Safety information
Toner safety
Handling and storage
WARNING! Keep toner cartridges and toner particles away from excessive heat, sparks, and open flames.
If toner is spilled, avoid breathing in toner particles. Inhalation of toner particles causes respiratory
tract irritation. Vacuum or sweep the material into a bag or other sealed container. A vacuum
specifically designed for cleaning toner can be used if it is capab le of filtering fine particles (5 microns
in diameter).
WARNING! Do not vacuum toner using a con ventional vacuum. Toner particles used in this product might be too
fine for effective vacuuming and could result in damage to a conventional vacuum.
Dispose of waste toner in accordance with local requirements. Do not discharge toner particles in
drains.
First aid measures
l Ingestion. If toner is ingested, rinse mouth out thoroughly with water and drink several glasses
of water. Get medical attention if symptoms persist.
l Inhalation. If toner particles are inhaled, move to fresh air immediately. If symptoms occur,
consult a physician.
l Eye contact. If toner comes in contact with the e y es, immediately flush with p lenty of wat er f or at
least 15 minutes. If irritation persists, consult a physician.
l Skin contact. If toner spills on skin, remove as much toner as possible with a dry tissue, and
then wash with cold water.
Clothing contact
Note Toner can stain clothing. Hot water or heat (from a clothes dryer) can cause toner to melt and
permanently fuse to clothing.
Clothing is best cleaned by removing as much toner as possible with a dry tissue, and then washing
with cold water. Air-dry clothing.

Laser safety
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration
has implemented regulations for laser product s manufactured since August 1, 1976. Compliance is
mandatory for products marketed in the United States. The printer is certified as a Class 1 laser
product under the U .S. Department of Health and Human Services (DHHS) Radiation Performance
Standard according to the Radiation Control for Health and Safety Act of 1968.
Because radiation emitted inside the printer is completely confined within protective housings and
external cover s, the laser beam cannot escape during any phase of normal user operation.
WARNING! Using controls, making adjustments, bypassing saf ety swit ches, or performing procedures other than
those specified in this service manual can result in exposure to hazardous radiation.
LED safety
The infrared port on the control panel of this printer is classified as a Class 1 LED (light emitting
diode) device according to International Standard IEC 60825-1 (EN 60825-1). This device is not
considered harmful, but the following precautions are recommended.
l Avoid direct eye exposure to the infrared LED beam.
l Be aware that the beam is invisible light and cannot be seen.
l Do not attempt to view the infrared LED beam with any type of optical device.

Service approach
Bench repair warranty
The warranty for this product is “return to bench” for a period of one year from t he date of purchase.
This means that customers needing warranty repair must return their printer to an HP repair center
or an Authorized Service Provider (ASP). See “Reseller sales and service support” on page 17.
HP Express Exchange
Through Customer Care Centers In the United States and Canada, customers have an option to
initiate Express Exchange. Under this option, customers can have a factory-refurbished printer sent
to them within 24 hours.
1 The customer contacts the local HP Customer Care Center listed in the product documentation.
A technician troubleshoots the situat ion and determines whether the printer has actually failed. If
so, the technician refers the customer to the HP Service Center.
2 A representative from the service center requests product and customer information. In some
regions, collateral might also be requested.
3 Hewlett-Packard Company ships a refurbished replacement unit to arrive the next day.
(Geographic distance might prevent next-day shipping.)
4 The customer sends the defective printer to Hewlett-Packard at HP's expense.
Customers with onsite support service provided by HP should work directly with the local Customer
Care Center instead of following the steps outlined here.
Exchanged units carry the remainder of the original unit’s warranty or a 90-day warranty, whichever is
greater. The faster turnaround from HP Express Exchange minimizes downtime over traditional
service programs that require the user to ship the f ailed unit to th e manuf acturer an d then wait f or it to
be repaired and returned. Because HP pays the shipping charges, the user incurs no hidden costs
for the service.
Note For warr anty information and requirements, please see the user guide.
Ordering information

Media specifications
General media specifications
The HP LaserJet 2200 series printers accept a variety of media, such as cut-sheet paper (including
up to 100 percent recycled-fiber-co nt en t pa pe r) , envelopes, labels, transparencies, and custom-size
paper. Properties such as weight, composition, grain, and moisture content are important factors
affecting printer performance and output quality. Media that does not meet the guidelines outlined in
this manual can cause the following problems:
l poor print quality
l increased jams
l premature wear on the printer, requiring repair
Note Some print media might meet all of the guidelines in this manual and still not pro duce satisfactory
results. This might be the result of improper handling, unacceptable temperature and humidity levels,
or other variables over which Hewlett-Packard has no control.
CAUTION Using print media that does not meet HP specifications might cause prob lems fo r the printer, re quiring
repair. This repair is not covered by the Hewlett-Packard warranty or service agreements.
Note Before purchasing large quant ities of paper, make sure the paper meets the requirements specified
in this service manual and in the HP LaserJet Printer Family Print Media Guide. See “Supplemental
documentation” on page 16 Always test print media before buying large quantities. For more
information see the HP LaserJet Printer Family Print Media Guide at http://www.hp.com/cposupport/
printers/manuals/
28 Chapter 2 Operating requirements C7058-90936
Guidelines for selecting paper
For best results , use conventional 80 g/m2 (20 lb) paper. Make sure the paper is of good quality, and
free of cuts, nick s, tears, spots, loose particles, dust, wrinkles, voids , and curled or bent edges.
If you are unsure what type of paper you are loading (such as bond or recycled), check the label on
the package of paper.
The following problems with paper can cause print quality deviations, jamming, or even damage to
the printer.

