36 Chapter 1 Product information ENWW

Media specifications

Before purchasing large quantities of print media, make sure that it meets the requirements specified
in this service manual and in the HP color LaserJet 9500 User Ref erence Guide. Alwa ys test the print
media before buying large quantities.

Hewlett-Packard neither warrants nor recommends the use of a particular brand of paper or print
media other than HP media. Media properties are subject to manufacturing changes, and HP has no
control over such changes. Although testing the media helps to characterize the performance and
the manufacturer’s process quality, the customer assumes all responsibility for the quality and
performance of media.

CAUTION Using print media that does not meet HP specifications might cause problems for the product, requiring

repair. Such repair is not covered by the Hewlett-Packard warranty or service agreements.
The HP color LaserJet 9500 series printers accept a variety of media, such as cut-sheet paper

(including up to 100 percent recycled fiber-content paper), 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 and in the print media guide can cause the following problems:

z poor print quality
z increased jams
z premature wear on the printer, requiring repair

Guidelines for selecting media

This product accepts a variety of media, such as cut-sheet paper (including recycled paper),
envelopes, labels, transparencies, and custom-size paper. Properties such as weight, grain, and
moisture content are important factors that affect product performance and print quality.

Selecting media by type and size at the control panel and in the printer driver results in significantly
better print quality for heavy paper and glossy paper. Using the wrong setting can result in
unsatisfactory print quality. Always print by type for special print media such as labels or
transparencies. Always print by size for envelopes.

The product can use a variety of paper and other print media in accordance with the guidelines in this
manual. Paper that does not meet these guidelines can cause the following problems:

z poor print quality
z media jams and multiple-sheet feeds
z premature wear on the printer, requiring repair

Note Some print media might meet all of the guidelines in this manual and still not produce satisfactory

results. This might be the result of improper handling, unacceptable temperature and humidity levels,
or other variables over which HP has no control.

If you are unsure what type of paper you are loading (such as bond or recycled), check the label on
the package of paper.

z See “Basis weight field test” on page 46 for information about measuring basis weight.
z See “Caliper field test” on page 48 for information about measuring caliper.
z See “Paper finish field test” on page 48 for information about smoothness.

Hint Do not purchase more media than can be easily used in a short time (about 3 months). Media that is

stored for long periods experiences heat and moisture extremes that can be damaging. Planning is
important to prevent damage to a large supply of media.

Special media specifications

Envelope specifications

Successful printing on envelopes depends upon the quality of the envelopes. Envelope fold lines can
vary considerably, not only between manufacturers, but also within a box from the same
manufacturer. When selecting envelopes, consider the following components:

z Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 inch) curl,

and have well-constructed seams.

z Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged.
z Temperature: Envelopes should be compatible with the heat and pressure produced by the

printer.

Figure 10. Sample seams

ENWW Chapter 1 Product information 41

Note Print on envelopes from tray 1 only . Send envelopes straight through the printer, entering at tray 1 and

exiting from the face-up bin.
For the best print quality, position margins no closer than 15 mm (0.6 inch) from the edges of the

envelope. A void printing over the area where the envelope seams meet.

Envelopes with adhesive strips or multiple flaps

Envelopes with a peel-off adhesive strip, or with more than one flap that folds over to seal, must use
adhesives that are compatible with the heat and pressure of the printer. The extra flaps might cause

wrinkling, creasing, or jams.

Label specifications

CAUTION T o a void damaging the printer, use only labels that are recommended for laser printers. Never print on

the same sheet of labels more than once and never print on a partial sheet of labels.
When selecting labels, consider the quality of each component:

z Adhesives: The adhesive material should be stable at 200° C (392° F), which is the printer

fusing temperature.

z Arrangement: Do not use labels that have exposed backing between them. Labels can peel off

sheets with spaces between the labels, causing jams.

z Curl: Prior to printing, labels must lie flat with no more than 13 mm (0.5 inch) of curl in any

direction.

z Condition: Do not use labels that have wrinkles, bubbles, or other indications of separation.

