My 4900 sat for a while and this time the Windex solution and cleaning cycles are not working.
Initially Magenta and Cyan were blank. After some cleaning cycles I got half of Magenta to print, but still no Cyan. Other colors were mostly fine, except LLK missing 30%.
After another Windex soak I did a nozzle check and got half of cyan and still only half of Magenta. From the printer menu I did two powerful paired cleanings on C/VM, which resulted in Magenta disappearing altogether.
About ten windex treatments later I got all of Cyan back but still no Magenta.
A magenta flush image printed through QTR RIP calibration mode printed blank. LLK showed some banding.
Did some more windex. Now all the colors are missing 50% or more. Magenta still blank.
Can you explain this behavior? (I was regularly asked this question as a child, btw.)
It seems the obvious next step is to get a set of cartridges and Piezoflush, do an INIT FILL through the service program and see what happens. Is that right?
When I was only dealing with Magenta being blank I wondered if I could get by with a single channel flush, but that question seems moot, now.
Should I continue to Windex? I read in another post someone having success filling cartridges with Windex and flushing the heads. I mention this because I’m overseas and it’s either costly or time consuming or both to receive shipments internationally, so workarounds are often necessary.
One more question. I know where the time goes but not where the ink goes when it’s sent to a fully clogged head. Does it go into the maintenance tank or nowhere at all?
