How to Identify and Fix Common Problems ?

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.
If your laser printer is causing horizontal black lines you either have a problem with the optics or the drum. Cleaning the optics and replacing the drum should fix the problem in most cases.
Faint, streaky or spotty prints are all common signs of a clog but a simple cleaning can usually get your HP ink cartridges working again. Printheads clog due to infrequent cartridge use. If you regularly go a few weeks without printing, your cartridges will eventually dry out and need to be replaced.
Streaks and unwanted lines could mean that the printer heads are out of alignment. There`s an alignment tool in the printer`s control panel. If that`s not the issue then the printer is dirty. Printer ink stripes may appear along the edges of the paper, which means there`s ink on the rollers and other parts.
If you notice white or dark lines in your prints (also called banding), try these solutions before you reprint: Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary. Make sure the paper type setting matches the type of paper you loaded.
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.
Wipe clean the cartridge carriage where the cartridge connects to remove any dried ink (make sure the printer is off and unplugged). If the printhead is built into the printer, clean where the ink comes out with a damp cloth. Re-install cartridges and run a print head cleaning process.
The band-shaped “stripes” are called “horizontal bands” or “banding.” Horizontal bands are caused by the subtle changes in the movement distance that occur when feeding the media depending on the media`s thickness. We recommend making corrections to match the media you are using.
Although the printer might be correctly configured to print in Portrait mode, the program itself might be configured to print in Landscape mode. These settings are typically adjusted by locating a Page Setup or Page Layout menu and then looking for Orientation.

HP CM2320fxi MFP random color stripes
ANSWER : Had this problem with an HP Color LaserJet 3700dn unit not too long ago. In fact, it was not only doing the random multicolored stripes/bands across the page thing, it was also doing a repetitive palm print-like smudge of black toner on every page. I didn’t want to give up on this printer because on the few occasions in which it printed perfectly, the image quality was stunning and the colors were very impressive.