Envelope specifications
Envelope construction is critical. Envelope fold lines can vary considerably, not only between
manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes
depends upon the quality of the envelopes. When selecting envelopes, consider the following
components:
l Weight: The weight of the envelope paper should not exceed 105 g/m
occur.
l Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 in) curl, and
should not contain air.
l Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged.
l Temperature: Envelopes should be compatible with the heat and pressure of the printer.
l Size: Envelopes must be within the following size ranges: minimum of 76 by 127 mm (3 by 5 in)
and maximum of 216 by 356 mm (8.5 by 14 in).
Note Use only tray 1 to print en v elo pes . Send e n v elope s stra ight th rough the printer, entering at tray 1 and
exiting from the rear output bin
CAUTION Jams might occur when using any media with a length less than 178 mm (7 in). This can be caused
by paper that has been aff ected by environmental condition s. See "Evaluate environment al conditions"
in chapter 7.
Envelopes might meet the general specifications listed in table 14 and still not print satisfactorily
because of the printing environment or other variables over which HP has no control.

Table 14. Envelope specifications
Description Specification
Paper Paper used for en velope construction must meet the paper specifications listed in
this manual and the HP LaserJet Printer Family Print Media Guide (except for
those listed below).
Basis weight 60 to 100 g/m2 (16 to 27 lb), single thickness. Jamming might result if 100
(27 lb) weight is exceeded. See “Moisture-content field test” on page 39
Finish Avoid using envelopes with adhesive exposed to the printer. Envelopes must be
folded accurately so that there are no more than two thicknesses of paper
anywhere along the leading edge. All folds must be well scored and sharply
creased, and construction must be tight (not baggy). Avoid using envelopes that
are stuck together with excess seam gum. See “Furnish (fiber composition) field
test” on page 40
Fusing compatibility All inks, adhesives, and other materials used in the envelope must be compatible
with the heat and pressure of the fusing process. Materials must not discolor,
melt, offset materials, or release hazardous emissions when heated to
200 degrees C (392 degrees F) for 0.1 second. See “Fusing-compatibility field
test” on page 40
Curl (Pre-printed) Envelopes must lie flat, with no more than 5 mm (0.2 in) curl across the entire
surface. See “Curl field test” on page 40

C7058-90936 Media specifications 33
Envelopes with adhesive strips or flaps
Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use
adhesives compatible with the heat and pressure in the printer. The extra flaps and strips might
cause wrinkling, creasing, or jams and can even damage the fuser.
Envelope storage
Proper storage of en v elopes contributes to good print quality. Envelopes should be stored flat. If air is
trapped in an envelope, creating an air bubble, then the envelope might wrinkle during printing.
Envelopes with double side seams
Double side-seam construction has v ertical seams at both ends of the en velope rather than diagonal
seams. This style might be more likely to wrinkle. Be sure the seam extends all the w a y to the corner
of the envelope as illustrated below.
Figure 13. Double side seam
Envelope margins
The following gives typical address margins for a commercial #10 or DL envelope.

Note For the best print quality, position margins no closer than 15 mm (0.6 in) from the edges of the
envelope.
Avoid printing over the area where the envelope seams meet.
34 Chapter 2 Operating requirements C7058-90936
Label specifications
When selecting labels, consider the quality of each component:
l Adhesives: The adhesive material should be stab le at 200 degrees C (392 degrees F), which is
the printer’s fusing temperature.
l Arrangement: Only use labels with no exposed backing between them. Labels can peel off
sheets with spaces between the labels, causing jams.
l Curl: Prior to printing, labels must lie flat with no more than 13 mm (.5 in) of curl in any direction.
l Condition: Do not use labels with wrinkles, bubbles, or other indications of separation.
Note Use only tray 1 to print labels. Send labels straight through the printer, entering at tray 1 and exiting
from the rear output bin
CAUTION To avoid damaging the printer, use only labels recommended for laser printers.
Never print on the same sheet of labels more than once or print on a partial sheet of labels.

