Page 74
CHAPTER 2 3. Fixing unit protection function The printer has three protective functions to prevent excursion of the fixing heater. • The D-CPU monitors the voltages of the UPPER FIXING ROLLER TEMPERATURE DETEC- TION signal (THRU) and the LOWER FIXING ROLLER TEMPERATURE DETECTION signal (THRL).
Page 75
CHAPTER 2 4. Fixing unit abnormality detection A fixing unit abnormality is detected by the following three circuits: a. D-CPU on the DC controller PCB b. Fixing heater safety circuit (in the power supply circuit) c. Fixing unit abnormality detection circuit (in the power supply circuit) The detection function of each circuit is described below.
Page 76
CHAPTER 2 a. If the D-CPU detects a fixing heater failure If the fixing unit is heated excessively or does not reach the prescribed temperature for some reason or other, the D-CPU deactivates the relay to interrupt the power to the heater and stops sending the signal that drives the fixing heater.
Page 77
CHAPTER 2 c. If the fixing unit abnormality detection circuit detects a failure The fixing unit abnormality detection circuit in the power supply unit detects a broken fixing heater wire, a shorted triac or relay. This printer drives the upper and lower fixing heaters individually and monitors the FXSTS signal after the temperature control starts.
CHAPTER 2 C. High-voltage Power Supply Circuit 1. Outline This circuit applies voltage to the primary charging roller, developing cylinder, primary transfer roller, secondary transfer roller, ITB cleaning roller, and upper fixing roller according to the instructions sent from the microcomputer (M-CPU) on the DC controller PCB. DC voltage or superimposed voltage of AC voltage and DC voltage is applied to the primary charging roller, developing cylinder, and ITB cleaning roller.
Page 79
CHAPTER 2 2. Operation a. Primary charging high-voltage generation circuit This circuit is controlled by the three signals (PRIMARY CHARGING AC BIAS DRIVE signal, PRIMARY CHARGING DC BIAS DRIVE signal, and PRIMARY CHARGING BIAS VALUE CON- TROL signal) sent from the DC controller PCB. The primary charging DC bias and primary charging AC bias are generated in this circuit and applied to the primary charging roller.
Page 80
CHAPTER 2 The DEVELOPING BIAS VALUE CONTROL signal (/DEVPWM) changes the value of the devel- oping bias in the image area (see note). When developing color toner (Y, M, C), the voltage values of both DC and AC are changed. When developing black toner, only DC voltage value is changed (AC voltage is a fixed value).
Page 81
CHAPTER 2 d. Secondary transfer high-voltage generation circuit This circuit is controlled by the three signals (SECONDARY TRANSFER DC POSITIVE BIAS DRIVE signal, SECONDARY TRANSFER DC NEGATIVE BIAS DRIVE signal, SECONDARY TRANSFER BIAS VALUE CONTROL signal) sent from the DC controller PCB. Secondary transfer DC positive bias and secondary transfer DC negative bias are generated in this cir- cuit and applied to the secondary transfer roller.
Page 82
CHAPTER 2 The ITB CLEANING DC POSITIVE BIAS DRIVE signal (/ICLP) controls ON/OFF of the DC positive bias applied to the ITB cleaning roller. The ITB CLEANING DC NEGATIVE BIAS DRIVE signal (/ICLN) controls ON/OFF of the DC negative bias applied to the ITB cleaning roller. The ITB CLEANING AC BIAS DRIVE signal (/ICLAC) controls ON/OFF of the AC bias applied to the ITB cleaning roller.
CHAPTER 2 D. Low-voltage Power Supply Circuit 1. Outline When the power switch (SW6) is turned ON, the AC power is supplied to the low-voltage power supply circuit in the power supply unit. This circuit supplies the power, +24VDC and +5VDC, which are required for the printer, and 3.3/5VDC for the video controller.
Page 84
CHAPTER 2 door switch (SW5) is turned OFF by opening the drum cartridge drawer, ITB unit drawer, toner cartridge door, or delivery door and +24VB, which is always supplied whether SW4 and SW5 are turned ON or OFF. The low-voltage power supply circuit monitors the 5VS signal fed back from the connector PCB to ensure the 5V power supply to the video controller.
