Panasonic UG-3221 Toner Cartridge

Paper jam? The best way to remove jammed paper is to gently pull the paper in the direction of the paper path - with power off, of course. Do not pull the paper backwards - you could damage your printer forever by doing so.

Are you getting diminished color and print quality? If all your images start to look a bit purple, blue or orange, one of your ink wells may be running low. Replace the whole printer ink cartridge, unless you can refill the individual ink wells.

If debris is the primary cause of failures, toner is the primary cause of debris. All toner cartridges release a small amount of toner powder into the machine. This is why it's important to clean the machine when you change the cartridge.