Note Use only tray 1 to print on labels. Send labels straight through the printer, entering at tray 1 and exiting

from the face-up bin.

Card stock construction

When selecting card stock, consider the quality of each component:

z Smoothness: 135- to 220-g/m

2

(36- to 58-lb bond) card stock should have a smoothness rating

of 100 to 180 Sheffield.

z Curl: Card stock should lie flat with less than 5 mm (0.2 inch) of curl.
z Condition: Make sure that the card stock is not wrinkled, nicked, or otherwise damaged.

Note When printing on card stock, make sure to set the CARDSTOCK type at the control panel when you load

the tray, and in the printer driver when you print your print job.

Transparency specifications

To avoid damaging the printer, use only transparencies that are recommended for use in color laser
printers.

z Construction: Prior to printing, transparencies should lie flat with less than 10 mm (0.39 inch)

curl.

z Condition: Transparencies should not be wrinkled, nicked, or otherwise damaged.
z Temperature: Transparencies should be stable at 190° C (374° F), which is the printer fusing

temperature.

z Size: 5 mm thick (0.005 inch)

Note If problems occur while printing on transparencies, use tray 1. Send transparencies straight through

the printer, entering at tray 1 and exiting from the face-up bin.

CAUTION Transparencies used in the printer must be able to withstand 190° C (374° F), the printer fusing

temperature.

Preprinted forms and special letterhead

Many preprinted forms and special letterhead papers perform well in HP LaserJet printers. However,
these papers undergo processes that alter their original characteristics, and care must be taken to
ensure they conform to HP specifications. All special papers should be wrapped in moisture-proof
wrapping when purchased from the paper converter or printing house.

Forms and letterhead must be printed with inks that conform to the following specifications:

z Only use ink that is heat-resistant, and that will not melt, scorch, or release hazardous emissions

when subjected to 200

z Inks must have resistance to silicon oils, and must not be affected by resin components in toner.
z Inks must not be flammable.
z Inks must not “offset” (transfer from the printed paper onto the printer, contaminating internal

printer components). The principle cause of offset is ink that is not fully dried or that cannot
withstand the printer fusing temperature.

Note Do not use forms or letterhead that was produced by using low-temperature inks (the kind used with

thermography).

° C (392° F) for 0.1 second.

ENWW Chapter 1 Product information 43

Embossed media

Embossed media is not recommended for use in HP LaserJet products. Media is embossed by
stamping an image into the media by compressing the media fibers together at approximately 200
(392

° F), and sometimes by applying a thin metal foil to the surface. The product fusing process can

loosen the foil; loose foil can interfere with the mechanical and electronic operation of the product.
Embossed paper, with or without foil, can also cause multifeed jams. Multiple embossed print media

sheets tend to stick to one another.

Glossy media

Keep these considerations in mind when selecting or printing on glossy media:

z Print quality can vary with the media used. For best results, use HP-brand glossy media.
z When using media that has only one glossy side, make sure to orient the media so that the

printer prints on the glossy side.

Note When printing on glossy media that is between 75 g/m2 (20-lb bond) and 105 g/m2 (28-lb bond) in

weight, make sure to set the GLOSSY type at the control panel when you load the tray , and in the printer
driver when you print your print job.

° C

When printing on HP-brand glossy media that is between 106 g/m

2

(29-lb bond) and 163 g/m2 (43-lb
bond) in weight, make sure to set the HP HEAVY GLOSSY type at the control panel when you load the
tray, and in the printer driver when you print your print job.

When printing on non HP-brand glossy media that is between 106 g/m

(29-lb bond) and 163 g/m

2

(43-lb bond) in weight, make sure to set the NON HP HEAVY GLOSSY type at the control panel when you

load the tray, and in the printer driver when you print your print job.

