Adding fuser shield
When directed by a message, add fuser lubricant as soon as
possible. If it is not added, the printer stops after approximately
5,000 prints and not run until fuser shield is added. Please read
the important note below.
NOTE: In 2006, the formula for the DocuTech HLC fuser lubricant
was changed to provide better image quality and to prevent image
transfer. The new fuser formula is called Fuser Shield. The fuser
blend and the fuser shield CANNOT be intermixed in a DocuTech
HLC. To change from one fuser lubricant to another requires a
service call and cleaning or replacing components. The two fuser
formulas are identified with different color bottles and caps. Be
sure the color of the cap of the bottle you are filing from matches
the color of the cap already in the system. Fuser shield

when working in this area.
