The priority input tray holds up to 10 sheets of 75 g/m2 (20 lb) media or one envelope, one transparency,
or one card. You can use the priority input tray to print the first page on media different from the remainder
of the document.
Media guides ensure that the media is correctly fed into the product and that the print is not skewed
(crooked on the media). When loading media, adjust the media guides to match the width of the media
that you are using.
ENWW Load paper and print media 23
Tray 1
Tray 1 holds up to 250 pages of 75 g/m2 (20 lb) paper, or fewer pages of heavier media (25 mm (0.9 in)
or less stack height). Load media with the top forward and the side to be printed on facing down.
Media guides ensure that the media feeds correctly into the product and that the print is not skewed.
Tray 1 has side and rear media guides. When loading media, adjust the media guides to match the
length and width of the media that you are using.
NOTE: When you add new media, make sure that you remove all of the media from the input tray and
straighten the stack of new media. Do not fan the media. This reduces jams by preventing multiple
sheets of media from feeding through the product at one time.

Formatter system
The formatter coordinates the major systems. It is responsible for the following tasks or actions:
Formatting and controlling copies
●
Receiving and processing print data from the product interface
●
Monitoring the control panel and relaying product-status information
●
Developing and coordinating data placement and timing with the print engine
●
Communicating with the host computer through the bidirectional interface
●
Communicating fax data to and from the fax card
●
The formatter receives print data from the USB interface and converts it into a dot image. The ECU
synchronizes the image-formation system with the paper-feed system and signals the formatter to send
the print-image data. The formatter sends the print-image data (dots) in the form of a video signal, and
the printing process begins.
Central processing unit
The formatter incorporates an embedded Xtensa processor operating at 240 MHz.
Fax card
The fax card provides the required safety isolation, signal coupling, and global impedance matching and
analog to digital conversion of incoming and outgoing fax data.
ENWW Formatter system 41
Standard startup process
When the product is unplugged or the power is off, the firmware code is stored on the formatter in two
blocks. The first block of code is an executable boot block (about 64K of code). The second block of
code is a compressed version of the product control code.
When the product is turned on, the boot block decompresses the product control code and stores it in
RAM. Then the product performs a full startup with the control code running from RAM.
Product startup messages
The LCD display contains different messages depending upon the progress of the boot process.

Power system on the power-supply assembly
The power-supply assembly supplies the AC, DC, and high-voltage power-supply circuits.
AC power distribution
The AC power circuitry supplies AC voltage whenever the power cord is connected to the AC power
source and the power switch is on. The AC voltage is distributed to the DC power-supply circuitry and
to the AC driver circuitry, which controls AC voltage to the fuser-assembly heating element.
DC power distribution
The DC power distribution circuitry, located on the printer (product base) power assembly, distributes

High-voltage power distribution
The high-voltage power supply applies an overlap of DC and AC voltage to the primary charging roller
and to the developing roller. This circuit also applies a positive or negative DC voltage to the transfer
roller according to the instructions from the ECU.
This circuit also controls the image density by changing the primary AC voltage and the developing AC
bias according to the print-density setting (which is set by using the print driver). High voltage is disabled
when the print-cartridge door is open.

Image-formation system
Laser printing requires the interaction of several different technologies including electronics, optics, and
electrophotographics to provide a printed page. Each process functions independently and must be
coordinated with the other product processes. Image formation consists of seven processes:
Figure 5-5 Image-formation block diagram
Writing Stage
Flow of paper
Direction of drum rotation
1. Primary charging
Drum cleaning
stage
Paper delivery
Fusing stage
6. Fusing
7. Drum cleaning
The seven image-formation processes
1. Conditioning stage (primary charging)—This process applies a uniform negative charge to the
surface of the drum with the primary charging roller, which is located in the print cartridge. The
primary charging roller is coated with conductive rubber. An AC bias is applied to the roller to erase
any residual charges from any previous image. In addition, the primary charging roller applies a
negative DC bias to create a uniform negative potential on the drum surface. The print density
setting modifies the DC voltage.
2. Writing stage (scanning exposure)—During this process, a modulated laser diode projects the
beam onto a rotating scanning mirror. As the mirror rotates, the beam reflects off the mirror, first
through a set of focusing lenses, then off a mirror, and finally through a slot in the top of the print
cartridge, and onto the photosensitive drum. The beam sweeps the drum from left to right,
discharging the negative potential wherever the beam strikes the surface. This creates a latent
electrostatic image, which later is developed into a visible image. Because the beam sweeps the
entire length of the drum while the drum rotates, the entire surface area of the drum can be covered.
At the end of each sweep, the beam strikes the beam-detect lens, generating the beam-detect
signal (BD signal). The BD signal is sent to the ECU, where it is converted to an electrical signal

