When your printer leaves black lines, the lines indicate that there are excess toner powders on the rollers or transfer belt within the printer. As the paper is moved along by the rollers and transfer belt, any excess powder left on them can result in lines being left on the paper.

The average lifespan of a printer is around 3-5 years. With proper upkeep and maintenance, some printers can last longer, but eventually your machine will need an upgrade.
The seventh alpha character of the serial number indicates the month of production and the eighth digit of the serial number indicates the year of production.
The streaks or lines might be caused due to low ink levels in one or both ink cartridges. Check the ink levels using the HP Toolbox to determine if the ink cartridges are low on ink and need to be replaced. note: Ink level warnings and indicators provide estimates for planning purposes only.
For most HP products the product label is on its bottom, its side, its top, or its back. On some products, it might be inside a battery compartment or behind an access panel. Your product label might look different depending on what HP product you own.

HP Laserjet 1320tn printing grey instead of black
ANSWER : Try this test. Put a page into the manual feeder and do that same test. When the end of the page is just about to enter the printer, open the lid. Take out the toner cartridge and pull back the shutter. Look at the image and see if it is black. The explanation is that there is high voltage going to both the toner cartridge and the charge transfer roller below it. If the image on the drum is black, then the fault is at the transfer roller not getting enough high voltage. The transfer roller pulls the image off of the drum and down onto the paper. It would not be a laser scanner problem as any issue with it would not result in an overall gray image, but combination of gray and black. It will probably turn out to be a bad HV power supply, which will need replacement. I’ve never seen this particular problem on this model.

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.

HP LaserJet 4200 paper jam fix
ANSWER : Yes, thank you! You did a thorough post! If your still hacking away at HP’printers you will know that unfortunately HP kept using that type of solenoid with the “Sticky Mess” on all of their new Equipment. I use this method almost everyday (without removing the actual solenoid). I’ve replaced so many I got carried away and now, I sell a solenoid repair kit! It’s for those people that like convenience. I provide a professional supply of perfect material with sticky back tape pre-cut to exact dimensions! All in a little kit. I have install videos, (I don’t charge for that I believe in the Do-it -Yourself approach.) Sorry for the sales pitch… but here is my link.
