# How do I set up the sipgate fax printer for Windows?
Step-by-step instructions for setting up the sipgate fax printer on Windows.
Sending faxes works not only via the sipgate web interface, but also directly on your device with the sipgate fax printer. Here you can[ download the 32-bit Windows version of the fax printer ](https://sipgate-faxdrucker.s3.eu-central-1.amazonaws.com/SipgateFaxdruckerInstall_x86.msi)and [download the 64-bit Windows version here](https://sipgate-faxdrucker.s3.eu-central-1.amazonaws.com/SipgateFaxdruckerInstall_x64.msi) download it and send faxes conveniently from your desktop from now on. With **Windows** you send faxes via the application **Print**.
**Important**: For Windows version 3.24, login no longer works due to an API shutdown. Please use the **fax printer version 4.3.3.1** from the **sipgate homepage** download.
➔ After you have downloaded the sipgate fax printer for Windows, follow the instructions of the **installation wizard**.
➔ After the program has been installed, you will find the **sipgate fax printer** automatically under your **configured printers**.
➔ To be able to send your documents as a fax, you must first log in with your sipgate credentials. To do this, press the key combination **Windows key + R** and enter the following path: C:\Program Files\SipgateFaxdrucker\SipgateFaxdrucker.exe and then press **OK**. The sipgate fax printer will now open — and you can log in in the browser.
➔ Now select the desired document and click the option **Print**. To start sending the fax, it is important that you select the **sipgate fax printer** as the printer.
Afterwards, the sending process and finally the successful transmission are displayed.
## **Frequently Asked Questions**
How can I improve the quality?
The source document should be black and white and without grayscale.
Can the fax printer be found in the Windows Store?
No, it is not planned for now.
Can the fax printer be installed on a Surface with an ARM CPU?
No, the fax printer only works with x86/x64 Intel/AMD CPUs
Why can't I see any contacts?
sipgate start login only has phone contacts
* when importing contacts via Google/CSV, make sure that phone/fax was imported
* close fax printer if open and restart via Print
* Fax contacts should now be loaded
* check contacts in the sipgate account and adjust phone->fax if necessary
* close fax printer if open and restart via Print
* Fax contacts should now be loaded
How can you send faxes faster?
\- send fax, wait until status "Document successfully transmitted"\
\- close fax printer "click X top right"\
\- document ➔ print ➔ sipgate fax printer send new fax\
\- check fax status in sipgate account ➔ event list\
from "Document successfully transmitted" the PDF file is on the sipgate server, which then faxes it; waiting in the fax printer is only necessary if you want to see the transmission status until the end
Is the upload of the temporary fax PDF encrypted?
From the fax printer to the web server, the data is transmitted encrypted via SSL port 443 using TLS 1.2.
**Possible error codes**
Below you will find a brief explanation of certain error codes
F400 “Transmission failed, please try again later (F400)
**F400 “Transmission failed, please try again later (F400)**\
**Log:** “failed to send fax: An error occured while sending the request”, when API is blocked after successful login in the fax printer\
**Cause 1:** Software firewall blocks requests from the fax printer to our API [https://api.sipgate.com](https://api.sipgate.com/) 217.10.72.56 and [https://login.sipgate.com](https://login.sipgate.com/) **or** general internet\
**Solution 1:** allow the fax printer to access the network/internet in the software/router firewall\
**Approach 1**: check C://Users/”Name”/AppData/Local/sipgateFaxdrucker/Logs to see whether/which error message with date and time matches the fax transmission\
**Cause 2:** sipgate has an outage, API does not respond\
**Solution 2:** Status page: check and wait\
**Problem 3:** Login works, fax connection loaded, error when sending (F400)\
**Log 3:** “Error: 0 : Failed! Response code was: GatewayTimeout” and “Warning: 400 : Sending failed: Api returned no sessionId”\
**Cause 3:** looks like api.sipgate.com cannot be reached\
**Solution 3:** check firewall rules to see whether api.sipgate.com / 217.10.72.56 is somehow temporarily blocked\\
Make sure you have an internet connection.\
\*\*Cause:\*\* when sending a fax there is no internet connection\
**Solution:** Check and repair the internet connection, then repeat the fax transmission