Page 85
CHAPTER 2 Note: After completion of print operation, the fan motor is rotated at its full speed for a spec- ified period of time and then stopped (see page 2-35). When the sleep level 2 (deep sleep) command is received, the fan motor is stopped in a specified period of time (about 10 min.) after the fixing temperature control is stopped.
CHAPTER 2 E. Video Interface Control 1. Outline To connect the printer to an external device, such as a host computer, a video controller PCB (interface PCB) must be installed between the printer and the external device. This section explains the kinds of interface signals exchanged between the printer and the video controller PCB, and gives information about the sequence of printer operation making use of interface signals.
Page 87
CHAPTER 2 2. Operation When the power is switched ON, the printer enters the WAIT state. When the printer is ready for operation after the WAIT period, the DC controller sends a READY signal (/RDY) to the video controller to notify it that the printer is ready. When the /RDY signal is “L”...

Page 98
CHAPTER 2 When the /VDATA is “H” to turn OFF the laser, the current enters the resistance (R1117, R1118) instead of the laser diode as RO. The laser current monitor circuit sends back the current to the A/D port in the D-CPU as the LASER CURRENT MONITOR signal (ILM). The D-CPU stops laser emission and notifies the video controller of the laser failure when the input current value exceeds the specified value.

CHAPTER 2 2. Electrostatic latent image formation block a. Outline The electrostatic latent image formation block consists of a drum cartridge (photosensitive drum, a primary charging roller, a waste toner container, a drum cartridge memory, a toner feed plate and a stirrer). The photosensitive drum, toner feed plate and stirrer are driven by the drum motor (M4).
Page 106
CHAPTER 2 b. Drum cartridge memory The drum cartridge memory (EEPROM) has a read area and a read/write area. The read area is exclusively for reading and stores the identification code for the drum cartridge and threshold value for the drum cartridge life. The DC controller reads data from or writes data into the read/write area at the specified timing to check the drum cartridge life and waste toner full.
Page 107
CHAPTER 2 d. Waste toner full detection The waste toner full is detected by the waste toner full sensor (PS13). PS13 consists of a light emitter and a light receiver. The light from the emitter passes through the light guide and enters the detection port of the drum cartridge. The light entered the port passes through the cartridge when the waste toner around the detection port is scraped off by the stirrer.
Page 108
CHAPTER 2 3. Development block a. Outline The development block consists of four toner cartridges and a developing rotary in which the cartridges are installed. The developing rotary is turned by the developing rotary motor (M3). The developing rotary contains Bk (black), M (magenta), C (cyan), and Y (yellow) toner cartridges, each of which faces the photosensitive drum in sequence.
Page 109
CHAPTER 2 b. Developing rotary control When it receives a PRINT signal (/PRNT) from the video controller, the DC controller outputs a DEVELOPING ROTARY MOTOR DRIVE signals, turns the developing rotary motor (M3) ON, and rotates the developing rotary. When the developing rotary turns to the prescribed position, the DC controller stops the developing rotary motor and stops the developing rotary.

CHAPTER 2 c. Toner cartridge contact/separation Toner cartridge push cam function Photosensitive Developing This function brings the developing cylinder drum rotary shaft closer to the photosensitive drum by push- Slider ing the toner cartridge at the time of devel- Toner cartridge opment.
Page 111
CHAPTER 2 d. Toner cartridge position (contact/separation) detection function This function detects the position (contact/separation) of the developing cylinder in the toner cartridge which is brought closer to or further from the photosensitive drum by the toner car- tridge contact/separation function (see page 2-52). The toner cartridge position is detected by the toner cartridge contact sensor (PS11) in the rotary drive unit.
Page 112
CHAPTER 2 e. Toner level detection/toner cartridge detection This function detects the remaining toner level in the toner cartridge and the presence of the toner cartridge in the developing rotary. The toner level and the presence of the toner cartridge are detected by the toner level sensor (PS12).