3. Developing stage—During this process, the latent electrostatic image is present on the drum. The
toner particles obtain a negative surface charge by rubbing against the developing cylinder, which
is connected to a negative DC supply. The negatively charged toner is attracted to the discharged
(exposed and grounded) areas of the drum, and it is repelled from the negatively charged
(unexposed) areas.
4. Transfer stage—During this process, the toner image on the drum surface is transferred to the
media. The transfer roller applies a positive charge to the back of the media, which attracts the
negatively charged toner on the drum surface to the media. After separation, the drum is cleaned
and conditioned for the next image.
5. Separation stage—During this process, the media separates from the drum. To stabilize the feed
system and prevent toner dropouts on the printed image at low temperature and humidity, the static
eliminator reduces the charge on the back of the media.
48 Chapter 5 Operational theory ENWW
6. Fusing stage—During this process, the heat and pressure fuse the toner into the media to produce
a permanent image. The media passes between a heated fusing element and a soft pressure roller,
which melt the toner and press it into the media.
7. Drum-cleaning stage—During this process, the cleaning blade is in contact with the surface of
the drum at all times. As the drum rotates during printing, the cleaning blade wipes excess toner
off the drum and stores it in the waste toner receptacle.
Print cartridge
As the focal point of the image-formation system, the print cartridge contains toner and houses the
cleaning, conditioning, and developing stages of the process. The print cartridge contains the
photosensitive drum, primary charging roller, developing station, toner cavity, and cleaning station. By
including these components (which wear, degrade, or are consumed) in the replaceable print cartridge,
the need for many service calls is eliminated. The special photosensitive properties of the drum form
an image on the drum surface and then transfer the image to media.
CAUTION: The print cartridge does not include a light-blocking shutter. Do not expose the drum to
light, which can permanently damage the drum. Protect the print cartridge whenever you remove it by
covering it with paper.
Product base paper-feed system
The main input tray and the priority input tray merge into one main input area. The product uses the topof-page sensor (PS801) to senses the paper as it enters the paper-feed path. It does not sense the
presence of media before beginning the print cycle. The following steps occur when the product receives
a print job.
Step 1 The ECU activates the motor (M1). Paper motion begins when the ECU energizes the pickup solenoid
Step 2 The pickup roller rotates once. The-lift plate pushes the media against the pickup roller.
Step 3 The friction of the pickup roller grabs the top sheet and advances it to the feed-assembly drive rollers. To

the photosensitive drum is transferred to the media.
ENWW Product base functions 49
Step 6 After the image is transferred, the media enters the fuser assembly where heat from the fuser and pressure
from the pressure roller permanently bond the toner image to media. The paper-delivery sensor (PS803)
determines that the media has successfully moved out of the fusing area.
Step 7 The fuser-assembly exit rollers deliver media to the output bin face-down.

Jam detection in the product
The top-of-page sensor (PS801) and the paper-delivery sensor (PS803) detect media moving through
the product. If a jam is detected, the ECU immediately stops the printing process and the Attention
(Cancel) light illuminates on the control panel.

