Product will not turn on or print
Is the parallel or USB cable working and connected correctly?
The parallel or USB cable might be defective. Try the following:
● Disconnect the parallel or USB cable at both ends and reconnect it.
● Try printing a job that has printed in the past.
● Try using a different IEEE 1284-B-compliant parallel cable or USB cable. See Ordering
HP parts and accessories.
● Contact the manufacturer of your computer about changing parallel port settings to an ECP
(extended capabilities port).
Are other devices running on your computer?
● The HP LaserJet 3300 series product may not share a parallel port. If you have an external
hard drive or network switchbox connected to the same port as the HP LaserJet 3300, the
other device might be interfering. To connect and use the HP LaserJet 3300, you must
disconnect the other device or you must use two ports on the computer.
● You might need to add another interface card. Hewlett-Packard strongly recommends an ECP
parallel interface card.
Is the product getting power?
● If you are using a power strip, make sure the power strip is on. Or, try plugging the product
directly into the power outlet.
● Test the power outlet to make sure it is working.
● If you have plugged the product into a switched outlet, make sure the switch is on.
● If you have a 220V product, make sure the power is switched on.
WARNING! If the product still does not turn on after you try the above tips, it may have a mechanical failure.
Unplug the product from the power outlet and contact HP. Refer to the support flyer that came with
the product for information on contacting HP.
Pages print but are totally blank
Is the sealing tape still in the print cartridge?
The sealing tape may still be in the print cartridge. Remove the print cartridge and pull out the
sealing tape. Reinstall the print cartridge. Try printing the file again.
Does the file have blank pages?
The file may have blank pages. Check the file you are printing to determine whether there is
content on all of its pages.
Is the original loaded correctly?
If you are making a copy, the original might be loaded incorrectly. The original must be loaded into
the ADF face up. If loaded print side down, the copy will print out blank.
