Digital BW, The Print

Hi guys,

Well, first off, this forum has a good reputation and was recommended by another forum on printing issues.  So, just to encourage you all.

I have recently bought a CISS system for my canon pixma ip4000 (which is a great printer and I love and I'm never getting rid of).  I am having big problems printing the colours.  When I first installed it, I printed out a black and white text documment of significant length.  Ever since then, my black works great.  If I do a cleaning cycle on the printer, and then print anything with colour, it works great.  But once left overnight, some colours wont print properly.  At the moment it is yellow.  I can easily clean the print heads again and use the printer for today and it will print fine, but I can guarantee in a day or two one of the colours wont print.

For example, I have just done one cleaning cycle, and done a nozzle check and they are all printing perfectly.  But tomorrow, or the next day it won't be like that. 

I am wondering if the reservoir tanks need to be raised just a tiny bit to help with the gravity feed.  

Your help will be much appreciated!

Thanks guys,

Me

Is the humidity especially low where your printer is located?

Yes, I find the ink level in the tanks should be just above the print heads.  These systems can syphon the ink back into the tanks if the ink level is lower there.
