HP LaserJet 2100 Series Printer - Cleaning the Printer
To maintain print quality, follow the cleaning procedures listed below every time the print cartridge is changed, or whenever print quality problems occur. As much as possible, keep the HP LaserJet 2100 series printer free from dust and debris.
Using the printer cleaning processes
During the printing process, paper, toner and dust particles can accumulate inside the printer. Over time, this buildup can cause print quality problems such as toner specks or smearing. This printer has two cleaning modes that can correct and prevent these types of problems: engine cleaning and print cartridge cleaning.
This process uses copier-grade paper from Tray 2 to remove dust and toner from the paper path. Use this process if experiencing toner specks or dots on printouts. This process will provide a blank page, which should be discarded.
NOTE: In order for the engine cleaning page to work properly, print the page on copier-grade paper, not bond or rough paper.
Print cartridge cleaning
This process cleans the drum inside the print cartridge. Use this process if experiencing blurred, faded or smeared printouts. This process will take about 10 minutes. No page is produced by the print cartridge cleaning. The cleaning cycle is finished when the printer returns to a ready state, indicated by a steady green Ready light LED.
NOTE: Make sure the print cartridge is not empty when using the print cartridge cleaning process. A near-empty print cartridge may also cause print defects. This 10-minute process consumes toner, and if used, often can reduce print cartridge life.
Starting the cleaning process
Internal cleaning procedure
Over time, particles of toner and paper will begin to accumulate inside the printer. This may cause print quality problems during printing. Cleaning the printer will eliminate or reduce these problems.
WARNING: Before cleaning the printer, turn the printer off and unplug the power cable.
