Toner cartridge information

The toner cartridge is designed to simplify replacement of the major consumable parts. The toner cartridge contains the printing mechanism and a supply of toner.

At 5% page coverage, a toner cartridge will print approximately 2,500 pages. However, a toner cartridge should print more pages if it regularly prints pages with less coverage, such as short memos. The cartridge might print fewer pages if heavy or bold print is used.

Note For best results, always use a toner cartridg e before the expiration date

stamped on the toner cartridge box.

Refilled toner cartridges

While Hewlett-Packard does not prohibit the use of refilled toner cartridges during the warranty period or while the printer is under a maintenance contract, it is not recommended for the following reasons:

l Repairs resulting from the use of refilled toner cartridges are not

covered under Hewlett-Packard warranty or maintenance contracts.

l Hewlett-Packard has no control or process to ensure that a

refilled toner cartridge functions at the high level of reliability of a new HP LaserJet toner cartridge. Hewlett-Packard also cannot predict the long term reliability effect on the printer from using different toner formulations found in refilled cartridges.

l The print quality of HP LaserJet toner cartridges influences the

customer’s perception of the printer. Hewlett-Packard has no control over the actual print quality of a refilled toner cartridge.

Recycling toner cartridges

In order to reduce waste, Hewlett-Packard offers a recycling program. Cartridge components that do not wear out are r ecycled. Plastics and other materials are recycled. Hewlet t-Packard pays the shipping costs from the user to the recycling plant. To join this recycling effort, follow the instructions inside the toner cartridge box.

Printer and parts

Design for recycling has been incorporated into this printer and its accessories. The number of materials has been kept to a minimum while ensuring proper functionality and high product reliability. Dissimilar materials have been designed to separate easily. Fasteners and other connections are easy to locate, access, and remove with common tools. High-priority parts h ave been designed to be accessed quickly for efficient disassembly and repair. Plastic parts have been primarily designed in two colors to enhance recycling options. A few small parts are colored specifically to highlight customer access points. The plastics used in the printer housing and chassis are technically recyclable.

Selecting media

Selecting media to print

You can use paper with up to 100% recycled fiber content if it meets HP’s specifications. To order HP paper or the Print Media Guide for HP LaserJet printers, see “Ordering parts and supplies ” on page 200.

Highly textured stock might not print evenly. Very glossy papers might jam or repel toner. Multipart forms can wrinkle or get jammed in the product. And paper in poor condition, such as paper with tears, wrinkles, or bent edges, can jam.

Avoid envelopes that have a very slick finish, ones that have self-stick adhesives, or those with clasps or windows. Also avoid envelopes with thick, irregular, or curled edges, or areas that are wrinkled, torn, or otherwise damaged.

Use a sturdy envelope of approximately 16- to 27-pound (7.25 to

12.25 kg) weight. Use tightly constructed envelopes and make sure the folds are sharply creased.

The paper input tray can hold up to 125 sheets of 20 lb (75 g/m media. The single-sheet input tray is designed for one sheet. Both can be adjusted to hold media measuring from 3 by 5 inches (76.2 by 127 mm) to 8.5 by 14 inches (216 by 356 mm). This includes, but is not limited to, the following paper and envelope sizes:

Selecting media to fax, copy, or scan

The product can scan items of various sizes, from 2 by 3.5 inches (51 by 89 mm) (the size of a business card) to 8.5 by 14 inches (215 by 356 mm). The product can fax and copy items ranging from 2 by 3.5 inches (51 by 89 mm) to 8.5 by 35 inches (215 by 889 mm).

The product accepts bond paper, onionskin paper, newspaper pages, magazine pages, recycled paper, transparencies, and photographs, and accepts other items in carrier sheets. Coarse papers scan more easily than smooth items. Slick papers can go through the product, although they can be more difficult to feed through. For best results, feed slick sheets one at a time, and set the special media lever correctly.

Perform the following actions to minimize the possibility of jams:

l Remove self-stick notes. l Remove staples and paper clips. l Straighten any curls or wrinkles in documents before put ting them

into the document feeder tray.

l Do not insert any document with glue, correction fluid, or wet ink

on it.

l Do not insert gum-backed paper or labels. l Place documents with tears, perforations, or punch ho les in a

carrier sheet, which you can buy or make. (See “To load special items” on page 46.)

l Avoid multiple-copy forms.

