Our friends in Kentucky have been at it again, making changes to
older established products. This time it’s not printer firmware that’s
been changed but rather the construction of the cartridges used in
the Optra S, Optra Se3455, Optra T, T520/522 and T620/622 family of
printers.

The changes were made to the toner hopper section of these car-
tridges. The most significant change is that the angle of the doctor
bar has been altered. This results in a centered contact with the
developer roller rather than the offset contact found in the older
style cartridges. For the remanufacturer, this means that the trick of
flipping one-time-used doctor bars to get an unworn contact sur-
face, no longer works. Except for this, the changes appear to actual-
ly simplify the remanufacturing process rather than hinder it. As for
the reasoning behind the changes, they were most likely made to
eliminate lingering quality issues with the OEM cartridges, reduce
manufacturing costs and perhaps to even make the cartridges easi-
er to remanufacture for Lexmark’s own Return Cartridge Program
(formerly Prebate).

Though the changes Lexmark made to the Optra S style cartridges
relate only to the toner hopper, this How To article covers the entire
remanufacturing process.