Storing print media
Ideally, the printing and media storage environment should be at or near room temperature, and not
too dry or too humid. Remember that paper is hygroscopic; it absorbs and loses moisture rapidly.
Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate, while
cold causes it to condense on the sheets. Heating systems and air conditioners remove most of the
humidity from a room. As a paper package is opened and used, it loses moisture, causing streaks
and smudging. Humid weather or water coolers can cause the humidity to increase in a room. As
paper is opened and used it absorbs any excess moisture, causing light print and dropouts. Also, as
paper loses and gains moisture it can distort. This can cause jams.
As a result, paper storage and handling are as important as the paper-making process itself. Paper
storage environmental conditions dir ectly affect the feed operation.
Users should not purchase more paper than can be easily used in a short time (about three months).
Paper stored for long periods might experience heat and moisture extremes, which can cause
damage. Planning is important to prevent damage to a large supply of paper.
Unopened paper in sealed reams can remain stable for several months before use. Opened
packages of paper ha v e more p otential f or en vironmental d amage, especially if the y ar e not wr apped
with a moisture-proof barrier.
36 Chapter 2 Operating requirements C7058-90936
The paper storage environment should be properly maintained to ensure optimum printer
performance. The required condition is 20 degrees to 24 degrees C (68 degrees to 75 degrees F),
with a relative humidity of 45 percent to 55 percent. The following guidelines should be helpful when
evaluating the papers storage environment:
l Paper should be stored at or near room temperature.
l The air should not be too dry or too humid (because of the hygroscopic properties of paper).
l The best way to store an opened ream of paper is to rewrap it tightly in its moisture-proof
wrapping. If the printer environment is subject to extremes, unwrap only the amount of paper to
be used during the day's operation to prevent unwanted moisture changes.
Shipping print media
When shipping print media through different environments, plastic-wrap all cartons on the shipping
pallet. When shipping media across bodies of w ater , wrap individ ual cartons as well. Pac kaging m ust
protect the media from physical damage.
Paper fillers
Additional chemicals and fillers are frequently added to paper during the manufacturing process.
These can affect the paper strength, pick resistance, printability, bulk, feel, and color.
An emulsion containing w ax, rosin, starch, or other non- water so luble m aterials is added to t he paper
pulp to help control penetration by water and other liquids. Dyes are added and the paper might be
bleached. Bleaching is a multistep process using such chem icals as hydrogen peroxide and chlorine
dioxide. This transforms the paper from its original brownish state to the desired color.
Finely ground fillers, such as clay, talc, and calcium carbonate, might be added to even out the
“peaks and valleys” that occur in the paper mixture, and serve as brighteners. Ov er time, these fillers
can build up on internal assemblies of the printer such as rollers or the toner cartridge. This buildup
can eventually cause jams and print defects. To minimize this risk, periodically clean the printer
according to procedures. See "Cleaning the printer and accessories" in chapter 4.
Testing media specifications
The following tests describe ways to qualify the media with respect to the specifications listed in this
manual and the HP LaserJet Printer F amily Print Media Guide. See “T ools and suppliers” on page 41
for help obtaining tools needed to perform these tests.
Basis-weight field test
The basis weight should be indicated on the ream label. If th e label is not a v ailab le, a simple field test
can identify the basis weight of paper. The basis weight of paper is equal to the weight of 2000
sheets of paper, or four full reams. Weigh a full ream on a postal scale and then multiply that weight
by four. Or, weig h 10 sheets of paper, divide that weight by 10, multiply by 2000, and then divide by
16.
Table 17. Determining basis weight of paper
Amount Formula
4 reams weight = basis weight
1 ream weight x 4 = basis weight
10 sheets (weight divided by 10) x 2000 and then divided by 16 = basis weight
C7058-90936 Media specifications 37
Note Example:
10 sheets weigh 1.6 ounces
0.16 ounce x 2000 = 320 ounces
320 ounce ÷ 16 ounce/lb = 20lb paper
Paper weight equivalence table
Use this table to determine appro ximate equivalent points in weight specifications other than U.S.
bond weight. For example, to determine the equivalent of 20 lb U.S. bond-weight paper in U.S.
cover-weight p aper , lo cate the bond w eight (in ro w 3, second column) and sca n across the row to the
cover weight ( in the fourth column). The equivalent is 28 lb media. Shaded areas indicate a standard
weight for that grade.

Note The U.S. postcard measurements are approximate. Use for reference only.
Metric Sizes
For metric-size paper (A4), use the following method to determine basis weight.
Take 16 sheets of A4 paper and weigh them. One square meter of paper contains approximately 16
A4 size sheets. Compare this weight to t he appropriate weight in the “Paper weight equivalence
table” on page 2-38.
38 Chapter 2 Operating requirements C7058-90936
Caliper field test
The specified caliper differs with the type of media used. See “Operating environment” on page 26
Caliper can be measured in the field using a micrometer.
CAUTION Never use the coarse-adjustment end of the micrometer when measuring for caliper. The coarse
adjustment will compress the paper fibers, resulting in an inaccurate reading. For e xample, if the fibers
are compressed, 6 mil paper could measure as little as 3 mils. Always use the fine ad jus tm en t to
measure caliper .
Using the fine adjustment, slide the micrometer along the edge of the paper and measure at one
end. To double-check the accuracy of the reading, always measure again at the opposite end of the
paper.
Paper-finish field test
Paper finish, or smoothness, can be accurately measured with a Sheffield meter. If this tool is not
available, use a new U.S. dollar bill as a benchmark for comparing paper texture. A dollar bill has a
finish of 350 Sheffields, which is 100 over specifications. If paper feels as rough as a dollar bill, it is
recommended that users do not continually use this paper in the printer.
Moisture-content field test
Specification: Use paper with 4 percent to 6 percent moisture content.
A ream or sheet of paper can be measured with a moisture meter. In general, only e valuate the
customer’s storage environment when trying to determine if excess moisture or dryness is the cause
of a problem with paper.
Grain field test
The grain direction is usually specified on the ream label (written out “long” or “short”). The paper
dimensions listed on the label also indicate grain direction. For example, short-grain letter-size paper
will read “11 by 8.5" and long-grain paper will read “8.5 by 11."
If the grain direction is not included on the ream label, it can be determined by a simple w et t est. Cut
a small square from the corner of a sheet of paper, wet it, and observe the manner in which it curls.
Envelopes should have a diagonal grain, which gives them the best stability. To determine this, cut a
square section from one corner of an envelope. Wet this section and observe the manner in which it
curls. Two opposite corners should curl toward each other.
Figure 14. Long, short, and diagonal grain curl
C7058-90936 Media specifications 39
Curl field test
To check for paper curl, place a single sheet of paper onto a flat surface and measure curl at the
greatest deflection, holding a ruler perpendicular to the fl at surface.
Figure 15. Measuring curl
Cut-edge condition field test
The condition of the cut edge can be easily observed with an eye loop. Under magnification, a good
edge will appear even. A poorly cut edge will show fraying, jagged edges, compressed fibers, and
other damage.
Furnish (fiber composition) field test
Use paper made from 100 percent chemical wood pulp and /or cotton fiber. Recycled paper made
with no more than 5 percent groundwood is also acceptable.
Read the ream label to determine the fiber composition of the paper. Paper is usually specified as
xerogra phic bond (suitable for copiers or laser printers) or cotton bond. Cotton bond paper of 25
percent, 50 percent, or 100 percent will be indicated on a watermark. If paper is less than 25 percent
cotton bond, the watermark will not indicate a percentage. A wood-pulp test kit can also be used to
test fiber composition.
Fusing-compatibility field test
Inspect the rollers for colored ink b uildu p from preprinted logos or let terhead, and for toner buildup or
spots. Inspect printed output for repetitive defects and smearing. If necessary, have users contact
the forms vendor to ensure the paper’s fusing compatibility with HP LaserJet printers.