If your document is a transparency, is in a carrier sheet, or is not on regular-weight paper, use the directions for “To load special items” on page 46.

), see "To load normal media"

To load normal media

1 Adjust the guides in the document

feeder tray to fit the size of the item you are loading.

2 Place up to 30 pages leading edge

first, face down, into the document feeder tray.

To load special items

When loading items to be faxed, copied, or scanned, you need to protect small, fragile, lightweight (less than 12 lb. or 46

g/m

), or irregularly sized items such as receipts, newspaper clippings, photographs, and old or worn documents.

1 Do one of the following:

l Place the item in a carrier sheet. You

can buy a carrier sheet, or you can make one by taping a transparency and piece of paper together along one of the short sides. Insert the item to be faxed, copied, or scanned into the carrier, and insert the carrier into the document feeder t ray, tap ed edge first.

- Or -

l Using clear tape, tape the leading

and trailing edges of the item to a sheet of letter- or A4-size paper. If the item is not square or rectangular, tape all edges of the item to the paper.

- Or -

l If you have use of a full-size copier,

copy the item first and then send the copy through the scanner.

2 Adjust the guides in the document

feeder tray to fit the size of the item you are loading.

3 Locate the special media lever (see

figure 3 on page 21) on the t op edge of the control panel and move it to the right. The special media lever opens the document feeder mechanism, allowing you to feed thick items, one at a time, into the document scanner.

Note

Move the special media lever back to the left after special items have been fed. A stack of regular pages sent with the lever to the right feed in multiples and cause jams.

CAUTION

Do not move the lever after the product has begun sending the page.

4 Load only one shee t at a tim e,

leading edge first, face down, into the document feeder tray.

Note

If you are loading a business card, load it long edge first.

Loading media to be printed

Loading the paper input tray

You can load up to 125 sheets of 20 lb ( 75 g/m2) media into the paper input tray or feed one sheet at a time into the single-sheet input tray.

Note Insert all media vertically (portrait orientation) into the paper input tray

or single-sheet input tray. If you want to print horizontally (landscape orientation), make this selection through your software. Do not pr int on paper smaller than 3 by 5 inches (76.2 by 127 mm).

To load the paper input tray

The product prints, copies, and prints received faxes using media from the paper input tray (or the single-sheet input tray).

1 Adjust the guides on the paper input

tray to fit the size of media you are loading.

2 Insert up to 125 sheets of paper into

the paper input tray. Be careful not to overfill the bin.

Note

When adding media to an existing stack in the paper input tray, always remove the existing media and realign it with the new media before loading to reduce multiple feeds or jams.

Note

If you have loaded special media, make sure to choose the lower paper output path. See “To select the output path” on page 50

3 Readjust the guides to center the

stack.

48 Chapter 2 - Installation and operation EN

Page 51

Using the single-sheet input tray

Using the single-sheet input tray, you can print one sheet of media at a time without using the paper input tray. The product takes media loaded in the single-sheet input tray before it takes from the paper input tray.

Note The single-sheet input tray is helpful when the firs t page of your job is

different from the rest. For e xample, you might want the first page of your print job on letterhead, or you may want to prin t an envelope firs t.

To print using the single-sheet input tray

1 Adjust the guides to the approximate

size of the sheet you are using.

2 Insert one sheet of media into the

single-sheet input tray. If loading special media or letterhead, insert

media top first, facing forward.

3 Readjust the guides to center the

sheet.

Note

If you have loaded special media, make sure to choose the lower paper output path. See “To select the output path” on page 50.

EN Loading media 49

Page 52

Selecting the output path

Use this procedure to determine if printed pages should come out of the paper output bin or the front paper output slot. Choose the front paper output slot if you are printing on special media, such as 28 lb (100 g/m or labels. This prevents wrinkling and paper curl.

) or heavier weight paper, envelopes, transpar encies,

To select the output path

l To use the paper output bin, make

sure that the front paper path door is closed.

- Or -

l To use the front paper output slot,

open the front paper path door. All printed media coming out of the f ront paper output slot will be in reverse order. If you open the front paper path door and media does not go through the front paper output slo t, make sure the front paper path door is all the way open.

Note

Keep the area in front of the front paper output slot clear so that media can easily exit the slot.

