Question about HP LaserJet 2100 Printer
Usually the ghosting of image is due to bad fuser. since the fuser is not hot enough to fused the ink to the paper, the image is then transfer to the roller from the paper, you have ghost.
try to clean the rollers, inside of the machine and the paper pickup roller.
if you suspect the roller is not clean, you can change it. get a maintenance kit form HP. or other reseller.

Okay, this is going to be difficult to isolate.
From the service manual: "Repetitive print defects usually are associated with a specific roller within the printer or the Toner Cartridge. Use Figure 7-1 to isolate the cause of repetitive print defects. Align the first occurrence of the defect with the top of the “ruler” (at the top or bottom of the misprinted
page), and measure to the next occurrence of the defect to determine the roller in question.
When the defect pattern matches the pattern of the ruler, replace the indicated roller."
I can't post the ruler from the service manual here, but it gives some measurements.
Start with the initial point where the occurence started then measure down to the next occurence.
If it occurs at 38 mm, then it is your primary charging roller.
At 42 mm, feed roller.
44mm, registration roller
46mm, transfer charging roller
50mm, developing cylinder
63 mm, pressure roller
75mm fusing film unit
94 mm, photosensitive drum
I hope this helps :c)