Media with cutouts or perforations

Avoid media with cutouts or perforations for these reasons:

z Cut fibers absorb more moisture and can increase waviness and media curl. This decreases the

print quality near the cutout or perforated area.

z Cutting knives leave a sharp edge on the cutout or perforation. If the sharp edge is facing the

print cartridge drum during printing, it can scratch the drum surface.

z If printing occurs over a cutout hole, the transfer roller is contaminated with unused toner,

creating light streaks on the paper.

Chemically treated media

Coatings such as lacquers, polymers, laminations, or other chemicals protect the paper, but can
cause problems in the fuser and transfer areas of HP LaserJet products. The surface resistivity and
moisture content can be greatly altered, resulting in print-quality problems. Hard surface coatings
increase wear on the rollers and media guides. All chemically treated media must meet
Hewlett-Packard specifications for fusing compatibility.

Synthetic media

Synthetic media (those manufactured from man-made fibers) do not perform as well as bond media
in any printer or MFP, especially HP LaserJet products. All synthetic media must meet Hewlett­Packard specifications, especially for caliper and fusing compatibility.

44 Chapter 1 Product information ENWW

Other special media

z Non-standard sizes. Check minimum and maximum supported sizes on page 38.
z Carbonless media. Carbonless media (NCR) is not supported by HP LaserJet products.
z Recycled media. Choose recycled media that meets Hewlett-Packard specifications. Note that

recycled media might not be as bright as indicated in the specifications. Hewlett-Packard
recommends that recycled media contain no more than 5 percent groundwood. See “Testing
media specifications” on page 45.

Storing print media

Ideally, the printing and media storage environment should be at or near room temperature, and
should not be 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 in a room to increase. As a
package of 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.

Therefore, paper storage and handling are as important as the paper-making process itself. Paper
storage environmental conditions directly affect the feed operation.

Users should not purchase more paper than can easily be 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 packages can remain stable for several months before use. Opened
packages of paper have more potential for environmental damage, especially if they are not wrapped
with a moisture-proof barrier.

The paper storage environment should be correctly maintained to ensure optimum printer
performance. The required condition is 20

° to 24° C (68° to 75° F), with a relative humidity of 45

percent to 55 percent. The following guidelines should be helpful when evaluating the paper’s
storage environment:

z Paper should be stored at or near room temperature.
z The air should not be too dry or too humid (because of the hygroscopic properties of paper).
z The best way to store an opened package 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.

Envelope storage

Proper storage of envelopes contributes to good print quality. Env elopes should be stored flat. If air is
trapped in an envelope, and creates an air bubble, then the envelope might wrinkle during printing.

Testing media specifications

The following tests describe ways to evaluate media with respect to the specifications listed in this
manual, and the HP LaserJet Printer Family Print Media Guide. See “Media assessment tools and
suppliers” on page 50 for help obtaining the tools that are needed to perform these tests.

ENWW Chapter 1 Product information 45

Basis weight field test

The basis weight should be indicated on the package label. If the label is not available, a simple field
test can determine the basis weight of paper. The basis weight of paper is equal to the weight of
2,000 sheets of paper, or about four full packages. Weigh a full package on a postal scale and then
multiply that weight by four. Or weigh 10 sheets of paper, divide that weight by 10, multiply by 2,000,
and then divide by 16.

Example 10 sheets weigh 1.6 ounces ÷ 10

0.16 ounce x 2,000 = 320 ounces
320 ounces ÷ 16 ounce/lb = 20 lb paper (letter only)

Table 16. Determining basis weight of paper

Amount Formula

Four packages weight = basis weight
One package weight x 4 = basis weight
10 sheets (weight divided by 10) x 2,000 and then divided by 16 = basis weight

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 the appropriate weight in the paper weight equivalence table.

Paper weight equivalence table

Use this table to determine approximate 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. cover­weight paper, locate the bond weight (in row 3, second column) and scan across the row to the cover
weight (in the fourth column). The equivalent is 28 lb. Shaded areas indicate a standard weight for
that grade.

