Can't fax The printer won't fax.  It sounds like the scanning device isn't working properly.  When attempting to fax, I receive an error message telling me to shut off the power, then to retry again.

May i know the computer operating system and do you receive any error messages while attempting to scan via Solution center?

A manual for this unit is available here.

When using HP Solution Center can you scan?

Hi dbraaten,
This sounds like there is a problem with the scanner assembly. Are you getting any error messages? Like scanner error 5? If so call hp tech support 1800 334 5144.

HP multi units are notorious for scanner failures. It is just a weak component in their machines. I have seen this time and time again. The only solution is to change the scanner out or purchase a different machine. Just keep in mind the notoriety HP has which failed scanners. If you want to venture into the replacement of the scanner the following website might have the product you are looking for. Otherwise, search around the net for a scanner assembly unit for the OJ7310. But, be prepared scanner units are not cheap.

The FAX machine received some FAXes while it was without paper. Make sure the FAX has paper and try printing the stored faxes or check in the fax menu if they can be cleared without printing.
Another problem may be that the FAX received not faxes but voice messages, retrieve and delete the messages and the error should be gone.

The L7580 is not meant to be set up as a scanning device on a network. This unit can only function properly as a USB connected device to have all the features work. Also, for the software to install with out problems, all other All in One software fro previous HP printers need to be removed. Once we did that and did clean install using USB only then did it work.

Hello,

 

I have seen your message stating that "Initialization failed - Unable to acquire TWAIN-compliant device" error is received when trying to connect USB-Parallel type to your Laptop.

 

Well,  Printer  Panasonic UF4100, recommends to use only " Printer/Scanner Interface as Bi-directional Parallel (IEEE1284) " means you need to use Parallel cable to connect Printer to the Computer/Notebook.  You may receive some communication error messages if you are using a  "PORT REPLICATOR CABLE"( USB TO PARALLEL connector).  The error message that you have received is related to the communication error. Futher, if you use same USB- Parallel cable for long time the Printer Hardware functionality might go bad, since Printer memory gets confused and will not read or detect the Cable , since it is not a cable to use  mentioned by Panasonic Manufacturer.

 

Let me tell you, general functionality of Printer like Printing would work even if you use USB-Parallel cable. But it is not a case with Scanner and Fax functionality.

 

Hence, I recommend you to use only Parallel cable to connect your Printer to the Laptops.

 

I hope that this will resolve the issue for you.

 

You can email me at [email protected] if you need further assistance.

 

Bye.
