This seems like a dumb question, but it's an annoyance...
I have difficulty determining ink levels in my 3880 cartridges without removing the cartridges.
On one cartridge in particular, PK, a slip-up during the initial fill resulted in ink being sucked up every joint via capillary action and slight discoloration of the cartridge in general. Despite attempts to clean / wash it off after the initial spill, it is difficult to determine the ink level even with the cartridge removed.
Is there any particular place to view the carts for ink level without removing from the printer that works better than others?
Is there a recommended way to clean the outside of a cart (long after the ink has dried) for better viewing of the ink level?
How often should carts be removed and shaken for proper ink suspension -- once a week? month?
I've tried not to do it often out of concern for damaging the ports.