Basic functions

This chapter presents a functional ove rview of th e HP La ser Je t 32 00 product’s processes. The following systems are discussed:

l optical system (document scanner) l formatter l printer functions

• ECU (engine controller unit) system/power system

• image formation system

• paper-feed system (printer) and document-feed system

(document scanner)

The HP LaserJet 3200 product consists of the printer and the document scanner. Operation sequences of the pr inter are con trolled by the ECU. Operation sequences of the document scanner are controlled by the formatter.

Figure 7. Basic configuration

62 Chapter 4 - Operational overview EN

Page 65

Optical system

The document scanner system consists of the optical system and document pickup and feed systems.

The optical system, also known as the contact image sensor, contains the following:

l light-emitting diode (LED) array l contact glass l rod lens array l sensor array

The light source has three LEDs (red, green, and blue) and is controlled by the formatter. Light reflected from documents passes through the rod lens array and focuses on the sensor array.

The sensor array consists of 5,160 photo transistors: 1 5 driver circuits amplify the light reception output in units of 344 phototransisto rs. The image data is converted and sent from the driv er circu i ts to th e formatter.

The document pickup and feed systems contain a pickup roller, feed roller, and delivery roller, all of which are driven by the document scanner motor (M101).

EN Optical system 63

Page 66

The following figure shows the document scanner path.

64 Chapter 4 - Operational overview EN

Page 67

Formatter system

The formatter is responsible for the following:

l controlling the document scanner l formatting and controlling faxes l formatting and controlling copies l receiving and processing print data from the printer interface l monitoring the control panel and relaying printer status

information

l developing and coordinating data placement and ti ming with the

print engine

l communicating with the host computer through the bidirectional

interface The formatter receives print data from the bidirectional Extended

Capabilities Port (ECP) mode interface or 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 MCF5202 custom microprocessor operating at 35 megahertz (MHz).

RAM

l One bank of Non-Volatile RAM (NVRAM) stores parameter s l DRAM provides temporary storage of copy, scan, and print data

EN Formatter system 65

Page 68

Parallel interface or Universal Serial Bus (USB) interface

The formatter receives incoming data through it s bidirectional ECP or USB interface. This interface provides high speed and two-way communication between the printer and the host, allowing the user to change printer settings and monitor printer status from the host computer.

Control panel

l two front panel status lights l control panel keyboard l control panel display

Draft mode

Depending on which printer driver is used, selecting draft or EconoMode from the printer driver allows the HP LaserJet 3200 product to use approximately 50% less toner, extending the life of the toner cartridge.

MEt

The Hewlett-Packard Memory Enhancement technology effectively doubles the standard memory through a variet y of font and datacompression methods.

Enhanced I/O

The Enhanced I/O feature allows printer memory to be used for storing data received from the host computer. When Enha nced I/ O is enabled, you can send more data to the print e r in sh or ter amo unt s of time, which allows you to return to your application sooner. Enhan ced I/O has the following options:

l Auto—allows the printer to use Enhanced I/O memory allocation

to increase the speed of data transfer from the host computer to

the printer, if necessary.

l Off—uses the minimum amount of printer memory for storing

data sent from the host computer.

66 Chapter 4 - Operational overview EN

Page 69

Page Protect

Page complexity (ruling lines, complex graphics, or dense te xt) can exceed the printer’s ability to create the page image fast enough to keep pace with the image formation process. If Page Protect is disabled and a page is too complex, the page might print in parts (for example, the top half on one page and the bottom half on the next page). Some print-data loss is likely in these instances, and the printer will display an error message.

Page Protect allows the formatter to create the en tire page image in page buffer memory before physically moving the paper through the printer. This process ensures that the entire page will be printed. The default setting is Auto.

PJL Overview

Printer Job Language (PJL) is an integral part of configuration, in addition to the standard Printer Command Language (PCL). With standard ECP cabling, PJL allows the printer to perform functions such as:

l Two-way communication with the host computer through a

bidirectional parallel or USB connection. The printer can tell the

host such things as the control panel status.

l Isolation of print envir onment settings from on e print job to the

next. For example, if a print job is sent to t he print er in lan dscape

mode, the subsequent print jobs print in landscape only if they

are formatted for landscape printing.

Paper motion monitoring and control (printing)

The ECU controls paper motion in the printer by continuously monitoring the various paper sensors and coordina ting the timing with the other print processes.

For a detailed explanation of paper movement and the interaction of photosensors and solenoid with the paper movement process, see “Printer paper feed system” on page 77.

