How to use

Power the printer back on and allow any initialization or calibration routines to complete before starting normal printing.

Usage recommendations

For consistent results, use the drum unit with compatible high-quality toner cartridges and follow periodic printer maintenance such as cleaning the paper feed and internal rollers. Store spare drum units in a cool, dry place away from direct sunlight to preserve performance. Monitor print output for signs of wear such as streaking or uneven density and replace the drum unit when print quality degrades.