HP LaserJet M1319f components
This section presents an overview of the relationships between unique major components in the HP
LaserJet M1319f. This section describes the optical scanning system and ADF pickup and feed system
used in the product. . For information about image formation, see
on page 48.
Basic operation
The HP LaserJet M1319f uses a pickup and feed system (document transportation) and an optical
scanning system.
two systems.

Figure 5-7 Basic operation block diagram on page 52 shows the relationship of the
Image-formation system
A document is placed into the ADF tray. When the formatter sends a signal to the optical scanning
system, the document is picked up and fed into the optical system through a series of rollers and a
separation pad. The separation pad prevents the pickup system from feeding multiple pages if more
than one page is loaded in the ADF tray.
As the document passes the contact image scanner, the scanner illuminates the document. The optical
scanning system captures and amplifies the reflected light and converts it to a digital signal, and then
sends the digital signal to the formatter for image-processing.

ENWW HP LaserJet M1319f components 53
ADF pickup-and-feed system
The ADF pickup-and-feed system uses a pickup roller, a feed roller, and a delivery roller to transport
the document into, through, and out of the optical scanning system. The optical scanning system motor
drives the rollers when the formatter signals the optical scanning system that a job to print or copy is
present.
The ADF pickup-and-feed path has two sensors. The document sensor (PS1201) detects the presence
of a document in the ADF input tray. The document-top sensor (PS202) detects the document in the
ADF paper path. The formatter processes the signals from the sensors and the product operates
accordingly.
When the contact image scanner motor rotates, it causes the pickup, feed, and delivery rollers to rotate.
The ADF document pickup roller pushes a document into the ADF paper path. The separation pad
prevents multiple pages from entering the ADF paper path by creating friction against the document and
the pickup roller. The document feed roller advances the document past the contact image sensor (CIS).
The document delivery roller advances the document out of the ADF paper path to the output area.
Figure 5-9 Feed control (1 of 2)
The contact image scanner motor drives the pickup roller, the feed roller, a one-way clutch, and the
delivery roller. A gear differential causes the pickup roller to rotate at a slower speed than the feed roller.
The slower speed allows for a consistent space between pages of a multiple-page document, which is
54 Chapter 5 Operational theory ENWW
necessary for correct document scanning. The one-way clutch varies the rotation speeds of the pickup
roller and feed roller to prevent the rollers from tearing the document.
Figure 5-10 Feed control (2 of 2)
ENWW HP LaserJet M1319f components 55
Optical scanning system
The contact image sensor (CIS) is the major component of the optical scanning system. The CIS
consists of three LEDs (red, green, and blue), a light guide, the scanning glass, the rod lens array, and
a sensor array. When the CIS scans a document, the CIS does not move. Instead, documents move
past the CIS.
Figure 5-11 Optical system (1 of 2)
The formatter controls the CIS. To begin scanning, the formatter sends a signal to the CIS. The LEDs
illuminate and the light passes through the light guide and scanning glass and strikes the document.
Light that the document reflects passes back through the scanning glass and rod lens array into the
sensor array. The sensor array consists of 5,148 photosensors (468 photosensors on each of 11 sensor
driver circuits). The sensor array collects and amplifies the reflected light and converts it into serial data
in the driver circuits. The CIS sends the data to the formatter for image formation.

