2 MAINTENANCE AND SUPPLIES
Replacing the Dry Ink (Toner) Cartridge
2-4
As you make copies, the dry ink (toner) will gradually be used up.
When it has reached a low level, the message, " Please replace
dry ink (toner) cartridge xx" will be displayed. The xx refers to
either yellow, magenta, cyan, or black dry ink (toner).
The 5750 can make about 40 to 50 copies after this message is
displayed. The number of copies depends on the size and color
areas of the originals.
Replace the indicated dry ink (toner) cartridge as soon as possible.
CAUTION: Do not use warm or hot water, or cleaning solvents, to
remove dry ink (toner) from your skin or clothing. This sets the dry
ink (toner) and makes it difficult to remove. If any dry ink (toner) gets
on your skin or clothing, use a brush to remove it, or blow it off, or
wash it off with cold water and mild soap.
To ensure your safety in operating the 5750, read the warning and
caution labels inside the printer/copier carefully.
