Sequence of operation
Table 1-1 Sequence of operation
Period Duration
WAIT From the time the power is turned on or the door is closed until the drum-phase adjustment is complete
STBY (Standby period)
INTR (Initial rotation)
From end of the WAIT or LSTR period until either the print command is received from the formatter or the power is turned off
Purpose
Clears the potential from the drum surface, adjusts the drum phase, and cleans the intermediate transfer belt (ITB)
Maintains the product in readiness for a print command
Prepares the photosensitive drum for printing
Remarks
Detects the toner level, cartridge presence, and environment; completes any required calibration (color registration control and image stability)
The product enters STBY mode when the formatter sends a sleep command; the product performs color registration and the image stability control when the formatter sends those commands
LSTR (Last rotation)
From the time the print command is received until the paper is picked up
From the end of INTR period until the fuser paper sensor detects the trailing edge of paper
From the end of the PRINT period until the motor stops rotating
Forms the images on the photosensitive drum and transfers the toner image to the paper
Moves the printed sheet out of the product
Performs image stabilization at a specified print interval or at specified times
The product enters the INTR period as soon as the formatter sends another print command
ENWW Basic operation 3
Formatter-control system
The formatter is responsible for the following procedures:
●
Controlling Sleep mode
● Receiving and processing print data from the various product interfaces
●
Monitoring control-panel functions and relaying product-status information (through the control panel and the network or bidirectional interface)
● Developing and coordinating data placement and timing with the DC controller PCA
●
Storing font information
● Communicating with the host computer through the network or the bidirectional interface
The formatter receives a print job from the network or bidirectional interface and separates it into image information and instructions that control the printing process. The DC controller PCA synchronizes the imageformation system with the paper-input and -output systems, and then signals the formatter to send the print-image data.
Sleep mode
After a user-specified time, the Sleep mode feature automatically conserves electricity by substantially reducing power consumption when the product is not printing. After a user-specified time, the product automatically reduces its power consumption (Sleep mode). The product returns to the ready state when a button is pressed, a print job is received, or a door is opened. When the product is in Sleep mode, all of the control-panel LEDs and the power button backlight LED are off.
Input/output
The product receives print data primarily from the following:
● Hi-Speed USB 2.0 port
●
10/100/1000 Ethernet LAN connection
● 802.11b/g/n wireless networking
CPU
The formatter incorporates a 600 MHz Arm processor.
Memory
The random access memory (RAM) on the formatter PCA contains the page, I/O buffers, and the font storage area. RAM stores printing and font information received from the host system, and can also serve to temporarily store a full page of print-image data before the data is sent to the print engine.
NAND Flash memory
The Smart Install CD image (ISO) is stored in the NAND Flash non-volatile memory. This memory can be reprogrammed through the firmware.
4 Chapter 1 Theory of operation ENWW
Firmware
The product has 128 MB of DDR-2 SDRAM, which is used for run-time firmware imaging and print, scan and copy job information during printing.
Memory use
The product has a 16 KB EEPROM and 16 MB of SPI NOR Flash Memory, which is used for product configuration information and print driver firmware.
PJL overview
The print job language (PJL) is an integral part of configuration, in addition to the standard print command language (PCL). With standard cabling, the product can use PJL to perform a variety of functions such as these:
●
Two-way communication with the host computer through a network connection or a USB connection.
The product can inform the host about such things as the control-panel settings, and the control-panel settings can be changed from the host.
● Dynamic I/O switching. The product uses this switching to be configured with a host on each I/O. The product can receive data from more than one I/O simultaneously, until the I/O buffer is full. This can occur even when the product is offline.
●
Context-sensitive switching. The product can automatically recognize the personality (PS or PCL) of each job and configure itself to serve that personality.
● Isolation of print environment settings from one print job to the next. For example, if a print job is sent to the product in landscape mode, the subsequent print jobs print in landscape mode only if they are formatted for landscape printing.
LEDM overview
The low-end data model (LEDM) provides one consistent data representation method and defines the dynamic and capabilities tickets shared between clients and devices, as well as the access protocol, event, security, and discovery methods.
Control panel
The formatter sends and receives product status and command data to and from the control-panel PCA.
ENWW Formatter-control system 5

