Engine controller is the circuit to control the operation sequence of the host machine and it is
■■Overview
controlled by the CPU inside the engine controller. When the Power Switch (SW1100) is turned ON and DC power is supplied through the low
The Main Controller receives print information from the Reader and external equipment (computer, etc.). Video data is created from the received print information, and is sent to the Engine Controller. There are 2 types of print information from the external equipment: engine command data to exchange the status or unique information of a printer and dot data for printing.
voltage power inside engine controller, CPU starts the printer operation control. Then, CPU drives the loads such as laser diode, motors and solenoids etc. according to the image data that is input by the main controller when status becomes stand-by mode. The following is the block diagram of this circuit. Engine controller
In the case of receiving dot data, video data is created and is sent to the Engine Controller. In the case of receiving engine command data, printer status is returned to the external equipment after communicating with the Engine Controller. READER

●● Original Detection There are two types of original detection in this equipment. 1,Original Presence / Absence Detection Detected by DS (Document Sensor) Setting the original onto the original tray pushes up the actuator, activating (light shielded =>light transmitted) the DS, and resulting in detection of the presence of original. 2,Detection of the End of the Original Detected by the DES (Document End Sensor) The leading edge of the original that is fed pushes up the actuator, activating the DES (light shielded =>light transmitted) and resulting in detection of the reach of the leading edge of original. Furthermore, when the trailing edge of the original passes the actuator position, the actuator returns to the original position, inactivating the DES (light transmitted => light shielded). The trailing edge of the original is detected by this mechanism. The original length that can be scanned with this equipment is less than 400 mm. Passing of the original longer than this results in jam stop. The original length is calculated by the time it takes from detection of the leading edge of the original to detection of the trailing edge of the original.

Step 2: Laser beam exposure
This block is comprised of two steps and forms static latent images on the photosensitive drum. When the final step of this block completes, negative charge remains at dark areas on the drum surface where laser beam has not been exposed, and negative charge is eliminated
In this step, static latent images are formed on the photosensitive drum with laser beam. When laser beams are scanned on the photosensitive drum negatively charged, bright areas lose their charges, eliminating negative potential on the surface of the photosensitive drum; on those portions, static latent images are formed.

Toner Cartridge ■■Toner Level Detection Toner level is detected by the Toner Sensor (Magnetic Sensor). When a Toner Cartridge is installed, the Toner Sensor contacts with the lower side of the cartridge and it converts the magnetic changes in the cartridge into voltage. Then, MPU of DCNT PCB compares the output voltage of the Toner Sensor with the reference value to detect the toner level. Toner level detection is performed at startup of the Main Motor. The toner level detection sequence starts after the Main Motor is started up and stabilization time (200msec) has passed. The toner level detection sequence continues until the Main Motor stops. There are following 2 types of toner level detection sequence: sequence at warm-up rotation when opening door or turning ON the power, and sequence at normal rotation.

The "detection temperature of the Thermistor high temperature detection 2" is set to 195 deg C when the target control temperature is 180 deg C or less. When the target control temperature is above 180 deg C, it is set to "target control temperature + approx. 15 deg C". 8) Thermistor low temperature detection 2)
2) Initial Thermistor open detection When temperature of the Fixing Assembly does not exceed 35 deg C within 1.48 sec after the start of temperature control at warm-up rotation temperature control or at cleaning mode, it is judged as Thermistor open failure. 3) Short circuit of Thermistor/abnormal high temperature detection When temperature of the Fixing Assembly is 220 deg C or higher for 30 consecutive times by monitoring the temperature for every 5 msec, it is judged as Thermistor short circuit failure. In addition, this function also doubles as abnormal high temperature detection function of the Fixing Assembly. 4) Abnormal low temperature detection After temperature of the Fixing Assembly exceeds 50 deg C at least once, monitor temperature of the Thermistor (TH1) for every 5 msec. It is judged as heater abnormal low temperature when the following condition is detected 240 consecutive times: the temperature is 100 deg C or lower while paper is at fixing nip, or it is 55 deg C or lower
Temperature of the Thermistor (TH1) is monitored for every 200 msec when paper is at fixing nip during the Fixing Assembly control. When the temperature is lower than 135 deg C (110 deg C), increase the value of low temperature detection counter by 1 (+1). When it is 135 deg C (110 deg C) or higher, decrease the value by 1 (-1). When the value of low temperature counter becomes +150, it is judged as Thermistor low temperature failure. The default and minimum value of low temperature detection counter is 0. 9) Frequency detection circuit error (230V models only) When frequency measurement is not completed within 3255 msec after the completion of previous frequency measurement, it is judged as frequency detection circuit error. 10) Thermistor high temperature detection 3 Temperature of the Thermistor (TH1) is monitored every 5 msec, and if the temperature is equal or higher than "detection temperature of Thermistor high temperature detection 2 + approx. 15 deg C" more than 30 consecutive times, it is judged as a Thermistor high temperature failure.

■■Throughput Down Control
Paper wrinkle/ curl prevention mode
The machine reduces throughput by increasing the paper interval to prevent the temperature rise at the edge of the Fixing Heater (H1) during continuous printing of small size paper (up to 271 mm long and 189.6 mm wide), and of the Delivery Assembly during large volume continuous printing. Lengthening the paper interval allows the Fixing Heater to cool enough to prevent the temperature rise of the Fixing Assembly roller edge and Delivery Assembly.
●● Throughput Down Sequence If the temperature continues to rise after continuous printing of 20 sheets with "plain paper" or "plain paper L" fixing mode at 400 dpi resolution, throughput is reduced for the remainder of the job.

