Sequence of operation

Table 1-1 Sequence of operation
Period Duration Purpose Remarks
WAIT From the time the power is
turned on or the door is closed, until the printer is ready for a print operation
STBY (Standby period) From end of the WAIT or
LSTR period until either the print command is received from the formatter or the power is turned off
INTR (Initial rotation) From the time the print
command is received until the media is picked up
PRINT From the end of INTR period
until the fuser paper sensor detects the trailing edge of paper
LSTR (Last rotation) From the end of the PRINT
period until the delivery motor stops rotating
Clears the potential from the drum surface, adjusts the drum phase, and cleans the ITB
Maintains the printer in readiness for a print command
Prepares the photosensitive drum for printing
Forms the images on the photosensitive drum and transfers the toner image to the print media
Moves the printed sheet out of the printer
Detects the cartridge presence and environment; completes any required calibration (color registration control and image stability)
The printer enters sleep mode when the formatter sends a sleep command, and performs color registration and image stability control when the formatter sends those commands
Performs image stabilization at a specified print interval or at specified times
The printer enters the INTR period as soon as the formatter sends another print command

Laser/scanner system

The formatter sends video signals to the DC controller, which controls the laser/scanner. When the laser/scanner system receives those signals, it converts them to latent images on the photosensitive drum.

Image-formation system

The image-formation system forms a toner image on media. The product includes four toner cartridges that contain the toner. Toner is applied in the following order, using only the colors necessary for a specific image: yellow (Y), magenta (M), cyan (C), and black (K).

Image-formation process

Laser printing requires the interaction of several different technologies including electronics, optics, and electrographics to provide a printed page. Each process functions independently and must be coordinated with the other processes. Image formation consists of the following processes:
Latent-image formation
Development
Transfer

Latent-image formation stage

During the two steps that comprise this stage, a latent image is formed by applying a negative charge to the photosensitive drum. You cannot see this image on the drum.

Step 1: primary charging
A high-voltage DC bias is applied to the primary charging roller, which is made of conductive rubber and is in contact with the drum surface. As the roller moves across the drum, it applies the negative charge to that surface.

Step 2: laser-beam exposure
The laser beam scans the photosensitive drum to neutralize the negative charge on portions of the drum surface. An electrostatic latent image is formed where the negative charge was neutralized.

Step 3: development
Toner acquires a negative charge as a result of the friction from the developer roller rotating against the developer blade. When the negatively charged toner comes in contact with the drum, it adheres to the electrostatic latent image. When the toner is on the drum, the image becomes visible.

Step 4: primary transfer
The toner image on the photosensitive drum is transferred to the ITB. The DC positive bias is applied to the primary transfer pad. The negatively charged toner transfers to the ITB from the drum surface.

Step 5: secondary transfer
The toner image on the ITB is transferred to the print media. The DC positive bias is applied to the secondary transfer roller. As the media passes between the secondary transfer roller and the ITB, the toner image is transferred to the media.

Step 8: ITB cleaning
The ITB cleaning roller and the cleaning brush are applied with the DC positive bias to charge the residual toner positive. Because the primary transfer pad is also applied with the DC positive bias, the positively charged residual toner is reverse-transferred to the photosensitive drum from the ITB surface.

Drum cleaning stage

Not all of the toner is removed from the photosensitive drum during the transfer stage. During the cleaning stage, the residual, or waste, toner is cleared from the drum surface to prepare the surface for the next latent-image formation.
Step 9: drum cleaning
The cleaning blade scrapes the residual toner off the surface of the photosensitive drum and deposits it in the waste-toner container. The drum is now clear and is ready for the next image-formation process.

Scanner system (base models)

The flatbed image scanner captures an electronic image of the document on the glass. The scanner does this by illuminating the document with LEDs (red, green, and blue) and capturing the image in the image sensor to create an electronic format of the document. The flatbed scanner consists of three main elements
CIS scanner. The CIS (contact image sensor) scanner captures an image using the product's
optical path. Red, green, and blue LEDs sequentially illuminate a small strip of the document (often called a raster line), and the optical system captures each color in a single row of CCD sensors that cover the entire page width. Because only one color is captured for each line per exposure, the three colors are recombined electronically to create the full color image. For monochromatic scans or copies, all three LEDs are illuminated to create a white light for the scan so the raster line can be captured in one exposure.
Mechanical carriage drive. The carriage drive moves the CIS scan head along the document
length to create the image. In this product, a small DC motor with an optical encoder creates this motion. The speed of the carriage drive is proportional to the scan resolution (300 ppi is much faster than 1200 ppi) and also proportional to the type of scan (color scans are three-times slower than monochromatic scans). A 1200 ppi color scan moves so slowly that the product may appear to not be working, whereas a monochromatic copy scan moves at 50 times that speed and will be somewhat noisy.
Image processing system (formatter). The formatter processes the scanner data into either
a copy or a scan to the computer. For copies, the image data is sent directly to the product without being transmitted to the computer. Depending on user selections for the copy settings, the formatter enhances the scanner data significantly before sending it to the product. Image data is captured at 300 ppi for copies and is user selectable for scans to the computer. Each pixel is represented by 8 bits for each of the three colors (256 levels for each color), for a total of 24 bits per pixel (24-bit color).

