Running out of ink

If your printer runs out of ink, obviously the pages will come out blank when you attempt to print out what you need. Most of your HP printers will already have some kind of indicator to let you know that you are running slot. Solution: The solution is a no-brainer. Replace the ink cartridges.

There are numerous possible causes for a printer that`s randomly producing blanks. The most common ones are empty ink cartridges, improper cartridge installation, and congested nozzles. Driver and software issues can sometimes cause this problem as well.
This can be caused by debris or contamination on the drum, the transfer corotron, the device not positioned properly on a solid flat, level surface, or by using old or damp paper.
Open the start menu and select Control Panel > Administrative Tools > and choose the Services icon. Locate the Print Spooler service and right-click. Then select the option to “Stop” the service.
Make sure your printer is securely connected to your PC. The ink isn`t running out and the ink cartridges are not clogged. There`s enough paper in the paper tray. Restart your printer and give it a refersh, it could be just a glitch.

Your printer can become misaligned if there is any paper stuck in the machine, print cartridges are clogged or dirty, improper installation of cartridges and using low quality cartridges. Additionally, a printer can become misaligned after the machine completes a large print job.
For cleaning, HP recommends using HP Equipment Cleaning Wipes, but you can use an HP-approved lint-free wipe and deionized or distilled water. Note: If dark spots appear on back side of prints, clean drum screen. Note: If minilab prints more than 2000 prints each day, clean drum screen up to twice daily.
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.
Determine how long the cartridge has been installed. White streaking through the printout or an entire missing color both indicate an empty cartridge. If the cartridge is depleted of one color, it needs to be replaced. Each color is necessary to create the colors used in day-to-day printing.
The product prints a nozzle check pattern. Check the printed pattern to see if there are gaps in the lines. If there are no gaps, the print head is clean and you can continue printing. If there are gaps or the pattern is faint, clean the print head.
Trick the printer.

Low ink doesn`t mean no ink. Remove the cartridge, wipe it with a lint-free cloth and reinsert it. This process can fool your printer into “thinking” you`ve put in a new cartridge and may help it eke out a few more pages.

Choose “Printing Preferences” from the pop-up menu, then look at the setup options your print driver provides. Usually, there will be one called “Layout” or “Page Layout.” Once you`ve clicked “Layout,” you should have the option to manually set your margins to zero.
The correct answer is Margins.

HP Laserjet 6MP wont feed paper
ANSWER : I had a similar paper pickup problem on laserjet 6mp. The printer would go through start-up sequence fine but when it received a print job you could here the main gears/rollers turning but no clicking from paper pickup solenoid, then eventually error lights would come one . I incorrectly assumed it was an error with the paper pickup mechanism and wasted a whole day taking the printer apart and replacing the paper pick mechanism. Long story short, if I had bothered to figure out the secondary error light codes from the start, I would have realized it was just a bad fuser and would not have wasted so much time.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.
