Troubleshooting
View all →Common Failure Modes
Liquid ink cartridges dry out and clog printheads if not used weekly. Toner does not dry out but can suffer from drum scratches causing vertical lines.
Maintenance
View all →Print Weekly (Ink)
Liquid ink dries in the nozzles if idle. Printing a test page prevents clogging.
Shake Toner
Toner powder settles. Shaking the cartridge redistributes it and fixes faded streaks.
