HP Fast InfraRed
Receiver
Overview
Thank you for purchasing the HP Fast InfraRed Receiver.
This device is an infrared (IR) adapter that complies with the
communications protocol specifications established by the
InfraRed Data Association (IRDA).
CAUTION
Only connect the HP Fast InfraRed Receiver to an
HP LaserJet printer or mopier. Connecting the HP Fast
InfraRed Receiver to a different device may damage the
device.
The HP Fast InfraRed Receiver enables wireless printing
from any IRDA-compliant portable device (such as a portable
computer) to HP LaserJet printers and mopiers equipped for
fast serial infrared operation.
Because this printer has HP JetSend Communications
Technology built in, the HP Fast InfraRed Receiver also
allows wireless printing from any HP JetSend-enabled IR
sending appliance.

2HP Fast InfraRed Receiver EN
The printing connection is maintained by positioning the
sending IR port within operating range of the receiving IR
port (see “Executing the Print Job” on page 10). Note that the
connection can be blocked by objects such as a hand, paper,
direct sunlight, or any bright light shining into either IR port.
System Requirements
In order to print with the HP Fast InfraRed Receiver, you will
need:
zHP LaserJet printer or mopier equipped with fast serial
infrared capability
zIRDA-compliant portable or other IR-capable host
supporting IRLPT or HP JetSend over IR
zMicrosoft®Windows®9x, Mac OS 8.5, or Apple
LaserWriter 8.6 driver or higher
Note Older non-IRDA-compliant portable computers may not be
compatible with the HP Fast InfraRed Receiver. If you
experienceproblemswhenattemptingtoprintwiththeHP Fast
InfraRed Receiver, contact the manufacturer or dealer of your
portable computer to verify compatibility with the IRDA
standard.

Follow the instructions below to print a configuration page.
1Turn the printer’s power switch off.
2Attach the HP Fast InfraRed Receiver to the IR port on
the rear of the HP LaserJet printer.
3Turn the printer’s power switch on.
4On the control panel, make sure the printer is on and the
READY message is displayed.
5Press Menu until the display reads INFORMATION MENU.
6Press Item until the display reads PRINT
CONFIGURATION.

7Press Select to print the configuration page.
The configuration page shows the printer’s current
configuration.
An HP JetDirect network configuration page will also print
for networked printers and mopiers.
A configuration summary prints. On the first page of the
printout, under
Installed Personalities and Options , check
for “IR POD (IRDA-Compliant).”
The HP Fast InfraRed Receiver can be placed on a table or
attached to the side of the printer using the Velcro fasteners
shown in Figure 3 on page 7.
To attach the HP Fast InfraRed Receiver on the side of the
printer, continue with steps 1 and 2.
1Attach one Velcro faster to the round depression on the
underside of the HP Fast InfraRed Receiver (see
Figure 3).
2Attach the remaining Velcro fastener to the side of the
printer (see Figure 3).
When the HP Fast InfraRed Receiver is situated on the
printer, it should be close to the printer’s front edge as shown
in Figure 4. This location allows for the largest possible area
in which the portable computer’s IR port can operate. The
required alignment of devices is described in “Executing the
Print Job” on page 10.

Installing the IR Driver in Windows 9x
If your version of Windows does not have the
HP Fast InfraRed driver pre-installed, you can download
it from the Internet at no charge. The address is
http://www.microsoft.com/windows. Use the search
feature on the web page to locate the correct driver.
After downloading the InfraRed driver, complete these steps:
1Start the SETUP.EXE program to invoke the Windows 95
Add InfraRed Device wizard.
2When the wizard announces
New Hardware Found
events for the IR serial and parallel ports, you can enable
the IR device immediately after the wizard is finished.
3Restart the computer.
Installing the IR Driver in Macintosh OS
The HP Fast InfraRed driver is pre-installed with Mac OS 8.5
or newer. If your Mac OS is older than 8.5, you can download
the Apple LaserWriter 8.6 driver, which supports IR printing,
from the World Wide Web at no charge from www.apple.com.

