5. Troubleshooting
Toner specks • The paper may not meet specifications; for example, the paper may be too moist or rough.
• The transfer roller may be dirty. Clean the inside of your machine (see "Cleaning the machine" on page 11).
• The paper path may need cleaning. Contact a service representative (see "Cleaning the machine" on page 11).
Dropouts If faded areas, generally rounded, occur randomly on the page:
• A single sheet of paper may be defective. Try reprinting the job.
• The moisture content of the paper is uneven or the paper has moist spots on its surface. Try a different brand of paper.
• The paper lot is bad. The manufacturing processes can cause some areas to reject toner. Try a different kind or brand of paper.
• Change the printer option and try again. Go to Printing Preferences, click the Paper tab, and set type to Thick or Thicker (see
"Opening printing preferences" on page 13).
If these steps do not correct the problem, contact a service representative.
White Spots If white spots appear on the page:
• The paper is too rough and a lot of dirt from paper falls to the inner components within the machine, so the transfer roller may be
dirty. Clean the inside of your machine (see "Cleaning the machine" on page 11).
• The paper path may need cleaning. Clean the inside of your machine (see "Cleaning the machine" on page 11).
If these steps do not correct the problem, contact a service representative.

5. Troubleshooting
Vertical lines If black vertical streaks appear on the page:
• The surface (drum part) of the toner cartridge inside the machine has probably been scratched. Remove the toner cartridge and
install a new one (see "Replacing the toner cartridge" on page 8).
If white vertical streaks appear on the page:
• The surface of the LSU part inside the machine may be dirty. Clean the inside of your machine (see "Cleaning the machine" on page
11). If these steps do not correct the problem, contact a service representative.
Black background If the amount of background shading becomes unacceptable:
• Change to a lighter weight paper.
• Check the environmental conditions: very dry conditions or a high level of humidity (higher than 80% RH) can increase the amount
of background shading.
• Remove the old toner cartridge and install a new one (see "Replacing the toner cartridge" on page 8).
• Thoroughly redistribute the toner (see "Redistributing toner" on page 7).
Toner smear • Clean the inside of the machine (see "Replacing the toner cartridge" on page 8).
• Check the paper type and quality.
• Remove the toner cartridge and install a new one (see "Replacing the toner cartridge" on page 8).

5. Troubleshooting
Vertical repetitive defects If marks repeatedly appear on the printed side of the page at even intervals:
• The toner cartridge may be damaged. If you still have the same problem, remove the toner cartridge and, install a new one (see
"Replacing the toner cartridge" on page 8).
• Parts of the machine may have toner on them. If the defects occur on the back of the page, the problem will likely correct itself after
a few more pages.
• The fusing assembly may be damaged. Contact a service representative.
Background scatter Background scatter results from bits of toner randomly distributed on the printed page.
• The paper may be too damp. Try printing with a different batch of paper. Do not open packages of paper until necessary so that
the paper does not absorb too much moisture.
• If background scatter occurs on an envelope, change the printing layout to avoid printing over areas that have overlapping seams
on the reverse side. Printing on seams can cause problems.
Or select Thick Envelope from the Printing Preferences window (see "Opening printing preferences" on page 13).
• If background scatter covers the entire surface area of a printed page, adjust the print resolution through your software application
or in Printing Preferences (see "Opening printing preferences" on page 13). Ensure the correct paper type is selected. For example:
If Thicker Paper is selected, but Plain Paper actually used, an overcharging can occur causing this copy quality problem.
• If you are using a new toner cartridge, redistribute the toner first (see "Redistributing toner" on page 7).
Toner particles are around bold
characters or pictures
The toner might not adhere properly to this type of paper.
• Change the printer option and try again. Go to Printing Preferences, click the Paper tab, and set the paper type to Recycled (see
"Opening printing preferences" on page 13).
• Ensure the correct paper type is selected. For example: If Thicker Paper is selected, but Plain Paper actually used, an overcharging
can occur causing this copy quality problem.

• Remove the toner cartridge and then, install a new one (see "Replacing the toner cartridge" on page 8).
If the problem persists, the machine may require repair. Contact a service representative.
Character voids Character voids are white areas within parts of characters that should be solid black:
• You may be printing on the wrong surface of the paper. Remove the paper and turn it around.
• The paper may not meet paper specifications.
Horizontal stripes If horizontally aligned black streaks or smears appear:
• The toner cartridge may be installed improperly. Remove the cartridge and reinsert it.
• The toner cartridge may be defective. Remove the toner cartridge and install a new one (see "Replacing the toner cartridge" on
page 8).

