If you want to clean the pickup roller before deciding to replace it, follow these instructions:
HP LaserJet Pro P1102, P1102w, P1106, and P1108 Printers - Cleaning the Product
Clean the paper path
If you are experiencing toner specks or dots on the printouts, clean the paper path. This process uses a transparency to remove dust and toner from the paper path. Do not use bond or rough paper.
Figure : Printout with specks or dots
note:For best results, use a sheet of transparency. If you do not have any transparencies, you can use copier-grade media (60 to 163 g/m2) that has a smooth surface.
Make sure that the product is idle and the ready light is on.
Load paper in the input tray.
Open the printer Properties.
Click the Device Settings tab.
In the Cleaning Page area, click the Start button to process the cleaning page.
note:The cleaning process takes about 2 minutes. The cleaning page stops periodically during the cleaning process. Do not turn the product off until the cleaning process has finished. You might need to repeat the cleaning process several times to thoroughly clean the product.
