Downloading the new firmware from the HP Web site
For support information about downloading new firmware from the Web, go to
for the HP LaserJet 2410
HP
LaserJet 2420 printer, or
for the HP LaserJet 2430 printer.
The product can receive an .RFU update to the firmware when the product is in a READY state. The
product waits for all of the I/O channels to become idle before performing the update.
NOTE
If the firmware update involves a change in the format of nonvolatile random-access
memory (NVRAM), any menu settings that are changed from the default settings will return to
default settings. The settings must be changed again if you want them to be different from the
defaults. Examples of settings that are affected in this way are tray types, default symbol sets,
and Web-access alerts.
The elapsed time for an update depends on the I/O transfer time, as well as the time that it takes for
the product to reinitialize. The I/O transfer time depends on a number of things, including the speed
of the host computer that is sending the update and the I/O method (parallel or network). The
reinitialization time depends on the specific hardware configuration of the product, such as the
number of EIO devices installed, the presence of external paper-handling devices, and the amount of
memory that is installed.
If the remote firmware update process is interrupted before the firmware is downloaded (while
RECEIVING UPGRADE appears on the control-panel display), the firmware file must be sent again.
If power is lost during the flash dual inline memory module (DIMM) update (while PERFORMING
UPGRADE appears on the control-panel display), the update is interrupted and the message
RESEND UPGRADE appears (in English only) on the control-panel display. The update must now
be sent only by a computer that is attached to the parallel port of the product.
Finally, any print jobs that are ahead of the .RFU job in the queue are printed before the update is
processed.
