How to Identify and Fix Common printer Problems ?

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

Clean the print head, if necessary. Make sure the paper size, orientation, and layout settings in your printer software are correct. Make sure your document does not contain blank pages. If your printer software has a Preview option, you can check for blank pages before you print and remove them, if necessary.
Check Cables and Printer USB Ports

Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.

When the print driver is corrupted, the target printer interprets the data stream as random characters. This problem can usually be solved by re-installing the print driver or checking the printer setup in the Control Panel.
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.
In some respects, the signs that your printer has been infected with malware are similar to the general signs of a malware infection on your computer, the signs include unusual behaviour by your printer, such as not responding to your commands, printing unauthorised print jobs and refusing to install security updates.
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.
If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.
When printing on paper that is even slightly moist from humidity, ink can become smudged on the paper, colors can run together, and text or images can be distorted. Check if the paper is moist and try replacing the paper in the printer to see if print quality improves.
What is about:blank? The about:blank page, also called About Blank, is an empty page on your browser tab that appears when your browser has nothing else to show. The about:blank page can display because you don`t have a home setting for your browser or because the web address you entered doesn`t exist.
The print head cleaning function allows you to clear up clogged print head nozzle. Perform print head cleaning if printing is faint or a specific color fails to print, even though there is enough ink.
Usually a quick paper setting adjustment will clear up a ghosting issue right away. Run a cleaning – Most printers have a cleaning function built into the machine. Run this a couple of times to attempt to clear up the printing issue. Inspect the drum – Sometimes excess toner powder can stick to the drum.
Shadow printing is a printing technique that creates a lighter shade of the text off centered to make the text appear to have a shadow beneath it.
In the majority of cases, printers` self-cleaning mechanisms clean blocked printer heads by flushing the nozzles with air. The air works to dislodge dry ink inside the cartridge channels and also push it out. The intensity of the self-cleaning process of printers is usually not very strong.
During the printing process, paper, toner and dust particles can accumulate inside the printer. Over time, this buildup can cause print-quality problems such as toner specks or smearing. This printer has a cleaning mode that can correct and prevent these types of problems.
Just like computers, printers have volatile memory (RAM) that is removed when you turn the printer off. Volatile memory requires power to store the information. Deleting volatile memory is easy: Simply shut down or unplug your printer for a minute or so.
Un-authorized printing jobs− If your machine is printing unknown documents that nobody authorized, your printer may be compromised. Error messages− If your printer is displaying error messages or printing documents with error messages instead of the actual document, your printer may be corrupted.
Can you print with one or two empty ink cartridges? The quick answer is: Yes, you can (if you own a printer model that allows it) — but you shouldn`t keep printing with an empty cartridge for too long.
Ink cartridges can dry out over time. If they are sitting in your machine for an extended period, they will eventually dry up and become unusable. The simplest way to combat this problem is by printing more frequently or running regular cleans and ink tests to ensure the nozzles remain clean.
The shelf life for an original printer cartridge is 24 months and the shelf life for a compatible cartridge is 36 months. Over time, ink dries out and settles inside the cartridge, which can cause your printer to clog.
Reset. Resetting the printer stops printing and clears the current print job received from the active interface. You may want to reset the printer when there is a problem with the print job itself and the printer cannot print successfully.
In the Command Prompt type, net stop spooler, then press Enter to Stop the Print Spooler. In the Command Prompt type, net start spooler, then press Enter to Start the Print Spooler.
Press the Windows key+r or select Start and type run and select it. 2. Type printmanagement. msc and press enter or select the OK button.
A mistake in anything that`s printed is a misprint. You might also call it a typographical error or typo. Misprints are an embarrassment for the publisher, since they`re evidence of a hasty printing job or a lack of careful proofreading.
This is usually a problem with drivers. The only way to solve the problem is to install new drivers or update the one you have been using. Usually, weird characters appearing on your printing papers means there is no communication between your printer and the computer it is connected to.

Prints blank pages, won't print from computer
ANSWER : Don’t know why you replaced the fuser, but assuming you had print before, then it must have been something you did during the procedure. Only thing I can suggest is to recheck your work. Just because you reinstalled a connector doesn’t mean that it is seated firmly enough to work. Any flat ribbon connectors that you removed and reinstalled, check to see that the contacts are all flat and not peeled back.