Fax functions and operation
The following sections describe the product fax capabilities.
Computer and network security features
The product can send and receive fax data over telephone lines that conform to public switch telephone
network (PSTN) standards. The secure fax protocols make it impossible for computer viruses to be
transferred from the telephone line to a computer or network.
The following product features prevent virus transmission:
No direct connection exists between the fax line and any devices that are connected to the USB
●
or Ethernet ports.
The internal firmware cannot be modified through the fax connection.
●
All fax communications go through the fax subsystem, which does not use Internet data-exchange
●
protocols.
PSTN operation
The PSTN operates through a central office (CO) that generates a constant voltage on the TIP and
RING wires (48 V, usually). A device goes off-hook by connecting impedance (such as 600 ohms for
the U.S.) across the TIP and RING so that a line current can flow. The CO can detect this current and
can send impulses like dial tones. The product generates more signaling tones, such as dialing digits,
to tell the CO how to connect the call. The product can also detect tones, such as a busy tone from the
CO, that tell it how to behave.
When the call is finally connected, the CO behaves like a piece of wire connecting the sender and
receiver. This is the period during which all of the fax signaling and data transfer occurs. When a call is
completed, the circuit opens again and the line-current flow ceases, removing the CO connection from
both the sender and the receiver.
On most phone systems, the TIP and RING wires appear on pins 3 and 4 of the RJ-11 modular jack
(the one on the fax card). These two wires do not have to be polarized because all the equipment works
with either TIP or RING on pin 3 and the other wire on pin 4. This means that cables of either polarity
can interconnect and will still work.
These basic functions of PSTN operation are assumed in the design of the fax subsystem. The product
generates and detects the signaling tones, currents, and data signals that are required to transmit and
receive faxes on the PSTN.
58 Chapter 5 Operational theory ENWW
Receive faxes when you hear fax tones
In general, incoming faxes to the product are automatically received. However, if other devices are
connected to the same phone line, the product might not be set to answer automatically.
If the product is connected to a phone line that receives both fax and phone calls, and you hear fax
tones when you answer the extension phone, receive the fax in one of two ways:
If you are near the product, press Start Fax on the control panel.
●
Press 1-2-3 in sequence on the extension phone keypad, listen for fax transmission sounds, and
●
then hang up.
NOTE: In order for the 1-2-3 sequence to work, the extension phone setting must be set to On in the
Fax setup menu.
Distinctive ring function
Distinctive ring is a service that a telephone company provides. The distinctive ring service allows three
phone numbers to be assigned to one phone line. Each phone number has a distinctive ring. The first
phone number has a single ring, the second phone number has a double ring, and the third phone
number has a triple ring.
NOTE: The product has not been tested with all of the distinctive-ring services that telephone
companies provide in all countries/regions. HP does not guarantee that the distinctive-ring function will
operate correctly in all countries/regions. Contact the local phone service provider for assistance.
Set up the distinctive ring function
1. Press Setup. Use the arrow buttons to select Fax setup and then press OK.
2. Use the arrow buttons to select Fax recv. setup and then press OK.

