Sending fax to network fax-printer

Hi,

I have the RICOH Aficio 2018D device which can be used to send fax. It is installed as a network fax-printer in my LAN. I want to write an application that will send faxes using this device. Can I use the FAXCOMLib for this purpose or it is only for fax-modems?

I tried to use it. The code was:

FaxServer faxServer = new FaxServerClass();
faxServer.Connect("MICHAELB2"); // It's my PC's hostname
FaxDoc doc = (FaxDoc)faxServer.CreateDocument(@"C:\Dmitryp\FAX.NET\test.doc");
doc.FaxNumber = "12345678";
doc.RecipientName = "Me";
doc.Send();
faxServer.Disconnect();

This throws the COM exception on line "doc.Send();". The exception is:
"The object identifier does not represent a valid object. (Exception from HRESULT: 0x800710D8)"

Well, I tried to pass the fax-printer hostname to Connect() method, but then I god another exception, again on the same line "doc.Send();":
"The handle is invalid. (Exception from HRESULT: 0x80070006 (E_HANDLE))"

Any ideas?

Hi Dmitry,

I also need to fax from visual basic to network fax printer.
Have you found any way to do this?

Thanks in advance.

Is the type FaxServer an interface or a base class?

Also, did you try the fully qualified name for your computer (e.g., including the domain name)?

I think if you successfully connect to the fax server, it'll go a lot further. . .

Did any of you guys find a solution for this , i get into the same issue


here is the code that im using
FaxServerClass fs = new FaxServerClass();
fs.Connect("XXXXX"); //specifies the machinename

object obj = fs.CreateDocument(file);
FaxDoc fd = (FaxDoc)obj;
fd.FaxNumber = "XXXXXXXXXXX";//will be replaced with the proper fax number
fd.RecipientName = "Tester";
fd.Send();
fs.Disconnect();

The error that i get is

System.Runtime.InteropServices.COMException was unhandled

Caveat: I've never tired this before.

This post (link; see accepted solution) say the key parameters to set are FileName and FaxNumber... So maybe you should modify your code to be like:

Code:

---

FaxServerClass fs = new FaxServerClass();
fs.Connect("XXXXX"); //specifies the machinename

object obj = fs.CreateDocument(file);
FaxDoc fd = (FaxDoc)obj;
fd.FaxNumber = "XXXXXXXXXXX";//will be replaced with the proper fax number
fd.RecipientName = "Tester";
fd.FileName = //you fill it in;
fd.Send();
fs.Disconnect();

---

Like I said though, I've not done that before.
