How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

HP has determined that 99% of all lines and streaks on copies made by feeding the original documents through the ADF are caused by debris on the ADF glass. Debris can include dust, paper or toner dust, residue from sticky note adhesive, correction fluid or tape, ink, fingerprints, and more.
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.
A printer printing lines on the page are normally caused by a blocked, dirty, or damaged print head. Blocked ink cartridge nozzles, or not removing protective seals correctly when you installed a new ink cartridge can also cause missing lines of print.
Vertical lines in prints are an early warning sign of a low ink cartridge, which may show up before the printer`s low ink alerts start. You can fix the problem by replacing the low cartridge. Gently shaking the drained cartridge a bit may help to get another few prints out of it without vertical lines.
Delete lines or connectors

Click the line, connector, or shape that you want to delete, and then press Delete. Tip: If you want to delete multiple lines or connectors, select the first line, press and hold Ctrl while you select the other lines, and then press Delete.

Smears and smudges on the paper can be caused by dirt, dust, or toner accumulated on the rollers or transfer belt as it passes through the paper. Cleaning your printer, particularly the rollers, is one of the options for removing black markings from paper.
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.
There are four primary causes for horizontal banding on prints from inkjet printers, (1) nozzle clogs, (2) mis-aligned print heads, (3) low quality print settings (4) incorrect paper thickness settings. Below we will describe each of these causes for horizontal banding as well as ways to try and fix them.
The appearance of horizontal or vertical lines and wrinkles is due to various factors, among them genetics (loss of elasticity and firmness, slower cell renewal rate), hormone changes, sun exposure, smoking, pollution, stress and, of course, repeated facial expressions.
Streaks on your print jobs are a result of your copier glass being dirty. “Dirt” is created by fingerprints, dust, and other forms collected through usage. Often this will be detected by your device before streaks begin to appear, and a display will read that the glass needs to be cleaned.
A vertical line is always a line that runs from top to bottom, or, from bottom to top. Standing lines are also a type of vertical line that runs vertically. We usually draw vertical lines between the bases of a trapezoid or a parallelogram….
If your printouts are blurry or smeared, try these solutions: Make sure your paper is not damp, curled, old, or loaded incorrectly in your product. Use a support sheet with special paper, or load special paper one sheet at a time. Make sure your paper meets the specifications for your product.
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.

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.

Cant open HP Director in my mac
ANSWER : Try reinstalling it first from the CD and if that fails again, try downloading the software package from the official HP site and attempting an install that way. Apple makes it a pain to uninstall programs but doing an install on top of the existing one without first uninstalling could repair the issue. If you must uninstall the software there are programs that help uninstall programs from Mac systems.
