If the display panel on your HP LaserJet reads “Perform Printer Maintenance”, “Perform User Maintenance”, “Maintenance Kit Low”, “Maintenance Kit Very Low”, or anything along those lines it means your printer needs a preventative maintenance kit, which includes a fuser and various rollers.
Adjust the application settings and the printer settings to the highest possible resolution. Both of these features can typically be accessed from the “Print” menu. Dpi settings can range between 72 dpi and 2400 dpi. Choose the highest dpi setting available for best results when using a laser printer.
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.
A maintenance kit is a set of replacement parts for a printer. Each printer has a preset maintenance interval, which occurs after a certain amount of pages are printed. The maintenance interval lets the user know that it`s time to install the maintenance kit so that the parts within the printer do not get overused.
If you notice that your print quality is uneven, too light, too dark, or there are vertical or horizontal lines in the print (banding), try these solutions: Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary. Align the print head.
The Original HP Maintenance Cartridge is designed to make your HP Designjet printer even easier to use by enhancing system reliability. You get trouble-free printing—every time—and fewer interruptions to help you get the job done right and on time.
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.
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.
In general, you should update your printer maintenance kit every one to two years. However, once every year or once every other year is the bare minimum. Even if your devices are running fine and you don`t think it`s necessary, it`s wise to perform regular checkups.

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.
