Error message 49.4c02 - HP 4700N Color Q7492AABA Laser Printer

SOURCE: 49 4C02 error

Well I was having the same problem. I cleaned out the queue by canceling the job that it was having the problem with. Turns out the data being sent to the printer was corrupt in this case.

SOURCE: problem with our printer 5200tn

From the Service Manual:

49.XXXXX ERROR
alternates with
To continue turn off then on
A critical firmware error has occurred that
caused the processor on the formatter to
abort operation. This type of error can be
caused by invalid print commands, corrupt
data, or invalid operations. In some cases,
electrical noise in the cable can corrupt data
during transmission to the printer. Other
causes include poor-quality parallel cable,
poor connections, or home-grown programs.
On rare occasions, the formatter is at fault
which typically appears as a 79 Service Error.

1. Turn the printer off and then on.
2. Press Stop to clear all print jobs from the printer memory.
3. Turn the printer off and then on.
4. Try printing a job using a different software program. If the job prints, try using the original software program to print a different job.

This error is typically due to some sort of data corruption. If this is happening on a single file, it could be that file. It could also be related to the individual software sending the print job, bad print commands or invalid. Although rare, a bad cable or connection can be to blame.

First step is to restart the printer, clear all jobs with the Stop button, restart printer again. Then try printing from another program, such as txt editor. If ok, then print a different file from original software, if ok, then print original file. 

If failure is with final print, the file is corrupted for printing, recreate file.
If failure is with original software see if there is any updates.
If failure is there directly after restart, try updating printer driver (this is not be a bad idea anyways).

If none of this works, it may well be a formatter board issue, requiring technical service.

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.