Press OK to save the setting.
Fax by using Voice over IP services
Voice over IP (VoIP) services provide normal telephone service, including long distance service through
a broadband Internet connection. These services use packets to break up the voice signal on a
telephone line and transmit it digitally to the receiver, where the packets are reassembled. The VoIP
services are often not compatible with fax machines. The VoIP provider must state the service supports
fax over IP services.
ENWW Fax functions and operation 59
Because the installation process varies, the VoIP service provider will have to assist in installing the
product fax component.
Although a fax might work on a VoIP network, it can fail when the following events occur:
Internet traffic becomes heavy and packets are lost.
●
Latency (the time it takes for a packet to travel from its point of origin to its point of destination)
●
becomes excessive.
If you experience problems using the fax feature on a VoIP network, ensure that all of the product cables
and settings are correct. Configuring the Fax Speed setting to Medium(V.17) or Slow(V.29) can also
improve your ability to send a fax over a VoIP network.
If you continue to have problems faxing, contact your VoIP provider.
The fax subsystem
The formatter, fax card, firmware, and software all contribute to the fax functionality. The designs of the
formatter and fax card, along with parameters in the firmware, determine the majority of the regulatory
requirements for telephony on the product.
The fax subsystem is designed to support V.34 fax transmission, lower speeds (such as V.17 fax), and
older fax machines.
Fax card in the fax subsystem
Two versions of the fax card are used in the HP LaserJet M1319 MFP. One is used in the North
American, South American, and Asian countries/regions. The other is used primarily in European
countries/regions.
The fax card contains the modem chipset (DSP and CODEC) that controls the basic fax functions of
tone generation and detection, along with channel control for fax transmissions. The CODEC and its
associated circuitry act as the third-generation silicon DAA to achieve compliance world-wide regulatory
requirements.
The only difference between the two versions is that each version is compliant with the 2/4-wire phone
jack system from the repective country/region.
Safety isolation
The most important function of the fax card is the safety isolation between the high-voltage, transientprone environment of the telephone network (TNV [telephone network voltage]) and the low-voltage
analog and digital circuitry of the formatter (SELV [secondary extra-low voltage]). This safety isolation
provides both customer safety and product reliability in the telecom environment.
Any signals that cross the isolation barrier do so magnetically. The breakdown voltage rating of barriercritical components is greater than 5 kV.
Safety-protection circuitry
In addition to the safety barrier, the fax card protects against over-voltage and over-current events.
Telephone over-voltage events can be either differential mode or common mode. The event can be
transient in nature (a lightning-induced surge or ESD) or continuous (a power line crossed with a phone
line). The fax card protection circuitry provides margin against combinations of over-voltage and overcurrent events.
60 Chapter 5 Operational theory ENWW
Common mode protection is provided by the selection of high-voltage-barrier critical components
(capacitor and relay). The safety barrier of the fax card PCB traces and the clearance between the fax
card and surrounding components also contribute to common mode protection.
A voltage suppressor (a crowbar-type SIDACTOR) provides differential protection. This device becomes
low impedance at approximately 300 V differential, and crowbars to a low voltage.
All communications cross the isolation barrier magnetically. The breakdown voltage rating of barriercritical components is greater than 5 kV.
Data path
TIP and RING are the two-wire paths for all signals from the telephone network. All signaling and data
information comes across them, including fax tones and fax data.
The telephone network uses DC current to determine the hook state of the telephone, so line current
must be present during a call. The silicon DAA provides a DC holding circuit to keep the line current
constant during a fax call.
The silicon DAA converts the analog signal to a digital signal for DSP processing, and also converts the
digital signal to an analog signal for transmitting data through a telephone line.
The magnetically coupled signals that cross the isolation barrier go either through a capacitor or a relay.
The DSP in the fax card communicates with the ASIC in the formatter using the high-speed serial
interface.
Hook state
Another magnetically coupled signal is the control signal that disconnects the downstream telephone
devices (such as a phone or answering machine). A control signal originating on the DSP can change
the relay state, causing the auxiliary jack (downstream jack) to be disconnected from the telephone
circuit.
The product takes control of calls that it recognizes as fax calls. If the product does not directly pick up
the call, it monitors incoming calls for the fax tone or for the user to direct it to receive a fax. This idle
mode is also called eavesdropping. This mode is active when the product is on-hook but current exists
in the downstream phone line because another device is off-hook. During eavesdropping, the receive
circuit is enabled but has a different gain from the current that is generated during normal fax
transmissions.
The product does not take control of the line unless it detects a fax tone or the user causes it to connect
manually. This feature allows the user to make voice calls from a phone that is connected to the product
without being cut off if a fax is not being received.
Downstream device detection
The line voltage monitoring module of the silicon DAA can detect the line state as well as the downstream
device. It tells DSP via DIB that an active device (telephone, modem, or answering machine) is
connected to the auxiliary port on the product (the right side of the RJ-11 jack). The DSP uses the signal
to ensure that the product does not go off-hook (and disconnect a downstream call) until it has been
authorized to do so (by a manual fax start or the detection of the appropriate tones).
ENWW Fax functions and operation 61
Hook switch control
In the silicon DAA the CODEC controls the hook switch directly. The CODEC is activated when it
receives commands from the DSP. When the circuit is drawing DC current from the central office it is
considered off-hook. When no DC current flows the state is considered on-hook.
Ring detect
Ring detect is performed by the line voltage monitoring module of the silicon DAA, and is a combination
of voltage levels and cadence (time on and time off). Both must be present to detect a valid ring. The
CODEC works with DSP as well as the firmware to determine if an incoming signal is an answerable
ring.
Line current control
The DC current from the CO needs to have a path to flow from TIP to RING. The DC impedance
emulation line modulator and DC terminations modules in the silicon DAA act as a DC holding circuit,
and works with the firmware to achieve the voltage-current characteristic between TIP and RING. The
impedance (the current-voltage characteristic) changes corresponding to certian special events, such
as pulse dialing or when the product goes on-hook.
Billing- (metering-) tone filters
Switzerland and Germany provide high-frequency AC signals on the phone line in order to bill customers.
A filter in a special fax cable (for certain countries/regions), can filter these signals. Because these
billings signals are not used in the U.S., these filters are not present in the U.S. fax cable.
To obtain a special fax cable, contact your local telephone service provider.
Fax page storage in flash memory
Fax pages are the electronic images of the document page. They can be created in any of three ways:
scanned to be sent to another fax machine, generated to be sent by the computer, or received from a
fax machine to be printed.
The product stores all fax pages in flash memory automatically. After these pages are written into flash
memory, they are stored until the pages are sent to another fax machine, printed on the product,
transmitted to the computer, or erased by the user.
These pages are stored in flash memory, which is the nonvolatile memory that can be repeatedly read
from, written to, and erased. The product has 8 MB of flash memory, of which 5 MB is available for fax
storage. The remaining 3 MB is used for Phonebook and code storage. Adding RAM does not affect the
fax page storage because the product does not use RAM for storing fax pages.
Stored fax pages
The user can reprint stored fax receive pages in case of errors. For a fax send, the product will re-send
the fax in case of errors. The product will re-send stored fax pages after a busy signal, comm error, no
answer, or power failure. Other fax devices store fax pages in either normal RAM or short-term RAM.
Normal RAM immediately loses its data when power is lost, while short-term RAM loses its data about
60 minutes after power failure. Flash memory maintains its data for years without any applied power.
62 Chapter 5 Operational theory ENWW
Advantages of flash memory storage
Fax pages that are stored in flash memory are persistent. They are not lost as a result of a power failure,
no matter how long the power is off. Users can reprint faxes in case the print cartridge runs out of toner
or the product experiences other errors while printing faxes.
The product also has scan-ahead functionality that makes use of flash memory. Scan-ahead
automatically scans pages into flash memory before a fax job is sent. This allows the sender to pick up
the original document immediately after it is scanned, eliminating the need to wait until the fax is
transmission is complete.
Because fax pages are stored in flash memory rather than RAM, more RAM is available to handle larger
and more complicated copy and print jobs.