Page 113
CHAPTER 2 4. Transfer block a. Outline The transfer block consists of an ITB unit, a secondary transfer roller unit, and an Intermediate transfer belt contact unit. This block transfers the toner transferred from the photosensitive drum to the paper and cleans the residual toner. The intermediate transfer belt is driven by the drum motor (M4).
Page 114
CHAPTER 2 b. Home position detection The home position of the intermediate transfer belt is detected to transfer four color toners to the intermediate transfer belt precisely and align the leading edge of print paper with the lead- ing edge of the image. There are four holes (home position detection holes) in the area outside the toner transfer area on the intermediate transfer belt at equal intervals (see Fig.2-4-12).

CHAPTER 2 c. ITB unit life detection This detector determines whether the end of the ITB unit life has been reached. The ITB counter unit on the side of the ITB unit conducts the ITB unit life detection. The ITB counter unit consists of 12 gears with different numbers of teeth and the ITB unit life detection lever.
Page 117
CHAPTER 2 d. ITB cleaning roller contact/separation control Normally the ITB cleaning roller is detached from the intermediate transfer belt. This operation presses the ITB cleaning roller against the intermediate transfer belt to clean the belt. (See page 2-69 for details of ITB cleaning.)

Page 118
CHAPTER 2 e. Secondary transfer roller contact/separation control Normally, the secondary transfer roller is detached from the intermediate transfer belt. This operation presses paper against the intermediate transfer belt with the secondary transfer roller at the time of secondary transfer. (See page 2-67 for details of secondary transfer.) The DC controller sets the SECONDARY TRANSFER ROLLER CONTACT CLUTCH DRIVE sig- nal (TR2CLON) to “L”...
Page 119
CHAPTER 2 ITB unit contact/separation control Normally, the intermediate transfer belt is separated from the photosensitive drum. (Note) This operation presses the belt against the drum by moving the ITB unit contact lever at the begin- ning of print operation. When the fixing unit temperature reaches the print temperature at the beginning of print operation, the DC controller sets the ITB UNIT CONTACT CLUTCH DRIVE signal (/ITBCLON) to “L”...
CHAPTER 2 C. Print Process The printing process can be divided into six major blocks. 1. Electrostatic latent image formation block Step 1 Primary charge Step 2 Scanning exposure 2. Developing block Step 3 Development 3. Transfer block Step 4 Primary transfer Step 5 Secondary transfer Step 6 Separation 4.
Page 121
CHAPTER 2 1. Electrostatic latent image formation block This block has two steps which together produce a pattern of electrical charges on the photo- sensitive drum. At the end of the block, negative charges remain in the unexposed “dark” areas. Charges are absent from “light”...
Page 122
CHAPTER 2 Step 2 Scanning exposure When the laser beam scans the drum surface, it causes the charge to be neutralized in areas struck by the laser beam. Areas on the drum with no charges form the electrostatic latent image. Laser beam Unexposed area Exposed area...
Page 123
CHAPTER 2 2. Development block Development places particles of toner onto areas of the drum that have been cleared of charges by the laser beam. This makes a visible image. This printer uses the toner projection develop- ment method with a magnetic single-component black toner and non-magnetic single-compo- nent color toner.
Page 124
CHAPTER 2 3. Transfer block In the transfer block, the toner image is transferred from the drum surface onto the intermedi- ate transfer belt and then onto the paper. Step 4 Primary transfer A positive charge is applied to the primary transfer roller of the intermediate transfer belt to charge the intermediate transfer belt positively.
Page 125
CHAPTER 2 Step 5 Secondary transfer The toner on the intermediate transfer belt is transferred to the paper in this step. The paper is pressed against the intermediate transfer belt when the secondary transfer roller contact cam lifts the secondary transfer roller. The DC bias (positive) is applied to the secondary transfer roller and the toner on the inter- mediate transfer belt is transferred to the paper.