Motor

The motor is controlled by the ECU. The motor provides all of the printer's paper movement.

Printer laser/scanner drive

The ECU sends signals to the laser/scanner assembly to modulate the laser diode “on” and “off” and to drive the laser/scanner motor.

Power system on ECU

The AC, DC, and high-voltage power su pply circuit s ar e all contai ned within the ECU.

AC power distribution

The AC power circuitry supplies AC voltage whenever the power cord is connected to the AC power source. AC voltage is distr ibut ed t o the DC power supply circuitry and to the AC driver circuitry, which controls AC voltage to the fusing assembly's heating element.

DC power distribution

The DC power distribution circuitry, located on the ECU, distributes +3.3 Vdc, +5 Vdc, and +24 Vdc as follows:

l +3.3 Vdc: Formatter

Laser/beam detect circuitry ECU

l +5 Vdc: Formatter

Photosensors ECU Laser/beam detect circuitry

l +24 Vdc: Motor

Laser scanner motor Document scanner motor Solenoid Formatter

l +24VAdc: High voltage power supply

Overcurrent/overvoltage

There are two overvoltage devices in this printer:

l Fuse F101 provides overcurrent protection for the fusing system

circuitry. Checking or replacing the fuse requires the removal of

the ECU. Fuse F102 (found only on 110V units) provides

overcurrent protection to the prin te r DC powe r su pp ly ci rcu itr y.

l In addition, the +24Vdc, +3.3 Vdc, and +5Vdc power circuitry

contains an overcurrent protection circuit that automatically shuts

off the output voltage when an overcurrent condition occurs as a

result of a short or an abnormal voltage on the load side.

72 Chapter 4 - Operational overview EN

Page 75

High-voltage power distribution

The high-voltage power supply PCA applies an overlap of DC and AC voltage to the primary charging roller and 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 acco rding to t he pr int densit y setting.

High voltage is disabled when the printer door is open.

EN Printer functions 73

Page 76

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 inde pen dently an d must be coordinated with the other printer processes. Image formation consists of seven processes:

Figure 13. Image formation block diagram

Toner cartridge

As the heart of the image formation system, the toner cartridge houses the cleaning, conditioning, and developing steps of the process. The toner cartridge contains the photosensitive primary charging roller, developing station, toner cavity, and cleaning station. Including these components (which wear, degrade, or are consumed) in the replaceable toner cartridge eliminates the need for a service call when replacement is required. The special photosensitive properties of the drum allow an image to be formed on the drum surface and then transferred to paper.

CAUTION The printer's toner cartridge does not include a light-blocking shutter.

Be careful to avoid exposing the drum to light, which can permanen tly damage the drum. Protect the toner cartridge when ever removing it from the printer.

74 Chapter 4 - Operational overview EN

Page 77

Breakdown of the six image formation processes

Step 1 Conditioning stage (primary charging). This process consists

of applying a uniform negative charge to the surface of the drum with the primary charging roller located in the toner 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, a negative DC bias is applied by the charging roller to create a uniform negative potential on the drum surface. The amount of DC voltage is modified by the print density setting.

Step 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 toner 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 is sweeping the entire length of the drum and the drum is rotating, 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 used to synchronize the output of the next scan line of data.

Step 3 Developing stage. At this stage of the 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, grounded) areas of the drum, and repelled from the negatively charged (unexposed) areas.

Step 4 Transfer stage. During the transferring process, the toner

image on the drum surface is transferred to the paper. A positive charge applied to the back of the paper by the transfer roller causes the negatively charged toner on the drum surface to be attracted to the paper. After separation, the drum is cleaned and conditioned for the next image.

EN Printer functions 75

Page 78

Step 5 Separation stage. During the separating process, the paper

separates from the drum. To stabilize the feed system and prevent dropouts on the printed image at low temperature and humidity, the charge on the back of the paper is reduced by the static charge eliminator.

Step 6 Fixing stage. During the fixing process, the toner is fused into

the paper by heat and pressure to produce a permanent image. The paper passes between a heated fusing element and a soft pressure roller. This melts the toner and presses it into the paper.

Step 7 Drum cleaning stage. The cleaning blade is in contact with

the surface of the drum at all times. As the drum rotates during printing, excess toner is wiped off and stored in the waste toner receptacle.

