Reliable. Had this unit for 5 years and it still keeps producing reliable copies. The fax function works well and the scan function connects to my computer without a hitch. I print about 300 pages a month, fax about 30 or 40 pages, and scan about 15 documents. For medium duty use it has been the most reliable machine I have owned.
What a workhorse. I have owned this all in one machine for over 5 years. It has never missed a beat. The quality of print, scanned items and fax resolution is great. I would say that it is also economical with respect to toner usage. I probably print about 100 pages per day. The version I have is not network capable, and it is not wireless, but my home network seems to be an okay work around. If I had a couple of wishes, I would wish that it were wireless and also wish that it opened up as a flatbed scanner (my work around is to tape to a sheet of paper and feed it through). This has been the best office purchase I have ever made.
