Summary: I got tired of inkjet printer problems so bought this B1260dn after doing a lot of research. I only print a few pages a day, sometimes nothing for several days, very light duty. It has printed 50+ sheets at a time on several occasions without fault. It's still going strong after 7 months and delivers clean copies even with the light use. I leave it in sleep mode so it wakes quickly and delivers every time. I also own 4 Dell laptops that have never failed either.
Summary: Works OK for small print jobs. Good speed & clear printing. I tried to print a 150 page file in duplex mode and found that the paper, after the first pass was very hot and distorted (warped from left to right). I fanned the paper to dissipate any static, straightened the stack and placed it back in the input tray. After restarting to print the second side, I noticed that several sheets were being double fed. About 3/4 of the way through it jammed (paper jam message).
Summary: I have used Dell for many, many years. This printer diappointed me. There was no manual in the box. It is only able to load about 10-12 sheets of paper in the tray. any more and it jams. I have tried three types of paper, same result for all. Now it is pushing 6-8 sheets through with every page I print. I have loaded, reloaded, etc. No success. Now hand feeding sheets through. If I had not discarded the box, I would send it back.
Summary: The printer prints cleanly and quickly but it's used for an office environment and we need to print checks. The paper feeds from the top of the tray and not the bottom, so consecutively numbered checks print out of order. I can flip the pages so they're fed in the right order, but I can't then convince the printer to print on the back (correct) side of the sheet.
