CAUTION: For best results, use Dell toner cartridges. Print quality and printer reliability are
not guaranteed if you do not use Dell supplies.
To replace the toner cartridge:
1. Open the front cover.
2. Pull the used toner cartridge out and lift it up and away from the printer.
CAUTION: Avoid reaching too far into the printer. The fusing area may be hot.
3. Unpack a new toner cartridge. Hold the cartridge carefully and gently shake it from side-to-side 5 or 6
times to distribute the toner.
