Firs, yes the T630 will contain most of the information you are looking for. Obviously, it will not cover the features of the T640.

Did you check the downloads section on www.lexmark.com For the publication you need.

Lexmark t640 error message


"Remanufactured cartridges" How do you define that?

Given that Lexmark does not support or condone the use of third party products in their printers.

When a cartridge is new from the factory, all of the components inside the cartridge are new.

When Lexmark sell a recycled cartridge, all of the components within the cartridge are ETN components (Equivalent to new).

That means all of the rollers have been change and the PC is new.

It seems you purchased a cartridge which has a defect.

Return it to your point of sale and see what happens with the next one.