Common Linux problems
Refer to the Linux User’s Guide that came with your computer for further information on Linux error messages.
Condition Suggested solutions
The machine does not print. • Check if the printer driver is installed in your system. Open Unified Driver Configurator and switch to the Printers tab in the
Printers configuration window to look at the list of available machines. Make sure that your machine is displayed on the list. If
not, open Add new printer wizard to set up your device.
• Check if the machine is started. Open Printers configuration and select your machine from the printers list. Look at the
description in the Selected printer pane. If its status contains Stopped, press the Start button. Normal operation of the machine
should be restored. The “stopped” status might be activated when some problems in printing occur.
• Check if your application has special print options such as “-oraw”. If “-oraw” is specified in the command line parameter, then
remove it to print properly. For Gimp front-end, select “print” -> “Setup printer” and edit the command line parameter in the
command item.
The machine does not print
whole pages, and output is
printed on half the page.
It is a known problem that occurs when a color machine is used on version 8.51 or earlier of Ghostscript, 64-bit Linux OS, and has been
reported to bugs.ghostscript.com as Ghostscript Bug 688252.The problem is solved in AFPL Ghostscript v. 8.52 or above. Download
the latest version of AFPL Ghostscript from http://sourceforge.net/projects/ghostscript/ and install it to solve this problem.
“Cannot open port device file”
error message appears when
printing a document.
Avoid changing print job parameters (e.q., via LPR GUI) while a print job is in progress. Known versions of CUPS server break the print
job whenever print options are changed and then try to restart the job from the beginning. Since Unified Linux Driver locks the port
while printing, the abrupt termination of the driver keeps the port locked and unavailable for subsequent print jobs. If this situation
occurs, try to release the port by selecting Release port in the Port configuration window.

Common PostScript problems
The following situations are PS language specific and may occur when several printer languages are used.
Problem Possible cause Solution
The PostScript file cannot be
printed.
The PostScript driver may not be installed
correctly.
• Install the PostScript driver (see "Software installation" on page 1).
• Print a configuration page and verify that the PS version is available for
printing.
• If the problem persists, contact a service representative.
Limit Check Error report prints. The print job was too complex. You might need to reduce the complexity of the page or install more memory.
A PostScript error page prints. The print job may not be PostScript. Make sure that the print job is a PostScript job. Check to see whether the software
application expected a setup or PostScript header file to be sent to the machine.
The optional tray is not
selected in the driver.
The printer driver has not been configured to
recognize the optional tray.
Open the PostScript driver properties, select the Device Options tab, and set the
tray option.

Glossary
Glossary
The following glossary helps you get familiar with the product by
understanding the terminologies commonly used with printing as well as
mentioned in this user’s guide.
802.11
802.11 is a set of standards for wireless local area network (WLAN)
communication, developed by the IEEE LAN/MAN Standards Committee (IEEE
802).
802.11b/g/n
802.11b/g/n can share same hardware and use the 2.4 GHz band. 802.11b
supports bandwidth up to 11 Mbps, 802.11n supports bandwidth up to 150
Mbps. 802.11b/g/n devices may occasionally suffer interference from
microwave ovens, cordless telephones, and Bluetooth devices.
Access point
Access Point or Wireless Access Point (AP or WAP) is a device that connects
wireless communication devices together on wireless local area networks
(WLAN), and acts as a central transmitter and receiver of WLAN radio signals.
ADF
An Automatic Document Feeder (ADF) is a scanning unit that will automatically
feed an original sheet of paper so that the machine can scan some amount of the
paper at once.
AppleTalk
AppleTalk is a proprietary suite of protocols developed by Apple, Inc for
computer networking. It was included in the original Macintosh (1984) and is
now deprecated by Apple in favor of TCP/IP networking.
BIT Depth
A computer graphics term describing the number of bits used to represent the
color of a single pixel in a bitmapped image. Higher color depth gives a broader
range of distinct colors. As the number of bits increases, the number of possible
colors becomes impractically large for a color map. 1-bit color is commonly
called as monochrome or black and white.
BMP
A bitmapped graphics format used internally by the Microsoft Windows
graphics subsystem (GDI), and used commonly as a simple graphics file format
on that platform.
Glossary
197
Glossary
BOOTP
Bootstrap Protocol. A network protocol used by a network client to obtain its IP
address automatically. This is usually done in the bootstrap process of
computers or operating systems running on them. The BOOTP servers assign
the IP address from a pool of addresses to each client. BOOTP enables 'diskless
workstation' computers to obtain an IP address prior to loading any advanced
operating system.
CCD
Charge Coupled Device (CCD) is a hardware which enables the scan job. CCD
Locking mechanism is also used to hold the CCD module to prevent any damage
when you move the machine.
Collation
Collation is a process of printing a multiple-copy job in sets. When collation is
selected, the device prints an entire set before printing additional copies.
Control Panel
A control panel is a flat, typically vertical, area where control or monitoring
instruments are displayed. They are typically found in front of the machine.
Coverage
It is the printing term used for a toner usage measurement on printing. For
example, 5% coverage means that an A4 sided paper has about 5% image or text
on it. So, if the paper or original has complicated images or lots of text on it, the
coverage will be higher and at the same time, a toner usage will be as much as
the coverage.
CSV
Comma Separated Values (CSV). A type of file format, CSV is used to exchange
data between disparate applications. The file format, as it is used in Microsoft
Excel, has become a de facto standard throughout the industry, even among
non-Microsoft platforms.
DADF
A Duplex Automatic Document Feeder (DADF) is a scanning unit that will
automatically feed and turn over an original sheet of paper so that the machine
can scan on both sides of the paper.
Default
The value or setting that is in effect when taking a printer out of its box state,
reset, or initialized.
Glossary
198
Glossary
DHCP
A Dynamic Host Configuration Protocol (DHCP) is a client-server networking
protocol. A DHCP server provides configuration parameters specific to the DHCP
client host requesting, generally, information required by the client host to
participate on an IP network. DHCP also provides a mechanism for allocation of
IP addresses to client hosts.
DIMM
Dual Inline Memory Module (DIMM), a small circuit board that holds memory.
DIMM stores all the data within the machine like printing data, received fax data.
DLNA
The Digital Living Network Alliance (DLNA) is a standard that allows devices on
a home network to share information with each other across the network.
DNS
The Domain Name Server (DNS) is a system that stores information associated
with domain names in a distributed database on networks, such as the Internet.
Dot Matrix Printer
A dot matrix printer refers to a type of computer printer with a print head that
runs back and forth on the page and prints by impact, striking an ink-soaked
cloth ribbon against the paper, much like a typewriter.
DPI
Dots Per Inch (DPI) is a measurement of resolution that is used for scanning and
printing. Generally, higher DPI results in a higher resolution, more visible detail
in the image, and a larger file size.
DRPD
Distinctive Ring Pattern Detection. Distinctive Ring is a telephone company
service which enables a user to use a single telephone line to answer several
different telephone numbers.
Duplex
A mechanism that will automatically turn over a sheet of paper so that the
machine can print (or scan) on both sides of the paper. A printer equipped with
a Duplex Unit can print on both sides of paper during one print cycle.
Duty Cycle
Duty cycle is the page quantity which does not affect printer performance for a
month. Generally the printer has the lifespan limitation such as pages per year.
The lifespan means the average capacity of print-outs, usually within the
warranty period. For example, if the duty cycle is 48,000 pages per month
assuming 20 working days, a printer limits 2,400 pages a day.
Glossary