Removal and replacement strategy
This chapter documents the removal and replacement of field replaceable units (FRUs) only.
Replacing FRUs is generally the reverse of removal. Occasionally, notes and tips are included to provide
directions for difficult or critical replacement procedures.
HP does not support repairing individual subassemblies or problem-solving at the component level.
Note the length, diameter, color, type, and location of each screw. Be sure to return each screw to its
original location during reassembly.
Incorrectly routed or loose wire harnesses can interfere with other internal components and can become
damaged or broken. Frayed or pinched harness wires can be difficult to locate. When replacing wire
harnesses, always use the provided wire loops, lance points, or wire-harness guides.
Warnings, cautions, notes, and tips
WARNING! Turn the product off, wait 5 seconds, and then remove the power cord before attempting
to service the product. If this warning is not followed, severe injury can result, as well as damage to the
product. The power must be on for certain functional checks during problem solving. However, the power
supply should be disconnected during parts removal.
Never operate or service the product with the protective cover removed from the laser/scanner
assembly. The reflected beam, although invisible, can damage your eyes.
The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.
CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do
not straighten pre-folds in the FFCs. You must make sure that all FFCs are fully seated in their
connectors. Failure to fully seat an FFC into a connector can cause a short circuit in a PCA.
NOTE: To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread
pattern, and then carefully turn it clockwise to tighten. Do not overtighten. If a self-tapping screw hole
becomes stripped, repair the screw hole or replace the affected assembly.
Electrostatic discharge
CAUTION: Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD
reminder when removing product parts. Always perform service work at an ESD-protected workstation