Engine test
Performing an engine test
The engine test can be used to verify that the print engine is functioning correctly. The fo rmatter PCB
is completely bypassed during an engine test; there fore, this test is useful for isolating problems.
Because the engine test prints a full page of horizontal lines across the entire printable area , it is also
useful for checking registration.
To print an engine-test page, insert paper into tray 1 or tr a y 2, remove the EIO cover , and use a long,
nonconductive object to press the engine-test button (callout 1) shown in figure 21. A single page
prints.
Note The duplexer test will pull paper from tray 2, but paper must be present in tray 1.
To perform a duple xer test, insert paper into tray 1 and tr ay 2, remove the EIO co ver, and use a long,
nonconductive object to press the engine-test button shown in figure 21. A duplexed page prints.
WARNING! Do not use an electrically conductive object to press the engine-test button.
Do not insert any object into the opening next to the power cord socket. This is not the engine-test
button.

Service mode
In service mode the following can be performed:
l Print a service mode self test.
l Verify and set the page count. See “Setting the page count” on page 53.
l Set the cold reset default. See “Setting the cold reset default” on page 54.
l Set the demo page = true/f alse (u sed to r emove the demo page from the service mode self test).
l Set the diagnostic functions on or off (for software developers ’ use only).
Entering service mode
Use PJL commands to enter service mode and perform various service-mode configurations. See
table 21. Users must use the exact character and case specified for PCL printer commands. The
following are elements of a typical printer command:
escape character
(begins escape sequence)
parameterized character
value field
(contains both alpha and numeric characters)
termination character (uppercase)
group character
l escape character (begins escape sequence)
l parameterized character
l group character
l value field (contains both alpha and numeric characters)
l termination character (uppercase)
Escape sequences can be combined into one escape sequence string. There are three important
rules to follow when combining code:
1 The first two characters after the escape character (the parameterized and group characters)
must be the same in all of the commands to be combined.
2 When combining escape sequences, change the uppercase (termination) character in each
individual escape sequence to lowerca se.
3 The final character of the combined escape sequence must be uppercase.
Entering escape characters
Printer commands always begin with the escape character (EC). The following table shows how the
escape character can be entered from various DOS software applications

Service check points
Periodic replacem ent parts are the parts that should be inspected and if requir ed, replaced at r egular
intervals. F ailure of t hese parts can seriously affect th e printer’s perf ormance. The se parts should be
inspected during a regular service visit near the end of the part’s expected life and replaced if found
to be worn or damaged.
Periodic inspection of parts
The following parts should be inspected and, if required, repla ced after appro ximately 150,000 pages
of use:
l fuser assembly
l transfer roller
l separation pads (tray 1, tray 2, and tray 3)
l pickup rollers (tray 1, tray 2, and tray 3)
l output feed rollers (upper and lower)
l transport belts and rollers
See "Removal and replacement" in chapter 6 for procedures to remove and replace these parts.
See "Parts and diagrams" in chapter 8 for the part numbers.
Variables such as media, environment, and usage can cause premature wear of these parts. See
"Media specifications" in chapter 2 for information about suitable media, environment, and usage
conditions.
60 Chapter 4 Printer maintenance C7058-90936
Cleaning the printer and accessories
To maintain superior print quality and performance, use the following procedures to clean the printer
and the paper-handling accessories thoroughly every time you change the toner cartridge or
whenever print-quality problems occur.
General cleaning
WARNING! Before yo u begin these steps, turn the printer off and unplug all power cords to avoid shock hazard.
CAUTION Do not use ammonia-based cleaners on or around t he printer. While cleaning the printer, be careful
not to touch the transf er roller (located underneath the toner cartridge). Skin oils on the roller can cause
print-quality problems.
To prev ent da mage, do not expose the toner cartridge to light. Place a piece of paper ov er the top of
the toner cartridge to shield it while it is out of the printer.
l Clean the outside of the printer with a water-dampened cloth.
l Clean the inside of the printer with a dry, lint-free cloth:
• transfer roller
• tray 1, tray 2, and tr ay 3 pickup roller
• tray 1, tray 2, and tray 3 separation pad
• registration shutter
• transfer guide unit
• feed belt/feed guide unit
• fusing assembly entrance guide
Cleaning spilled toner
Defective to ner cartridges can develop leaks. After a jam has occurred, some toner might remain on
the rollers and guides inside the printer. The pages that print immediately after the jam can pick up
this toner.
Note To clean skin and clothing if toner spills, remove as much toner as possib le with dry tissue, then wash
with cold water. Hot water causes toner to permanently set into clothing.
Vacuum specifications
Do not vacuum the printer or any spilled toner using a conventional vacuum. Toner particles used in
this product might be too fine for effective vacuuming and could result in damage to conventional
vacuums.
A vacuum specifically designed f or cleaning ton er can be used if it is capa ble of filtering fine particles
(5 microns in diameter).
C7058-90936 Cleaning the printer and accessories 61
Internal cleaning
During the printing process, paper, toner, and dust particles can accumulate inside the printer. Over
time, this buildup can cause print quality problems such as toner specks or smearing. This printer
has an internal cleaning mode that can correct and prevent these types of problems.
WARNING! Before yo u begin these steps, turn the printer off and unplug all power cords to avoid shock hazard.
Step 1 Open the top cover.

