    This has been popping up every other day now. It's either the magenta or cyan. I'll print some jobs, sheet cut, start the same job and a color has dropped out. A few med cleanings brings it back 100%. Eco-Sol Max Carts are full. This is a VS-640. Only other issue is it can't print a deep red at all. Even though all nozzles fire, a good red just eludes it. :-(

    -has this been a chronic issue, only recently happening more frequently?
    -anything out of the ordinary lately, like service-work or head crashes?

    ink supply is usually the culprit, either air in the system or something inhibiting the flow.
    You can always rule out electrical/printhead issue if you do a data-swap, but my best guesses would be: a near-empty ink cart, airbubbles in ink line or printhead, a bad damper/seal, cracked printhead manifold (plastic tip that connects printhead to damper), or the capping station not always making a proper seal (either ink build-up or warped).
