How to Identify and Fix Common Problems ?

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.
Dirty or misaligned print heads

Your printer may be printing fuzzy, blurry, or other faint text because of dirty print heads. All modern printers have a self-cleaning mode, which cleans the print heads, and additional internal equipment used in the printing process.

The print nozzles, print head, and other internal components could be clogged or dirty, causing blurry text. In other words, you should clean the interior of the printer.
A common cause of faded, faint printouts from your inkjet printer is dried ink particles causing a blockage in your printer. The printheads on an ink cartridge can be become blocked if the printer is not used for a period of time, so it is recommended to print a few pages each month to maintain the print quality.
Another thing you can do to your image to improve its clarity when printed is to apply some Sharpening to the image. Prints need more sharpening than computer monitors, so apply just a little too much. When you apply Sharpen you have to zoom the photo to 100%.
The standard resolution in most laser printers today is 600 dots per inch (dpi). This resolution is sufficient for normal everyday printing, including small desktop publishing jobs. A high-end production printer might have a resolution of 2400 dpi. Some laser printers still use a resolution of 300 dpi.
Large photos with a very high resolution will become compressed when printed, causing some blurriness because printing resolution is much more limited than camera resolution. This is generally only a problem when printing on a small sized print or product but is not a problem for large products.
Printers may produce poor quality printing if they are exposed to too much heat. Don`t place your printers in a high-temperature area or near other devices that produce excess heat. In addition, keep them away from windows, where heat and humidity can be high.
Press your printer`s Setup button. Go to System Setup. Choose Print Quality and then Calibrate Color. Choose Calibrate Now and press OK.
The reason that onscreen colors look different offscreen is because some colors onscreen cannot be reproduced with CMYK printing. These colors are called “out of gamut.” Example colors are metallics and fluorescents. The RGB color space has a much wider range of discernible colors than CMYK.
The first step in printer calibration is to calibrate your monitor. Then, make sure you use the correct printer driver for your printer. Within the printer driver are controls for fine-tuning the overall appearance of color from your printer. Depending on your needs, this may be sufficient to get the color you want.

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.
