USBA host ports for flash drives on the operator panel, and an optional 650-sheet Duo Drawer with 550 sheets in the input tray and 100 sheets for the multipurpose feeder. The Lexmark 5027‑630 has a standard 650-sheet Duo Drawer and the option to add a 550-sheet tray, which brings the input for that model up to 1,451 sheets.
Page 24: Paper Guidelines
Paper characteristics Selecting the appropriate media for the printer can help avoid printing problems. For detailed information about media characteristics, see the Card Stock & Label Guide available on the Lexmark Support Web site at http://support.lexmark.com. The following paper characteristics affect print quality and reliability. Consider these characteristics when evaluating new paper stock.
Page 25: Unacceptable Paper

Page 26: Supported Paper Sizes, Types, And Weights
5027 Storing paper Use these paper storage guidelines to help avoid jams and uneven print quality: • For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40 percent. Most label manufacturers recommend printing in a temperature range of 18–24°C (65–75°F) with relative humidity between 40 and 60 percent.

Page 29: 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.

5027 supplier. Remember that these are general guidelines only and that paper meeting these guidelines may still cause paper feeding problems in any laser printer (for example, if the paper curls excessively under normal printing conditions). Data security notice The printer contains various types of memory that store device and network settings, information from embedded solutions, and user data.

Page 339: Appendix B: Options And Features
“Option configurations” on page 340 Lexmark CS310, CS410, and CS510 support only Lexmark CS310, CS410, and CS510 paper-handling options. These options are not compatible with any other Lexmark printer. Some of the following options are not available in every country or region.
Page 340: Option Configurations
C544dn printers, the CS310, CS410, and CS510 printers support a maximum of two stacked optional drawers–one 650 DuoDrawer at tray 2, and an additional 550 drawer at tray 3. The CS310, CS410, and CS510 DuoDrawers are also designed to be downward compatible with the C544n and C544dn printers. Because the C544n and C544dn 650 DuoDrawer, and the CS310, CS410, and CS510 650 DuoDrawer and 550 drawer share the same autoconnect features, there are several ways in which the drawers can be stacked together.

Page 343: Appendix C: Theory Of Operation
5027 Appendix C: Theory of operation • “Paper path and transport components” on page 343 • “Print engine theory” on page 346 • “Color theory” on page 350 Paper path and transport components For an image to be printed, the paper or specialty media has to be moved from an input source (such as a tray) into the printer and eventually exit into an output source.
Page 344: Transport Components
5027 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 345: Duplexing
5027 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 346: Print Engine Theory
5027 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) The method that all laser and LED printers use to print is called the electrophotographic process. These machines use differences in charge to manipulate and move toner from the print cartridge to the printed page.
Page 347 5027 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 348 5027 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 349 5027 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.
Page 350: Color Theory
5027 Color theory 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. Televisions and computer monitors create colors in this manner.
Page 351: What Is Manual Color Correction
5027 My color transparencies seem dark when they are projected. Is there anything I can do to improve the color? This problem most commonly occurs when projecting transparencies with reflective overhead projectors. To obtain the highest projected color quality, transmissive overhead projectors are recommended. If a reflective projector must be used, then adjusting the Toner Darkness setting to 1, 2, or 3 will lighten the transparency.

CMYK Text • Euro CMYK—Applies color correction to approximate EuroScale color output. CMYK Graphics • Vivid CMYK—Increases the color saturation of the US CMYK color correction setting. •...
Page 353 5027 When the Detailed Options page appears, select a color conversion table. Enter the RGB or CMYK color number. Enter an Increment value from 1–255. Note: The closer the value is to 1, the narrower the color sample range will appear. Click Print to print the detailed Color Samples set.