Image-formation process
ENWW Image-formation system 13
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. This image is not visible 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.
Figure 1-8
Primary charging
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.
Figure 1-9
Laser-beam exposure
14 Chapter 1 Theory of operation ENWW
Developing stage
The developing cylinder comes in contact with the photosensitive drum and deposits toner on the electrostatic latent image.
Step 3: Development
The toner acquires a negative charge as a result of the friction from the developing cylinder rotating against the developing 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.
Figure 1-10
Development
ENWW Image-formation system 15
Transfer stage
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.
Figure 1-11
Primary transfer brush
Step 5: Secondary transfer
The toner image on the ITB is transferred to the paper. The DC positive bias is applied to the secondary transfer roller. As the paper passes between the secondary transfer roller and the ITB, the toner image is transferred to the paper.
Figure 1-12
Secondary transfer
16 Chapter 1 Theory of operation ENWW
Step 6: Separation from the drum
The elasticity of the paper and the curvature of the ITB drive roller cause the paper to separate from the ITB.
Figure 1-13
Separation from the drum
Fusing stage
Until the fusing stage is complete, the image is not permanently affixed to the paper. The toner can be easily smudged until the heat and pressure of the fusing process fix the image to the sheet.
Step 7: Fusing
The product uses an on-demand fusing method to fix the toner image onto the paper. The toner image is permanently affixed to the paper by the heat and pressure.
Figure 1-14
Fusing
ENWW Image-formation system 17
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 8: 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.
Figure 1-15
Drum cleaning
ITB cleaning mechanism
The ITB cleaning mechanism cleans the ITB surface.
Negative or positive bias is applied to the T1 pad, ITB cleaning brush, T2 roller and ITB cleaning roller to reverse transfer the residual toner on the ITB to the photosensitive drum. The reverse transferred residual toner is deposited in the toner collection box in the imaging drum.
Figure 1-16
ITB cleaning mechanism
The residual toner on the T2 roller, ITB cleaning brush and ITB cleaning roller is also deposited in the toner collection box during the ITB cleaning operation.
The DC controller executes the ITB cleaning during the following periods:

Scanner system
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 a little 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).
Electrical system
Scanner power-on sequence of events
When the product is turned on, it performs the following tests:
●
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 left 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.
● 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 the image on scans and copies. If the reference feature is not found, it uses a default value.
●
Calibration. This test, also known as scanner color calibration, enables the product to identify the black and white on every pixel in the CIS. Calibration occurs in two major processes: a broad (analog) adjustment of all pixels to bring them into the target output range, and a pixel-by-pixel 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 inaccuracies, 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.
Turn the product on or perform a color calibration to force a scanner calibration. Scanner calibration occurs with each of these events.
ENWW Scanner system 23
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.
24 Chapter 1 Theory of operation ENWW
Document feeder functions and operation
The following sections describe how the document feeder functions.
Document feeder operation
Standby (paper-loading) mode: In standby mode, the stopper will be lowered to prevent the user from inserting the original document too far. When a document is inserted correctly, the CIS will detect its presence by the Flag_document status.
The standard operation of the document feeder consists of the pick and feed steps.
Pick: When it receives a copy or scan command, the SSA motor engages the gear train to release the stopper.
The first roller, called the pre-pick roller, moves the top few sheets forward into the document feeder. The next roller is the pickup roller. This roller contacts the document feeder separation pad, which separates multiple pages into single sheets.
Feed: The single sheet continues through the path. Along the way, the TOF sensor, which is a set distance from the document feeder glass, detects the sheet. This alerts the scanner to start when the page reaches the glass. The scanner acquires the image, one raster line at a time, until it detects the end of the page. The page is then ejected. The pick and feed steps are repeated as long as no paper is detected by the TOF sensor.
The document feeder will not function when the document feeder cover is open. The paper path is incomplete if the document feeder cover is lifted from the glass.

