Introduction
In addition to using the correct paper and feeding it properly, the
proper application of print onto paper requires that the EP-L toner
application systems run smoothly. This chapter explains basic
maintenance tasks to keep your printer running smoothly. It
includes how to install an EP-L toner cartridge, how to produce a
cleaning sheet, and how to handle the printer if you need to move
it.
When to Replace the EP-L Cartridge
Usually, the EP-L cartridge lasts for approximately 3,500 prints
(estimated for an average of 5% coverage on letter size paper).
When the cartridge toner supply gets low, some parts of the page
print lighter or don’t print at all. You may sometimes increase the
life of the EP-L cartridge by taking it out of the printer and
redistributing the toner (fig. 6.4). Follow removal and installation
instructions as normal, except re-install the existing cartridge after
distributing the toner.
The EP-L cartridge contains the toner and laser-sensitive drum
needed to operate the laser printer. The EP-L cartridge
■ Is sensitive to light. Do not expose it to direct sunlight after
opening
■ Should be installed immediately after opening
■
Should be kept level for storage. Do not stand or store the
cartridge on its end.
■ Contains a magnet. Keep the cartridge away from CRT’s,
disk drives, and floppy disks since possible damage to data
stored in these devices may occur.