Engine cleaning
Note For best results , use a transpa rency during this process . If a transparen cy is not av ailab le, use copi er-
grade paper; do not use bond or rough paper.
This process uses a transparency from tray 1 to remove dust and toner from the paper path. Use this
process if toner specks or dots appear on printouts. This process will produce a blank page which
should be discarded.

Toner cartridge information
Toner cartridges contain components that are sensitive to light, temperature, and humidity. Make
sure the user follows th e recommendations in this section to ensure the highest quality and longest
life of the toner cartridge.
Storage
The toner cartridge (C4096A) should not be removed from its pac kage unt il installation. The sh elf lif e
of a cartridge in an unopened package is approximately 2.5 years. The shelf life of a cartridge in an
opened package is appro x imately 6 months . The e xp iration date of the tone r cartridge is stamped on
the cartridge box.
If cartridges are stored, the storage environment should meet the conditions listed in th e following
table:
Table 24. Storing toner cartridges
Category Temperature Humidity
Operating 10 degrees to 32.5 degrees C
(50 degrees to 90.5 degrees F)
Storage -20 degrees to 40 degrees C
(-4 degrees to 104 degrees F)
35 percent to 85 percent RH
15 percent to 90 percent RH
If the toner cartridge must be removed from the printer, always store the cartridge:
l inside the protective bag in which it was originally packaged.
l in a dark cabinet, away from direct sunlight.
l correct side up and in a horizontal position (not standing on end).
l in a temperature listed in the table above.
l awa y from ammonia or other organic solvent fumes.
CAUTION Never shi p the printer wit h a to ner cartridge installed. Excessive vibration during shipping can cause
toner to leak, contaminating the printer.
Never e xpose the tone r cartridge to direct sunlight, or to room light. Bright light and direct sunlight can
permanently damage a toner cartridge.
Handling instructions
l Before installing a cartridge, evenly distribute the toner. See “Redistributing the toner” on page
67.
l Do not touch the surface of the photosensitive drum in the cartridge. Protect the drum from light
and contamination.
l Do not expose the cartridge to unnecessary vibrations or shock.
l Do not expose the photosensitive drum to strong light. Blurred areas on the page might indicate
that the drum has been exposed to light for too long. This causes permanent damage to the
photosensitive drum. Replace the cartridge.
l Never man ually rotate the drum, especially in th e re ve rse direction; it can cause internal damage
and toner spills.
C7058-90936 Toner cartridge information 65
Refilled toner cartridges
HP policy on non-HP toner cartridges
Hewlett-Packard Company cannot recommend use of new, refilled, or remanufactured, non-HP toner
cartridges. Because they are not HP products, HP cannot influence their design or control their
quality.
While Hewlett-Packard Company does not prohibit the use of refilled toner cartridges during the
warranty period or while under a maintenance contract, we do not recommend their use for the
following reasons:
l Hewlett-Packard has no ability to ensure that a refilled toner cartridge functions at the high level
or reliability of a new HP toner cartridge. Hewlett-Packard also cannot predict the long-term
effect of the different toner formulations found in refilled cartridges.
l Hewlett-Pac kard has no control ov er the print quality of a refilled toner cartridge. The print quality
of HP toner cartridges influences the customer’s perception of the printer.
l Repairs resulting from the use of refilled toner cartridges might not be covered under the HP
warranty or maintenance contract.
Recycling toner cartridges
In many countries, this product’s printing supplies (for example, toner cartridge) can be returned to
HP through the HP Printing Supplies Environmental Program. An easy-to-use take back component
of the program is available in more than 20 countries. Multilingual program information and
instructions are included in every new HP LaserJet toner cartridge and consumables box.
For more information, call (1) (800) 340-2445 (U.S. only) or visit the HP LaserJet supplies website:
U.S.: http://www.hp.com/ljsupplies/environment_main.html
Europe: http://www.hp.com/pays/eur_supplies/english/planetpartners
Customers outside the United States should call their local HP sales and service office for further
information regarding availability of the HP Printing Supplies Environmental Program.
Toner cartridge weights
The approximate weight of a toner cartridge when full and empty is as follows:
l Full: 1105 grams (39.07 ounce)
l Empty: 900 grams (31.77 ounce)
Toner cartridge life expectancy
The life of the toner cartridge depends on the amount of toner used in each print job. When printing
text at 5 percent coverage, an HP LaserJet 2200 toner cartridge lasts an average of 5,000 pages.
This assumes the default print density setting and that EconoMode is off (default settings).
Saving toner with EconoMode
Toner cartridge usage can be extended by usin g the printer’s EconoMode feature. EconoMode can
be turned on or off through the driver or HP LaserJet device configuration.
l EconoMode functions in portrait orientation only.
l EconoMode does not function at 1200 dpi.
l Some software applications might refer to EconoMode as “draft mode.”
66 Chapter 4 Printer maintenance C7058-90936
Redistributing the toner
When toner is low, faded or light areas might appear on a printed page. To temporarily improve print
quality, redistribute the toner. The cartridge will need to be replaced soon. Use the following
procedures to redistribute tone r.
WARNING! Avoid reaching too far into the printer. The adjacent fusing area can be hot.
CAUTION To prevent damage, do not expose the toner cartridge to light.
Step 1 Remove the toner cartridge from the printer.
Step 2 Rotate the toner cartridge and gently shake from side to side to redistribute the toner.

