So far few paper jams with the auto document feeder; print resolution is good for text; physically refilling the starter ink cartridge supplied was not completely successful, however, an original HP replacement cartridge (£16 for the extra capacity black) was refillable easily using a syringe/ink kit cheaply available elsewhere.
The machine works nicely as a standalone fax, copier (copying - which is slow- using black ink only IS an option unlike some HP all in ones,) HOWEVER, forget about one touch scanning: the custom software suite required for this, is very badly programmed and will use up all of your processor power; therefore, realistically, scanning requires using the scanner wizard built into Windows (click " scanners " in the "control panel" to access this), or, using "paint", both of which give the option of scanning from the platen or from the automatic feeder (as well as a few other useful options such as greyscale, custom resolution, etc). My memory being faint, use of said basic applications may require the "basic scanner driver" for this scanner, downloadable from the HP website.
Likewise, forget about "advanced functions", such as checking the ink level, and other things provided by the "software suite", because you really do not want it installed on your computer, at all, trust me.
It is very cheaply built. However, having paid for this unit, barely more than the cost of a cheap printer, I am delighted with it.
