Data Security Notice

I d e n t i fy i n g P r i n t e r M e m o r y
• Volatile memory—The printer uses standard random access memory (RAM) to buffer user data
temporarily during simple print and copy jobs.
• Nonvolatile memory—The printer may use two forms of nonvolatile memory: EEPROM and
NAND (flash memory). Both types are used to store the operating system, printer settings,
network information, scanner and bookmark settings, and embedded solutions.
• Hard disk memory—Some printers have a hard disk drive installed. The hard disk is designed for
printer-specific functionality and cannot be used for long-term storage of data that is not print-
related. The hard disk does not let users extract information, create folders, create disk or network
file shares, or transfer FTP information directly from a client device. The hard disk can retain
buffered user data from complex print jobs, form data, and font data.
The following parts can store memory:
• Printer control panel
• User interface controller card (UICC)
• Optional hard disks
Note: The printer control panel and controller board contain NVRAM.
E ra s i n g Pr i n t e r M e m o r y
To erase volatile memory or buffered data, turn off the printer.
To erase non-volatile memory or individual settings, device and network settings, security settings,
and embedded solutions, do the following:
1. From the control panel, navigate to:
Settings > Device > Maintenance > Out of Service Erase > Sanitize all information on
nonvolatile memory > Yes
2. Select either Start initial setup or Leave printer offline.

H a n d l i n g E S D - s e n s i t i v e Pa r t s
Many electronic products use parts that are known to be sensitive to electrostatic discharge (ESD). To
prevent damage to ESD-sensitive parts, do the following:
• Turn off the printer before removing logic boards.
• Keep the parts in their original packing material until you are ready to install them into the
printer.
• Make the least possible movements with your body to prevent an increase of static electricity
from clothing fibers, carpets, and furniture.
• Put the ESD wrist strap on your wrist. Connect the wrist band to the system ground point. This
action discharges any static electricity in your body to the printer.
• Hold the parts by their edge connector shroud. Do not touch its pins. If you are removing a
pluggable module, then use the correct tool.
• If possible, keep all parts in a grounded metal cabinet.
• Do not place the parts on the printer cover or on a metal table. If you need to put down the parts,
then put them into their packing material.
• Prevent parts from being accidentally touched by other personnel. Cover the printer when you are
not working on it.
• Be careful while working with the parts when cold-weather heating is used. Low humidity
increases static electricity.

Keep the following tips in mind as you replace parts:
• Some removal procedures require removing cable ties. You must replace cable ties during
reassembly to avoid pinching wires, obstructing the paper path, or restricting mechanical
movement.
• Remove the toner cartridges, imaging unit, and trays before removing other printer parts. The
imaging kit must be carefully set on a clean, smooth, and flat surface. It must also be protected
from light while out of the printer.
• Disconnect all external cables from the printer to prevent possible damage during service.
• Unless otherwise stated, install the parts in reverse order of removal.
• When installing a part held with several screws, start all screws before the final tightening.
• For printers that have an electronic power switch, make sure to unplug the power cord after
powering off.

job.
Sleep Mode The product is in a high-level 0.8 (B305); 1.1 (B315)

energy-saving mode.
Hibernate The product is in a low-level 0.1

energy-saving mode.
Off The product is plugged into an 0.1

electrical outlet, but the power
switch is turned off.
The power consumption levels listed in the previous table represent time-averaged measurements.
Instantaneous power draws may be substantially higher than the average.
Values are subject to change. See www.xerox.com for current values.
Sleep Mode
This product is designed with an energy-saving mode called Sleep Mode. The Sleep Mode saves
energy by lowering power consumption during extended periods of inactivity. The Sleep Mode is
automatically engaged after this product is not used for a specified period of time, called the Sleep
Mode Timeout.
Factory default Sleep Mode Timeout for this product 15
(in minutes):
By using the configuration menus, the Sleep Mode Timeout can be modified between 1 minute and
120 minutes. If the print speed is less than or equal to 30 pages per minute, then you can set the
timeout only up to 60 minutes. Setting the Sleep Mode Timeout to a low value reduces energy
consumption, but may increase the response time of the product. Setting the Sleep Mode Timeout to
a high value maintains a fast response, but uses more energy.

