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 page 134). 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.
Make sure that the operating system on your computer includes an
FIR driver and your application uses an HP LaserJet 4050, 4050 N,
4050 N, 4050 TN, 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 FIR 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 FIR ports might
cause interference. Make sure that no bright light is shining directly
into either FIR 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).