Executing the Print Job
1Align your portable computer (or other portable device
equipped with an IRDA-compliant IR window) within
1 meter (2 to 3 feet maximum) of the HP Fast InfraRed
Receiver. The IR window must be at an angle of +/- 15
degrees to ensure an effective connection for printing.
Figure 5 illustrates the required alignment of devices
necessary for printing.
Figure 5 Alignment of Devices Used for Printing

EN HP Fast InfraRed Receiver 11
2Execute the print job. The status indicator on the HP Fast
InfraRed Receiver lights up, and, after a short delay, the
printer status panel displays a PROCESSING JOB
message.
If the status indicator does not light up, realign the HP Fast
InfraRed Receiver with the IR port on the sending device,
re-send the print job, and maintain the alignment of all
devices as shown in Figure 5. If you have to move the
equipment (for example, to add paper), make sure that all
devices remain within the range of operation shown in
Figure 5. Only then is the required connection maintained. If
the connection is interrupted before your print job is
complete, the HP Fast InfraRed Receiver status indicator
turns off. You have up to 40 seconds to resume the
connection and continue the job. If the connection is resumed
within this time, the status indicator lights up again.
Note The connection is permanently broken if the sending port is
moved out of operating range (see Figure 5), or if anything
passing between the ports blocks transmission for more than
40 seconds. (This block could be a hand, paper, or even direct
sunlight). Depending on the size of the job, printing with the
HP FastInfraRedReceivermaybeslightlyslowerthanprinting
with a cable connected directly to the parallel port.

12 HP Fast InfraRed Receiver EN
Handling and Care
The HP Fast InfraRed Receiver is a delicate electronic device
that should be treated with the same care as your printer. In
addition, follow these precautions at all times:
zAvoid discharging static electricity to the HP Fast
InfraRed Receiver.
zDo not place objects on the HP Fast InfraRed Receiver.
Cleaning the HP Fast InfraRed Receiver
Always keep the device’s IR window free from dust and
grease.
To remove dust from the HP Fast InfraRed Receiver’s
surface, use a soft, non-abrasive cloth. Hardened dirt may be
removed with a cloth slightly dampened in soapy water.
Do not allow water to get into openings on the device.
Do not use abrasive cleaners, acrylic or lacquer paint
thinners, and cleansers with an acetone or solvent base,
such as MDC or EDC. These will damage the HP Fast
InfraRed Receiver’s plastic case.

EN HP Fast InfraRed Receiver 13
Troubleshooting
If you have a problem while operating the HP Fast InfraRed
Receiver, follow these steps:

is compatible with the HP Fast InfraRed Receiver, fulfills
system requirements, and you have performed the
correct hardware and software installation procedures.
2See the Troubleshooting Chart on page 14 to check if a
solution to your problem is provided.
3If you still have a problem, or think you may have a
defective HP Fast InfraRed Receiver, consult the support
section of your user’s guide.

Troubleshooting Chart
Condition Solution
IR port status indicator does not
light up. Make sure the printer is in READY mode and that the IR port you are printing from is IRDA-compliant and
within the range of operation described in
“Executing the Print Job” on page 10.
Make sure the HP Fast InfraRed Receiver is
properly connected to the printer.
Print the printer configuration page. Check that “IR
POD (IRDA Compliant)” is printed under
Installed
Personalities and Options.
Connection cannot be
established or transmission
seems to take longer than
usual.
Use a device that is IRDA-compliant; look for an
IRDA symbol on the device, or refer to the computer
user’s guide for IRDA specifications.
Make sure that the operating system on your
computer includes an IR driver and your application
uses the appropriate HP LaserJet printer driver.
(Note that complex pages take longer to print.)
Position the HP Fast InfraRed Receiver within the
range of operation (see “Executing the Print Job” on
page 10), and make sure that no object is blocking
the connection. (This object could be a hand, paper,
books, or even bright light.)
Make sure that the two IR ports are clean (free from
dirt and grease).
Bright light of any kind (sunlight, incandescent light,
fluorescent light, or light from an infrared remote
control, such as those used for TVs and VCRs)
shining directly into one of the IR ports may cause
interference. Make sure no bright light is shining
directly into either IR port.
Position the portable device closer to the IR port on
the printer.