Service Manual
Hibernate Mode
This product is designed with an ultra-low power operating mode called Hibernate mode. When
operating in Hibernate Mode, all other systems and devices are powered down safely.
The Hibernate mode can be entered in any of the following methods:
• Using the Hibernate Timeout
• Using the Schedule Power modes
Factory default Hibernate Timeout for this product in 3 days

all countries or regions
The amount of time the printer waits after a job is printed before it enters Hibernate mode can be
modified between one hour and one month.
Off Mode
If this product has an off mode which still consumes a small amount of power, then to completely
stop product power consumption, disconnect the power supply cord from the electrical outlet.
To t a l E n e r g y U s a g e
It is sometimes helpful to estimate the total product energy usage. Since power consumption claims
are provided in power units of Watts, the power consumption should be multiplied by the time the
product spends in each mode in order to calculate energy usage. The total product energy usage is
the sum of each mode's energy usage.

Theory Of Operation
Charge
1 Charge roller
2 Photoconductor
The charge roller applies a uniform negative electrical charge to the surface of the photoconductor.
The insulative properties of the photoconductor allow it to hold a charge and its photoconductive
properties allow it to discharge when exposed to light.

Service Manual
Theory Of Operation
Expose
1 Photoconductor
2 Printhead
The printhead emits a laser that exposes the surface of the photoconductor. The laser pulses coincide
with the digital latent image. The exposed areas of the photoconductor surface are discharged,
resulting in a photoconductor surface potential that is less negative than the non-exposed areas.

Service Manual
Theory Of Operation
D eve l o p
1 Developer roller
2 Toner cartridge
3 Photoconductor
The developer roller applies the toner from the toner cartridge to the photoconductor during the
development process. The difference in surface potential creates an electric field that causes the
toner particles to move to the photoconductor according to the pattern of the latent image.

Service Manual
Theory Of Operation
Tra n s fe r
1 Charge roller
2 Transfer roller
3 Paper
A positive potential relative to the toned image formed on the photoconductor is applied to the
transfer roller. This allows the transfer roller to move the developed toner from the surface of the
photoconductor to the paper as the paper is passed between the transfer roller and photoconductor.
Clean
The cleaning blade removes the residual toner from the photoconductor after the transfer. After
cleaning, the process moves again to the charge process and repeats each cycle until the entire
image is transferred to a side of the paper.

Service Manual
Theory Of Operation
Fu s e
1 Fuser
2 Paper
After the toner image is transferred to the paper, the toner particles are not yet permanently bonded
to the paper. For the final step in the print process, paper is transported to the fuser where heat and
pressure are applied to it. As a result, the toner particles melt and are permanently fused to the paper,
completing the print process. The print cycle repeats for the succeeding pages.

The pick roller picks and the feed roller feeds the paper to the separator roller or separator pad. The
feed roller feeds the paper to the transport roller. For MPF print jobs, the MPF pick roller picks and
feeds the paper to the transport roller.
The transport rollers feed the paper to the transfer roller. At the transfer roller, the photoconductor
transfers the developed image to the paper to create the printed image.
As the paper passes the fuser, heat and pressure are applied to permanently bond the toner to the
paper.
After printing, the paper exit roller ejects the paper to the output bin.
D u p l e x Pr i n t J o b
1 Duplex rear roller
2 Duplex front roller
After the first side is printed, the paper stops at the output bin while still in the paper exit roller. The
paper is fed again into the duplex paper path to have the opposite side printed.
The paper travels along the duplex path until it enters again the transport roller. From there, the
paper continues its path until the print job is done.

5 Standard tray
The motor (main drive) in the printer drives the standard tray. The lift plate in the tray is spring
loaded and is not driven by a motor. The spring raises the lift plate until the paper is in contact with
the pick roller.
The motor inside the optional tray drives the optional tray. The motor drives the lift plate to a
specified height in the tray.
To prepare for feeding, the lift plate raises to push the paper against the pick roller. The lift plate
stops pushing at the point where the pick roller is at the proper height for picking. After the pick roller
is in position, it feeds the topmost paper. The separator roller and separator pad ensures that only
one sheet is fed at a time.

Paper from the ADF tray enters the ADF through the ADF pick roller, ADF feed roller, and ADF
separator pad. On the ADF tray, the sensor (ADF paper present) detects if paper is loaded.
After the paper is fed, it travels to the ADF scan roller for scanning. As the paper passes the sensor
(ADF scan), the scanner under the ADF obtains the image from the sheet. If equipped, a CIS unit
obtains the image from the other side of the sheet in a duplex scan job.
After the paper is scanned, the ADF exit roller ejects the paper to the ADF bin.
