65 Component layout 65 ARDF relay board Junction gate solenoid Upper cover sensor Original set sensor Pick-up solenoid ARDF motor Transport sensor

66 Drive The ARDF motor drives all the rollers. The pick-up roller and Junction gate are operated by a solenoid. 66 ARDF motor Pick-up solenoidJunction gate solenoid

67 Original detection The stopper prevents the user from placing originals too far into the feeder. 67 StopperOriginal set sensor

68 Pick-up The pick-up solenoid drops the pick-up roller onto the top original of the stack. This moves the stopper out of the way, and the original can be fed to the feed roller. The friction pad ensures that only one sheet of the original enters the feeder at a time. 68 Feed Roller StopperPick-up Roller Friction Pad

69 Feed For single-sided scanning, the original passes through the ARDF as shown below to the exit tray. 69 Scanning guide plateTransport sensor Scanning roller Pull-out roller

70 Duplex mechanism The junction gate solenoid drops the junction gate, and the original is guided to the inverter roller. When the trailing edge of the original has passed the exit roller, the junction gate solenoid turns off and the inverter roller changes direction. The original is fed back into the ARDF and the other side is scanned. After scanning the second side, the machine inverts the original again, so that it is stacked correctly in the exit tray. 70 Exit roller Inverter roller Junction gate

71 Exercise Go to the machine remove the back cover of the ARDF and have a look to the mechanical parts. Read the service manual on how to remove the back cover. 71

72 Ricoh Academy Europe 6.3 Scanner 72

73 Overview All scanner optics are included inside one carriage. When you move the carriage, use the drive belt. Do not pull the carriage directly otherwise you get image skew. 73 ARDF/Platen cover open sensor Exposure glassADF scan glass Scanner carriage HP sensor Scanner carriage Scanner drive belt Scanner drive motor

74 Inside the carriage The light source is an LED array. Light from the LED board goes to the original via the two reflectors. To make sure that enough light reaches the left and right edges of the original, the elements in the LED array are more closer to each other at the ends than at the center. 74 CCD 2nd Mirror 4th Mirror LED Board Reflectors 1st Mirror 3rd Mirror 5th Mirror Optical pathLens

75 Drive The drive belt moves the carriage along the guide rod. The actuator for the HP sensor is on the underside of the carriage. 75 Scanner drive motor Guide rod Scanner drive belt Carriage HP sensorScanner carriage

76 Moving the carriage by hand When you must move the carriage by hand, move the belt, as shown below. 76

77 Ricoh Academy Europe 6.4 Laser units 77

78 Overview There are two laser units. 1 for Black and Cyan. 1 for Magenta and Yellow. 78

79 Laser unit details Both laser units are physical identical. Dont exchange them because the colour skew adjustments for each colour can be different. This is explained later in this presentation. 79 F-theta lens-2 1st mirrorLD unitF-theta lens-1 2nd mirror Toner shield glass Polygon mirror

80 Laser beam path The scan line is written on the drum from the front end towards the rear of the machine. 80 Collimating lens LD unit

81 Colour skew adjustment The adjusters must be used after installing a new LD unit. There is one for each color. They move the front of the F-theta lens-2 from left to right, seen from the front of the machine. This moves the position of the scan line on the drum, to correct for colour skew. 81 Adjusters F-theta lens-2

82 After replacing a laser unit There are two things to do: Initialize the D-phase data and shading data. See the service manual (Replacement and Adjustment, Laser Optics). Do the color skew adjustment procedure. Explained on the next few slides. 82

83 Colour skew adjustment (1/5) Execute MUSIC (SP2-111-002). After you execute MUSIC, check the adjustment with the following SPs. 2-117-004 (Black) 2-117-002 (Cyan) 2-117-001 (Magenta) 2-117-003 (Yellow) No skew adjustment is required when all SP values are within ±5. When one or more of the SP values is not within ±5, then you must adjust colour skew for any color that has an SP value that is not 0. For example: If 2-117-001 is -4, and the others are +1, no adjustment is necessary. If 2-117-001 is -6, and the others are +1, the adjustment must be done for all four colours. If 2-117-001 is -6, and the others are 0, the adjustment must be done only for magenta. 83

84 Colour skew adjustment (2/5) Open the front cover [A]. Remove the upper cover [B]. Then close the front cover again. Execute MUSIC (SP2-111-002) again. This is because removing the upper cover may have caused the LD units to slip out of alignment. 84

