My HP 3050 Laserjet printer is printing very lightly. It has a new print cartridge but that doesn't seem to help. Any suggestions?

May be bad toner cartridge or the laser is dirty (clean laser for better image)

If your HP Laserjet 1012's attention light is flashing,


Door open, media out, no print cartridge, or media jam

The printer is in an error state that requires operator intervention or help. Check the following:

• The print cartridge door is completely closed.
• Media is loaded.
• The print cartridge is correctly installed in the printer.
• There is no media jam.

1515n - I have the Magenta colour 'shadowing' the blue test. A mirror image of the blue text. [slightly staggered] Black is fine. Applies to all Word docs when printing in blue - can you help please?
I only use genuine cartridges.
Thanks

This document provides information about replacing the print cartridge for the HP LaserJet 1010 printer series, including life expectancy and replacement instructions. Print cartridge life expectancy The life of the print cartridge depends on the amount of toner that your print jobs require. When printing text on letter/A4-size paper at five percent coverage, the print cartridge lasts an average of 2,000 pages. This assumes that you set the print density to three and disable EconoMode. (These are the default settings.) See Ordering supplies for information on ordering replacement print cartridges. Changing the print cartridge Follow the below instructions to change the print cartridge:

1. Open the print cartridge door, and remove the old print cartridge. See the recycling information inside the print cartridge box. Figure 1: Removing old print cartridge CAUTION: To prevent damage, do not expose the print cartridge to light. Cover it with a piece of paper.
2. Remove the new print cartridge from the packaging, and gently shake it from side to side to distribute the toner evenly inside the cartridge. Figure 2: Gently shaking new print cartridge
3. Pull the tab until all the tape is removed from the print cartridge. Put the tab in the print cartridge box to return for recycling. Figure 3: Removing tape from print cartridge
4. Insert the print cartridge in the printer, making sure that the print cartridge is in position. Close the print cartridge door. Figure 4: Inserting new print cartridge

Hope this helps

1. open the Printer Properties (or Printing Preferences in Windows 2000 and Windows XP).
2. On the Paper/Quality tab or the Finishing tab deselect EconoMode check box.

I have same printer (Laserjet P2015D) with light print brand new and banding and shadows on solid areas. Tech support at HP has ruled out that the new cartridge needed breaking in (15-30 copies). They are now saying it could be a fuser issue and since the machine is brand new I should exchange it at the retail store. Disappointing because box stated it was mfg in Japan and I was expecting better.
