hp laser jet printer fading printout problem...?

I don't know which Laserjet you have, but the smoke isn't good, sounds like the low voltage power supply or the fuser could be bad. If the print is faded could be the toner cartridge or again the fuser, not fusing the toner to the paper properly. If I knew which Laserjet model you have I could pinpoint it more, but from my experience, not fusing properly and smoke is usually a low voltage power supply and/or fuser.

You have a bad fuser. The "smoke" that you are seeing is toner. It is not getting hot enough to stick to the page. You will have to call HP or a local computer store.

looks between PCL5 and six, they dropped the "handbook duplex" option, maybe for the justifications you reported. i might advise in basic terms printing pages manually, overlook "duplexing" suggestions. What you do is print astonishing pages first, pick pages to print like a million,3,5,7,9 Print those, turn the stack over, and print pages 10,8,6,4,2. Repeat for last 40 5 pages. each now and then, Adobe Reader has a print option reported as "Subset" (in basic terms under print variety), the place you are able to pick all astonishing pages or all even pages. It additionally supplies the choice to "opposite pages" for the opposite order for the returned pages - attempt it... Do an uncomplicated attempt with approximately 4 pages first, to make specific you get the flipping over superb.

Try taking a print using a different cartridge. If the problem repeats, you have to see a technician.