85 Colour skew adjustment (3/5) Adjust the colours that need correction using the knobs shown below. See the procedure in the service manual for details. These adjustments move the L2 F-theta lenses-2 inside the laser units. 85

86 Colour skew adjustment (4/5) This shows one of the four knobs. Rotate each knob corresponding to the value shown in SP2-117-001 to 004. Clockwise: 90 degrees corresponds to changing the SP value by +1 Counterclockwise: 90 degrees corresponds to changing the SP value by -1 A click is felt every 90 degree rotation of the knob. Examples: If the SP value is +6, turn knob [A] in the diagram 6 clicks clockwise. If the SP value is -7, turn knob [A] 7 clicks counterclockwise. 86

87 Colour skew adjustment (5/5) Reassemble the machine. Execute MUSIC (SP2-111-002) Check the SPs (SP2-117-001 to 004). If one or more of them is over ±5 (either positive or negative), repeat the adjustment. The adjustment is finished when all SP values are ±5. 87 Before adjustmentAfter adjustment

88 Exercise Do the colour skew adjustment according to the procedure in the field service manual. 88

91 Drum unit Lubricant is applied by the lubricant brush and spread out by the cleaning blade. At the end of a job, the drum reverses for a short while to remove toner and dust that has adhered to the edge of the blade. Toner removed from the drum is transported to the front of the machine by the toner collection coil. 91 Toner collection coil Lubricant brush Cleaning blade

92 Development unit 92 Toner density sensor Lower agitator Development roller Upper agitator Doctor blade

93 Drive For CMY, there are two motors (drum drive, and development unit drive). For K, there is one motor. A clutch connects this motor to the development unit at the correct time. Never remove gears 3,5 or 7. The phase between these gears are adjusted at the factory. 93 6 12 2 11 1 10 543 9 87

94 Replacement procedures Do not disassemble the PCDUs. There are no service parts for the individual components of the PCDUs. If you are working around the drive area (see the previous slide), mark the positions of the drum phase gears. If these gears come off, it is very difficult to get them back in the correct place, and the machine may have to be replaced. The drive unit is available as a spare part, but it is very difficult to replace. 94

95 PCDU replacement procedure You must release the lock lever and check that the ITB has no tension. 95 Lock lever released Tension released Tension applied

96 Exercise Remove the PCDUs and have a look at the differences between the units. 96

97 Ricoh Academy Europe 6.6 Toner supply 97

98 Overview 98 Toner supply coil AgitatorToner end sensor Shutter ID chip BRB (Bottle Read Board) Toner bottle Toner supply motor

99 Toner supply path Toner is moved into the hopper when the bottle is rotated. The agitator in the hopper pushes the toner towards the toner supply coil and transported into the development unit. Only the colour units have toner end sensors. In the K unit, the ID chip monitors toner end. The machine calculates near end from how much toner is supplied during the life of the bottle. 99 Toner supply coilAgitatorToner end sensor Toner supply motor

100 Toner bottle detection When the BRB board detects an ID chip, the machine detects that the toner bottle is installed. 100 ID chipBRB

101 After replacing the toner supply Set the following SPs (New unit flag) to 1 depending upon the replaced unit. SP3-701-027 (Black) SP3-701-028 (Cyan) SP3-701-029 (Magenta) SP3-701-030 (Yellow) Set the following SPs (Toner supply flag) to 1 depending upon the replaced unit. SP3-510-031 (Black) SP3-510-032 (Cyan) SP3-510-033 (Magenta) SP3-510-034 (Yellow) Exit from the SP mode. Turn the main power off and on. 101

104 Drive The paper transport motor drives the paper feed, registration, and bypass mechanisms through gears and clutches. It also drives the duplex and bypass bottom plate lift mechanisms. 104 Bypass feed clutch Paper feed clutch Registration clutch Paper transport motor

105 Bottom plate lift A rack and pinion mechanism lifts the bottom plate. The motor turns the pinion. The rack pulls the lift arm through a spring. The HP sensor detects when the bottom plate is lifted. The lift motor contains a sensor. The machine uses this sensor and the HP sensor to monitor the amount of lift. 105 Rack and pinionLift motor

106 Bypass bottom plate The bypass bottom-plate is operated by a clutch. When the clutch is energized, drive from the paper transport motor turns the bottom plate cam shaft, through gears. The front cam and the rear cam, lift and lower the bottom plate. The HP sensor monitors the position of the bottom plate. 106 HP sensor Bottom plate cam Bottom plate clutch

