Printer overview
The following illustrations show a Lexmark™ C910 standard model configuration and a fully configured
network printer. If you have attached paper handling options to your printer, it may look more like the
fully configured model. For information on other possible configurations, refer to the Setup Guide.
Standard model configuration
Fully configured
The Lexmark C910 is a network color printer that uses electrophotographic technology to deliver high
quality images, presentation graphics, line art, and text. Its fast output, up to 28 pages per minute
(ppm) for both four-color and monochrome print jobs-makes it the ideal solution for businesses where
performance is critical.
The printer's flexible design allows it to support a variety of printing needs. For example, if you print a
mixture of color and mono (black only) jobs, you can choose to maximize print speed or maximize
supplies yield. If you need the printer to match the color process used in a particular application, you
can select RGB or CMYK color corrections. You can also adjust the printed colors to more closely
represent the colors on your computer display.
A variety of connectivity options make the printer an excellent choice for all types of system
environments. You can attach up to two internal adapters to support network configurations requiring
Ethernet, Token-Ring, LocalTalk, serial, infrared, or additional parallel ports. You can even attach a
class 1 fax modem to the optional serial port and receive faxes directly to your printer.
9
The printer also offers flexible paper handling. It supports a wide variety of paper sizes, from A5 to A3
and 11x17 in., and has a standard multipurpose feeder that makes it easy to print on envelopes,
transparencies, labels, card stock, and non-standard size paper. You can add up to three optional
drawers to the base printer, which can increase the printer's paper capacity to 2300 sheets. You can
also add an optional high capacity feeder making the total paper capacity 5300 sheets.
Print speed
Your printer can print four-color and mono jobs at up to 28 ppm. With all printers, print speed varies
depending on specific characteristics of the job, such as the size of the formatted page, the number of
fonts, the number and complexity of images and graphics, and so on. Printing a mix of color and mono
jobs may also slow printing, depending on the printer settings you have chosen.
Memory
Your printer ships with 64MB of memory for fast, efficient processing of color jobs. (Some models may
ship with more memory.)
You can install an optional hard disk for storing downloaded resources and job statistics, and for
spooling or collating print jobs. Resources stored in flash memory or on disk are retained in memory
even after the printer is turned off and back on.
Paper handling
The printer comes equipped with a 550-sheet paper tray and a multipurpose feeder. (Some models
may ship with a second 550-sheet tray.) The multipurpose feeder lets you load a stack of envelopes,
transparencies, labels, or card stock for multiple-page jobs. To increase paper feeding capacity, you
can attach up to three optional drawers, each with a 550-sheet tray, and one optional 3000-sheet high
capacity feeder.

Avoiding print quality problems
To prevent print quality problems, do not touch the roller on the bottom of the toner cartridge, the shiny
green tube on the photodeveloper, the film on the transfer belt, or the fuser rollers. Scratches or
fingerprints on any of these surfaces can affect print quality.
Media and supplies
Always use media that meets the recommended guidelines. Refer to the Card Stock & Label Guide for
more information.
Feeding media that is too heavy, too light, damp, damaged, or otherwise unacceptable for this printer
may result in damage to the printer, paper jams, or print quality problems.
Some print quality problems may indicate it is time to replace certain printer supplies. Check the
operator panel display, the Supplies Menu, or MarkVision for an indication of any supply items that may
need to be replaced.
Depending on the type of jobs you print and the media you use, some parts or supplies may wear or
become expended faster than anticipated. See Maintenance for more information about supplies and
when to replace them.
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 12A5940 (letter size)
P/N 12A5941 (A4 size)
These transparencies have characteristics that minimize curl and optimize toner transfer in a wide
range of printing environments. If you use other transparencies, the print quality may be unacceptable
or if you use transparencies not intended for laser printers, you could cause damage to the printer.
Handle transparencies carefully because fingerprints may affect the adhesion of toner. Always set the
Paper Type to Transparency before printing transparencies. This adjusts the fuser temperature and
slows the print speed to ensure the best possible transfer of toner.
See Loading paper and transparencies for more information.

