Determining Printer Problems
Printer Does Not Turn On
Check to see if... Solution
Printer is not plugged in. Plug the AC power cord firmly into the grounded power
receptacle and into the printer. (Be sure the power source is
energized.)
Printer voltage is not
correct. Make sure line voltage is in the correct range. (See the
product label next to the power receptacle on the back of the
printer for voltage requirements.)
Blank or Garbled Control Panel Display
Check to see if... Solution
Printer is not turned on. Put the printer’s power switch in the on position.
Printer is turned on but
internal fans are not
running. Make sure the line voltage is correct for the printer’s power
configuration. (See the plate next to the power receptacle on
the back of your printer for voltage requirements.) If you are
using a power strip and its voltage is not within specification,
plug the printer directly into the power receptacle.
Display is blank and
internal fans are not
running. Press all the keys to see if one is stuck; contact your HP
service representative if this does not work.
