Any job needing white (post-maintenance recovery) on eufyMake E1

White often fails right after maintenance mode. A regular clean plus two failed test prints did not restore it. What worked: Deep Clean (~9 min) in EufyMake Studio PLUS removing and shaking the white cartridge, then another test print (~4–6 min). Needing 5–6 white layers or yellow/blue-tinted white is a sign white is not firing; healthy setup needs about 2 white layers on white or clear.