Basic operations
Power-on sequence
The sequence from power-on until the printer enters the standby (STBY) mode:
1 Power-on.
2 CPU initialization.
3 Formatter communication start.
4 Fusing heater drive.
5 Main motor, Reverse motor, and fan drive—Reads the paper-detecting status of each sensor in
the printer immediately before driving the main motor, and assesses a jam if residual media is
detected.
6 High-voltage control—Detects the cartridge presence and cleans the transf er charging roller
after the primary charging ac bias is turned on.
7 Residual paper check—After starting the main motor, detection of residual media in the printer
resumes. If residual media is detected, the printer assesses a jam or automat ically delivers the
residual media, according to the situation.
8 Failure or abnormality check—Detects door-open, fan-motor, and fuser-unit failures during the
other sequence periods.

Printer functionality and operation
Four major systems make up the HP LaserJet 2200 printer and allow it to operate. Each system
works independently to accomplish its task, but must be coordinated with the other systems to
successfully produce a printed page. Understanding these syst ems, their function, and how they
interact with each other is the key to troubleshooting any problem. See "Troubleshooting process" in
chapter 7 for detailed information about the HP LaserJet 2200.
The HP LaserJet 2200 printer’s four major systems are as follows:
l "Formatter system" page 74—Receives print data from the host, processes the image, and
transfers it to the engine control system. The formatter system also provides the interface
between the user and the printer (control panel).
l "Engine control system" page 77—Monitors and controls all of the printer’s mechanical and
electrical subsystems. It is the center of the printer’s operation.
l "Image formation system" page 80—Produces the actual physical image on the page.
l "Pickup/fe ed system" page 86—Mo ve s paper or other print media throug h the printer from one of
the selected input trays (tray 1, 2, or 3) to the selected output bin (top or rear).

Paper pickup and feed system
Formatter system
The formatter system is responsible for the following:
l receiving and processing data from the various printer interfaces
l monitoring control panel input and relaying printer status information (through the control panel
and the I/O)
l developing and coordinating data placement and timing with the print engine
l storing font infor mation and macros
l communicating with the host computer
The formatter receive s data fr om the I/O and con v erts it into a dot image . The formatter then sends a
print signal to the engine controller assembly. The engine controller assembly synchronizes the
image-formation system with the paper-feed system, and signals the formatter to send the printimage data. The formatter sends the print-image data (dots) in the form of a video signal and the
printing process begins.

