Hello,

I recently spent most of a day trying to get my previously working 
printer to print. Windows kept saying that it wasn't connected. [there 
aren't any Linux drivers for it so I have to use Windows to print] I 
tried everything I could think of, then went online to the Lexmark web 
site to see if I could find any answers.

While there I found they had live chat support, so I tried that as I was 
out of ideas. The tech ran me through a bunch of tests, and then began 
trying to have me adjust the thin plastic ribbon that runs behind the 
ink cartridges, and telling me that it had slipped out of it's little 
clips on the back of the ink cartridge carrier.

The problem was that the cartridge carrier always moved over to the 
extreme left end of the carriage as soon as the printer would be turned 
on, and then the power button would begin flashing, and Windows would 
complain about no connection to the printer.

I finally gave up on the chat support, and looked around the Lexmark 
site for answers again. I finally found a pdf file for my specific model 
of printer. [the tech had kept referring me to docs that applied to 
other models, insisting that my problem was similar to these]

After reading it for a while, I finally focused on a short notice about 
two cases of flashing power button, one slow flashing, and the other 
fast flashing. It turns out that if the power button flashes slowly, the 
printer thinks it is out of paper. There was what I thought was an 
adequate amount of paper already in the sheet feeder, but out of 
desperation I loaded more paper in, and the printer began working!

The only problem I had with the printer after all that strife, was there 
wasn't enough paper in the sheet feeder for the printer to detect it. 
You may indeed have a more complex problem, but it never hurts to try 
the simple stuff first. 8-)

Later, Ray Parrish
