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.
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.
The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
To resolve most print quality issues, use genuine HP cartridges, and in some cases, you might need to allow the printer to complete the automatic servicing routine. Check the paper and print settings to make sure that they are correct for the print job, and clean the cartridges and printhead.
During the printing process, paper, toner, and dust particles can accumulate inside the printer. Over time, this buildup can cause print quality issues such as toner specks, smears, or marks. The printer has a cleaning mode that can correct and prevent print quality problems.
If you start with a low-resolution image or other file, the resulting PDF may look blurry or pixelated, especially if printed out. PDF converters can`t make your finished document look any clearer than the original. Use files with resolutions of at least 72 dots per inch for Web display and 200 to 300 dpi for printing.
The drum cartridge may be defective. If you have a spare cartridge, replace and try to copy and print again. For details, refer to Replace the Drum Cartridge or follow the installation instructions that are included with the new cartridge. If the problem persists, contact Support.

“Normal” or “Standard” quality is the default print quality option. This is the best choice for most print jobs. “Best” or “High” quality produces the highest quality print and uses the most ink. Choose this for photos or presentation-grade prints.

HP Laserjet 4100 Error (13.1)
ANSWER : I am pretty late to the party for this discussion but I am incredibly thankful to the person that posted this “fix” that I can barely imagine it. My 4100 had developed the dreaded paper jam described above and I had no idea what was causing it. I replaced a number of rollers only to have the same problem re-occur with no solution in sight.

Laserjet 4250 print quality issue (see image)
ANSWER : It looks like a fuser problem. One way to prove it is with the half-stop test. Put a sheet in the drop down manual feed tray. Send a print job and watch the paper. When the end of it is about to enter the printer, open the lid and take out the toner cartridge. Look at the printed image. If it looks OK, then it is a fuser problem. If not, then it is a toner cartridge issue since it hasn’t gone through the fuser.

HP Laserjet 1320tn printing grey instead of black
ANSWER : Try this test. Put a page into the manual feeder and do that same test. When the end of the page is just about to enter the printer, open the lid. Take out the toner cartridge and pull back the shutter. Look at the image and see if it is black. The explanation is that there is high voltage going to both the toner cartridge and the charge transfer roller below it. If the image on the drum is black, then the fault is at the transfer roller not getting enough high voltage. The transfer roller pulls the image off of the drum and down onto the paper. It would not be a laser scanner problem as any issue with it would not result in an overall gray image, but combination of gray and black. It will probably turn out to be a bad HV power supply, which will need replacement. I’ve never seen this particular problem on this model.
