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.
Avoid exposing the imaging cartridge to light, and never open the drum`s protective cover as this may damage the light sensitive drum. Overexposure of the drum may cause very dark or light areas to appear on printed documents and reduce its functional life.
Common causes include dust and grime, worn rollers, or inappropriately weighted paper. Prevent paper jams by regularly cleaning your printer and replacing parts as needed. Check the weight of paper that your printer is rated for as well. The printed product is faded.
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.
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.
1. Paper Jams. Paper jams are a common problem for printers, resulting in time-consuming and frustrating delays. It can occur when loose sheets of paper get stuck in the rollers or feeding mechanism of the printer.
Ink and toner problems can include streaking and fading (which usually indicates a dirty print head) or toner in a laser printer that is running low. For inkjet printers, the print head may need a good cleaning. The printer utility app that came with your printer will include a cleaning option.
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.
If you keep the printer turn on for long periods of time, it will not have much of an effect on the printer`s components. It does not cause the printer to malfunction. If you want to reduce your electricity consumption, you can avoid keeping your laser printer on all the time.
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.
What maintenance does a laser printer need? To keep your printer running at maximum capacity, you need to maintain its working parts. Dust and wipe it down regularly inside and out with a no-lint towel and rubbing alcohol. Turn off your printers regularly, especially when they aren`t in use for a long while.
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.
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.
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.

Print file sent but no printing occurs
ANSWER : Been working on these since they first were released. Never seen a problem like yours. If it happens again, try doing an engine test, as it bypasses the formatter board. The engine test is located at the right side of the manual tray opening. Look for a hole in the side wall. Stick something like a paper clip into it to actuate the test button. It will then print a lined test page. If it does that, then it points to the formatter board as the cause of your problem.

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.
