Default Brother MFC-890 and "PLS OPEN COVER"

Dear people,

I have a Brother MFC-890 multi-function machine (you know - printer,
copier, scanner, faxer, and digital picture printer).

It's been absolutely fine for about a year. (Yeah, the warranty
year.)

But all of a sudden now, when trying to print out Christmas cards
(based on a jpeg in Paint Shop Pro) it has gone hooey. It now has a
problem with printing big images. (It's not only from Paint Shop Pro.)
It still prints texts without problems.

Hmmm a trifle irritating to say the least.
What is supposed to happen is when you open the cover and close it again you
will get a machine error code that indicates what went wrong, or you will get
no code which means the error was transient and went away. Helpful eh?
What is probably happening is there has been a transient error.
If you go to maintenance mode and enter function 80 you should get a display of
the machine log, that may hopefully give you some machine error messages if it
does then post them here and I will try to translate for you.

I had a different Brother MFC (cost me $400). Almost exactly a month
after it went out of warranty--and immediately after spending 0ver $50
on expendables) it started a routine much like the OP's. In my case, it
was a paper feed error, which wouldn't allow the machine to
initialize--rendering ALL of the functions (fax, printer, scanner,
copier, fax modem)--inoperative. It would tell me one error, I'd clear
that one, it would crank through part of it's routine and give me another.

I opened it up against the advice of a few here, and discovered for
myself what many had told me: it was a nightmare to repair. I never did
discover the exact cause, although I suspected a sensor problem...junk POS.

I tossed it and got an HP...lots easier to service.....
