Firmware error when printing. Solution? - HP LASERJET P1006 Printer

Problem :
For errors 2618, 2F48, 2F49, 2F50, 2F51, 2F52 randomly occurring please follow the steps below.

Solution :
If the printer has the latest firmware installed (Ver. 1.25 or higher - iPF8300 Series), you only need to do the following:

1. Check if the Status Print or Print INF files indicate which print head experienced the error and replace it.
2. If the specific print head failure cannot be determined, replace both print heads.
NOTE: With the previous low level firmware installed, any printhead damage may have spread to other components. Upgrading to the latest firmware version prevents the other components from being damaged in the future. For the initial failures with the low level firmware, you must replace the other components that would have also failed.

#The error might be caused by a
network connectivity problem,
such as a bad interface cable, a
bad USB port, or an invalid network
configuration setting.
#The error might be caused by the
print job, such as an invalid printer
driver, a problem with the software
application, or a problem with the
file you are printing.
#Upgrading the product firmware
might help resolve the error. See
the product user guide for more
information.
For upgrading the Firmware. go to hp.com, download the firmware, read the read me file before uploading the firmware...

49.XXXXX ERROR
alternates with
To continue turn off then on

A critical firmware error has occurred.

1. Press CANCEL JOB to clear the
print job from the printer
memory.
2. Turn the printer off, and then
turn the printer on again.
3. Go to http: www.hp.com/
support/lj2420.
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
printer and the printer can
receive a firmware update,
download the newer firmware
upgrade. Not all printer
models can receive firmware
upgrades.
4. Try printing a job from a
different 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 assistance.

If the message persists, try this:


1. After performing the actions
listed in the preceding item, if
the message persists when
using different software
programs and attempting
specific print jobs, disconnect
all cables that connect the
printer to the network or a
computer.
2. Turn the printer off.
3. Remove all memory DIMMs
or third-party DIMMs from the
printer. (Do not remove the
firmware DIMM in slot J1.)
4. Remove all of the
EIO devices from the printer.
5. Turn the printer on.
6. If the error message
disappears, reinstall
each DIMM and EIO device
individually, making sure to
turn the printer off and then
on again as you install each
device. To replace a DIMM,
see.
7. Replace the DIMM or
EIO device that caused the
error message.
8. Remember to reconnect all of
the cables that connect the
printer to the network or
computer.
9. If this error message persists,
replace the firmware DIMM.
10. Replace the formatter

49.XXXXX ERROR
A critical firmware error has occurred.
1. 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.
4. Go to www.hp.com/support/LJP3005. 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.
Try printing a job from a different 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 assistance.
6. If the message persists, contact your HP Support.

This is what the result for that error code is:-
ERROR 49.XXXX
A critical firmware error has occurred that caused the processor on the formatter to abort the operation. This type of error can be caused by invalid print commands, corrupt data, or invalid operations. In some instances, electrical noise in the cable can corrupt data during transmission to the printer. Other causes include poor quality parallel cables, poor connections, or specific software programs. Remove all EIO devices and firmware DIMM if installed. Restart printer. If error is gone replace each EIO device until error appears. Replace device which triggers error. May also be formatter.
Firmware updates are available for some machines at http://hp.com and clicking on the drivers and software tab. Also try printing from a different application. If that works go back to the first application and try printing a different file to determine if the problem is file related. You may need to reseat the memory DIMM's or replace the firmware DIMM or formatter board.

From the service manual:

A critical firmware error has occurred that caused the processor on the formatter to abort the operation.
This type of error can be caused by invalid print commands, corrupt data, or invalid operations.
In some instances, electrical noise in the cable can corrupt data during transmission to the printer. Other causes include poor quality parallel cables, poor connections, or specific software programs.
Sometimes, the formatter itself is at fault, which is usually indicated by a 79 Service Error.

Recommended action:

1 Press CANCEL JOB to clear the print job from the printer memory.
2 Turn the printer off and then on.
3 Go to www.hp.com/go/lj4300_software, Select 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 printer and the printer can receive a firmware update, download the newer firmware

6 Turn the printer off.
7 Remove all memory DIMMs or thirdparty DIMMs from the printer. (Do not remove the firmware DIMM in slot J1.)
8 Remove all of the EIO devices from the printer.

After performing the actions above, procede with the following:
1 Turn the printer on.
2 If the error message disappears, reinstall each DIMM and EIO device individually, making sure to turn the printer power off and then on again as you install each device.
3 Replace the DIMM or EIO device that caused the error message.
4 Remember to reconnect all of the cables that connect the printer to the network or computer.
5 If this error message persists, replace the firmware DIMM.
6 Replace the formatter assembly.
