Troubleshooting HP Fast InfraRed Receiver problems
Item Explanation
FIR port status
indicator does not
light up.
Make sure that the printer is in
READY
mode and that the FIR port
you are printing from is IRDA-compliant and within the range of
operation described in the user guide for the HP Fast InfraRed
Receiver.
Make sure that the HP Fast InfraRed Receiver is properly connected
to the printer.
Print a configuration page (see “Configuration page” on page 152).
Make sure that “FIR POD (IRDA Compliant)” is printed under
Installed Personalities and Options.
Connection cannot be
established or seems to
take longer than usual.
Use a device that is IRDA-compliant; look for an IRDA symbol on
the device or see the computer’s user guide for IRDA specifications.
Connection often cannot take place because the computer does
not have the software that is required for FIR. Make sure that the
operating system on your computer includes an FIR driver and your
application uses an HP LaserJet 4100, 4100N, 4100TN, 4100DTN,
or compatible driver.
Note that complex pages take longer to print.
Position the HP Fast InfraRed Receiver within the range of operation
described in the user guide for the HP Fast InfraRed Receiver. 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 might
cause interference. Make sure that no bright light is shining directly
into either IR port.
Position the portable device closer to the FIR port on the printer.
The printer prints only
part of a page or
document.
The connection has been broken during transmission. If you move
the portable device during transmission, the connection can be
broken. IRDA-compliant devices are designed to recover from
temporary connection interruptions. You have up to 40 seconds to
re-establish the connection (depending on the portable device
being used).
