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.
Printing on both sides of paper is called duplex printing.
These duplex printing is not working problems can be fixed by reinstalling applications, resetting settings and preferences. Sometimes some OS files, as well as drivers, can get out of date and trigger issues with performance or program procedures.
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.
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.
Click File > Print. In the Printer list, select the printer you want to use, then click Printer Properties. If you see options for “duplex printing,” “print on both sides,” or something similar, your printer supports duplex printing.
Duplex printing is a feature of some computer printers and multi-function printers (MFPs) that allows the printing of a sheet of paper on both sides automatically. Print devices without this capability can only print on a single side of paper, sometimes called single-sided printing or simplex printing.
Two document pages are reduced and printed side by side on each side of each sheet, and then the whole stack is folded in half, like a magazine. For example, an A4 document will be printed as two A5 images on each side of A4 sheets.
Enabling double-sided printing in Windows

Open Start> Settings> Devices, and select the Printers and Scanners tab in the left menu. Click on the printer you would like to print double-sided from and select Manage. Select Printer Properties from the left menu.

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.
Paper feed issues might result from dusty, torn, wrinkled, wet, or folded paper in the tray. The quality of the paper can also make a difference. Follow these guidelines to help avoid the issue. Use only good quality paper that meets product specifications.

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.
