From: Ian on 9 Apr 2008 10:18 I have a LaserJet 4000. Printed about 68000 pages. Always used genuine HP cartridges. Cleaned the printer each time a new cartridge was installed, per HP's instructions. Recently, printed pages have emerged with light smears of toner about 10mm (half an inch) wide down the left hand side. Within the smears I can see ghost images of previous pages that have already been printed. This does not look like a cartridge problem, more a drum problem perhaps? Ideas anyone? -- Ian

Try a new cartridge. ID
From: Arthur Entlich on 10 Apr 2008 09:17 Although HP toner cartridges are not cheap, the one advantage of them is that much of the printing engine is contained in them. As a result, often a printing defect can be corrected by "just" replacing the toner cartridge. This problem is most likely the wiper blade within the cartridge that cleans off the excess toner has deformed from use or heat, or age, or a positional defect, and is not fully contacting that edge of the drum to clear it of the last image created on it. If you have a second toner cartridge check to see if replacing it resolves the problem. It is also possible that the corona wires (if this laser has them accessible) may be contaminated with toner and it is probably worthwhile to give them a cleaning (if you can get to them, there is usually a small tool that comes with the printer or cartridge to clean them). Depending upon the age of the cartridge and if it is OEM or not, it may be warranted by HP, and they may replace it free of charge to you. Art Ian wrote: > I have a LaserJet 4000.

As it happens, the toner is already low, so I will see if I can raise a mortgage and get a replacement. (To think that these days you could buy two or three printers for the price of an HP cartridge. What is the world coming to!). -- Ian