Caliper field test

The specified caliper differs according to the type of media used. Caliper can be measured in the
field by 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 example, if the fibers
are compressed, 6 mm (0.24 inch) paper could measure as little as 3 mm (0.12 inch). Always use the
fine adjustment 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, a new U.S. dollar bill can be used as a benchmark for comparing paper texture. A dollar bill
has a finish of 350 Sheffields. If paper feels rougher than 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 package or a sheet of paper can be measured with a moisture meter. In general, only evaluate

customer storage environment when trying to determine if excess moisture or dryness is the cause
of a problem with paper.

Grain field test

Grain direction is usually specified on the package label (written out “long” or “short”). The paper
dimensions listed on the label also indicate grain direction. For example, short-grain letter-size paper
labels are marked “11 by 8.5,” and long-grain paper labels are marked “8.5 by 11."

If grain direction is not included on the package label, it can be determined by a simple wet test. 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. On diagonal grain envelopes, the two opposite corners will curl toward each other.

Figure 12. Long, short, and diagonal grain curl

48 Chapter 1 Product information ENWW

Curl field test

To check for paper curl, place a single sheet of paper on a flat surface and measure curl at the
greatest deflection, holding a ruler perpendicular to the flat surface.

Figure 13. 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 package label to determine the fiber composition of the paper. Paper is usually specified as
xerographic 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 buildup from preprinted logos or letterhead, and for toner buildup or
spots. Inspect printed output for repetitive defects and smearing. If necessary, hav e users contact the
forms vendor to ensure paper fusing compatibility with HP LaserJet printers.

understand the context of the term.

The HP color LaserJet 9500 is designed to be diagnosed over the phone, and repaired in the field.
Repair of the printer normally begins with a three-step process:

1 Isolate the problem to the major system (the host computer, the network or server, or the printer).
2 Isolate the problem to the print engi ne, the input device, the ADF/scan engine, or the finishin g

device. See the proceeding note.

3 Troubleshoot a print-engine problem by using the troubleshooting procedures described in

chapter 7 of this manual.

After a faulty part is located, repair is usually accomplished by assembly-level replacement of field
replaceable units (FRUs). Some mechanical assemblies can be repaired at the subassembly level.
Hewlett-Packard does not support replacement of components on the printed circuit assemblies.
Some parts can be installed by the customer.

Use this item to control the midtones (solid and very light color
fills are not affected) for each color plane. The default for each
color is zero. A larger negative number can result in lighter or
less dense midtones for a particular color plane, and a larger
positive number can result in darker or more dense midtones for
a color plane. Settings can be adjusted, for each color plane
(cyan, magenta, yellow, and black), individually as primary
transfer biases are charged.

Note

Newer versions of t he printer version and the MFP version
firmware allow the primary colors to be individually adjusted for
highlight, midtone, and shadow ranges.

Note

The changes are universal, and apply to all printed pages
regardless of the media type selected.

Note

The RESTORE COLOR VALUES menu returns the values to the

The defaul t value of each item is OFF. Use the RESTORE OPTIMIZE
option to reset all options to the factory default position (OFF).

z TRANSFER DOWN 1, TRANSFER DOWN 2, TRANSFER UP 1, and

TRANSFER UP 2: These settings co ntr o l T2 curr en t to corr ec t
for media types that show poor secondary transfer when a
predefined media type setting is used. Try the DOWN 1 and
DOWN 2 settings first. This might result in a darker image. If it
does not, some medias require that the value is set to UP 1 or
UP 2. It is possible to set these ON at the same time. If
multiple bits are set, the def ault (all OFF) is used. Using
smoother media results in better transfer; exceptionally
rough media can show problems that will not be addressed
by these settings.

z LEADING EDGE DOWN and LEADING EDGE UP: Use these

settings to compensate for poor transfer, missing toner,
discharge marks, and mottled appearance on the leading
edge of printed pages. To resolve these issues, try setting
LEADING EDGE DOWN first; however depending on the media
type, you might get better resu lts usin g LEADING EDGE UP.
LEADING EDGE UP set to ON increases the leading edge
secondary transfer bias. LEADING EDGE DOWN set to ON
decreases the lead ing edge second ary transf er bia s. If the UP
and DOWN settings are both set to ON, they are set to OFF.

