Redistributing toner cartridge
When the toner cartridge is near the end of its life:
• White streaks and light printing occur.
• Toner Low  appears on the display.
•The  Status  LED blinks red.
If this happens, you can temporarily reestablish print quality by 
redistributing the remaining toner in the cartridge. In some cases, white 
streaks or light printing will still occur even after you have redistributed 
the toner.
1 Open the top cover.
2 Pull the toner cartridge out.
3 Thoroughly shake the cartridge 4 or 6 times to distribute the toner 
evenly inside the cartridge. 
Caution
• Avoid reaching too far into the printer. The fusing area may be 
hot.
• To prevent damage to the toner ca rtridge, do not expose it to 
light for more than a few minutes. Cover it with a piece of 
paper, if necessary. 
• Do not touch the green surface underside of the toner  cartridge. Use the handle on the cartridge to avoid touching 
this area.
4 Hold the toner cartridge by the handle and slowly insert the 
cartridge into the opening in the printer. 
Tabs on the sides of the cartridge and corresponding grooves 
within the printer will guide the ca rtridge into the correct position 
until it locks into place completely.
5 Close the top cover. Make sure th at the cover is securely closed.
Note
• If toner gets on your clothing, wipe it off with a dry cloth and 
wash clothing in cold water. Hot water sets toner into fabric.
