Question about HP LaserJet 2420 Printer

49.4C02 Service Error

Our printer HP LaserJet 2420n was working great for nearly a year.  Then today, between print jobs, it went to this error (see subject) on the screen.  I called HP tech support since its still under warranty and spoke to someone NOT helpful.  Basically she said we had to update the firmware.  She faxed me cheat sheet on how to update this.  However, it claimed that when I put in the IP address of the printer into internet explorer, I would see a folder I would then drag a copy of an .RFU file (I had downloaded this per her instructions) into port1.  There was only a link to a port 1 but no folder.  Anyway, when I dragged this RFU file to this link, it would switch the window to a bunch of computer code.  Then she would have me turn off the printer and turn it back on.  It would look all normal, and say ready.  THEN, it would say "Processing job" and the data light would flash for about 30 seconds, then nothing happened and that was it.  It would give me that same Service error again.  She then had me pull out the printer's memory and put it back in and turn the printer back on.  Still didn't work.  And now when I power up the printer, it has a blank display screen (which means all my settings are lost!).  That's when she decided I needed the printer repaired and my options were 1. pay $69 to get a new one shipped to me and return this bad one or  2. Work with a local HP authorized repairman-FREE  or   3. Have them ship me a prepaid box, then send it back, and then wait for HP to fix it and eventually return it.  FREE  I have chosen option 2 and the repairman is coming tomorrow.  However, I may need to wait a week for parts! Any help to fix this sooner would be great as I need to get this back up and running...its our networked workhorse printer for my entire 6 person office.

    Thanks for trying!  That is what she was having me do when I called HP tech support, but that didn't seem to work per her instructions and frankly made things worse.  Hopefully the technician today can fix it.

The 49.4C02 error usually follows a paper jam. When the user closes a door after clearing the jammed media from one area of the printer, the control panel immediately posts a 49.4C02 error. Often, the customer will then power cycle the printer and it will hang at Checking Printer. For the 49 error to occur, additional media must still be stuck in the paper path.

Firmware version 5.005.3 contains a fix that allows the printer to recover and notify the customer of the location of the additional jammed media in the paper path. Customers who experience this issue should update to the newer firmware

I use a mac. I checked for jams. There were none. I powered off my printer. Turned it back on. Then went to my System Preferences and opened the print queue of my Printer. My printer was Paused. Deleted the files in my queue. Clicked Resume, then sent a new document to the printer and it printed just fine. I did this a few times with no more problems. I hope it's this simple for everyone else.

Porbably a font causing this. try change the printers resolution to 300 dpi. Make sure you clear any pending print jobs first to avoid the error when you cycle the power. the set 300 dpi in the printer's print quality settings.

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.

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.
NOTE If the error message
only appears when using
certain software programs,
contact the software program
vendor for assistance.

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.

Try to upgrade the firmware on the printer, if that error still occurs after the firmware upgrade, you should try and use PCL driver rather than PS driver.

Is HP Laser Jet 2420n


Duplex on this printer is manual, that means that you will have to re-insert the paper by yourself.

This if you have the 2420n, the 2420dn instead is the duplex model.

Here specifications, look where it says duplex, 2420n had only manual duplex (the printer wait for you to re-insert page).