Scanner power-on sequence of events

When the product is turned on, it performs the following tests:
Motor test. The product moves the motor left and right to confirm operation. It reports a scanner
error 12 if no motion is detected in the motor encoder system.
Wall find. The scan carriage moves slowly to the left while watching an encoder on the carriage
motor to determine when the carriage has found the side wall or stop. This enables the product to identify the document origin (position of the original). If the document origin cannot be located, a default position is used instead.
LED check. The product moves the carriage to the white calibration label under the left side of
the flatbed image scanner, and it verifies that the minimum and maximum response is acceptable. It reports a scanner error 14 if the response is unacceptable.
Home find. The scan carriage uses the optical scanner to find physical reference features that
relate to the document origin at the left side of the image glass. This process ensures accurate location of the first document pixels so that the user documents will have an accurate placement of
20 Chapter 1 Theory of operation ENWW
the image on scans and copies. It reports a scanner error 6 message if the reference features are not found.
Calibration. This test, also known as scanner color calibration, enables the product to identify
the black and white on every pixel in the CCD. Calibration occurs in two major processes: a broad (analog) adjustment of all pixels to bring them into the target output range, and a pixel-by­pixel adjustment (digital) to fine tune the actual black and white response. The calibration process occurs under the left side of flatbed image scanner where there is a special white calibration label.
Calibration is the most important step in creating a high quality image. Calibration problems can include color and brightness inaccuracies, and vertical streaks through the image. The calibration process identifies any bad pixels and enables the image formatter to recreate the lost information from adjacent pixels. Extreme cases of this problem can appear as large vertical streaks or image smears. The user has no control over the calibration process itself or this pixel-replacement process.

Copy or scan-to-computer sequence of events

To create an accurate rendition of a document, the scanner must be calibrated for the requested operation. If the user selects a scan at 600 ppi color, the flatbed image scanner calibrates for that specific operational mode. Subsequently, the flatbed image scanner automatically re-calibrates for the next requested operation. Calibration does not occur for every new copy request.
Normal sequence of operation for a flatbed copy or scan includes:
1. LEDs illuminate.
2. Carriage motion begins moving the CIS scanner toward the right.
3. Image capture continues for the entire page or length requested in a scan-to-computer operation.
4. Carriage returns to the home position on the left.

Fax functions and operation (fax models only)

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 on-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 signals appear on pins 3 and 4 of the RJ-11 modular jack (the one on the fax card, as defined in the common 6 wire RJ standard). These two signals do not have to be polarized because all of the equipment works with either TIP or RING on one pin and the other signal on the other pin. This means that cables of either polarity can interconnect and 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 using the PSTN.

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.
22 Chapter 1 Theory of operation ENWW
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.

Fax by using Voice over IP services

ENWW
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
Fax functions and operation (fax models only)
23
services are often not compatible with fax machines. The VoIP provider must state that the service supports fax over IP services.
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, low 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 product. 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 data access arrangement (DAA) to comply with worldwide 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 respective 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.
24 Chapter 1 Theory of operation ENWW
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.
Common mode protection is provided by the selection of high-voltage-barrier critical components (transformer 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 thyristor) provides differential protection. This device becomes low impedance at approximately 300 V differential, and crowbars to a low voltage. A series thermal switch works in conjunction with the crowbar for continuous telephone line events, such as crossed power lines.
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 through either a transformer 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.
ENWW
Fax functions and operation (fax models only)
25
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 dual RJ-11 jack). The DSP uses the signal to ensure that the product does not go off-hook (and disconnects a downstream call) until it has been authorized to do so (by a manual fax start or the detection of the appropriate tones).
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 work with the firmware to achieve the voltage-current characteristic between TIP and RING. The impedance (the current-voltage characteristic) changes corresponding to certain 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 billing 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.
26 Chapter 1 Theory of operation ENWW
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 7.5 MB is available for fax storage. The remaining 0.5 MB is used for the file system and reclamation. 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 resend the fax in case of errors. The product will resend stored fax pages after a busy signal, communication error, no answer, or power failure. Other fax devices store fax pages in either normal RAM or short­term 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.
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 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.

Internal print-quality test pages

Interpret the Print Quality Page
1. On the product control panel, open the Reports menu.
2. Select the Print Quality Page item to print it.
This page contains five bands of color, which are divided into four groups as indicated in the following illustration. By examining each group, you can isolate the problem to a particular print cartridge.
Section Print-cartridge
1Yellow
2Cyan
44 Chapter 2 Solve problems ENWW
Section Print-cartridge
3Black
4Magenta
If dots or streaks appear in only one of the groups, replace the print cartridge that correlates with
that group.
If dots appear in more than one group, print a cleaning page. If this does not solve the problem,
determine if the dots are always the same color; for example, if magenta dots appear in all five color bands. If the dots are all the same color, replace that print cartridge.
If streaks appear in multiple color bands, contact HP. A component other than the print cartridge is
probably causing the problem.
Print a cleaning page
Print a cleaning page to remove dust and excess toner from the paper path if you are having any of the following problems:
Specks of toner are on the printed pages.
Toner is smearing on the printed pages.
Repeated marks occur on the printed pages.
Print a cleaning page
1. From the Home screen on the product control panel, touch the Setup
2. Touch the Service menu.
3. Touch the Cleaning Page button.
4. Load plain letter or A4 paper when you are prompted.
5. Touch the OK button to begin the cleaning process.
6. The product prints the first side and then prompts you to remove the page from the output bin and
reload it in Tray 1, keeping the same orientation (the side with the black stripe should be face­down with the arrow toward the back of the product).
7. Press the OK button to continue the cleaning process. Wait until the process is complete. Discard

Repetitive image defects
If the product output has a consistent, repetitive defect, use the table in this section to determine which part needs to be replaced based on the measured distance between the repetitions of the defect.
NOTE: The following table replaces the graphical repetitive defect ruler. You can make your own
ruler by using these measurements. For the most accurate results, use a metric ruler.

All print defects or cartridge failures incurred when an HP supply is used in Continue at very low mode will not be considered to be defects in materials or workmanship in the supply under the HP Print Cartridge Warranty Statement.
