The LaserPrinter
4111 does not require much care and maintenance.
How-
ever, it is important to perform a few cleaning tasks to maintain your printer
in good condition. This chapter will explains procedures for replacing the
EP-L cartridge, handling the EP-L cartridge and printer, and cleaning the
printer.
7.1 REPLACING THE EP-L CARTRIDGE
Replace the EP-L cartridge in the following cases:
l
If print quality is still low, even after you have redistributed the toner by
removing the cartridge and rocking it gently from end to end about five or
six times.
l
If transparency films show stain problem at either the top or bottom of the
films.
NOTE: For directions on replacing the EP-L cartridge, refer to "2.2 Install-
ing the EP-L cartridge".
7.2 STORAGE AND HANDLING PRECAUTIONS
FOR THE EP-L CARTRIDGE
The EP-L cartridge contains both the photosensitive
drum and toner used for
printing. Since the drum is extremely
sensitive to the light, it may be
permanently
damaged if it is exposed to the direct sunlight or strong light.
Caked or unevenly
distributed
toner may result in poor print quality.
Therefore,
always observe the following rules:
l
Always keep the EP-L cartridge in the aluminum bag in which it was
originally packed. And do not open the bag until you are ready to install
it in the printer.