Note

Try the other media type settings first, becau se this is a un iv er sal
setting and applies to all pages that are printed, regardles s of the
selected media type.

z HIGH COVERAGE 1, HIGH COVERAGE 2, and HIGH COVERAGE 3:

HIGH COVERAGE 1 a nd HIGH COVERAGE 2 control th e sett ing of
the yellow dot pattern that is designed to eliminate certain
types of banding (47 mm) in high coverage.

• HIGH COVERAGE 1: Yellow dots appear in a 10-by-10 mm
pattern for half-speed printing , and an 8- by -8 mm p attern
for full-speed printing. The default is OFF; when set to ON,
the yellow dots are off. If the yellow dots are
objectionabl e and the 47 mm band is ac cep table (a line
or band is visible once at 47 mm from the start and the
stop of a strip of color), turn this item ON. Otherwise, leave
this item OFF.

• HIGH COVERAGE 2: Yellow dots appear in an 8-by-8 mm
pattern for full-speed printing, and 10-by-10 mm for half­speed printing. The default is OFF; when set to ON, the
yellow dots are in an 8-by-8 mm pattern for half- and full­speed printing. If a line rec urs e v ery 47 mm from the start

Service ID

This item allows the date that the printer was first used to be shown through the control panel,
eliminating the need for customers to keep paper receipts for proof of warranty. Because the printer
does not have an internal clock, the service ID date’s availability is dependent on the printer being
connected to a source that can provide the date, such as the installer, the driver, or the embedded
Web server. In cases where the printer is not connected to a date source, the service ID will not be
available, and the control panel will display 000000.

86 3 Product configuration ENWW

Restoring the Service ID

If you replace the formatter, the date is lost. Use this menu item to reset the date to the original date
that the printer or MFP was first used. The date format is YYDDD. Calculate the date as follows:

1 T o calculate YY, subtract 1990 from the calendar year. For instance, if the printer or MFP was first

used in 2002, calculate YY as follows: 2002 – 1990 = 12. YY = 12.

2 To calculate DDD, use the following formula:

30(calendar month – 1) + calendar day = DDD. If the calendar day is 31, use 30 instead. For
instance, if the printer or MFP was first used on October 17, calculate DDD as follows:

a Subtract 1 from 10 (October is the tenth month of the year): 10 – 1 = 9.
b Multiply 9 by 30: 9 x 30 = 270.
c Add 17 to 270: 270 + 17 = 287. Thus, DDD = 287.

Converting the Service ID to an actual date

You can use the printer’s Service ID number to determine whether the product is still under warranty.
Convert the Service ID into the installation date as follows:

1 Add 1990 to YY to get the actual year that the product was installed.
2 Divide DDD by 30. If a remainder results, add 1 to the result. This is the month.
3 The remainder from the calculation in step 2 is the date.

Using the Service ID 12287 as an example, the date conversion is as follows:

1 12 + 1990 = 2002, so the year is 2002.
2 287 divided by 30 = 9 with a remainder of 17. Because a remainder results, add 1 to 9 to get 10,

which represents October.

3 The remainder in step 2 is 17, so that is the date.
4 The complete date is 17-October-2002.

Use the following steps to perform a NVRAM restore:

1 Turn the printer off and replace the formatter.
2 Enter the NVRAM reset key sequence when the printer is turned on for the first time.
3 Critical values are copied from the disk to NVRAM.

The reset only works if the key sequence is entered the first time the printer is turned on after the
new board is installed. If the printer is turned on without entering the key sequence, all of the values
are set to what is in the NVRAM on the new board and the backup data on the disk is lost.

The hard disk is guaranteed to have the most current data backed up, so the updated data is always
accurate. Also, you do not have to wait f o r an automatic periodic disk sync before turning the printer
off to change the formatter.

Note The NVRAM reset sequence resets all NVRAM values when a hard disk drive is not used.
