On the left side of the printer, press down on the latch at the top of the access door and pull the door open. Pull the duplexer out of the product.
Duplex printing means that your printer supports printing on both sides of the paper. Printers that are only capable of printing out documents single-sided are sometimes called simplex printers.
Duplex printing means that you can print on both sides of the paper with your printer either automatically or manually by turning the paper over after the first side has printed.
Manual duplex printing can achieve the same result as automatic duplex printing — the only difference is that you will have to turn the page over yourself to print the other side. On the other hand, in auto duplex printing, the printer does the flipping for you. This saves you time, money, effort, and paper!
Printing on both sides of paper is called duplex printing. Most printers offer the option of automatically printing on both sides of a sheet of paper (automatic duplex printing). Other printers provide instructions so that you can manually reinsert pages to print the second side (manual duplex printing).
HP® is proud to offer both inkjet printers and laser printers that are capable of double-sided printing.

Darker (not black) vertical band about 3/8" wide 3 1/2" from left edge only on odd sheets and only in duplex mode
ANSWER : If you are using letter sized paper, then this is a horizontal band since the paper feeds in landscape mode. Either way it is a really odd problem. There is no way it could be either the fuser or the toner as both of those would consistently do the problem, not intermittently. Also, does the band go all the way across the page or does it have borders on either end.