Glossary
ECM
Error Correction Mode (ECM) is an optional transmission mode built into Class 1
fax machines or fax modems. It automatically detects and corrects errors in the
fax transmission process that are sometimes caused by telephone line noise.
Emulation
Emulation is a technique of one machine obtaining the same results as another.
An emulator duplicates the functions of one system with a different system, so
that the second system behaves like the first system. Emulation focuses on exact
reproduction of external behavior, which is in contrast to simulation, which
concerns an abstract model of the system being simulated, often considering its
internal state.
Ethernet
Ethernet is a frame-based computer networking technology for local area
networks (LANs). It defines wiring and signaling for the physical layer, and frame
formats and protocols for the media access control (MAC)/data link layer of the
OSI model. Ethernet is mostly standardized as IEEE 802.3. It has become the most
widespread LAN technology in use during the 1990s to the present.
EtherTalk
A suite of protocols developed by Apple Computer for computer networking. It
was included in the original Macintosh (1984) and is now deprecated by Apple
in favor of TCP/IP networking.
FDI
Foreign Device Interface (FDI) is a card installed inside the machine to allow a
third party device such as a coin operated device or a card reader. Those devices
allow the pay-for-print service on your machine.
FTP
A File Transfer Protocol (FTP) is a commonly used protocol for exchanging files
over any network that supports the TCP/IP protocol (such as the Internet or an
intranet).
Fuser Unit
The part of a laser printer that fuses the toner onto the print media. It consists of
a heat roller and a pressure roller. After toner is transferred onto the paper, the
fuser unit applies heat and pressure to ensure that the toner stays on the paper
permanently, which is why paper is warm when it comes out of a laser printer.
Glossary

Glossary
Gateway
A connection between computer networks, or between a computer network
and a telephone line. It is very popular, as it is a computer or a network that
allows access to another computer or network.
Grayscale
A shades of gray that represent light and dark portions of an image when color
images are converted to grayscale; colors are represented by various shades of
gray.
Halftone
An image type that simulates grayscale by varying the number of dots. Highly
colored areas consist of a large number of dots, while lighter areas consist of a
smaller number of dots.
HDD
Hard Disk Drive (HDD), commonly referred to as a hard drive or hard disk, is a
non-volatile storage device which stores digitally-encoded data on rapidly
rotating platters with magnetic surfaces.
IEEE
The Institute of Electrical and Electronics Engineers (IEEE) is an international
non-profit, professional organization for the advancement of technology
related to electricity.
IEEE 1284
The 1284 parallel port standard was developed by the Institute of Electrical and
Electronics Engineers (IEEE). The term "1284-B" refers to a specific connector
type on the end of the parallel cable that attaches to the peripheral (for example,
a printer).
Intranet
A private network that uses Internet Protocols, network connectivity, and
possibly the public telecommunication system to securely share part of an
organization's information or operations with its employees. Sometimes the
term refers only to the most visible service, the internal website.
IP address
An Internet Protocol (IP) address is a unique number that devices use in order to
identify and communicate with each other on a network utilizing the Internet
Protocol standard.
