Page 11: Using Your Documentation
250-sheet paper tray. Using your documentation Your Lexmark C720 online information provides details about color functions, media specifications, memory requirements, the operator panel, printer configuration, printer settings, troubleshooting problems, and ordering supplies.
Page 12: Chapter 2: Using Printer Drivers
Using printer drivers Using the printer drivers supplied with your printer gives you the greatest control over the features and functions of your printer. These printer drivers are designed to work efficiently with your printer and provide you with the best possible print quality. Using and accessing these drivers from your computer is fast, easy, and convenient.
Page 13: Chapter 3: Changing Printer Settings
Changing printer settings You can change your printer setting by using your application software, your Lexmark printer driver, the printer operator panel, or the remote operator panel available from MarkVision. Note: Printer settings selected from a software application or driver override default settings selected from the operator panel.
Page 14: Understanding The Operator Panel
Understanding the operator panel The operator panel on the top left side of your printer has a 2-line by 16-character liquid crystal display (LCD), five buttons, and one indicator light. The operator panel can be disabled so that other users cannot access most of the menus.
Page 15: Changing Menu Settings
Operator panel buttons Button Function Press Select Select • Select the menu shown on the second line of the display and view the available menu items. • Select the menu item shown on the second line of the display and view the available value or current user default setting for that menu item.

Page 17 some distance from your computer, it may be more convenient to use the remote operator panel on your computer. In addition to the remote operator panel, some versions of MarkVision also provide a way to view many of the menu items for one menu on a single screen. If you need to make several changes to settings in the Paper Menu, for example, you may find it easier to make those changes when you can see all of the menu items and their available values at one time.
Page 18: Chapter 4: Using Print And Hold
Using Print and Hold When sending a job to the printer, you can specify in the driver that you want the printer to hold the job in memory and not print it immediately. When you are ready to print the job, you must go to the printer and use the operator panel menus to identify which held job you want to print.
Page 19: Accessing Held Jobs From The Operator Panel
Accessing held jobs from the operator panel To access held jobs from the operator panel: – If the printer is Busy, press to display the Job Menu. Menu> – If the printer is Ready, continue with step 2. Press until either HELD JOBS or CONFIDENTIAL JOB shows on the operator Menu>...
Page 20: Repeat Print
Repeat Print If you send a Repeat Print job, the printer prints all requested copies of the job and stores the job in memory so you can print additional copies later. You can print additional copies as long as the job remains stored in memory.
Page 21: Enter Pin
When you select Confidential Job from the Job Menu, the following prompt appears: Enter PIN: =______ Return Select Menu Stop Enter the PIN you assigned and press to print the confidential job.
Page 22: Chapter 5: Understanding Color
Understanding color Your printer gives you the power to communicate in color. Color attracts attention, commands respect, and adds value to your printed material or information. Using color increases readership and is read more often than the same material printed in black and white. Color can be used to motivate people and speed the analysis of complex data.
Page 23: Primary Colors
Primary colors Notice the three primary additive colors red, green, and blue in the illustration. You can see that when all three colors are combined, you get white. However, look at the area where any two colors overlap. What you see is cyan, magenta, or yellow. Equal amounts of green and blue produce cyan. Equal amounts of blue and red produce magenta, and equal amounts of red and green produce yellow.
Page 24: Color Difference
Color difference Most software applications today provide us with a WYSIWYG (What You See Is What You Get) environment. This helps us develop the look of our document. However, the difference between the additive and subtractive colors may sometimes cause a problem between what you see and what you get.
Page 25 document. Always print a new swatch of the colors you plan on using before you invest a lot of time creating your screen designs.
Page 26: Chapter 6: Managing Color
Managing color There are many color management systems on the market today. They range from simple swatchbooks to specially designed and designated color servers. A color management system (CMS) helps you match colors across a number of devices, including scanners, monitors, and printers. A CMS ensures what you see at every step of the publishing process matches the printed output.
Page 27: Popular Color Management Systems
Popular color management systems There are many color management systems for you to choose from. The type of CMS you choose impacts the color quality of your printed output. Choose a CMS that best meets your cost and performance needs. Some popular color management systems are described here. Windows ICM Microsoft Windows 95/98/Me, Windows 2000, and Windows NT support Image Color Management (ICM).
Page 28: Chapter 7: Controlling Printed Output
Controlling printed output Your printer driver provides you with the best quality output for various types of printing needs. However, you may want more control over how your printed document will look. You can control the screening methods, graphics effects, and fill resolution used during printing. These setting adjustments can easily be made through your printer driver, operator panel, or MarkVision remote operator panel.
Page 29: Photo Enhance
You can change these settings through the color tab on your printer driver or the Color Menu on the operator panel. Photo Enhance When you place Photo Enhance setting On, your printer changes the method it uses to place pels on your print media.
Page 30: Halftone Screens
Halftone screens The term halftone screen refers to the pattern of dots applied to an object on the page (text, graphics, or images). If you look at a black and white photograph in a magazine, it appears to contain many shades of gray.
Page 31: Image Smoothing
Spot function The spot function determines the shape of the dots by controlling the order in which the pels in the halftone cell are turned on. The printer code defines the order by assigning a priority to each individual pel within the halftone cell. By turning on or printing a portion of the pels within the halftone cell and then combining the different halftone screens, your printer is able to print millions of colors.
Page 32: Chapter 8: Color Correction
Color correction Color Correction lets you modify the color settings used to print your documents. The Color Correction settings you can choose from are: Auto, Display, CMYK, Black and White, 2-Color draft, Off, and Vivid. Auto is the default setting when the printer is shipped from the factory. It uses different color profiles for the different objects on the page (text, graphics, and images).
Page 33: Black And White
If you use this setting without the necessary color management software or your application does not provide the correct information, your printed output may have unexpected results. Black and White The Black and White setting converts any colors in your document to solid black. This setting produces output just like any standard monochrome printer using various shades of gray.
Page 34: Chapter 9: Avoiding Print Quality Problems
Transparencies To ensure high quality output on transparencies, we recommend using the following Lexmark transparencies. They have been designed specifically for your printer: P/N 12A5590 (letter size) P/N 12A5591 (A4 size) These transparencies have characteristics that minimize curl and optimize toner transfer in a wide range of printing environments.
Page 35: Chapter 10: Paper Sources And Output
Paper sources and output Your printer comes with a 250-sheet paper tray. You can load paper, transparencies, labels, or envelopes in the paper tray. For additional paper capacity, you can attach an optional drawer with a 500-sheet tray. When linked, you create a single 750-sheet source (see Tray linking).
