    Ti-P1 Training M109 Service Training Detailed Section Descriptions Image Creation Slide 52 This section explains how a latent image is written on the drum.
  • Page 53 Ti-P1 Training Overview An LED array [1] writes the latent image on the OPC [3]. Each OPC (K, C, M, Y) has its own LED array. These arrays are identical. A spacer [2] on the drum keeps the LED array at the correct distance from the OPC for correct focus.
  • Page 54 Ti-P1 Training Components of the LED Array The LED array consists of the following parts. 1. Sheet 2. Base 3. LED board 4. Frame 5. SLA (Self-focusing Lens Array) The LED array is replaced as one complete unit. The individual components shown above cannot be replaced in the field.
  • Page 55 Ti-P1 Training Detailed Structure of the LED Array Row of LEDs Self-Focusing Lens Array OPC Drum Tiny LEDs capable of creating images at 1200 dpi are arranged in a line. Light beams emitted by the LEDs are focused using the Self-focusing Lens Array (SLA), creating an image on the OPC drum.
  • Page 56 Ti-P1 Training Notes Concerning the LED Array Image position adjustment Horizontal (main scan): Adjusted by moving the image position Vertical (sub scan): The timing for the start of writing is changed. There are no mechanical adjustments. Start timing can be adjusted LED light intensity An EEPROM on the LED head contains data which controls the light intensity of each element.

  • Page 57: Troubleshooting Notes

    Ti-P1 Training Troubleshooting Notes The LED heads are the same for all CMYK colors. So it is possible to find which LED head has the problem by swapping them with one another. The LED spacer contacts the OPC to keep the correct distance between the LED head and the drum for focusing.
  • Page 58 Ti-P1 Training Removing an LED Head After you open the upper inner cover, cover the PCDUs with a sheet of paper, to prevent foreign objects from falling into the PCDUs. Slide 58 If you are in a training class, or have access to the machine while doing this course, look through these next few slides before you do the procedures, to make sure you are familiar with these important points.

  • Page 64: Toner Supply Mechanism

    Ti-P1 Training Toner Supply Mechanism When the toner supply clutch turns on, a coil in the toner cartridge rotates to transfer toner to the bottle exit and then the PCDU. Toner which falls into the PCDU is transferred to the development section by the upper mixing coil [1].
  • Page 65 Ti-P1 Training Toner Near End (TNE), Toner End (TE) The TE sensors are mounted on the LED arrays. They monitor toner supply through the TNE detection windows in the PCDUs. TNE is detected when the TE sensor detects non-supply of toner.
  • Page 66 Ti-P1 Training PCDU Drive The PCDUs are driven by the drum motor (K) [1], and the drum motor (CMY) [2]. Slide 66 No additional notes...
  • Page 67 Ti-P1 Training Drum Charge and Cleaning This machine uses a charge roller [1]. The charge roller gives the drum surface a negative charge. The machine automatically controls the charge roller voltage when process control is executed. The charge roller cleaner [2] which always touches the charge roller, cleans the charge roller.
  • Page 68 Ti-P1 Training Development The development mechanism contains the development roller [1], the toner supply roller [2], and the development blade. The toner supply roller [2] provides the development roller [1] with toner. The development blade [3] keeps the toner attached to the development roller [1] flat.
  • Page 69 Ti-P1 Training Mixing The toner moves as shown in the above drawing. The upper mixing coil [1] moves the toner to the left side. The lower mixing coil [2] moves toner to the right side. Finally, the toner supply roller [3] supplies toner to the development roller [4].

  • Page 70: Waste Toner Collection

    Ti-P1 Training Waste Toner Collection Toner waste within each PCDU is collected by the waste toner collection coil [7] and sent down to the waste toner bottle. Slide 70 The waste toner collection mechanism will be explained in more detail later.
  • Page 71 Ti-P1 Training New PCDU Detection A three-point terminal on the side of the cover detects when a new PCDU is inserted. If a new PCDU comes into contact with the terminal, a fuse resistor is opened, and the machine detects the new PCDU. When either the user or technician installs a new PCDU, the counter resets automatically.
  • Page 72 Ti-P1 Training M109 Service Training Detailed Section Descriptions Paper Feed Slide 72 This section explains how paper is fed through the machine.
  • Page 73 Ti-P1 Training Overview The machine has a paper tray and a bypass tray. 1. Paper Feed Roller 2. Friction Pad 3. Bypass Feed Roller 4. Bypass Friction Pad The rollers are replaced by technicians only. They are not part of the user PM procedure.
  • Page 74 Ti-P1 Training Drive To start paper feed, the machine turns on the paper feed clutch, and the paper feed roller rotates. The friction pad ensures that only the top sheet is fed. When the paper activates the registration sensor, the paper feed clutch turns off.