107 Bypass tray sensors The paper size sensor detects the size for B5 paper or wider. The paper end sensor detects whether there is paper in the tray. 107 Paper end sensor Paper size sensor

109 Overview 109 1 15 8 7 6 5 4 3 2 9 1413 12 11 1016

110 Image transfer process A typical image transfer belt and paper transfer system is used. 110

111 Image transfer power supply Image transfer bias (to transfer toner from the drum to the ITB) is applied at the four image transfer rollers. Paper transfer bias (to transfer toner from the ITB to the paper) is applied at the ITB drive roller. The paper transfer roller and discharge plate are both grounded. 111

112 ITB contact mechanism This mechanism only exists for CMY. K is always in contact except when the lock lever is released. The ITB contact motor drives this mechanism through a worm gear and a cam. When the cam moves the slider, the image transfer rollers for CMY move up into contact with the OPC drums, or down away from them. If the mechanism is defective, make sure the transfer belt is not in contact with the drum units. This is explained earlier in this presentation. 112 Slider ITB contact sensorITB contact motor ITB contact cam

113 ITB cleaning The ITB cleaning blade removes remaining toner from the ITB. The waste toner transport coil moves the toner towards the front of the machine into the waste toner bottle. The lubricant brush roller applies lubricant to the ITB. 113 Toner transport coil Cleaning blade Lubricant brush roller

114 ID sensors 3 ID sensors are used for Image density detection and MUSIC. If you install a new ID Sensor board, input the values [A] from the barcode sheet into the indicated SPs. 114 ID sensor board

115 Exercise Go to the machine and do the ITB unit and ID sensor removal procedure according to the service manual. 115

116 Ricoh Academy Europe 6.9 Waste toner collection 116

117 Overview The waste toner drops at the front of the bottle. A coil moves the waste toner from the ITB unit, the Y PCDU and M PCDU towards the left-side of the bottle. The agitator makes the surface of the toner level. There is another agitator for toner that arrives from the ITB (see the next slide). Waste toner from the C and K drums drops straight into the bottle. 117

118 Mechanism When the coil rotates, the agitators move the toner towards the rear of the bottle. The bottle full sensor detects when the bottle is almost full, and the machine displays a warning on the screen. After near-full is detected, the machine calculates when the bottle becomes full, and stops operating. 118

119 Replacing the waste toner bottle Move the 5 caps [A] from their storage location on the waste toner bottle to the inlets, so no toner will spill out when you transport the bottle. Dispose of used bottles in accordance with local regulations. 119

120 Ricoh Academy Europe 6.10 Fusing 120

121 Principle This machine uses a Quick Start Up Direct Heating (QSU- DH) fusing system which saves energy and improves print quality. The new fusing unit uses a thin fusing belt which turns freely around the lamp. No heating roller or hot roller. The fusing belt is much thinner than a hot roller, so less electricity is used to reach the fusing temperature. By using a flat fusing pad, fusing is done on a flat surface without uneven pressure from the pressure roller. This means that there is less damage/wrinkling to the paper. This is especially helpful for envelope printing. 121

125 Fusing drive The fusing/exit motor drives the pressure roller. The fusing sleeve turns when the pressure roller rotates. Fusing paper jam is detected by sensors at the entrance and exit of the fusing unit. 125 Fusing motor Fusing entrance sensorPressure roller Fusing sleeve Fusing exit sensor

126 Fusing unit replacement After the fusing unit is replaced you must do the following: Set SP3-701-014 to 1. Exit the SP-mode. Switch the machine off and on. Check SP7-803-016 whether the fusing is reset correctly. 126

127 Fusing sleeve belt replacement The fusing pad must face the pressure roller. The fusing sleeve belt is replaced as an assembly. 127

128 SC 554 If SC 554-00 occurs, there could be temperature damage to the fusing unit. The fusing unit should be replaced, but if it is not damaged, you can continue to use it. In the field service manual there is a separate procedure for SC 554-00. 128

129 SP 5-810 From the flow chart on the previous slide, you can see that a new SP (SP5-810-002) is added. If you do this SP, the machine checks for the fuse for new unit detection, and blows the fuse if it is found. If the fuse is not found and blown, the SP execution fails. SP 5-810-002 is normally only done as part of the countermeasure for SC 554. 129

130 Fuse for new unit detection The fuse is shown below [A]. It is not included in machines shipped from the factory. The fuse is present in fusing units that are installed as service parts, but it is blown immediately after the fusing unit is installed. So, in each case, if you will re-use a fusing unit that has encountered SC554 but is not damaged, you need to get a new fuse and install it like shown below. (part number: M026 4371) 130