Formatter hardware
The formatter system contains the following:
l CPU—Is a 133 Mhz Motorola Coldfire V4 with a 66 MHz bus.
l Read-only memory (ROM)—Stores the dot patte rns of internal character sets (f onts) in addition
to storing microprocessor control programs.
l Random-access memory (RAM)—Stores printing and font information received from the host
system, and can also serve to temporarily store a full p age of print-image dat a before the data is
sent to the print engine. Increasing the RAM will increase performance of graphic intense printing
operations but it will not increase the I/O buffer space or cause the printer to print more pages
per minute.
l Nonvolatile memory (NVRAM)—Stores information about the I/O and print environment
configuration. The printer keeps the contents of NVRAM when the power is turned off or
disconnected. (As in other HP LaserJet printers, downloaded fonts and macros are saved in
conventional RAM and are lost when power is turned off.)
l Interfaces
• P arallel interface—Receives incoming data throu gh its IEEE1284 B interf ace con nector. The
IEEE1284 B interface provides high-speed, two-way communication between the printer and
the host, letting the user change printer settings from the host computer.
• USB—Receives incoming data through its universal serial bus (USB) connector. The USB
interface provides high-speed, two-way communication between the printer and the host,
letting the user change printer settings computer.
• EIO—The PCI-b ased enhance d input/ou tput (EIO) slot s suppo rt a wide range of print servers
and other add-on devices. HP JetDirect EIO cards provide high-speed, two-way
communication for network printing over Ethernet, Ethernet and LocalTalk, Token Ring, or
Fast Ethernet networks.
• FIR—This port is compliant with the specifications determined by the Infrared Data
Association (IrDA). On the right side of the FIR port is a status light that indicates when the
port is active. The FIR port transmits data at speeds of up to 4 MB per second. When the
infrared (IR) connection is established, the FIR status light comes on. If the connection is
broken, or when the print job is complete, the FIR status light goes off.
Formatter subsystem
Resolution Enhancement technology (300 and 600 dpi only)
Contains circuitry for Resolution Enhancement technology (REt), which modifies the standard video
dot data on its way to the engine controller assembly to produce smoothed black-t o-white
boundaries. The default is on.
Print-density adjustment
Affects the line width (boldness) of the print image . This is accomplished b y v arying the developer dc
bias, which controls the amount of toner applied to the photosensitive drum. Settings range from 1
(lightest) to 5 (darkest). The default is 3.
EconoMode
Uses approximately 50 percent less toner than standard mode printing by reducing the dot density.
Users can adjust EconoMode, which can also be thought of as draft mode, through software
applications. The default setting is off. EconoMode does not affect print speed or memory usage.
C7058-90936 Printer functionality and operation 75
Memory management
This printer uses various methods to conserve and make the most of available memory. Several of
these methods are explained below.
Memory Enhancement technology (MEt)
MEt enhances the printer's standard memory through a variety of font and data compression
methods. MEt also automatically compresses fonts for desktop publishing applications. MEt is
available in all printing modes (PCL 5e, PCL 6, and HP PS emulation). When printing graphics, MEt
analyzes each page as it is being printed and automatically ap plies a variety of compression
techniques to print the complete pag e at th e co rr ect reso lu tio n.
Image Adapt
Image Adapt uses a compression technique to allow p rinting of fu ll-page graphics using the printer's
base memory. Image Adapt is only used in PCL 5e (PCL 6 and HP PS emulation do not require
Image Adapt). The available settings are auto, on, and off. The default is auto.
If Image Adapt is used some data might be lost. To see if there has been some loss of graphic detail,
print a self-test page and check the Image Adapt Used line in th e Printer Information section. If the
printer invoked Image Adapt since the last time the self test was printed (or the last time the printer
was turned off and on), that line reads “Image Adapt Used: Yes.”
Page Protect
A page's complexity (rules, complex graphics, or dense text) might exceed the printer's ability to
create the page image fast enough to keep pace with the engine's printing process. If a page is too
complex, it might print in parts (for example, the top half of data on one page and the bottom half on
the next page). Some print data loss is likely in these instances, and the printer's Attention light
flashes.
Page Protect allows the formatter to create the entire page image in memory before moving the
paper through the printer. This process ensures that the entire page is printed. The default is off,
which provides the best performance. Page Protect should only be enabled when necessary.
Printer Job Language overview
Printer Job Language (PJL) is an integral part of the printer’s configuration, in addition to the
standard Printer Command Language (PCL). PJL allows the printer to perform functions such as:
l Tw o- wa y comm uni cation with the host computer through an IEEE1284 B interface connection.
The printer can tell the host such things as the contro l pane l settin gs and allow the control panel
settings to be set from the host.
l Dynamic I/O switching allows the printer to be configured with a host on each I/O. The printer
can receive data from more than one I/O simultaneously until the buffer is full. This can occur
even when the printer is offline.
l Context-sensitive sw itc hing allo ws the printer to automatica lly recogniz e the persona lities (PS
or PCL) of each host and configure itself to serve that personality.
l Isolating print envir onment sett ings from one print job to the ne xt. F or e xample , if a print job is
sent to the printer in landscape mode, subsequent print jobs only print in landscape if they are
formatted for landscape printing.
For more information, see the HP LaserJet 2200 Series Printer Software Technical Reference. The
complete PJL Status Code listing is contain ed in the appe ndix of the Printer Job Language Technical
Reference. Also see HP’s website at www.hp.com.

Engine control subsystems
Laser/scanner control
Based on information received f r om th e eng ine co nt roller PCB, the formatter sends a direct signal to
modulate the laser diode on and off. The modulated laser beam strikes the surface of a rotating
scanning mirror, then a focusing lens directs the beam onto the photosensitive drum.
The printing system synchronizes the process by continuously monitoring the beam detect signal.
Paper -feed control
The engine controller PCB controls paper motion by continuously monitoring the various papersensor levers, and coordinating the timing with the other print processes and systems. See “Pickup/
feed system” on page 86.
Microswitch control
The engine controller PCB controls the following microswitches and reports any errors to the
formatter:
l Top door and toner cartridge switch. Activated if the top door is open. The toner cartridge is
detected electronically.
l Engine test switch. Activ at ed manually through an a ccess hole o n the side of the gear plate . This
switch causes the print engine to perform a self-test diagnostic, bypassing the formatter. See
"Engine test" in chapter 7.
Motor control
The engine controller PCB controls the following motors and reports any failures to the formatter.
See “Basic print-period operating sequences” on page 71.
l Main motor. Rotates during interim period (following initial power on), print, and last rotation, or
when the top cover is opened or closed.
l Scanner motor. Operates during the interim period and the print period.
l Fan motor. Rotates at full speed while the main motor is rotating and continues rotating for 30
seconds after the main motor stops. Rotates at full speed, half speed, and then stops during
power-on and the standby period.
l Reverse motor. A stepping motor responsible for changing the paper direction. It is capable of
clockwise and counterclockwise rotation.
Fuser-assembly control
The fuser assembly’s film contains a heater. The engine controller PCB controls the fuser heater
during the following temperature modes. See “Basic print-period operating sequences” on page 71.
l initial
l print
l between-page
l postprint
The engine controller PCB maintains the fuser at a temperature of 195 degrees C (383 degrees F)
during print temperature mode. If the fuser system overheats, reaching about 220 degrees C (428
degrees F), a relay opens the power circuit to the fuser heater, causing a fuser error message. If the
fuser system exceeds 230 degrees C (446 degrees F), the thermal fuse melts, cutting off power to
the fuser assembly. The engine controller PCB monitors the fuser heater temperature through a
thermistor.
78 Chapter 5 Theory of operation C7058-90936
Power supply and control
l The power s witch supplies a c power to the low-voltage po wer supply circuit when it is turned on.
This circuit supplies dc voltage (+24V, +5V, +3.3V) to the main motor, laser/scanner unit,
interlock switch, formatter, solenoids, paper feeder, high-voltage power supply, and formatter.
l The dc voltage supplied to th e high-v oltage pow er supply circuit is interrupted when the top cov er
is open.
l The overcurrent/overvoltage protection circuit in the low-voltage power supply automatically
turns off the output voltage when an overcurrent condition occurs beca us e of a sh ort or
abnormal voltage on the load side.
l When input power is turned off then on, the protection circuit automatically resets. The low-
voltage pow er supply circuit also contains a fuse that shuts off the power supply to the circuit
when overcurrent conditions occur. See “Engine control system” on page 77.
In response to the engine controller PCB, the high-voltage power supply circuit supplies dc and ac
voltage to the various parts of the image formation system.

