Canon will release technical information as the need arises. In the event of major changes xanon the contents of this manual over a long or short period, Canon will issue a new edition of this manual.
Introduction Symbols Used This documentation uses the following symbols to indicate special information: Symbol Description Indicates an item of a non-specific nature, possibly classified as Note, Caution, or Warning.
Indicates an item requiring care to avoid electric shocks. M8f180c an item requiring care to avoid combustion fire. Indicates an item prohibiting disassembly to avoid electric shocks or problems.
Introduction The following rules apply throughout this Service Manual: Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with refer- ence to the timing of operation.
In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbolthe arrow indicates the direction of the electric signal. Xanon 1 Main drive assembly Developing rotary assembly Registration shutter assembly Fixing assembly 1. These ordinances apply to laser products manufactured on and after August 1,and sale of laser products is prohibited within the US unless they bear a certificate of compliance.
Chapter 2 F T  Document feed motor  CCD unit  Flatbed motor Reading from the ADF To avoid skew feeding, documents loaded on the document tray are retained in the horizontal direction by the slide guide.
Then, the documents are fed to the sep- aration roller by the pickup roller, and separated one sheet each using differences in the coefficient of friction among the separation roller, documents, and separation guide. Chapter 2 shading position 1. Chapter 2 8 When the four-sided mirror rotates at a constant speed, the laser beam striking the mahual drum scans on the drum at a constant speed. The circuit diagram of the scanner motor control is illustrated below.
T cleaning ITB cleaning roller roller H. Auxiliary development In this step, CPU applies DC bias onto the toner that was not charged by frictional electrification. Here, the toner becomes uniformed negative potential. The printer charges the uncharged toner by applying DC bias onto the blade inside the toner cartridge.
Secondary transfer The toner on the ITB is transferred onto paper in this step. A DC positive bias is servixe to the secondary transfer roller to charge the back side of a fed paper.
This allows the toner on the ITB to transfer onto paper positively. At the completion of secondary transfer, a DC negative bias is applied to the secondary transfer roller to avoid soiling the back of paper with the toner on the ITB.

Chapter 2 The machine uses an on-demand method, which requires a low thermal capacity. The method enables the machine to start up quickly and servive heater to use little power while the machine is in a standby state.
The machine may therefore be characterized by a short wait time and low energy consumption. The machine applies a positive DC bias to its pressure roller for the purpose of reinforcing the retention of toner on print paper, consequently preventing stray toner.

Chapter 2 In full-color printing, as srevice toner layers in each colors are piled up on the ITB in primary transfer, the holding force of toner weakens as the transfer process progresses for the 1st color, 2nd color Therefore, after transferring the first color, the primary transfer DC positive bias is increased for the toner in the rest of the colors to gain the holding force of the toner.
Then the DCNT Board measures the density of the patterns with the density sensor and controls the developing bias to obtain canoj proper density based on the measured density.
There are four toner cartridges in Y, M, C, and Bk, which are the same in structure. The following indicates the configuration of the cartridges and loads.

Chapter 2 A mechanism used in this control is also used in a developing rotary engaging operation. Developing rotary Drive gear Photosensitive Memory tag drum Memory tag In full-color printing, the detection is performed for the cartridges in each color. In monochrome printing, it is performed just for the Bk cartridge. When the power is turned cnaon or the top cover is closed, the DCNT Board determines the presence or absence of the cartridge by monitoring the following two items: T Drum cartridge Interrupting areas Secondary transfer roller F 2.
Outline The machine uses the following serviec to check the life of the drum cartridge. When the power is turned on, the upper cover is closed, or a print job is over, the DCNT Board checks on the following 2 items, and will assume that the cartridge has reached the end of its life if any of them reaches a specific value: The unit is structured with the secondary transfer roller and engaging lever, which are operated by the main motor drive.
The operations of this control are described in the following: The machine possesses 2 inlet slots for paper i. Fixing delivery paper sensor PS Registration paper sensor PS Multi-purpose tray paper sensor PS Front fixing paper detection sensor DCM The operations of this function are discussed below. Chapter 2 The controls and functions in the fixing control circuit are described next. This printer utilizes three protective functions performed by the following parts, to prevent an abnormal temperature rise of the heater: Fixing mr8180c Power supply unit Then, when the printer enters the standby status, the CPU drives loads such as the laser diodes, motors, solenoids, etc.
The encoder used in this printer consists of a disk, reflective sensor, and detection unit. Be sure to observe the following removing the 2 types of cartridges toner, cabon from he machine.
