How to Identify and Fix Common Problems ?

HP EasyColor scans documents and automatically adjusts photographic images in . JPEG or . PNG format. Rather than dividing an image into several pieces, HP EasyColor technology enhances the entire image at one time, which results in improved color consistency, sharper details, and faster printing.
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.
From the Home screen on the printer control panel, swipe left, and then touch Setup. Touch Service, and then touch Cleaning Page. Load plain, white paper when you are prompted. Touch OK to begin the cleaning process.
Here are the most common causes of a printer printing faded text or images: Low ink or toner levels. Toner sticking to the fuser roller or problems with the transfer roller. Low ink or toner density settings.
If the ink cartridge in your printer is out of cyan or the head is clogged preventing it from reaching the nozzles in the printer, then only the yellow and magenta inks will be printed on the paper. This will give the picture a reddish/orange/yellow tint.
Black and white, Monochrome, Black Ink Only, or Grayscale: Uses only the black cartridge to print in black and white. High Quality Grayscale: Uses all colors and black to print higher quality black and white prints.
Paper Jams

This is a common laser printer problem. Primary causes include grime, dust, worn rollers, or incorrect paper weight. The most basic way to prevent paper jams is simply through regular cleaning of your printer. Also, replace parts as needed.

If the paper is too thick, glossy or not designed for laser printing, ghosting will most likely occur. Dust and debris inside the printer can also cause ghosting as too much dirt can interfere with the drum units, transfer units and fuser units.
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.
Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary. 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.
The way colours are displayed on a computer monitor is by emitting light through combinations of red, green and blue LEDs (RGB). However, in digital print (eg. a desktop printer or commercial digital press) we generally see colours through light passing through dots of cyan, magenta, yellow and black ink (CMYK).
Remember, printers use both black and colour inks when printing grayscale, so you`re not saving anything by doing so unnecessarily. Some printers will print with only a black ink cartridge installed – if your printer does this, you can technically save ink and use black ink only to print.
Grayscale is generally not recommended for printed pieces used for promotional purposes, such as brochures, postcards, or presentation folders. Full-color printing is the better choice when trying to promote a company, product, or service.
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. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
For example, if you mainly print black and white text, then using the monochrome setting or investing in a monochrome printer is the best choice. Grayscale printing is better for black-and-white images, because of this setting`s ability to create various contrasting shades and finer details.
As print quality goes down over time, this will be a reason to replace the color printer. We find a black and white printer can sometimes last 10 years or more and most color laser printers are replaced every 3 to 5 years.
Print blemishes after inserting a new cartridge. Slow print times. Abnormal noises. Paper jams and ripped paper.
Check the toner darkness settings.

Sometimes light print can be remedied by simply changing the toner darkness setting in the printer. To change the setting, go to MENU>>SETTINGS>>QUALITY MENU>>TONER DARKNESS. Increase the darkness and send a test print to see if that fixes the issue.

While you still should keep your distance from that coughing coworker, you also should avoid sitting near the printer, as its toner could be toxic to your health.
Toner cartridge issue: The most common cause of black shadow printing is a faulty or damaged toner cartridge. If the cartridge is not seated properly, or if it`s damaged or old, it may produce uneven or incomplete prints. Drum unit issue: The drum unit is responsible for transferring the toner to the paper.
If your printer is spitting out pages full of strange characters, symbols, or strange formatting, your inkjet printer drivers may be outdated, incompatible with your operating system or corrupt. Drivers are important to the proper function of your inkjet printer and it is best to check for updates regularly.
Automatic print head cleaning

The cleaning function is included in the software of almost every printer. Usually, you can find it under the “printer maintenance” section of your printer`s display menu. Automatic print head cleaning usually takes only one or two minutes, so you won`t need to wait for too long.

Deep Cleaning consumes a larger amount of ink than Cleaning. Cleaning the print head frequently will rapidly deplete your printer`s ink supply. Consequently, perform cleaning only when necessary.
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.
