Usually the wiper blade at the capping station that isn't 
effective. Clean it + the capping station, both with Windex 
and dry the blade with a small cloth. Check the rubber edge, 
look for a sharp edge and abrasion marks. Replace it if it is 
not sharp or has ragged edges. ( I once got a "refurbished" 
9000 that had the wiper blade reverse mounted so the felt side 
had to wipe the head, didn't work :-)  Check the rubber edges 
around the sponges in the capping station. Remove any paper 
lint. Check whether that wiper blade goes still up down, the 
same for the capping station.  Windex will clean the mechanism 
as well. Vacuum clean the surrounding area so no new paper 
lint can get in. Do a capping station alignment.

Better clean the head as well. Found a new method that's 
easier and better than the wet cloth etc. At the left side of 
the 9000/9500 is a kind of rectangular spitting hole. Cut a 
sponge so it can be inserted in that hole but sticks out 
approx 1/4 inch. That can soak more windex/warm water and is 
flexible enough not to harm the nozzle surfaces. Size has to 
be about 65 mm long, 14 mm wide, 30 mm high. The head can be 
moved over the sponge and the dirt will be soaked and get in 
the sponge. There may be some water + ink on the printer but 
it can be cleaned easily and it is outside the paper transport 
area. The head can be parked again and a cleaning done to wipe 
the surface again. Remove the sponge and clean it for the next 
time.  Making a  kind of toothbrush surface on the sponge and 
also add an extra rim at the top to take away the dirt that 
accumulates around the edge at the top of the head (usually 
offsetting dirt to the grey paper pressure rolls) would make 
an even better washer sponge.  So far I take that dirt off 
with a soaked shoe lace.