Pickup Feed System
The pickup and feeding system executes pickup and feeding of papers and is composed of the Main Motor (M1), Pickup Solenoid (SL1), and rollers. In this equipment, pickup from the pickup tray is available. There is only a face-down delivery.
Overview
Papers set on the pickup tray are fed by the pickup roller. The papers are fed to the photosensitive drum, the transfer charging roller, the fixing sleeve unit, the pressure roller and

F-2-27
Whether jam occurs or not is judged according to whether a paper is absent/present on the sensor at the check timing that has been stored in the CPU of the engine controller.
NOTE: The above 1490 (2235) msec value accounts for the 126.26 mm distance from the Paper Leading Edge Sensor (PS751) to the Fixing Delivery Sensor (PS701), plus 40 mm margin. Since the distance from the fixing nip to the Fixing Delivery Sensor (PS701) is 22.9 mm, the length of wrapping from the leading edge is 62.9 mm. Since one lap of the fixing film is 18.2 pi (57.2) mm, the wrapping is longer than one lap. However, allowing for paper arch, sensor accuracy and heavy paper feeding capability, etc., the value cannot be further reduced.
When the engine controller judged that jam has occurred, print operation is stopped and jam occurrence is noticed to the main controller.
NOTE: Jam detection timing may differ for 400 dpi and 600 dpi printing. In such a case, setting values applicable to 600 dpi printing are indicated in parentheses following those for 400 dpi printing.

Image Faults ■■Smudged/Streaked ●● Bleeding (smear) occurs immediately after the power is turned on for the first time for the day Description There is sometimes a case where the difference of temperature between air and inside of the machine causes moisture to occur on the toner immediately after the power is turned on for the first time for the day. As a result, when the toner transferred on a sheet at the time of initial printing passes through the fixing assembly, moisture on the toner is vaporized into steam, causing breading (smear) to occur. Field Remedy Prevent bleeding using the following user mode items. Setting items
Setting value
Menu> Special Mode b (b)
Not used,Mode 1 through 4 (Factory setting: Mode 1)
Menu> Special Mode c (c)
Not used,Mode 1 through 3 (Factory setting: Not used)
Description Make a setting to perform thinning of printed image data by processing of the controller. When the value set for the mode increases, the amount of thinning increases. (The image density decreases.) Extend the initial rotation period by processing of the engine. When the value set for the mode increases, the initial rotation period is extended.
Additional information Printing time does not increase because the method of image processing performed by the controller is changed. This mode is less effective than Mode c.
The initial rotation period in engine operation is extended, and printing time increases. The initial rotation period for each mode is shown below. Mode 1: 15 sec, Mode 2: 30 sec, Mode 3: 60 sec T-6-1

means to analyze failures occurred in the field. When a request has been made to the HQ of the sales company by the CINC division in charge of field follow-up, collect the log by using the tool.
■■Scope of Application The fax function of the host machine is used as the temporary storage destination of the log. Therefore, the tool cannot be used on a model without the fax function. The tool is supported by Windows XP, Windows Vista and Windows 7. The machine and the PC for operating the tool are connected directly by a USB Cable. Multiple host machines cannot be connected to a PC. Connect only one device to the PC via USB.
F-6-15
4) Preparation of the device Turn OFF the power switch while the machine is in the status (the machine is frozen, misbehaving, etc.) whose log you want to collect. 5) Turn ON the power switch before the data is deleted (within 5 minutes). 6. Collecting the log
●● What to Prepare

■■Operation Procedure
F-6-16
The collected log is created in TXT format in the folder where CanonLogCollector.exe NOTE: The fax function has a data retention mechanism. Backup of data is retained for up to 5 minutes after turning OFF the main power. Collect the log while the data is retained.
1) Connecting the USB Cable Connect the USB Cable while both the machine and the PC are in operation. 2) Decompressing CanonLogCollector.zip
exists. Obtain the created log and send it to the sales company HQ. In the following figure, "usb_2011901_132658.log" is the log file. The size of a log file is 300 KB or less. The time needed to collect the log is approx.10 seconds.
NOTE: While the machine is in operation, log information is continually added. However, the storage area is limited to 300KB, so the information is overwritten in the order from the oldest log information. Since log information may be overwritten when a long time has passed after occurrence of the error, be sure to collect the log as soon as possible.
Create a folder with write permission on the PC. When CanonLogCollector.zip is decompressed, CanonLogCollector.exe is extracted.

Error Code Overview
Details image memory overflow at time of reception has occurred. T-7-4
■■Overview A fax error code shows the status of an error which occurred in a fax, and is displayed on the
Service Error Code
reports. Fax error codes allow users and service technicians to check the status of the error.
■■Error Code
There are two types of fax error codes.
●● Transmission-related Errors
User error codes They show errors which can be easily fixed by users, and are displayed as "# + a 3-digit number". Service error codes They show errors which cannot be fixed by users and need to be fixed by service technicians. They are displayed as "## + a 3-digit number".
CAUTION: Service error codes displayed as "## + a 3-digit number" are not displayed on the communication reports, communication management reports, etc., by default. Service error codes can be displayed by changing bit 0 to "1" in SW01 in service mode (FAX> SSSW).
