Lexmark C54x/X54x Color Product Study Guide Rev 2.6 Theory of Operation X544 and X546dtn MFP Fax System The three basic units of a fax are the scanner (for reading the image), the control circuit, and the printer. • The scanner splits the image into a fine grid, and then reads the brightness (white/black) of each cell. -
Page 23: X543, X544 And X546Dtn Mfp Scanner System
Lexmark C54x/X54x Color Product Study Guide Rev 2.6 X543, X544 and X546dtn MFP Scanner System The document scanning section consists of a scanner that reads a single-sheet document placed on the flatbed glass and an Auto Document Feeder (ADF) that can read the pages of a multiple-sheet and/or duplexed document. - Page 24 Lexmark C54x/X54x Color Product Study Guide Rev 2.6 X543, X544 and X546dtn MFP Document Scanning at the ADF (Auto Document Feeder) When scanning, the MFP will default to the flatbed scanner unless the Paper Present Sensor on the ADF detects the presence of media.

Page 28: Charge
Lexmark C54x/X54x Color Product Study Guide Rev 2.6 Charge During the charge step, voltage is sent from the high-voltage power supply to the charge roller located beside each of the four photoconductors (the charge roller is part of the photoconductor unit). -
Page 29: Expose
Lexmark C54x/X54x Color Product Study Guide Rev 2.6 Expose During the expose step, the laser fires a focused beam of light at the surface of each color Photoconductor and writes an invisible image called a latent image or electrostatic image. This invisible image is created by discharging the Photoconductors only where the laser beam strikes its surface. -
Page 30: Develop
Lexmark C54x/X54x Color Product Study Guide Rev 2.6 Develop Once the laser exposes the Photoconductor, the HVPS sends charge to the Developer Roll. For each color, the Developer Roll engages the Photoconductor so it is in contact with the surface. Because of the charge difference between the toner on the Developer Roller and the electrostatic image on the Photoconductor, toner only attracts to the Photoconductor where the laser exposed the surface. -
Page 31: St Transfer
Lexmark C54x/X54x Color Product Study Guide Rev 2.6 Transfer When the latent images are developed on each Photoconductor, the high-voltage power supply sends voltage to the 1 Transfer Rollers inside the ITU. The charge difference between the developed toner image on the Photoconductor surface and the 1 Transfer Rollers causes the images to transfer to the surface of the ITU belt for each color. -
Page 32: Nd Transfer
Lexmark C54x/X54x Color Product Study Guide Rev 2.6 Transfer Once the four planes of color are transferred to the ITU from the Photoconductors, the image is carried towards the Transfer Roll (this is part of the ITU assembly). The media is picked from the input source and timed to pass between the ITU Belt and Transfer Roll when the image on the Belt reaches the second transfer area. -
Page 33: Fuse
Lexmark C54x/X54x Color Product Study Guide Rev 2.6 Fuse Once the image has been fully transferred to the media, the Transfer Roller helps move the paper into the Fuser area. The Fuser applies heat and pressure to the page to melt the tiny toner particles and bond them permanently to the media. -
Page 34: Clean/Erase
Lexmark C54x/X54x Color Product Study Guide Rev 2.6 Clean/Erase There are two main cleaning processes that take place during the EP Process. One process cleans the ITU Belt and the other cleans the Photoconductors. Transfer Unit Clean Once the image on the ITU Belt is transferred to the media, the Cleaning Blade scrapes any residual toner left on the surface of the Belt. -

Light Non-uniform Print / “Mottled” appearance Problem Description: Poor toner transfer in humid environments will cause the printed page to look faded, have a mottled appearance, seem light, washed out or non-uniform in print (see picture below). -
Page 63: "Milky" Appearance On Paper
Lexmark C54x/X54x Color Product Study Guide Rev 2.6 “Milky” Appearance on Paper Problem Description: The defects are created when the toner melts and moves prior to pressure in the fuser. This movement exposes the media color under the toner and creates a light, “milky” appearance on the media (see picture below). -