  • Page 75: Paper End Detection

    Ti-P1 Training Paper End Detection If the tray becomes empty, a feeler enters a cutout in the bottom plate, and the paper end sensor at the other end of this feeler turns on. Slide 75 No additional notes...

    Ti-P1 Training Adjustable Cassette When shipped from the factory, sizes up to A4 SEF can be loaded in the cassette. To support paper sizes larger than A4 SEF, unlock the tray extension lock ([1] in the diagram on the left) to extend the tray, and then place the paper feed cover on the tray.

  • Page 77: Paper Size Detection

    Ti-P1 Training Paper Size Detection The paper size switch detects actuators attached to the paper size dial. The customer must select the correct paper size with this dial. Slide 77 No additional notes...
  • Page 78 Ti-P1 Training Bottom Plate Lift When you slide the paper feed tray into the unit, the bottom plate arm [1] slides along the sloping guide of the main frame, and then the bottom plate is pushed upward by the spring. As a result, the lifted bottom plate presses the sheet on the top of the stack up against the paper feed roller.

  • Page 79: Optional Paper Tray Unit

    Ti-P1 Training Optional Paper Tray Unit The main differences from the standard tray are: The paper size dial rotates in a different manner. There is a lever to change between thick paper and thin paper. It is operated by sliding two green tabs in the base.
  • Page 80 Ti-P1 Training Bypass Feed Bottom Plate Mechanism The bottom plate has an automatic lifting system. When the paper feed motor rotates in reverse, a one-way clutch transfers the drive to the bottom plate lifting system of the bypass tray. A cam (on the left as you face the machine) starts rotating to lift the bottom plate up and down.

  • Page 81: Bypass Feed

    Ti-P1 Training Bypass Feed Bypass feed uses a feed roller and friction pad mechanism. 1. Bypass Paper End Sensor 2. Bypass Feed Roller When paper is loaded into the tray, the end sensor turns on (the light beam passes through). When the sensor is on, the bottom plate goes down.

  • Page 85 Ti-P1 Training Stopper Gear When the duplex inverter solenoid turns on, the stopper gear engages. The stopper gear stops the inverter roller from rotating but the fusing unit continues to rotate. This mechanism is necessary because the fusing motor drives the inverter roller, but there is no electromagnetic clutch.

  • Page 86: Solenoid Operation

    Ti-P1 Training Solenoid Operation This diagram shows how the solenoids switch drive between the various gears during different phases of the feed-out/inverter operation. Slide 86 No additional notes...

    Ti-P1 Training M109 Service Training Detailed Section Descriptions Image Transfer Slide 89 This section explains how the developed image is transferred from the drum to the paper.
  • Page 90 Ti-P1 Training Overview The transfer section consists of three units: the Image Transfer Unit [1], the Image Transfer Belt Cleaning Unit [2], and the Transport Unit [3]. Slide 90 No additional notes...

  • Page 91: Image Transfer Belt Unit

    Ti-P1 Training Image Transfer Belt Unit The ITB motor [2] drives the ITB drive roller [3] via a gear to drive the image transfer belt. The image transfer belt rollers [1] apply transfer bias to pull toner from the photoconductor to the paper. Slide 91 No additional notes...
  • Page 92 Ti-P1 Training Transfer Belt Contact Mechanism For monochrome printing, the image transfer belt is disengaged from the color drums. The transfer belt contact sensor [1] detects the status of the image transfer belt. The transfer belt contact clutch [3] transfers the drive from the transfer motor [4], and drives the mechanism through a cam [2], to move the transfer belt into contact or away from the color drums.
  • Page 93 Ti-P1 Training Belt Guide Roller Belt Guide Roller In previous models, this roller was inside the ITB unit. However, for this machine, there is no room inside the unit, so it is added at the location shown above. This roller prevents the belt from moving to the left or right on the axis of the drive roller.

  • Page 94: Transfer Belt Cleaning

    Ti-P1 Training Transfer Belt Cleaning The transfer cleaning blade [1] removes remaining toner from the belt surface. The waste toner transport coil [2] carries this toner to the left side of the ITB unit. Slide 94 No additional notes...
  • Page 95 Ti-P1 Training Paper Transfer Roller Unit The bias applied to the paper transfer roller [2] pulls the toner off the ITB and onto the paper. The paper transfer roller is always pressed into contact with the ITB by a spring [4]. When a sheet of paper goes between the transfer roller and the transfer belt, the transfer roller turns with the paper.

  • Page 96: Transfer Roller Cleaning

    Ti-P1 Training Transfer Roller Cleaning Toner may transfer to the roller surface following a paper jam or if the paper is smaller than the image. Periodic cleaning of the roller is required to prevent this toner from migrating back to the rear of new printouts. The machine cleans the roller at the following times: After initial power on.