Item Description
TOF/BOF sensor
Flag_document part
The CIS will detect the presence of the paper from the flag_document (callout 2) status. The document feeder has one sensor that detects paper. If paper is in the document feeder, the TOF sensor (callout 1) detects the top and bottom edges of the document. The TOF sensor detects media moving through the document feeder. If a jam is detected, the document feeder immediately stops the paper from feeding and a jam message is displayed on the control-panel display.
Document feeder functions and operation 25
Document feeder jam detection
The document feeder has one sensor that detects paper. The TOF sensor detects media moving through the document feeder. If a jam is detected, the document feeder immediately stops the paper feeding and a jam message appears on the control-panel display.
A jam can be detected under any of the following conditions:
● Document-feeder jam. When documents are detected in the document feeder input tray, and a command to copy, scan or fax is received, the scan module travels to the left side of the scan assembly and stops beneath the document feeder scanner glass. The document feeder then attempts three times, or for about ten seconds, to advance the paper to the TOF sensor. If the paper does not advance, the scan module travels back to the home position on the right side of the scanner assembly. The message Document feeder mispick. Reload. appears on the control-panel display.
●
Long-document jam. If the paper has advanced to trigger the TOF sensor, but the trailing edge is not detected within the time allowed for a 381 mm (15 in) document (the maximum allowable page length for the document feeder), the scanner returns to the home position on the right side of the scanner assembly. The message Doc feeder jam. Clear, Reload. appears on the control-panel display.
● Stall jam. When a page that is less than 381 mm (15 in) long has advanced to the TOF sensor but has not left it within the expected time, the paper has probably stalled or jammed. The scanner returns to the home position on the right side of the scanner assembly. The message Doc feeder jam. Clear,
Reload. appears on the control-panel display.
●
Other. If the paper stops in the document feeder and the scan module remains under the document feeder scanner glass, an internal firmware error has probably occurred. This is usually remedied by cycling the power.
26 Chapter 1 Theory of operation ENWW
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 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 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.
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
Three versions of the fax card are used in the product. One for Asia Pacific Countries/Regions and the United
States, one for Europe, and one for Brazil. Each version is compliant with the 2/4-wire phone jack system from the respective country/region.
ENWW Fax functions and operation 27
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.
Safety isolation
The most important function of the fax card is the safety isolation between the high-voltage, transient-prone 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 over-current 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 SIDACTOR) provides differential protection. This product 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 barrier-critical 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 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.
28 Chapter 1 Theory of operation ENWW
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).
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 offhook. 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 currentvoltage 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 the 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.
ENWW Fax functions and operation 29
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 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.
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 toner 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.

Customer self-repair warranty service
HP products are designed with many Customer Self Repair (CSR) parts to minimize repair time and allow for greater flexibility in performing defective parts replacement. If during the diagnosis period, HP identifies that the repair can be accomplished by the use of a CSR part, HP will ship that part directly to you for replacement.
There are two categories of CSR parts: 1) Parts for which customer self repair is mandatory. If you request HP to replace these parts, you will be charged for the travel and labor costs of this service. 2) Parts for which customer self repair is optional. These parts are also designed for Customer Self Repair. If, however, you require that HP replace them for you, this may be done at no additional charge under the type of warranty service designated for your product.
Based on availability and where geography permits, CSR parts will be shipped for next business day delivery.
Same-day or four-hour delivery may be offered at an additional charge where geography permits. If assistance is required, you can call the HP Technical Support Center and a technician will help you over the phone. HP specifies in the materials shipped with a replacement CSR part whether a defective part must be returned to HP. In cases where it is required to return the defective part to HP, you must ship the defective part back to HP within a defined period of time, normally five (5) business days. The defective part must be returned with the associated documentation in the provided shipping material. Failure to return the defective part may result in HP billing you for the replacement. With a customer self repair, HP will pay all shipping and part return costs and determine the courier/carrier to be used.

Environmental product stewardship program
Protecting the environment
Hewlett-Packard Company is committed to providing quality products in an environmentally sound manner.
This product has been designed with several attributes to minimize impacts on our environment.
Ozone production
This product generates no appreciable ozone gas (O
3
).
Power consumption
Power usage drops significantly while in Sleep or Auto-Off mode, which saves natural resources and saves money without affecting the high performance of this product. Hewlett-Packard printing and imaging equipment marked with the ENERGY STAR qualified imaging products:
® logo is qualified to the U.S. Environmental Protection Agency's
ENERGY STAR specifications for imaging equipment. The following mark will appear on ENERGY STAR
Additional ENERGY STAR qualified imaging product model information is listed at: www.hp.com/go/energystar
Toner consumption
EconoMode uses less toner, which might extend the life of the toner cartridge. HP does not recommend the full-time use of EconoMode. If EconoMode is used full-time, the toner supply might outlast the mechanical parts in the toner cartridge. If print quality begins to degrade and is no longer acceptable, consider replacing the toner cartridge.
Paper use
This product’s manual duplex feature (two-sided printing) and N-up printing (multiple pages printed on one page) capability can reduce paper usage and the resulting demands on natural resources.
Plastics
Plastic parts over 25 grams are marked according to international standards that enhance the ability to identify plastics for recycling purposes at the end of the product’s life.
