Page 23: General Information
7527 General information The Lexmark CX310, CX410, and CX510 (7527‑2xx, 7527‑4xx, 7527‑6xx) are network‑capable, multi‑function laser printers that print both four‑color and monochrome print jobs. All information in this service manual pertains to all models unless explicitly noted. The printers are available in the following models:...
Page 24: Moisture Content
7527 Weight The printer trays can automatically feed paper weights up to 176‑g/m (47‑lb) bond grain long paper. The multipurpose feeder can automatically feed paper weights up to 176‑g/m (47‑lb) bond grain long paper. Paper lighter than 60 g/m (16 lb) might not be stiff enough to feed properly, causing jams. For best performance, use 75‑g/m (20‑lb) bond grain long paper.
Page 25: Selecting Paper
7527 • Preprinted papers that require a registration (the precise print location on the page) greater than ±2.3 mm (±0.9 in.), such as optical character recognition (OCR) forms In some cases, registration can be adjusted with a software application to successfully print on these forms. •...
Page 26: Using Recycled Paper And Other Office Papers
Lexmark consistently tests its printers with recycled paper (20–100% post-consumer waste) and a variety of test paper from around the world, using chamber tests for different temperature and humidity conditions. Lexmark has found no reason to discourage the use of today's recycled office papers, but generally the following property guidelines apply to recycled paper.

7527 • Hard disk memory—Some devices have a hard disk drive installed. The printer hard disk is designed for device- specific functionality and cannot be used for long term storage for data that is not print-related. The hard disk does not provide the capability for users to extract information, create folders, create disk or network file shares, or transfer FTP information directly from a client device.

C544dn printers, the CX310, CX410, and CX510 printers support a maximum of two stacked optional drawers— one 650 DuoDrawer at tray 2, and an additional 550 drawer at tray 3. The CX310, CX410, and CX510 DuoDrawers are also designed to be downward compatible with the C544n and C544dn printers. Because the C544n and C544dn 650 DuoDrawer, and the CX310, CX410, and CX510 650 DuoDrawer and 550 drawer share the same autoconnect features, there are several ways in which the drawers can be stacked together.

Page 392: Transport Components
7527 There is a duplex unit on the printers. The duplex unit is built into the front cover and Tray 1. Note: The ACM is also known as the paper feed roller assembly. Transport components The paper is fed from the tray into the printer by a pick roll and sent to two sets of feed rollers which time the paper to enter the Electrophotographic Process (EP Process) at just the right moment.
Page 393: Duplexing
7527 The redrive bubble sensor, located before the fuser exit rollers in the paper path, senses the bubble in the paper as it exits the fuser. It then adjusts the fuser motor speed as necessary to avoid jams and smearing on the trailing edge of the paper.
Page 394: Print Engine Theory
7527 Once the image is transferred, the media travels to the fuser (D), the fuser exit rolls (E), and then to the output bin. Print engine theory • “Electrophotographic process (EP process)” on page 394 • “Electrophotographic process basics” on page 394 Electrophotographic process (EP process) The method that all laser and LED printers use to print is called the electrophotographic process.
Page 395 7527 During the printing process, the printer follows the six basic EP Process steps to create its output to the page. Charge the photoconductor. Expose the photoconductor with the laser. Develop toner on the photoconductor. First transfer to the ITU, and second transfer to the paper. Fuse the toner to the paper.
Page 396 7527 Service tips • The laser beam passes through a glass lens as it exits the laser unit. If this lens gets contaminated with toner or other debris, it will cause vertical streaking of white/lightness on the page. Cleaning the lens will solve the problem. •...
Page 397 7527 The HVPS sends voltage to the transfer roll to create a positive charge. When the image on the transfer belt reaches the transfer roll, the negatively charged toner clings to the paper and the entire image is transferred from the transfer belt to the paper.

The scanner control unit, on the controller board receives a command to create a scan, fax, or copy. The scanner control unit, on the controller board receives a command to create a scan, fax, or copy. A signal is sent to the ADF to poll the document sensor (1) to check if the media to be scanned is in the correct position.

7527 Color theory • “Color theory” on page 400 Color theory What is RGB color? Red, green, and blue light can be added together in various amounts to produce a large range of colors observed in nature. For example, red and green can be combined to create yellow.