  • Page 97: Paper Separation

    Ti-P1 Training Paper Separation Power Pack Power Pack (Separation) During paper transfer, the transfer roller [A] applies a static charge to the paper [B]. The electric field generated by the discharge plate [C] grounds any remaining static charge after passing the transfer roller unit. Slide 97 No additional notes...
  • Page 98 Ti-P1 Training New ITB Unit Detection If the machine detects an unbroken fuse [1] immediately after the ITB unit is installed, the machine blows the fuse, and resets the life counter for the ITB. Immediately after this, the machine detects a blown fuse, and the life counter starts.
  • Page 99 Ti-P1 Training Putting the ITB Unit Back in the Machine Before you install the image transfer belt, make sure that the white lever [A] is pulled out to the position shown in this photo.

  • Page 104 Ti-P1 Training Overview This machine uses a QSU (Quick Start Up) type of fusing unit. Two fusing lamps [5] inside a pipe [10] heat a fusing belt [9]. This type of fusing saves energy and allows the use of a wider range of paper types than a traditional fusing unit.
  • Page 105 Ti-P1 Training Quick Start-up (QSU) System 1. Heating Pipe Conducts heat from the fusing lamps to the fusing belt. 2. Fusing Belt Rotates by friction with the pressure roller. The space between the heating pipe and the fusing belt is lubricated to reduce friction, so that the belt will rotate smoothly.

    Ti-P1 Training Fusing Temperature Control Non-contact Thermistor Thermostats Contact Thermistors Thermostats and a non-contact thermistor monitor the fusing belt temperature. Two contact thermistors monitor the pressure roller temperature. The thermostat is a safety switch. Slide 109 No additional notes...
  • Page 110 Ti-P1 Training Fusing Temperature Control Warming-up Mode Fusing warm-up begins after the machine power is switched on. The fusing lamps heat without roller rotation until the temperature reaches the “pre-rotation start temp.” There is no roller rotation, in order to heat the lubricant between the heating pipe and the fusing belt so that the pressure roller rotation will move the belt.
  • Page 111 Ti-P1 Training Fusing Temperature Control Print Mode The fusing temperature increases to the “print ready temperature”, and printing starts. To reduce energy consumption, the fusing lamps turn off before the last sheet of paper passes completely through the fusing nip band. After printing, the roller continues to turn, to prevent temperature overshoot after printing.
  • Page 112 Ti-P1 Training Fusing Temperature Control Wait Mode The fusing lamps and the fusing motor turn OFF after a certain time passes after the temperature has fallen to the print ready temperature. At regular intervals, the fusing motor rotates for a short time at slow speed. The fusing motor stops when the machine is in Sleep Mode.

  • Page 114 Ti-P1 Training Overview Toner waste from the PCDUs is carried to the waste toner duct [1], and then to the front of the unit by a coil, and from there, it is moved down to the waste toner bottle. Toner waste from the ITB Unit is carried to the left side of the unit by the ITB waste toner collection coil [2] and then down to the waste toner bottle [4] via the same opening [3] as used for toner waste from the PCDUs.
  • Page 115 Ti-P1 Training Drive The ITB waste toner collection coil [2] is driven via the drive roller in the image transfer unit. The coil in the waste toner duct [1] is driven via the gear on the left of the image transfer unit. The coil inside the waste toner bottle distributes the toner evenly inside the bottle.

  • Page 116: Waste Toner Bottle Set Sensor

    Ti-P1 Training Waste Toner Bottle Set Sensor The waste toner bottle set sensor [2] detects the presence of the waste toner bottle [4]. There is no bottle replacement detection feature. If the bottle full sensor is off and the bottle set sensor is on, the machine indicates that the waste toner bottle is usable.

  • Page 117: Waste Toner Bottle Full Sensor

    Ti-P1 Training Waste Toner Bottle Full Sensor When waste toner exceeds a certain amount, the rubber portion on the inner part of the waste toner bottle swells. This exerts pressure on the feeler [1], and the waste toner bottle full sensor [3] is turned on.
  • Page 118 Ti-P1 Training Toner Bottle Full The pixel count corresponds to a number of sheets that can be printed after indicating near full. However, these are reference values based on certain specified machine use conditions. Normal: 625 pages Notify Later: 375 pages Notify Sooner: 875 pages The default is Normal.
  • Page 119 Ti-P1 Training Lubricant A small amount of yellow toner is applied to the rubber component shown above with a red circle. Do not touch this rubber, or you may remove the lubricant. If you do wipe it off, apply some yellow toner.

IBACC changes the response so that it is more linear, as shown by the blue line.
  • Page 124 Ti-P1 Training TM (ID) Sensor Below the image transfer belt [1], there are two TM (ID) (Toner Mark) sensors. These are used for MUSIC. They also act as ID sensors for use during process control and IBACC. Note that the sensor seen on the left [A] (as viewed from the front of the machine) is called the right TM (ID) sensor (TM sensor: R), and the one on the right [B] is called the left TM (ID) sensor (TM sensor: L).
