toner near-end), the machine shows "TONER LOW". After another period of dots has been counted up, the machine finally shows "TONER EMPTY" (as for toner end), and the machine stops printing.

Service Manual, Section 6.4.1. to 6.4.2 More in SMPS and HVPS The SMPS supplies either 110V or 220V DC power to the system, and outputs +5V, +12V and +24V supplies to the main and other PBAs. The HVPS creates the high voltage of THV/MHV/Supply/Dev and supplies it to the toner cartridge. The CPU modifies some of these voltage settings to provide the ideal voltages to create the image. The HVPS part uses the 24V, and outputs the high voltage for THV/MHV/BIAS. Outputted high voltage is supplied to the following parts: Toner Cartridge OPC Cartridge Transfer roller.

Fusing Unit
The procedure to reassemble the fusing unit is a bit complicated. The stripper pawls must be put in the correct position before you can reassemble the fusing unit. Stripper pawls (red circles) and stripper pawl heads (red arrows) must be set as shown below.

Slide 83

7. Replacements and Adjustments

More on Reassembling the Fusing Unit The most important thing to note when you reassemble the fusing unit, is the position of the 4 stripper pawls. The stripper pawls must be put back to their original position when you reassemble the fusing unit. The machine will still work if the stripper pawls are not put back in their correct positions. However the print quality will be severely affected. There is a procedure to do this. 1. Remove the stripper pawls from the stripper pawl slots. 2. Put the top part of the fusing unit and the bottom part of the fusing unit together again. 3. Set the stripper pawls into the stripper pawls holder slots and snap them into the slots. 4. Make sure the stripper pawl heads sit as they are shown in the slide. 5. Finally, reassemble the rest of the fusing unit.
