How to Identify and Fix Common Problems ?

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

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.
Press your printer`s Setup button. Go to System Setup. Choose Print Quality and then Calibrate Color. Choose Calibrate Now and press OK.
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.
Dots are typically caused by foreign material inside the machine (for example, paper dust, glue from labels or envelopes, paper clips, staples) sticking to or damaging the surface of the drum. Toner builds up on or sticks to these areas on the drum and creates black dots on the printed pages.
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.
Gently press on the print`s corners, or whichever side you are trying to straighten up, and they should easily bend until the bottom is completely flat. Keep your fingers in position for 3-5 minutes until the print and the pan have cooled off a bit.
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.
The ink cartridges may be old or low on ink, and you may need to replace them. Your printed colors can never exactly match your on-screen colors. However, you can use a color management system to get as close as possible. Try using the color management options in your printer software.
Paper curl is caused by an excess amount of moisture in the paper. The first step to ensure less paper curl is to store your paper in a cool, dry area. By doing so, you will reduce the amount of moisture and humidity the paper is exposed to. The next step is to always fan the paper before placing in the machine.
Faulty and loose connections are the most common cause of horizontal lines on a TV. If you recently moved your TV, you might not have properly connected the cables. This is especially true if you`re using HDMI cables. Loose cables can easily slip out of their ports.
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.
Dots are typically caused by foreign material inside the machine (for example paper dust, glue from labels or envelopes, paper clips, staples) sticking to or damaging the surface of the drum. Toner builds up on or sticks to these areas on the drum and creates black dots on the printed pages.
This occurs due to the binding position automatically being set to [Long Edge [Top]] when the printing orientation is [Landscape].
Warping occurs due to material shrinkage while 3D printing, which causes the corners of the print to lift and detach from the build plate. When plastics are printed, they firstly expand slightly but contract as they cool down. If material contracts too much, this causes the print to bend up from the build plate.
3D print warping happens when extruded filament layers on the 3D printer build plate cool too quickly and shrink. This causes the plastic material to contract and pull away from the build plate, resulting in warping (or curling, as it is sometimes known).
Banding happens when you do not have enough information in your file. Or you push the edits to an extreme. Avoid banding by making a well-exposed photograph and saving it as an uncompressed RAW file. To fix color banding, make subtle edits and limit how much you compress the photo when exporting as a JPEG.
Banding can be created when there isn`t enough tonal range to represent all the different colors between the brightest and the darkest points of a gradient. The tonal range is given by the number of bits. An 8-bit photograph will have 256 tonal values per color and a 16-bit one has 65,536.
Horizontal Lines go side to side. They can be straight or could zig-zag or curve. If you think about the horizon line (where the sky and ground meet) it will help you remember the word horizontal.
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.
White lines will typically start appearing on your print outs due to a clogged up printer head. Your first port of call when solving this problem is to run the cleaning program on your printer, which should be accessible through its settings menu.
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.

My 2550n Color LaserJet does not want to print in color
ANSWER : That model had issues with the carousel solenoid sticking. That might explain why it works after you let it sit for 10 minutes. The solenoid gets hotter with use which causes the deteriorated foam on it to become sticky and hold down the release plate instead of letting it go. This allows the carousel to spin when it is supposed to stop for each color. The solenoid is located on the right side of the printer. If you open the lid, it is just behind the opening at the top right. You need to remove the top of the printer and scrape off the goo on top of the solenoid body. I put a piece of thin sticky backed felt to replace it. Other people use electrical tape.
