Note

Caution

The HP LaserJet 5Si HM (C3124A) supports 16-53 lb bond media from all
trays. However, performance in Tray 2 may not be as good with heavier
media due to the sharp turn in the paper path. For best performance, Tray
1, 3, or optional Tray 4 are recommended.

When using 16 lb bond media, only use fusing mode=STD PAPER.

Identification

Model and Serial Numbers

The model number and serial numbers are listed on identification labels
located on the rear of the printer. The model number is alphanumeric, such
as C3166A for the HP LaserJet 5Si printer.

The serial number contains information about the Country of Origin, the
Revision Level, the Production Code, and production number of the printer.

The rear labels also contain power rating and regulatory information as
shown in Figure 1-1.

Sample Model and Serial Number Label

The identification labels for the 2000 Sheet High Capacity Input Tray are
located on the back panel, directly below the identification labels on the
printer.

To locate the identification labels for the 8 bin Multi-Bin Mailbox and 5 bin
Multi-Bin Mailbox with Stapler, detach the unit from the printer. The
identification labels are located on the bottom right of the front side (side
that attaches to printer).

Media Selection Guidelines

Product

Information

Note

More detailed specifications are in the HP LaserJet 5Si and 5Si MX User’s
Guide, and the HP LaserJet Printer Family Paper Specification Guide.
(See “Related Documentation and Training Media” later in this chapter.)

Paper

To achieve the best possible print quality and avoid paper jams, follow these
guidelines for selecting paper:

• Use only copier grade paper that meets all specifications in the paper

specification guide. Avoid paper with embossed lettering, perforations, or
texture that is too smooth or too rough.

• Colored paper should be of the same high quality as white photocopy paper.

The pigments must withstand the fusing temperature of 392°
(215° C for HP LaserJet 5Si Heavy Media printers) for 0.1 second without
deterioration. Do not use paper with a colored coating that was added after
the paper was produced.

• Pre-printed forms must be printed with non-flammable, heat-resistant inks

that do not melt, vaporize, or release hazardous emissions when subjected
to the fusing temperature of 392° F (200° C) (215° C for HP LaserJet 5Si
Heavy Media printers) for 0.1 second.

• A small sample of a new print media should be tested before purchasing

large quantities.

F (200° C)

Caution

Envelopes

To prevent severe printer damage, do not use envelopes that have windows,
clasps, snaps, or synthetic materials.

Print Envelopes to the Face-Up Bin only

Envelopes can be printed from Tray 1 and from the optional Envelope
Feeder. Choose envelopes that are well-constructed. They should lay flat
and be sharply creased. They should not be wrinkled, nicked, or otherwise
damaged. Envelope adhesive must be compatible with the heat and
pressure of the fusing process.

Product Information 1-11

Adhesive Labels

Use the following guidelines when selecting labels:

Caution

Tray 1 is required for printing adhesive labels.
Print labels to the Face-Up Bin only.
This printer does not support use of labels with any exposed spaces.
Do not attempt to print on label sheets after any of the labels have been

removed from the sheet. Damage to the printer may result.

• Labels must be arranged on the carrier sheet so that there are no exposed

spaces on the sheet. Using label stock with spaces between rows or columns
of labels can often result in labels peeling off during printing, causing
serious jamming and possible printer damage.

• The top sheet (printing surface) must be of copier quality and provide good

toner adhesion.

• The carrier sheet (backing sheet) must be compatible with the temperatures

and pressure of the fusing process, and must be coated for easy release of
the top sheet.

• The adhesive must be stable at the 392° F (200° C) temperatures

encountered for 0.1 second in the fusing process, and must not produce
emissions that exceed exposure levels or threshold limits established by
OSHA and other safety agencies. Adhesives must not come into direct
contact with any part of the printer.

A wide selection of suitable labels may be ordered through
Hewlett-Packard. Available sizes are listed in the HP LaserJet Printer

Family Paper Specification Guide.

Transparencies

Caution

1-12 Product Information

Tray 1 (Multi Purpose) is required for printing transparencies.
Print transparencies to the Face-Up Bin only.

Overhead transparencies used in HP LaserJet printers must be able to
withstand the 392° F (200° C) temperatures encountered in the printer’s
fusing process for 0.1 second. Suitable transparency film is available
through Hewlett-Packard. Refer to the HP LaserJet Printer Family Paper
Specification Guide for details.

Storing Print Media

Follow these guidelines when stacking and storing print media:

• Store paper in its ream wrapper until ready to use.

• Re-wrap partially used packages of media before storing.

• Stack each carton upright and squarely on top of the other.

• Store envelopes in a protective box to avoid damaging the envelope edges.

• Keep stored media away from temperature and humidity extremes.

• DO NOT store cartons or reams directly on the floor where they will absorb

a higher moisture content. Instead, place cartons on a pallet or on shelves.

• DO NOT store individual reams in a manner that causes them to curl or

warp along the edges.

• DO NOT stack more than six cartons on top of each other.

• DO NOT place anything on top of media, regardless of whether the paper is

packaged or unpackaged.

Product

Information

• DO NOT store printed documents in vinyl folders (which may contain

plasticizers) or expose the documents to petroleum based solvents.

Shipping Print Media

When shipping print media through different environments, plastic wrap all
cartons on the shipping pallet. When shipping media across bodies of
water, wrap individual cartons as well. Packaging must protect the media
from physical damage.
