Question about Panasonic Panafax UF-780 Plain Paper Laser Fax

We have a Panasonic UF-4000 faxmachine. Faxes that we send are received very dark. We have changed teh Contract to Lighter, but that doesn't seem to help. Not all sent faxes have problems.

There is no computer adjustment for this..

what you need to do is lift up the front pannel and you will see to green handles , pull them towards the center and lift, it wont come out it will just come up a bit. if you see the toner cartridge you've gone to far. if you lifted it properly you will be able to tilt the white plastic and see a strip of glass. wipe that down with a cloth and try again. if its still doesnt work the cis might be broken

HOW DO I un-lock the scanner on a Brother MFC 7420?


Unfortunately, the MFC-7420 doesn't have a physical lock switch. You need to turn off the all-in-one and wait for the unit to clear its memory. If the error recurs after you press the power button again, wait 30 minutes and try again. (Note: you will lose any faxes that are in memory. See the User Guide page 11-5 to save this information.) You can find the manual on the Brother support page for the MFC-7420: https://www.brother-usa.com/support/ModelInfo.aspx?R3ModelID=MFC7420 . Click on the Manuals & Documents tab. Then click on the Manuals on our Online Solution Center for the English version of the manual. The direct link to the User Guide is currently: http://download.brother.com/welcome/doc000387/ALLFB_UsaEngUsr_B.pdf .

You can also try unplugging the all-in-one for several minutes to reset the error codes. If the error persists, contact Brother if the MFC-7420 is still under warranty (1 year). If it isn't under warranty, consider replacing the unit. The repair costs may be unreasonable.

I hope this helps.

Prinnter not printing but showing 'put custom in manual tray'


There is still a print job in the queue. Place a sheet so it prints or kill the job.


Open Printers and Faxes. Open printer. Highlight jobs and Right click > Cancel, or Documents > Cancel.
For those stubborn jobs, Right click My Computer > Manage. Choose Services and Applications > Services > Print Spooler. Right click and stop. Then start. This may have to be done from the Print Server if it's network printer. Contact IT to kill.

My fax wont work in my ricoh aficio 1515 mf??


Using the 1515 as a fax machine is a pretty simple procedure if everything works right. All you have to do is hook a working phone line up to the phone jack on the back of the copier (the one labeled LINE, not TEL).

Why won't the fax work? If it is giving you an error message, what is the message?

If you are not getting a dial tone when faxing, unplug the fax from the phone line and plug a working phone in, and see if the phone gets a dial tone. If it doesn't, there is a problem with your phone line.

You can also try plugging the fax machine into another phone line. If the fax works on that line, then there may be a problem with the first line.

Are you having problems sending faxes or receiving them, or both?