76 Chapter 4 - Operational overview EN

Page 79

Printer paper feed system

The paper input tray and the single-sheet input tray merge into one, main input area. Paper placed in either of these areas enables the paper-out sensor (PS001), which informs the ECU that paper is present. The following steps occur when the printer receive s a print job:

Step 1 The ECU enables the laser/scanner assembly and the motor.

Paper motion begins when the ECU energizes the solenoid (SL001).

Step 2 The paper pickup roller rotates once. The paper kick plate

pushes the paper against the pickup roller.

Step 3 The pickup roller grabs the top sheet and advances it to the

feed assembly drive rollers. To ensure that only one sheet is fed, a main separation pad and two subpads hold the remainder of the stack in place.

Step 4 The feed assembly drive rollers advance the paper to the

paper top photosensor (PS002). This sensor informs the ECU of the exact location of the paper's leading edge, so that the image being written on the photosensitive drum can be precisely positioned on the page.

Step 5 The feed assembly drive rollers then advance the paper to

the transfer area where the toner image on the photosensitive drum is transferred to paper.

Step 6 After the image is transferred, the paper enters the fusing

assembly where heat from the fuser and pressure from the pressure roller permanently bond the toner image to paper. The paper exit sensor (PS201) determines that paper has successfully moved out of the fusing area.

Step 7 The fusing assembly exit rollers deliver paper to either the

paper output bin or the front paper output slot, depending upon the position of the front paper path door.

Jam detection

The paper-out sensor (PS001) detects the presence of media in either the single-sheet input tray or the paper input tray. The paper top sensor (PS002) and the paper delivery sensor (PS201) detect media moving through the HP LaserJet 3200 product. If a jam is detected, the ECU immediately stops the printing process and displays a jam message on the control panel.

A jam can be detected under any of the following conditions:

l Pickup delay jam. Media does not reach th e pa pe r to p se nso r

after the pickup solenoid (SL001) has be en turned on three times

(the initial pickup attempt plus two retries) within 7.9 seconds.

l Pickup stationary jam. The paper top sensor does not detect the

trailing edge of media within 7.8 seconds of detecting the leading

edge.

l Delivery-delay jam. The paper delivery sensor does not detect

the leading edge of media within 3.2 seconds after the paper top

sensor detects the leading edge.

l Wrapping jam. The paper delivery sensor does not detect the

trailing edge of media within 2.4 seconds after the paper top

sensor detects the trailing edge.

l Delivery-stationary jam. The paper delivery sensor detects med ia

for three seconds after the paper top sensor detects the trailing

edge of the media.

l Initial residual-paper jam. The paper delivery sens or or the paper

top sensor detect media in the initial rotation period.

5 Paper-out sensor (PS001) senses whether or not media is loaded

in the paper input tray. Paper must be loaded before printing can

resume. 6 Document sensor (PS1) detects the presence of a document in

the document feeder. 7 Document-top sensor detects the leading edge of a document in

the document path.

8 Contact image sensor. 9 Paper-delivery sensor (PS201) senses when paper has

successfully moved out of the fusing area.

Basic sequence of operation (formatter-to-printer)

The formatter and the ECU share information during printer operation. The ECU-to-formatter connector (J201) forms a link that operates as a serial data bus. This allows printer status, command information, and dot-image data to be passe d between the two. The following events take place during normal printer oper ation:

Period Purpose Remarks

WAIT From the power-ON until the end of the main motor initial rotation.

STBY (Standby) From the end of the WAIT period or the LSTR period until the pickup command is input from the formatter. Or, from the end of the LSTR period until power-OFF.

INTR (Initial Rotation Period) After the pickup command has been input from the formatter until the paper reaches the paper top sensor.

PRINT (Print) From the end of the initial rotation until the primary voltage goes OFF.

LSTR (Last Rotation Period) After the primary voltage goes OFF until the main motor stops rotating.

To clear the drum surface of potential and to clean the transfer charging roller.

To keep the printer ready to print.

To stabilize the photosensitive drum sensitivity in preparation for printing. Also to clean the transfer charging roller.

To form images on the photosensitive drum based on the VIDEO signals (/VDO, VDO) input from the formatter and to transfer the toner image onto the paper.

To delivery the last page. Also to clean the transfer charging roller.

Detects whether or not the cartridge is installed.

When the pickup command is input from the formatter, the printer enters the INTR period immediately after the end of the LSTR period.
