Several things can cause that, but it looks like the head is drying out (air getting at it).
If it improves after a couple heavy cleaning cycles or use it's most likely cap top not sealing properly allowing air to get at the heads. Either bad, or not adjusted to seal the head when it's parked.
I'd start by soaking the heads before they get too dried out, and replace the cap top.

Other things that can cause that are plugged/ kinked/ damaged line between cap top and pump, or pump is going out. None are really major high dollar repairs.

captop not seating against the head?
FIRST take a syringe and saturate the felt with cleaning fluid (ink with no pigment)
run a cleaning cycle, REPEAT a time or two

wouldn't hurt to pull ink through the line from captop to pump for waste tank
