Digital BW, The Print

Hello all,

After years of work without any significant problems my printer got a 
serious clog. It was loaded by MIS UT7 inkset, when I discovered that 
I lost two nozzles (Cyan and Light Cyan) in the middle of page. 
Before that printout nozzle pattern was perfect. I didn't get nozzles 
back after number of cleaning cycles, then treating with Windex on 
the rest pad, then after loading two carts with MIS Fluid and doing 
cleaning cycles with it... I see some traces of clean liquid when I 
print purge pattern with cleaning fluid, but when I change back to 
ink, both nozzles are still clogged. Worst thing is that after 
cleaning cycles my other nozzles are going bad too.

Questions: is it possible that this part of pump that is doing 
suction is too dirty and makes things worse during cleaning cycle? If 
it is, could I clean it somehow? Is it possible to disassemble the 
thing and do a good cleaning of this pump? 
Is it possible that UT7 Cyan and Light Cyan turned bad after 2.5 
years in the bottle?

Thanks in advance,
Sergei

Regarding the pump, what I have had happen with large format printers is the
pump that pulls ink through the head in cleaning cycles fails.  I suppose
that same thing could happen with desktop units also.  Then the cleaning
cycles just don't do any good.

 

If you are using very old inks, the question might be whether you've
regularly agitated the bottles.  Pigments do settle.

 

You might try carts with Windex in them for a few hours at a time.

 

Good luck.