Page 126
CHAPTER 2 Step 6 Separation The elasticity of the paper causes it to separate from the drum. To decrease the electrostatic adhesion of the paper and facilitate separation, the charge on the back of the paper is reduced by the static charge eliminator after transfer. Intermediate transfer belt Print paper Charge eliminator...
Page 127
CHAPTER 2 4. ITB cleaning block This block consists of two steps and moves the residual toner (note) on the intermediate trans- fer belt to the photosensitive drum to clean the intermediate transfer belt. Note: Residual toner In the secondary transfer block, the toner on the intermediate transfer belt is transferred to the paper, but some toner remains on the intermediate transfer belt.
Page 128
CHAPTER 2 Step 8 ITB cleaning In this block, the residual toner charged uniformly by ITB cleaning roller in step 7 is moved from the intermediate transfer belt to the photosensitive drum. Different levels of biases are applied to the photosensitive drum and the intermediate trans- fer belt to produce a difference between the potentials of the photosensitive drum and interme- diate transfer belt and move the residual toner from the intermediate transfer belt to the photo- sensitive drum.
Page 129
CHAPTER 2 5. Photosensitive drum cleaning block In the transfer block, not all the toner is transferred to the paper. Some remains on the photo- sensitive drum. Also, the residual toner on the intermediate transfer belt is carried back to the photosensi- tive drum by ITB cleaning.
Page 130
CHAPTER 2 6. Fixing block The toner image transferred onto the paper in the transfer block is held only by electrostatic attraction, so even a light touch will smear the image. In the fixing block, the four color toners are melted and mixed by heating the paper and applying pressure to make a permanent image.
CHAPTER 2 D. Image Stabilization Control 1. Outline This printer conducts the stabilization density control in order to prevent variations in the image density caused by environmental changes, deteriorated photosensitive drum or toner. The image stabilization control consists of the image density ajustment control and the gra- dation adjustment control.
Page 132
CHAPTER 2 2. Density detection function This function detects the density of the density pattern formed on the photosensitive drum with the density sensor (PS14) during the image density adjustment control and the gradation adjustment control. The PS14 is placed in the drum cartridge drawer unit and consists of an density detection circuit, LED, photodiode 1 and 2.
CHAPTER 2 V. PICK-UP/FEED SYSTEM A. Outline When the /PRNT signal is sent to the DC controller by the video controller and the scanner motor is put in the READY mode, the DC controller starts the print operation. For cassette feed- ing, a sheet of paper is picked up by the cassette pick-up roller and is fed by the feed rollers.
Page 134
CHAPTER 2 The printer switches the feeding speed between three levels according to the media specification command sent from the video controller. The media types and feeding speeds by fixing/feeding mode are listed below. The feeding speed is switched when the paper is refed from the registration roller. Table 2-5-1 Feeding mode OHT mode...
CHAPTER 2 B. Paper Pick-up 1. Cassette pick-up a. Outline The presence of the paper on the cassette is sensed by the cassette paper sensor (PS8). The paper size and the presence of a cassette are detected by three paper size detection switches (SW801 to 803).

Page 137
CHAPTER 2 b. Multi-feed prevention mechanism For cassette pick-up, this printer uses a separation roller to prevent simultaneous feeding of sev- eral sheets. Normally, the separation roller is imparted with rotational force reverse to the feed roller which rotates in the direction of paper feed. However, as the separation roller has a torque limiter, it rotates with feed roller 1 through transmission of its rotational force via the trans- ported paper.
Page 138
CHAPTER 2 2. Multi-purpose tray pick-up a. Outline The presence of the paper on the multi-purpose tray is sensed by the multi-purpose tray paper sensor (PS4). When it detects the home position (HP1) for the first color image formation after receiving the PRINT signal (/PRNT), the DC controller drives the pick-up motor (M2).
Page 139
CHAPTER 2 the paper within a specified period of time after detection of the ITB HOME POSITION DETEC- TION signal (/ITBHP), the DC controller conducts the pick-up operation one more time. If the registration paper sensor cannot detect the leading edge of the paper after the 2nd pick-up oper- ation, the DC controller assesses a pick-up delay jam and reports it to the video controller.
