Points to Note When Handling the Drum Cartridge and theToner Cartridges1) When setting a new toner cartridge (Y/M/C toner cartridge, black toner cartridge) inthe printer unit or if white spots occur on output prints because of uneven toner insidea cartridge, hold the cartridge horizontal and rotate it slowly up and down (about 45°)five to six times to even out the toner. (Instruct the user to observe this. In addition,inform the user that handling a toner cartridge other than the foregoing method cancause leakage of toner from the developing cylinder.)2) Remove all cartridges if the printer unit must be moved.In the case of the drum cartridge, put the special protective cover (MF4-0106-000)after taking it out of the printer unit, and put it in a protective bag or wrap it in a thickcloth to prevent exposure to light.3) Do not place the black toner cartridge near a CRT screen, disk drive, or floppy disks.The magnetic field it generates can damage the data.4) Do not expose the drum cartridge to direct sunshine or strong light. Doing so couldaffect print images.5) Do not touch the surface of the photosensitive drum of the drum cartridge.6) Do not place the cartridge on its side or turned over.