Canceling a print job
To cancel a print job:
1 Press Menu.
Job Menu appears on the first line of the display and Cancel Job appears on the second line.
2 Press Select.
Canceling Job briefly appears on the display. The printer finishes printing any page already
being printed, and then stops. The printer returns to the Ready state.

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.
Your printer default is set to give you the best screen frequency setting for high quality business
graphics. You can however control the image smoothing, color correction, print mode, and toner
darkness settings used during printing. Adjusting any of these settings affects the output of your
documents. These setting adjustments can easily be made through your printer driver, operator panel,
or MarkVision remote operator panel. Refer to the drivers CD for information on MarkVision.
Different printing needs do require different screen frequency settings; for example, offset printing
requires a higher setting, whereas newsprint generally requires a lower setting. Your printer default is
set to give you the best screen frequency setting for high quality business graphics.
Image Smoothing
You can turn Image Smoothing on from the graphics tab of your printer driver or from the operator
panel. This increases the contrast and sharpness of bitmapped images and smooths color transitions.
This setting is useful for images downloaded from the World Wide Web at 72 dpi. The setting has no
effect on images downloaded at 300 dpi resolution or higher.
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, Off, Vivid, and Manual. 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).
For more information refer to the Color correction section of the Color Menu.
Print mode
You can select between color or black and white printing. 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. This setting can be especially useful when you have
replaced a monochrome printer and want to print occasional color. Cost conscious users benefit most
by using this setting as a default and print color only when needed.
13
Toner darkness
This setting lets you adjust the amount of toner released during printing. Your printer offers five Toner
Darkness settings. The values range from 1 (lightest setting) to 5 (darkest setting). The default toner
darkness setting is 4.
Printing text
In both PostScript and PCL emulations, 100% black text prints using black toner (K of CMYK). This
results in sharp, crisp text characters. The printer applies a unique screening algorithm to small text
(less than 24 points in size). This helps ensure that small point size text has smooth, crisp edges.
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. If you place the same picture under a magnifying glass, you see that it is actually
composed of a large number of small dots. These dots, also known as pels, may be of varying sizes or
varying tones. Without halftoning, it would not be possible to produce quality photographic images on a
page printer. This process of representing an image as a series of halftones is known as halftone
screening.
Attributes
Halftone screens have three main attributes: screen frequency, screen angle, and spot function. The
halftone screen is further divided into halftone cells. These cells contain the individual pel spaces. The
screen frequency and angle attributes determine both the number of halftone cells that make up a
halftone screen and the orientation of the cell.
The spot function determines which of the individual pels in the halftone cell is turned on to represent a
particular gray level or color tone. The following illustration shows a halftone screen and halftone cells
rotated 45 degrees.
Frequency (cells
per inch)
Spot function
Angle
14
Screen frequency
The screen frequency is the number of halftone cells per inch. A higher screen frequency setting
increases the number of halftone cells per inch. Increasing the number of halftone cells per inch does
not necessarily give you better quality. The reason for this is the higher settings may make the colors or
halftones seem to run together or bleed.
Different printing needs do require different screen frequency settings; for example, offset printing
requires a higher setting, whereas newsprint generally requires a lower setting. Your printer default is
set to give you the best screen frequency setting for high quality business graphics.
Screen angle
The default angle of the halftone screen and cells place the dots so they are the least noticeable to the
eye. It also ensures the alignment of color through all four color planes. By avoiding the placement of
halftone cells at an angle of 90 degrees, the viewer’s eyes are focused on the image and not on the
dots.
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.

Using the operator panel
This section contains information about understanding the operator panel, changing printer settings,
and understanding operator panel menus.
You can change most printer settings from your software application or printer driver. Settings you
change from the application or printer driver apply only to the job you are preparing to send to the
printer.
Changes made to printer settings from a software application override changes made from the
operator panel.
If you cannot change a setting from your application, use the operator panel or the remote operator
panel available from MarkVision. Changing a printer setting from the operator panel or from
MarkVision makes that setting the user default. Refer to the drivers CD for information about
MarkVision.
Understanding the operator panel
The printer operator panel has a 2-line by 16-character liquid crystal display (LCD), five buttons, and
one indicator light.
