Securing the printer 32
Statement of Volatility
Your printer contains various types of memory that can store device and network settings, and user data.
Type of memory Description
Volatile memory Your printer uses standard random access memory
(RAM) to temporarily buer user data during simple print
jobs.
Non-volatile memory Your printer may use two forms of non-volatile memory:
EEPROM and NAND (flash memory). Both types are used
to store the operating system, device settings, network
information and bookmark settings, and embedded
solutions.
Hard disk memory Some printers have a hard disk drive installed. The printer
hard disk is designed for printer-specific functionality.
This lets the printer retain buered user data from
complex print jobs, as well as form data, and font data.
Erase the content of any installed printer memory in the following circumstances:
•The printer is being decommissioned.
•The printer hard disk is being replaced.
•The printer is being moved to a dierent department or location.
•The printer is being serviced by someone from outside your organization.
•The printer is being removed from your premises for service.
•The printer is being sold to another organization.
Disposing of a printer hard disk
Note: Some printer models may not have a printer hard disk installed.
In high‑security environments, it may be necessary to take additional steps to make sure that confidential data
stored in the printer hard disk cannot be accessed when the printer—or its hard disk—is removed from your
premises.
•Degaussing—Flushes the hard disk with a magnetic field that erases stored data
•Crushing—Physically compresses the hard disk to break component parts and render them unreadable
•Milling—Physically shreds the hard disk into small metal bits
Note: Most data can be erased electronically, but the only way to guarantee that all data are completely
erased is to physically destroy each hard disk where data is stored.
Securing the printer 33

transported in the most ecient and environmentally sensitive manner and that there is less packaging to
dispose of. These eciencies result in fewer greenhouse emissions, energy savings, and natural resource
savings. Lexmark also oers recycling of packaging components in some countries or regions. For more
information, go to www.lexmark.com/recycle, and then choose your country or region. Information on available
packaging recycling programs is included with the information on product recycling.
Lexmark cartons are 100% recyclable where corrugated recycling facilities exist. Facilities may not exist in your
area.
The foam used in Lexmark packaging is recyclable where foam recycling facilities exist. Facilities may not exist
in your area.
When you return a cartridge to Lexmark, you can reuse the box that the cartridge came in. Lexmark recycles
the box.
Returning Lexmark cartridges for reuse or recycling
The Lexmark Cartridge Collection Program allows you to return used cartridges for free to Lexmark for reuse
or recycling. One hundred percent of the empty cartridges returned to Lexmark are either reused or
demanufactured for recycling. The boxes used to return the cartridges are also recycled.
To return Lexmark cartridges for reuse or recycling, do the following:
1Go to www.lexmark.com/recycle.
2Select the product that you want to recycle.

FAQ about color printing
What is RGB color?
RGB color is a method of describing colors by indicating the amount of red, green, or blue used to produce
a certain color. Red, green, and blue light can be added in various amounts to produce a large range of colors
observed in nature. Computer screens, scanners, and digital cameras use this method to display colors.
Troubleshooting 102
What is CMYK color?
CMYK color is a method of describing colors by indicating the amount of cyan, magenta, yellow, and black
used to reproduce a particular color. Cyan, magenta, yellow, and black inks or toners can be printed in various
amounts to produce a large range of colors observed in nature. Printing presses, inkjet printers, and color
laser printers create colors in this manner.
How is color specified in a document to be printed?
Software programs are used to specify and modify the document color using RGB or CMYK color
combinations. For more information, see the software program Help topics.
How does the printer know what color to print?
When printing a document, information describing the type and color of each object is sent to the printer and
is passed through color conversion tables. Color is translated into the appropriate amounts of cyan, magenta,
yellow, and black toner used to produce the color you want. The object information determines the application
of color conversion tables. For example, it is possible to apply one type of color conversion table to text while
applying a dierent color conversion table to photographic images.
What is manual color correction?
When manual color correction is enabled, the printer employs user‑selected color conversion tables to
process objects. Manual color correction settings are specific to the type of object being printed (text,
graphics, or images). It is also specific to how the color of the object is specified in the software program
(RGB or CMYK combinations). To apply a dierent color conversion table manually, see “Modifying the colors
in printed output” on page 102.
If the software program does not specify colors with RGB or CMYK combinations, then manual color correction
is not useful. It is also not eective if the software program or the computer operating system controls the
adjustment of colors. In most situations, setting the Color Correction to Auto generates preferred colors for
the documents.
How can I match a particular color (such as a corporate logo)?
From the printer Quality menu, nine types of Color Samples sets are available. These sets are also available
from the Color Samples page of the Embedded Web Server. Selecting any sample set generates
multiple‑page prints consisting of hundreds of colored boxes. Each box contains a CMYK or RGB combination,
depending on the table selected. The observed color of each box is obtained by passing the CMYK or RGB
combination labeled on the box through the selected color conversion table.
By examining Color Samples sets, you can identify the box with color closest to the color being matched.
The color combination labeled on the box can then be used for modifying the color of the object in a software
program. For more information, see the software program Help topics. Manual color correction may be
necessary to use the selected color conversion table for the particular object.
Selecting which Color Samples set to use for a particular color‑matching problem depends on:
•The Color Correction setting being used (Auto, O, or Manual)
•The type of object being printed (text, graphics, or images)
•How the color of the object is specified in the software program (RGB or CMYK combinations)
If the software program does not specify colors with RGB or CMYK combinations, then the Color Samples
pages are not useful. Additionally, some software programs adjust the RGB or CMYK combinations specified
in the program through color management. In these situations, the printed color may not be an exact match
of the Color Samples pages.

Laser notice
The printer is certified in the U.S. to conform to the requirements of DHHS 21 CFR, Chapter I, Subchapter J for
Class I (1) laser products, and elsewhere is certified as a Class I laser product conforming to the requirements
of IEC 60825-1: 2014.
Class I laser products are not considered to be hazardous. The printer contains internally a Class IIIb (3b) AlGaInP
laser that is nominally 15 milliwatts operating in the wavelength region of 650–670 nanometers and enclosed
in a non-serviceable printhead assembly. The laser system and printer are designed so there is never any human
access to laser radiation above a Class I level during normal operation, user maintenance, or prescribed service
conditions.
