Summary: I have used this printer in my home office for over two and half years. It is the best product I have purchased from Dell. There has been no jam or noise issue. The duplex module (purchased separately) works flawlessly. But most importantly, I can buy a whole set of compatible toner cartridges for $45 from Amazon. They work just as well as the the $300+/set OEM toners. This model has been replaced by the newer 2150CN.
Summary: I've had the Dell 2130c for over 2 months now and have been very happy with the printer and print results. I ordered and installed the duplexor separately. Installation is literally a snap because it simply snaps into place. It has performed flawlessly and I haven't had a single paper jam. I use 20 lb. general purpose copy paper and 24 lb. laser paper without any problems.
Summary: The reason I bought this printer is the availability of inexpensive replacement toner cartridges. I can buy replacement toner cartridges for less than half what it would cost me if I had an HP color laser printer. After using the printer for a week and being totally satisfied with it, I purchased the optional duplexer. The duplexer simply snaps into place and couldn't be easier to install. I've had the printer for about a month now and haven't had any problems with it.
Summary: I own the printer w/ duplexor and have run 2100 pages thru the unit with about 1000 of those duplex. The printer warms up fast and prints fast even when duplexing. The included drive works great over the network and has many cool feature such as the ability to print in booklet mode where the print driver re-organizes the print job so you can fold over an 8 1/2 x 11 page an make a booklet that is doublesided.
Summary: I really like the quality of the color on plain 28lb multipurpose paper. I do alot of basic printing B/W and color print and graphics and the quality of the color surprised me. I expected less than inkjet quality at 640dpi but instead I find the quality is better than my injet on plain paper. The speed and noise factor is another unexpected good surprise; noise is less than an inkjet and the speed of printing is 5 times or more faster.
