Prepare just annoyance and frustration!

Purchasing this inexpensive device itself I very regret. I tried all sorts of paper types, but always the same problem: He draws daily new two sheets simultaneously, no matter how many times I roll the paper to be over the thumb. But what most brings me up the wall and now leads that I dispose of the thing professionally is the fact that suddenly no pressure in black done more. I tried everything, cleaned, paged printed diagnoses and therefore the newly inserted, original HP cartridges leergedüst again to a quarter, but black it does not print still, even after repeated printhead cleaning and re-cartridge replacement.
HP - No, thanks, I've had enough.

Update 07/17/2015: Now he is finally disposed of, he also did not want to scan, allegedly no connection to the PC, which is definitely not true. Have rumbasteln abandoned after three hours, now an Epson must be proved.
