Hi,

With winter approaching and indoor humidity levels dropping I'm 
anticipating an increased chance of clogging. I'm wodering what the 
ideal range would be  for controlling humidity around a 4800. Of 
course, this will eventualy be tested by trial and error but should I 
start with 50 to 60%? In the summer the humidity was considerably 
higher but I made no attempts to dehumidify as I was not running into 
problems so long as, at a minimum, I printed nozzle checks daily.

Thanks,

Rudy

Rudy:

My 4800 set up with matte black ink never clogs even when it of kept 
off for 30 to 45 days. The humidity in the printers environment is 
kept at 40 to 50% year round. The down side is that when printing on 
RC papers, using another 4800 with photo black, you run onto the out 
gassing problem with much longer drying times.

I don't know about the 4800, Rudy, but I think around 50 percent  
might be good for the location in which your paper is stored. I store  
mine in a closet which houses the water heater and think that might  
help a bit when the humidity goes up. And I also think I remember  
list subscribers from high elevations in the Southwestern U.S. saying  
some time ago that their inkjets did OK until the humidity got down  
to around 20 percent. But the inks and the printers and the papers  
have all changed since then. Still, I think I'd consider putting off  
running a humidifier and keeping some records until I noticed an  
apparently related problem.
