Cleaning the printer

General guidelines

Follow the cleaning procedure on the following page every time the print cartridge is changed or whenever print quality problems occur. As much as possible, keep the printer free from dust and debris.

  • Clean the outside of the printer with a slightly 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 (the black, rubber roller located underneath the print cartridge). Skin oils on the roller can cause print quality problems.

Cleaning procedure

  1. Turn the printer off and unplug the power cord.

    Figure 2: Turn off the printer

  2. Open the top cover and remove the print cartridge.

    WARNING: Avoid reaching too far into the printer. The adjacent fusing area might be hot!
    CAUTION: To prevent damage to the print cartridge, do not expose it to light for more than a few minutes.

  3. Wipe any dust or dirt off the paper feed guides (shaded areas) with a dry, lint-free cloth.

    NOTE: If toner gets on clothing, wipe it off with a dry cloth and wash clothing in cold water. (Hot water sets toner into fabric.)

Cleaning the fuser

Run the printer cleaning page to keep the fuser free of toner and paper particles that can sometimes accumulate. Accumulation of toner and particles can cause specks to appear on the front or back side of print jobs. For more information, see the Specks section in the User Guide.

To ensure optimum print quality, HP recommends that the cleaning page is used every time the print cartridge is replaced or on an automatic schedule.

A cleaning page can be run in two ways:

  • manually, as needed from the printer control panel

  • automatically, according to a set interval

The cleaning procedure takes about 2.5 minutes to complete. A message on the control appears while the cleaning is taking place (either PROCESSING CLEANING PAGE or PROCESSING AUTO CLEANING PAGE).

Running the cleaning page manually

In order for the cleaning page to work properly, print the page on copier grade paper (not bond, heavy, or rough paper).

To run the cleaning page manually:

  1. At the printer control panel, press Menu until PRINT QUALITY MENU appears.

  2. Press Item until CREATE CLEANING PAGE appears.

  3. Press Select to create the cleaning page. A page with a black stripe prints.

  4. Follow the instructions on the cleaning page to complete the cleaning process.

Running the cleaning page automatically

Using the procedure below, the printer can be set to run cleaning pages automatically at a set interval.

In order for the cleaning page to run without intervention, the selected size and plain paper type must be available in the printer.

The printer will not interrupt a printing job in process.

The output page created by the automatic cleaning process can be discarded.

To set the cleaning page to run automatically:

  1. At the printer control panel, press Menu until PRINT QUALITY MENU appears.

  2. Press Item until AUTO CLEANING PAGE=OFF appears.

  3. Press -Value+ to change OFF to ON and then press Select .

  4. Press Item until AUTO CLEANING FREQUENCY=2000 appears.

    NOTE: The default frequency is every 2,000 pages. To change this value, press -Value+ up or down. The options are 1,000, 2,000, 5,000, 10,000, and 20,000 pages.
  5. After the page frequency is set, press Select to save the choice.

  6. Press Item once again until CLEANING PAGE SIZE=LETTER appears.

    NOTE: The cleaning page can be run on either Letter size or A4 size.
  7. Press -Value+ to select either A4 or Letter and then press Select to save the selection.

Performing preventative maintenance

Certain printer parts should be replaced when the PERFORM PRINTER MAINTENANCE message appears on the printer control panel. This will help ensure that the printer maintains optimum performance.

The maintenance message will appear every 200,000 pages. To check the number of pages the printer has printed, print either a configuration page or a supplies status page. For more information, see the Configuration Page section or Supplies Status Page section in the User Guide for details.

To order the printer maintenance kit, see the Ordering Information section in the User Guide.

NOTE: To order Parts, Supplies, and Accessories contact the nearest authorized HP Dealer or Reseller. Click here to go to a list of Dealer locator phone numbers, or refer to the online User Guide.

The kit includes:

  • fuser

  • rollers (transfer, pickup, and feed)

  • instructions

    NOTE: The printer maintenance kit is a consumable item and is not covered under warranty.

Configuring alerts

HP Web Jetadmin or the printer’s embedded Web server can be used to configure the system to alert users of problems with the printer. The alerts take the form of e-mail messages to the e-mail account or accounts specified.

The following can be configured:

  • the device to be monitored (in this case, the printer)

  • what alerts are to be received (for example, alerts for paper jams, paper out, toner low, toner out, and cover open)

  • the e-mail account to which the alerts should be forwarded