**Cause**: fax printer is uninstalled, there is only a renamed fax printer entry left\
**Solution**: Windows ➔ Printers ➔ delete renamed printer entry “Remove device”\
\- install fax printer, optionally change the name back to sipgate-fax printer
Error: print job ends up in the print queue / fax printer does not open (user)
**Error: print job ends up in the print queue / fax printer does not open (user)**\
**Analysis 1: Windows 10/11 + user**: fax printer starts as [process](https://github.com/sipgate/helpcenter-gitbook/tree/main/cloud-telefonanlage/.gitbook/assets/ProzessFaxdrucker.png) but not as user\
**Solution 1 Windows 10/11 user**: install fax printer 4.3.3.0\
**Workaround 1 Windows 10/11 + user**:\
\- cancel print job if present\
start C:/Program Files/sipgateFaxdrucker/sipgateFaxdrucker.exe, log in to sipgate, fax printer should now be logged in\
\- fax printer **close**, no entry of a fax number is possible here\
// starting once is necessary to obtain “user rights”\
\- Document->Print->Fax printer->Fax printer now opens, enter fax number\
\- manually restart sipgateFaxdrucker.exe when the user logs out or after PC restart\
**Analysis 2:** %LocalAppData%\sipgateFaxdrucker\Logs\
Log error: sipgateFaxdrucker Critical: 0 : error loading credentials: The array cannot be NULL\
**Problem 2: login data cannot be found/read:**\
C:\Users\Name\AppData\Local\sipgateFaxdrucker\config.dat\

**Solution 2:** unclear, check antivirus / firewall
Error: print job ends up in the print queue / fax printer does not open (Win Server)
**Error: print job ends up in the print queue / fax printer does not open (Win Server)**\
**Cause Windows 2016/2019 Server + WinPC user:**\
Redmon (Redirect Port Monitor) starts Faxdrucker.exe as user “SYSTEM” instead of local user, therefore you cannot see the fax printer GUI/dialog because there are not enough rights\
**Solution Windows 2016/2019 Server + Windows user:** install fax printer 4.3.3.0\
**Workaround Windows 2016/2019 Server:**\
(contact a server admin or system house for implementation)\
\- delete all sipgate fax printer registry entries if fax printer is already installed\
\- create a local admin\
\- perform fax printer installation with “local admin”\
\- log in as domain admin and set all rights under **Security** to domain user and SYSTEM\
\- local admin should now be deleted for security reasons\
\- fax printer starts; it needs 1-2 minutes on first start, after that it starts faster

**Cause 0**: software/hardware firewall blocks requests to api.sipgate.com\
**Solution 0**: allow software/hardware firewall access to api.sipgate.com\
**Example**.: Fritz Box->Internet->Filter->Lists->Blocked websites [edit](http://192.168.178.1/#/)-> api.sipgate.com\
**Example**.: Kaspersky->Settings->Protection->Firewall->Packet rules->custom rule that blocks api.sipgate.com / 217.10.72.56\
**Example**.: C:\Windows\System32\drivers\etc\hosts entry 127.0.0.1 api.sipgate.com\
\&#xNAN;**”Send fax” button is still grey / not clickable**\
**Cause 1:** not enough credit\
**Solution 1:** top up credit\
**Cause 2:** invalid fax number entered\
**Solution 2:** check whether fax number is entered correctly / no special characters\
\--> not possible 0137, 0138, 01212, 01807, 0185, 0181, 0188, 0900 as well as 118xx\
**Cause 3:** no fax port selected / possibly the user has no fax\
\- sipgate free has no WebFax --> the S/M/L tariff must be used\
**Solution 3:** Select fax connection, possibly switch to an S/M/L tariff\
**Cause 4:** unclear\
**Approach 4:** check C://Users/”Name”/AppData/Local/sipgateFaxdrucker/Logs / send to support\

**Cause**: you should not have zero credit or negative credit in the sipgate account\
**Note**: despite free minutes in the trial period, you have 0 € credit\
**Solution**: none, the fax printer can only be used with credit after the trial period\
**Different**: use WebFax, the WebFax in the customer area can use free minutes and credit
Error: fax printer login menu does not open after approx. 1 min “printed file is too large”
