Question about HP Office Equipment & Supplies

A critical firmware error has occurred.
Turn the device off and then on.
2. Try to determine whether the error
occurs intermittently, while printing, or
when turning on the device.
3. If the error appears while printing,
determine whether it occurs when
printing from a specific computer, a
specific application, or a specific file. If
all other computers, applications, or files
can print without the error, then the
problem may be only within one print job
or computer. Make sure the computer
has the most current printer drivers, or
use a generic printer driver.

Click Download Drivers and
Software. Check for the latest firmware
image version at the bottom of the page.
If this firmware image is newer than the
one installed on the device and the
device can receive a firmware update,
download the newer firmware upgrade.

software program. If the job prints, go
back to the first program and try printing
a different file. If the message appears
only with a certain software program or
print job, contact the software vendor for

49 and 79 Errors, Turn off then on
The product has experienced an internal embedded software error.
Turn off the power by using the power switch, wait at least 30 seconds, and then turn on the power and wait for the product to initialize.
If you have recently installed a memory DIMM in the product, turn off the product, remove the memory DIMM, reinstall the DIMM to verify that it is seated properly, and then turn on the product.
If the error persists, contact HP. See www.hp.com/support/LJM2727 or the support flyer that came in the product box.

a 49.xxxx error on an HP means that there is an issue with one or more hard disks. you can try to re-initialise the hard disk(s) by rebooting the printer while holding the green button. when the three leds are lit, release the green button, and navigate using the numerical buttons until you see "initialise hard disks" on the display of the printer. confirm by pressing the green button again. if all goes well, your printer will take two minutes longer than usual to boot. if you still get the same error afterwards, you need to replace the disk.