131 Exercise Do the pressure roller and sleeve belt assembly removal procedure according to the service manual. 131

132 Ricoh Academy Europe 6.11 Paper exit 132

133 Overview The position of the inverter junction gate determines whether paper from the fusing unit is: Fed out of the machine. Fed towards the duplex feed path. 133 Inverter junction gate Exit/inverter roller Paper exit sensor Fusing exit sensor

134 Components The exit/inverter roller is driven by the paper transport motor. The paper exit sensor controls the timing for the inverter mechanism. 134 Inverter junction gate Exit/inverter roller Paper exit sensor

135 Inverter mechanism When the exit sensor detects the leading edge of the paper, both solenoids turn on. The exit roller rotates in the other direction. The junction gate guides the paper to the upper exit. When the exit sensor detects the trailing edge of the paper, both solenoids turn off. The exit roller rotates in the other direction. The junction gate guides the paper to the duplex feed path. 135

136 Exit/inverter gear train 136 Drive from the paper transport motor Drive to the exit roller Movement by the solenoid

137 Exit unit replacement Make sure that you do NOT release the exit roller drive belt [B] when removing the paper exit unit. If the belt is released and dropped down to the lower part of the machine, you will have difficulty in reattaching it. 137

138 Exercise Remove the exit unit. Follow the instructions in the service manual. 138

139 Ricoh Academy Europe 6.12 Duplex feed 139

140 Overview After the inverter mechanism feeds the paper back into the machine, the paper goes to the duplex feed path. Duplex feed is not possible when the bypass tray is in use. 140 Entrance sensor Duplex rollers Exit sensor

141 Duplex drive The paper transport motor drives the duplex mechanism through gears and the duplex clutch. Two sensors detect paper jams and control paper feed timing. 141 Duplex clutch Paper transport motor

142 Interleaving The order of printing is as follows: Sheet 1, reverse side > Sheet 2, reverse side > Sheet 1, front side > Sheet 3, reverse side > Sheet 2, front side > sheet 3, front side. 142

143 Ricoh Academy Europe 6. Maintenance 143

144 SMC data to SD card All settings (both SP mode settings and UP mode settings) can obviously be printed using SP5-990 (SMC). However, as of 11A, you can also save the SMC onto an SD card (csv format). SP5-992 144 SD slot or Service slot

145 PM parts PCDU: 60K (Black) A4, 5% coverage, 2 pages/job Waste toner bottle: 90K 145

146 Yield parts PCDU (CMY) Replacement at 24k colour prints Replacement at 120k: ITB cleaning unit PTR unit Fusing belt, fusing pressure roller, fusing entrance guide plate, fusing exit guide roller Bypass feed roller Optional paper tray: Separation pad, pick-up roller 146

147 Before performing maintenance Print the SMC logging data with SP5-990-004. To reset the PM counter for each item, you must set SP3- 701-001~20 to 1 before you switch off the machine. After switching on the machine, the PM counters are reset automatically. The developer is initialized automatically. After installing the new items: Make sure that the PM counters for the replaced units are "0" with SP7-803. If the PM counter for a unit was not reset, then reset that counter with SP 7-804. Check the other counters as specified in the After installing the new PM parts procedure. 147

148 Cleaning the ID sensor Clean the ID sensor [B] with a damp cloth. 148

149 Ricoh Academy Europe 7. Replacements & Adjustments 149

150 Fax unit The MBU and FCU are combined into one board. After you replace the FCU, you must transfer the SRAM data from the old FCU to the new board. This is done by connecting the old FCU to the new board with a flat cable. A flat cable is provided with the new FCU service part. The following data will be transferred: TTI RTI CSI bit switch settings RAM address settings NCU parameter settings 150

154 Drive The paper feed motor drives the rollers in the paper tray through two clutches. After the paper has been fed into the machine, the clutches turn off. 154 Paper feed clutch Paper transport clutchPaper feed motor

155 Paper feed This tray uses a feed roller and friction pad system. The paper-end and remaining-paper sensors use the same actuator. 155 Paper end sensor Remaining paper sensor

156 Tray lift mechanism The upward pressure from the bottom plate is adjusted depending on how much paper remains. The bottom plate lift sensor detects the encoder plate. In response to the output from the sensor, the bottom plate lift motor lifts the bottom plate. 156 Bottom plate HP sensor Encoder plate Bottom plate lift sensor
