TECHNICAL TIPS
On this type of cartridges, the developer roller seal cover should always be
installed in order to protect the exposed developer rollers during
transportation, it will also help avoid leaks and it will give cartridges an OEM
finish.

You will save money when utilizing a developer roller seal covers on your
remanufactured cartridges by increasing the percentage of empties with good
developer rollers that are very expensive and in some cases not even available
as an aftermarket replacement part. You can provide end users with instruction
on how to install them and request that they return the empty cartridges.
