Some days ago I had red drips on a print. It could have been the LM cartridge that was near empty or the head. I replaced both. Cleaned the heads and checked the head slots in the carriage. I doubt there was ink gathered there. Powered down, removed right side cartridges and took the right side cover off, I only need to remove 4 screws there as I did not place one back some years ago that is the most difficult to get at. With the cover removed and cartridges put in again and powered up you get much more view on the maintenance station. A head replacement order and the head carriage cover opened makes it easy to clean that black lid where ink is accumulated. With the wipers unit moving you can spray with a Windex bottle on the wipers and sponges, if needed a fast power down could halt the total movement. The wipers were quite clean. I noticed more red/magenta ink squirting on the black lid in the process and more of it on the wiper for that head, the printer probably cleaned that head more. Sponges were good but the MK one had more build up, not showing the sponge structure. Cleaned that one better and moistened it.
