Have you tested the telephone line to see if it has dial tone. Unplug the fax from the line and plug in a analogue phone to test this.While you are there check the extension number with the phone to make sure you are still on the same number. You can do this by dialing any phone with a display ie a mobile.

Unless I'm misunderstanding your question, your fax machine has nothing to do with the incoming fax number. That's assigned by your phone service provider to the telephone line the fax machine is connected to. The only way to change that number would be connect the machine to a different phone line. This might be as simple as just plugging the phone cord into another jack if that line already appears at a convenient location, or it might mean a visit from a technician to place a jack where it's needed. Or you can contact your phone service provider about assigning a new number.

I hope this has helped. If not, please post a comment with more information about your question and I'll try to help further.

Hello limay_uera

Please check your Printer setup. or options ( I am not familiar with this printer. what terms they use- I'm not sure) Ther will be options for Print in Color or Black. Make sure the radio button for COLOR is checked. This way, black and color both will print in the correct color. So leave it on color even when you want to print in Black. The black radio button is there for a different reason.
Hope this will help you.

You can set the unit to transfer the documents on to another fax. This is quite a longwinded process so I have included a link to the manual for this model as you will need to study this before you can achieve the transfer and my post would be running into several pages otherwise.

The link is here and the section you need to look at begins at page 141 on chapter 7-11

I realise you need to get these faxes out urgently so I am rushing my answer a bit!

In regards to the problem with the replace cartridge - I would recommend that when you get your faxes through you disconnect the machine from its power supply for 30 minutes then power up again to see if the issue resolves.

If not it is possible that the cartridge itself is faulty.

I hope this helps. Please do rate my answer. Many Thanks.

I'm not sure what you mean but if you are referring to a dual line then no. You cannot have two lines coming into the L800.

There is a cable that runs from the scanner to the processor. Looking from the front, its on the left side of the machine, on the back, it is a fairly large connector.
Unscrew the two thumb screws, then unplug it and plug it back in with the machine ON.
It will force it into a reset and may boot.

The problem is caused by a software glitch .

Check the tray settings and ensure that paper size guides are set to the appropriate paper size, then power off/power on the machine.

You probably have a dead low voltage power supply.

There might be a fuse on it, but a blown fuse usually indicates a bad power supply.
