The manuals etc are now most likely included in the CD provided with the printer. Most accessories are supplied like that now.
What real use is a paper manual except to take up shelf space and to be read once, or perhaps twice, in the whole life of the printer?
Peertinent setup instructions are given on the "folded up sheet", you can't really expect much more, can you?
If you really wanted, you could print out the manual for yourself using your new printer.
