Lexmark W810 用户指南

The 

 message indicates that it is time to replace the items 

in the transfer kit:

The 

transfer roller

 transfers the image from the photoconductor 

drum onto the paper.

The 

ozone filter

 traps any minute amounts of ozone that can 

accumulate during the printing process.

Replace both items to ensure proper printer operation. Instructions for 
replacing them begin on page 131. 

After you’ve replaced the transfer roller and the ozone filter, follow the 
instructions beginning on page 139 to reset the printer’s internal counter 
for the transfer kit. This clears the 

 message from the 

printer operator panel display and ensures the printer alerts you when it is 
again time to replace these items.
