Hi artfulm,
Since the color ink is not being applied to paper after the deep cleanings the may be a issue with the color ink print head. Please be advised that the iP1600 was retired in 2011 and if you are using a refilled color ink, there may be a issue with the cartirge.
If there is a internal issue with the printer, service is not available since it has been retired. You do qualify for our Canon Upgrade program.
This is for out of warranty units which have been diagnosed to require service or are incompatible with a new or upgraded system. This program allows you the opportunity to purchase a replacement product discounted from the list price. We will also include free ground shipping with your purchase.
If you would like to take advantage of this offer, please call our Sales Department at (866) 443-8002 seven days a week, 8 AM to midnight EST
