Summary: The product was great until I had to go replace the cartridges 2 weeks into use. I re-filled the cartridges instead of paying for the brand new HP cartridges (saved me 85%) but the indicator light signalling low ink wouldn't turn off even though there was plenty of ink in the cartridge. Support said that I had to buy the ink through them for it to work properly.
Summary: Comments about HP Officejet Pro L7780 Multifunction Printer: Scanner has very good quality. But whet you want to print a pdf it's like there's some parts missing. If you want to print something in normal paper in color the printer doesn't match the colors well.
Summary: Comments about HP Officejet Pro L7780 Multifunction Printer: I do like all in one printers but I chose this model specifically for its extra paper tray which you can use for any special printing you require done such as letter heading etc…and have locked so that it is not accidentally used. However with this model if you print a fax or copy a document it always prints from the locked tray and you waste the “special” paper.
Summary: I brought this printer for the features - duplex, extra tray, wireless, document feeder. The duplex works really good. The extra paper tray is worthless - is doesn't recognize the extra tray. Get scanner failure everytime I use the document feeder, which means can't fax, copy or scan more than 1 piece at a time. The machine is very noisy and loud. First time any problems with HP product.
