Supplies
The customer replaces print cartridges, the fuser, and the transfer unit as they are depleted.
Chapter 4 explains when to replace supplies and provides instructions on replacing them.
NOTE
The printer tracks the amount of use on the customer-replaceable supplies by keeping a
page count. Swapping supplies between printers might cause a misrepresentation of supply
life values and is not recommended.
If you replace either the fuser or the transfer unit when servicing the printer, and these
supplies have not yet reached the end of their estimated life, you must reset the page count
for these supplies through the CONFIGURE DEVICE menu on the control panel. See
Fuser
replacement configuration and Transfer unit (ITB assembly) replacement configuration for
instructions on resetting the transfer unit and fuser counts.
