HP LaserJet 2100 Series Printer - Cleaning the Printer

Overview

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.

  • Clean the outside of the printer with a lightly water-dampened cloth.

  • Clean the inside with a dry, lint-free cloth.

    CAUTION: Do not use ammonia-based cleaners on or around the printer. While cleaning the printer, be careful not to touch the transfer roller (located underneath the print cartridge). Skin oils on the roller can cause print quality problems.

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.

Engine 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

  1. Make sure the printer is turned on and in the ready state. Make sure there is paper loaded in Tray 2.

  2. Press and hold the GO and JOB CANCEL buttons until all lights flash. This will take about 10 seconds. Release the buttons when the lights flash.

    NOTE: After pressing and holding the buttons, the lights will go from flashing in unison to flashing in sequence during the cleaning cycle.

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.
  1. Open the top cover.
  2. Remove the print cartridge.
    CAUTION: To prevent damage, do not expose the print cartridge to light for more than a few minutes. Place a piece of paper over the top of the print cartridge to shield it while it is out of the printer.
  3. With a dry, lint-free cloth, wipe any residue from the paper path area and the print cartridge cavity.
  4. Replace the print cartridge and close the top cover. Plug in the power cable, and turn the printer on.
