To clean the exterior
Use a soft, damp, lint-free cloth to wipe dust, smudges, and stains off the exterior of the 
device.
To clean the glass
Over time, specks of debris might collect on the scanner glass and affect performance. Use
the following procedure to clean the scanner glass. 
1. Turn off the device, and unplug the power cord from the electrical socket.
2. Tilt the device control panel forward.
3. Clean the glass strip with a soft cloth or sponge that has been moistened with nonabrasive 
glass cleaner.
CAUTIONDo not use abrasives, acetone, benzene, ammonia, ethyl alcohol, or carbon tetrachloride on
any part of the device; these can damage the  device. Do not place liquids directly on the 
glass. They might seep under it and damage the device. 
4. Dry the glass with a chamois or cellulose sponge to prevent spotting.

							Device does not turn on
Try the tips in this section if the device does not turn on.
Is power reaching the device?
●If you are using a power strip, make sure that the power strip is turned on. Or, try plugging
the device directly into the power outlet.
●Test the power outlet to make sure that it is working.
●If you have plugged the device into a switched outlet, make sure that the switch is on.
●Make sure that the power switch on the back of the device is turned on.
WARNING!
If the problem persists after you try the preceding remedies, the device might be experiencing a
mechanical failure. Unplug the device from the power outlet and contact HP. See the support
flyer that came with the device for information about contacting HP.

							The device control panel display has black lines or dots, or fades
Try the tips in this section if the device control panel display has black lines or dots, or fades.
Black lines or dots
CAUTIONStatic electricity can cause unexpected black lines or dots to appear on the device control
panel display. Do not touch the device control panel display if there is a chance that you have
collected a static electric charge (for example, by walking on carpet in a low-humidity
environment).
Unexpected lines or dots might appear on the device control panel display if the device
control panel display is exposed to a static electric charge. Wait until the black lines or dots
fade away (usually within a few minutes).
Note
Do not print while the black lines or dots are visible.
Do not turn the device off and on. This does not solve the problem.
Faded device control panel display
CAUTIONMagnets or strong electric fields can cause the device control panel display to fade. Do not
place the device near magnets or strong electric fields.
The device control panel display might fade if the device is exposed to magnets or strong
electric fields. Move the device away from the magnets or strong electric fields, and wait until
the device control panel display returns to normal (usually within a few minutes).
Note
Do not print while the device control panel display is faded.
Do not turn the device off and on unless you are moving it to a different location. This does
not solve the problem.

							Pages print but are totally blank
Try the tips in this section if pages exit the device, but have nothing printed on them.
Is the sealing tape still in the print cartridge?
The sealing tape might still be in the print cartridge. Remove the print cartridge and pull out the
sealing tape. Reinstall the print cartridge. Try printing the document again.
Does the configuration page print?
To check the device, print a configuration page. See Printing a configuration page for
instructions.
Does the document contain blank pages?
The document might contain blank pages. Check the document that you are printing to see if
content appears on all of the 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 automatic document feeder (ADF) with the print-side facing down. If the original is
loaded print-side up, the copy prints out blank.

							Pages did not print
Try these tips when the device does not print any pages.
Does a message appear on your computer screen?
See Onscreen error messages appear for more information.
Is media being pulled into the device correctly?
See Paper-handling problems exist for more information.
Are media jams present?
See Media jams occur in the automatic document feeder (ADF) or Media jams occur in the
printer for more information.
Is the parallel or USB Device Cable (A/B) working, and is it
connected correctly?
The parallel or USB Device Cable (A/B) might be defective. Try the following remedies:
●Disconnect the parallel or USB Device Cable (A/B) 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 Device Cable (A/B).
See 
Ordering HP parts and accessories.
●Contact the manufacturer of your computer about changing parallel port settings to an
extended capabilities port (ECP) mode.
Are other devices running on your computer?
●The device might not share a parallel port. If you have an external hard drive or network
switchbox that is connected to the same port as the device, the other device might be
interfering. To connect and use the device, you must disconnect the other device or you
must use two parallel ports on the computer.
●You might need to add another interface card. Hewlett-Packard strongly recommends an
ECP parallel interface card.