Image formation system
The image formation system is the central hub of the printer. The system consists of the cartridge,
transfer charging roller, and fuser unit.
When a print command is sent from the formatter, the engine controller drives the main motor to
rotate the photosensitive drum, primary charging roller, developing cylinder, transfer charging roller,
and pressure roller.
The primary charging roller uniformly applies negative charges to the photosensitive drum surface.
To form a latent image on the photosensitiv e drum, the lase r beam modulat ed b y the vid eo signals is
exposed on the photosensitive drum surface.
The toner on the developing cylinder develops the latent image formed on the photosensitive drum
into a visible image, which is transferred onto media by the transfer charging roller. The transferred
toner is changed to a permanent image by heat and pressure in the fuser unit. The cleaning blade
scrapes off residual toner on the pho to se nsitive drum. The potential on the drum is made uniform by
the primary charging roller in preparation for the next latent image.

Photosensitive drum
The photosensitive drum is the heart of the image formation system. This drum’s special properties
allow an image to form on the drum's surface and then transfer to paper. The drum is an aluminum
cylinder coated with an organic-photoconductive material (OPC). The photosensitive drum’s
aluminum base is electrically connected to ground. The OPC material becomes electrically
conductive when exposed to light. Areas not exposed to light remain nonconductive and maintain
their negative charge.
Figure 41. Photosensitive drum
Cleaning stage
At the cleaning stage, the photosensitive drum's surface is prepared to hold an image. During
printing, the drum rotates completely several times per printed page. Befo re forming the image for a
given section of print, a cleaning blade removes toner from the previous rotation of the drum. The
toner cartridge stores waste toner and prevents it from being used in later print jobs.
C7058-90936 Printer functionality and operation 81
Figure 42. Cleaning stage
Conditioning stage
At the conditioning stage, the primary charging roller applies a uniform negative charge on the
photosensitive drum’s surface. The primary charging roller erases any residual charges and
maintains a constant potential on the drum’s surface. In addition, the primary charging roller creates
a uniform negative potential on the drum's surface.
Figure 43. Primary charging roller
82 Chapter 5 Theory of operation C7058-90936
Writing stage
At the laser/scanner assembly, two laser beams focus onto the photosensitive drum and discharge
the drum's negative potential. This creates a latent electrostatic image, which later is developed into
a visible image.
Two small laser diode beams shine onto a ro tating, six- sided mirror. As the mirror rotates, the b eams
reflect off the mirror and sweep the page from left to right.
A set of lenses and mirrors focuses the horizon tal s weeping bea ms through the beam a ccess slots in
the rear of the toner cartridge and onto the photosensitive drum. Beca use the beams sweep the
entire length of the drum while the drum rotates, the entire circumference of the drum can be
covered. Each successive sweep of the beams is offset 1/1200th of an inch. This is how the printer
achieves its 1200 dpi resolution.
At the beginning of each sweep (before the beams reach the drum), the beam detect mirror reflects
the beams. The momentary pulse of light goes to the engine controller PCB, which converts the light
to an electrical signal used to synchronize other activities in the printer and to diagnose problems
with the laser/scanner assembly.
Portions of the drum not exposed to the laser still contain the unif orm negative potential (placed there
by the primary charging roller ), but those portions exposed to light have been discharged to ground
to form the latent electrostatic image.

Developing stage
At the developing stage, the latent electrostatic image is developed into a visible image on the
photosensitive drum. The developing cylinder consists of a metallic cylinder that rotates around a
fixed magnetic core inside the toner cavity. Toner is a powdery substance made of black, plastic
resin bound to iron particles, which the magnetic core of the developing cylinder attracts. A rubber
blade brushes the toner on the developing cylinder to a uniform thickness.
Note Charges in the photosensitive drum’s exposed areas are shown as positive in figure 45 even though
they are actually negativ e. This means that the photosensitiv e drum potential is higher than that of the
developing cylinder.
To obtain a negative surface charge, the toner particles r ub against each other and the developing
cylinder which is connected to a negative dc supply. The discharged (grounded) areas of the drum
exposed to laser light attract the negatively charged toner. The negatively charged (non-exposed)
areas repel the toner. An ac potential is applied to the developing cylinder to decrease the attraction
between the toner and the cylinder’s magnetic core and to increase the repelling action of toner
against the areas of the drum not exposed to laser light. This ac potential improves density and
contrast.
The print density setting (through the software) adjusts the developing cylinder’s dc bias to change
the force of attraction between the toner and drum.
