WHAT IS A CODE J44

Dear
If you are sending the fax using ADF, there may be the document jam, Open the ADF cover check the path for any foreign objects.
Also you can send from platen glass without document jam.

Also this may happen to the other end fax machine, better you do a test copy from ADF and Platen glass. and confirm your fax machine is ok.
Thanks.

I went online and found the HP8600 user manual and this is their solution to the error code 363 that you reported, which I copied off their site. Hope this works for you:

• Turn Error Correction Mode (ECM) off, if you encounter the same error repeatedly. Click this link HP All-in-One and Fax Products for more information on enabling or disabling ECM.
  

  
  

  NOTE: Error codes that apply specifically to ECM have ECM listed next to them.
  

  
  

Error Code: 356, 357, 358, 359, 360, 361, 362 ECM, 363 ECM, 364 ECM, 365 ECM, 366 ECM

Definitions

• The remote user pressed the Stop key, causing the session to be terminated.
• The remote machine encountered a system problem such as no paper or a paper jam. This prevented the fax from receiving any more pages, and caused it to terminate the session prematurely.
• The call-waiting service can cause this error. The click, heard for an incoming call, is actually a momentary disconnect of the line.
• The remote machine encountered an incompatible feature causing it to terminate the session.

Solutions

• Configure the remote machine for document reception by clearing any paper jams, loading sufficient paper, and clearing any other error messages.
• Configure the local fax machine to use a slower reception speed.
• Enable or disable the ECM setting.

Hello
This the method to clear paper jam, follow these steps:-
Turn the printer off and on to see if it can automatically clear some or all of the jam. Many printers provide an error-code listing on the front panel display for the area where the jam occurred. If your printer shows an error code, be sure and check the printer manual to see if that identifies the area of the printer where the jam occurred.
Turn off the printer.
Remove any paper trays. Inspect them for wrinkled or damaged paper.
Open any other doors that give access to the printer's paper path and to the ink cartridge. 5 If necessary, remove the ink cartridge. Place it in a bag or away from light to avoid damaging it.
If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though.
Replace the ink cartridge and paper trays, close any doors you opened and turn the printer back on.
If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
Good Luck

When you removed paper from the machine, did it rip at all? If it did, a small scrap could have been left behind, causing the jam code. Depending on where the machine is located and who uses it, there might also be a foreign object lodged in it (like a staple or paper clip). If you think there is nothing in there causing the jam, try turning the machine off and turning it back on, and see if it still shows the jam.

Error code 322- There was a communication error with the receiving fax machine due to poor telephone line conditions.
Solution
Set the receiving machine to receive at a slower transmission speed
If the session fails after sending several pages of a large document, resend the document as several smaller documents.
Retry the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
Error code 358--
The remote user pressed the Stop key,
The remote machine encountered a system problem such as no paper or a paper jam.
Try
Configure the local fax machine to use a slower reception speed.
Disable ECM mode on your machine.
Try sending a fax to another location.

My KX-FT73CX Fax always Paper jam when turn the machine

HP Officejet 7210 All-In-One InkJet Printer
Error code: 405

When I send a fax I have a dial tone and the fax feeds through, I hear the other end answer it says it is sending and then I get the printed page that says: "A communication error occurred during the fax transmission."
