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.
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.
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.
To resolve this situation, get a lint-free cloth, a soft paint brush and some isopropyl alcohol to clean any rollers within reach. Always make sure you are wearing gloves before carrying out any cleaning as you do not want to get ink on your hands or leave marks on the rollers.
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.
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….
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.
Streaking is usually caused by a worn out drum unit or spent toner cartridge. Drum units are a consumable and only need to be replaced after the use of 3 or 4 toners. Not all printers use a separate toner and drum unit.
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.
The equation of a vertical line is of the form x=c, where c is any real number. The vertical line will always intersect the x−axis at the point (c,0). The slope of a vertical line is undefined.
The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). because division by zero is an undefined operation.
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.
What causes vertical lines on a TV screen? Vertical lines on a TV appear for the same reasons as horizontal lines: loose cables and wires, screen damage, or a faulty T-Con board. Leaving the TV turned on for too long can also cause vertical lines.

Scan lines are important in representations of image data, because many image file formats have special rules for data at the end of a scan line. For example, there may be a rule that each scan line starts on a particular boundary (such as a byte or word; see for example BMP file format).
The sponge end of a blocked printer head can be cleaned with only one liquid other than water. This liquid is isopropyl alcohol. Isopropyl alcohol isn`t strong enough to melt the sponge but is still strong enough to dissolve the ink inside the blocked printer head.
You`ll know fairly quickly if your printhead is causing you problems. If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead.
Use isopropyl alcohol or ethanol according to the manufacturer`s safety guidelines, as applicable. Wipe the roller with a lint-free cloth dipped in isopropyl alcohol or ethanol. After cleaning the roller, make sure that no lint or other material remains on the roller.
For cleaning, HP recommends using HP Equipment Cleaning Wipes, but you can use an HP-approved lint-free wipe and deionized or distilled water. Note: If dark spots appear on back side of prints, clean drum screen. Note: If minilab prints more than 2000 prints each day, clean drum screen up to twice daily.
Ghost prints happen when the drum or fuser unit within your printer become faulty. Because a fault with this element won`t heat the particles of the toner to a high enough temperature, the marks being made on the paper are much lighter in colour and appear more faded than typical documents.
Dirty printheads

Dirty nozzles, leftover toner, debris, or dust can interfere with your printer and cause ghosting. Run the printer`s built-in cleaning function multiple times, and print a test page between each. Repeat this process until the ghosting issue disappears.

Soak the Printhead

Fill a bowl with warm water (or a mixture of water and vinegar to clean the printhead) and place the printhead directly in it. Let it sit for five minutes or so. Pull the printhead out of the water and use a lint-free cloth or paper towel to remove the dried ink.

Surface cleaning refers to the removal of dirt, dust, varnish and other debris from the surface of an object. By cleaning, colors may become more vibrant, details may become more clearer and previously unseen aspects of an object may become more visible. St.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.
