HP Color LaserJet 3800 Printer series - Manual (Page 179)

When connected with a USB cable, the printer does not appear in the Desktop Printer Utility or the Apple System Profiler after the
driver is selected.
Cause Solution
NOTE The iMac and Blue G3 desktop Macintosh systems
meet all of the requirements to connect to a USB device.
Hardware troubleshooting
● Check that the printer is turned on.
● Verify that the USB cable is connected correctly.
● Check that you are using the appropriate high-speed USB cable.
● Ensure that you do not have too many USB devices drawing
power from the chain. Disconnect all of the devices from the
chain and connect the cable directly to the USB port on the host
computer.
● Check to see if more than two nonpowered USB hubs are
connected in a row on the chain. Disconnect all of the devices
from the chain and connect the cable directly to the USB port on
the host computer.
NOTE The iMac keyboard is a nonpowered USB hub.
Solving problems with Mac OS X
The printer driver is not listed in the Print Center or Printer Setup Utility.
Cause Solution
The printer software might not have been installed or was installed
incorrectly. Make sure that the printer PPD file is in the following hard-drive
folder:
Library/Printers/PPDs/Contents/Resources/
<lang>.lproj , where <lang> is the two-letter language code for
the language that you are using. If necessary, reinstall the software.
See the getting started guide for instructions.
The PPD file is corrupt. Delete the PPD file from the following hard-drive folder: Library/
Printers/PPDs/Contents/Resources/<lang>.lproj ,
where <lang> is the two-letter language code for the language that
you are using. Reinstall the software. See the getting started guide
for instructions.
The printer name, IP address, or Rendezvous host name does not appear in the printer list in the Print Center or Printer Setup
Utility.
Cause Solution
The printer might not be ready. Make sure that the cables are connected correctly, the printer is on,
and the ready light is on. If you are connecting through a USB or
Ethernet hub, try connecting directly to the computer or use a different
port.
The wrong connection type might be selected. Make sure that USB, IP Printing, or Rendezvous is selected,
depending on the type of connection.
