Question about Canon PIXMA MP780 All-In-One InkJet Printer

1 Answer

Printing or faxing totally black pages

When I fax out, the receiver only receives a black page. When I try to copy, I get the same thing - a totally black page - whether I use the auto feed or on the glass.

In fax mode, I did a nozzle check and got the colors & black grid okay.

In copy mode, I did a nozzle check and got a dk gray/black page.

Why our fax sending and receiving solid black

Its a problem with scaner unit. Reports are being printed out, and do not pass trough scaner, because of thath report is Ok.

If the fax is still under warranty, go to warranty provider service.

Next time dont buy "kids toy" for fax machine. Try laser Canon Fax L140.

Our canon laser fax 1060p receives faxes fine but send out a total black page (also the copy function is a total black page)

No power/failed contact image sensor. If under contract get replaced. It is poss. that a "standard white setting adj." could fix it, but doubtful with a black copy. -Carl

My brother fax machine - only receives black pages

do a quick check on 2 things.
- Copy a document(put a printed page on document feeder and press Copy button) , has the Copy come ok? if copy is also blank that means toner/ink problem, needs to be replaced.

- check with your Fax receive Print settings. is any setting of econo mode/ contrast/brightness Off the track? If found any of such issue then Reset it or put it on average (middle).

Hope this will put your Brother on the track

Black page when copying and sending faxes.

You most likely have a bad SCANNER BLOCK. Not good!

Totally black transmissions

Copy lamp has blown, light should shine in where original is placed.... it isnt lighting the paper up, so reflection received is black hence black transmit/copy result

It is just a small specilised floro but would probally be more ecomomical to replace machine than to fix it.

Black pages when making a copy or printing something

Have you tried both drum and toner supplies? cause it sounds like a drum fault, if you have tried a new drum and toner, and it is doing it when printing internal reports, receiving fax's and copying then you have a tecnical issue to do with charge and this would likely render machine unecomical to repair (unless you can find a bad contact with drum on machine). If it receives faxs clearly but copys black then it is different issue (ie optics).