Page 140
When the OHT is detected, the DC controller switches the printing mode to the OHT mode and changes the feed speed after refeeding. The Canon original OHT (OHT T-H1) cannot be used for this printer. (See note) When the OHT T-H1 is picked up, the DC controller recognizes it as an unusable OHT by detecting the marking on the OHT T-H1 with the PS301, reports it to the video controller, and stops the print- er.
Page 141
CHAPTER 2 3. Paper size detection The paper size and presence of the cassette are detected by the paper size detection switches (SW801 to 803). Combinations of paper size detection switches are listed in Table 2-5-2. Table 2-5-2 Cassette paper size detection switch Paper size SW801 SW802...
CHAPTER 2 C. Feed Unit 1. Outline The feed unit consists of the secondary transfer roller, feed belt, and feed support unit and feeds the paper from the registration roller to the fixing unit. The secondary transfer roller and the feed belt are driven by the fixing motor (M1). The sec- ondary transfer roller is lifted by the secondary transfer roller contact clutch (CL4) at the time of transfer.
CHAPTER 2 D. Fixing and Delivery Unit 1. Outline The upper fixing roller and the fixing delivery roller of the fixing unit and the face-down delivery roller are driven by the fixing motor (M1). The lower fixing roller is driven by the upper fixing roller.

Page 145
CHAPTER 2 2. Automatic fixing unit pressure OFF function This function turns OFF the fixing roller pressure to improve jam clearance and to prevent per- manent deformation of the rollers caused by the pressure applied to the same areas of the rollers for a long period of time.
Page 146
CHAPTER 2 The ON/OFF status of the fixing roller pressure is detected by the fixing unit pressure sensor (PS6) located outside the fixing unit. When the fixing roller pressure is turned ON, the pressure detection cam, which is located on the same shaft as the fixing pressure cam facing the opposite direction, pushes the pressure sensor flag.
CHAPTER 2 E. Paper Jam Detection The following paper sensors are provided to detect whether paper is present and whether the paper is fed normally: • Registration paper sensor (PS2) • Delivery paper sensor (PS7) The microcomputer (M-CPU) determines if paper jam has occurred by checking for the presence of paper in the sensor at the timing stored in the CPU.
CHAPTER 2 VI.VIDEO CONTROL SYSTEM A. Video Controller PCB 1. Outline The video controller receives print data consisting of code data or image data sent from the exter- nal device (host computer, etc.) via the interface cable. Print data including contents specified by the control panel is analyzed, processed and con- verted into dot data in the video controller.
Page 149
CHAPTER 2 g. Flash ROM (U10) The Flash ROM has a memory capacity of 1MB and stores self test program which is executed while booting up the system. h. AIR (U52) The AIR is used for processing data which is sent to the video interface. Smoothing is processed in the AIR.
CHAPTER 2 B. Control Panel 1. Outline The control panel of this printer consists of 2 LEDs, 2 LCDs and 8 keys. The control panel is connected to the video controller PCB via the intermediate PCB and per- forms the following functions. a.
CHAPTER 2 C. Self Test The printer has a function that executes the self diagnostics program stored in the video con- troller when the power is turned ON to check the state of the video controller and control panel. This function is called self test. Normally, when the power is turned ON, START SELF-TEST appears in the message area and the POWER-UP diagnostic set is run after the CPU initialization completes.

CHAPTER 2 2. Reversing operation On receiving a duplexing unit specification command sent from the printer, the duplex driver PCB turns ON the delivery deflector solenoid (SL3102). As a result, the delivery deflector is moved and the paper is fed into the duplexing unit. Then, the reversing motor is rotated counter clockwise and the paper is fed into the reversing unit.
Page 162
CHAPTER 2 3. Side registration adjustment The duplexing unit conducts side registration adjustment so that the center of the paper in the horizontal direction matches the center of the printable area on the intermediate transfer belt when the second side is printed. To adjust the side registration, the side registration guides are pressed against both sides of the paper.
