Hi:
 
I have a very urgent problem with a DeskJet color printer 500c.
 
I have an exhibition next Sunday (we are expecting some 2000 visitors)
and the printer is out.  If I don't find what is wrong, I will have
to go to a store to find a printer, thus I would have limited tools
for last minute changes.  Just to say it is somewhat urgent.
 
 
I usually print with the Black ink cartridge.  But, I printed in
Color a lot of pictures 2 days ago.  Today, I decided to print
something in Black and put the previous black cartridge.  From that
moment, the Print Cartridge Lite (PCL) continously blinks to indicate
a wrong cartridge.  I changed the setting in Windows for the Black
cartridge.  PCL still blinking.  I put back the color cartridge.
Still blinking.  etc.  I exited Windows and tried to print
from DOS prompt.  No printing.
 
If I depress the reset button, the cartridge reaches its place.
But, the printer is not printing.  
 
Whenever I depress the cartridge button, the cartridge is moved from 
the center toward its location.  But, it stops, wait something, and
goes back to the center.  Looks like there is something that tells
the printer that the cartridge is not recognized.  
 
 
I cleaned the cartridge.  I tried the clean button.  I brushed
the electrical contact.  Nothing worked.
 
What can I do for an immediate repair?
 
Denis who is in a very bad position...
