Diamond Bar, Ca HP LaserJet Printer Cleaning

By cleaning your HP laser printers, you’re sure to lengthen your printer’s life and avoid the troubles of printer malfunction caused by not performing the task mentioned. Most printer users tend to search the internet on how-to’s but end up finding complicated steps that’s why in this article, we’re going to show you three ways on how to clean that HP laser printer as easy as a piece of cake.

  • Cleaning the HP Laser Printer’s surface – When your HP laser printer’s surface gets dusty, you can just wipe it off the top using anti-static wipes or a paper towel, or use a can of compressed air and spray the top, removing the dusts.
  • Cleaning the Inside of Your HP Laser Printer – On the inside, the same compartment where you place your HP toner cartridges in, simply remove the cartridge then use compressed air to blow any dust particles stuck in the toner tray. If you see any large particles of paper that came from paper jams, pull out the remaining parts of papers before putting the toner cartridge back to its place.
  • Cleaning the Slot of the Paper Tray – That part can accumulate dusts too, so its better to clean it up as well by  first taking out the paper tray then the same as the printer’s surface, you use anti-static wipes, paper towel or compressed air to get the dusts off the printer.


Troubleshooting Your HP LaserJet Printer

Troubleshooting your Laser Printer

Laser printers contain many moving, mechanical parts and require regular maintenance to ensure reliable performance.

This troubleshooting information is intended only as a guide in determining the most common faults with laser printers and should not be used as an alternative to service provided by experienced technicians.

Light or Faint Print:

May be caused by the toner cartridge running low. Try a new toner cartridge , or to get a little more life from the toner cartridge, remove it carefully from the printer and give it a gentle shake from side-to-side. Also ensure that ‘economy mode’ is not selected. If a replacement toner cartridge does not fix the problem, a printer service is required.

No Power:

Ensure all electrical cables are securely connected and that printer covers and doors are closed properly. Power supply units and electronic boards can also fail on laser printers, and can be replaced by a technician.

Cannot Print:

Power down the printer and wait for 30 seconds before powering up the printer. This will clear the buffer or memory in the printer. Purge any documents in the print queue waiting to print via your computer. Resend the print job to determine whether the problem is resolved.

Marks on the Page:

Vertical or horizontal marks on the page are generally caused by the toner cartridge. Try a different toner cartridge (new or empty) to determine whether the marks are repeated. If a replacement toner cartridge does not fix the problem, a printer service is required.

All Black Pages:

Pages printing out completely black indicate a printer service is required. They are usually caused by a fault with the laser scanner assembly which will need replacement or cleaning by a technician.

All Blank Pages:

Can be caused by incorrectly fitted toner cartridge. Ensure that the plastic rip-strip is removed from the toner cartridge.

Paper Jam errors:

Remove toner cartridge and paper trays from printer to expose paper jam. Remove paper from the printer by gently pulling the paper in the direction of the paper flow. Remove any torn paper or foreign objects from around the area of the jam. Phantom paper jams; continuous paper jamming or multiple page feeding indicates a printer service is required.

Fixing or Fusing error (Error 50):

Fusers and/or fixing assemblies are moving parts inside laser printers and periodically require maintenance or replacement. Turn off the printer and let it stand idle for about 30 minutes. Power up again to determine whether the error message has cleared. If the service 50 error is still present, a printer service is required.


Solving Printer Problems

  • Clearing paper jams
  • Improving print quality
  • Understanding printer messages
  • Troubleshooting check list

Clearing Paper Jams

If a 13 PAPER JAM or 13 DUPLEX JAM message appears in the display panel, look for jammed paper in any of the locations. If you get repeated paper jams or if the paper jam message appears repeatedly, see ” Repeated Paper Jams” at the end of this section. Paper jams occur most often when:

  • Paper cassettes are not correctly loaded
  • Your print media does not meet the specifications
  • The media is in poor condition.
  • The printer needs cleaning.
  • User-replaceable parts are wearing out

The top cover or rear cover of the printer must be opened and then closed in order to clear the paper jam message. If paper jams occur frequently, clean the printer and check the quality of your paper or other print media.

Paper Jams: Paper Pickup and Transfer Guide Areas

  1. Remove the paper cassette
  2. Pull the paper out through the front of the printer

Do not force the paper. If you can see paper in the cassette opening but cannot remove it easily, remove the paper through the Transfer Guide Area (see next steps)

  1. Open the top cover and remove the toner cartridge.
  2. Raise the green handle to free the paper, and pull the paper out through the front of the printer.

Paper Jams: Fusing Assembly Area – Top Cover

  1. Open the top cover and remove the toner cartridge.
  2. Remove the paper by pulling it back out of the fuser, into the printer body. Roll the paper toward you to avoid spilling loose (unfused) toner.
  3. Clean any loose toner that may have fallen into the printer with a clean lint-free cloth

If loose toner falls into the fuser, it may cause print quality problems

If toner gets on your clothes, wipe it off with a dry cloth and wash your clothes in cold water. Hot water sets toner into fabric.

Paper Jams: Rear Cover – Fusing Assembly and Paper Exit Areas

The fusing area gets HOT.

  1. Open the rear cover.
  2. Open the rear door of the fusing assembly, if necessary
  3. Pull the jammed paper from the fusing assembly.
  4. Remove the leading edge from the paper exit in the output bin if necessary

Make sure that the orange packing spacers have been removed from the fusing assembly.

Paper Jams: 500-sheet Lower Cassette

  1. Partially remove the 500-sheet Lower Cassette
  2. Remove jammed paper.
  3. If necessary, partially remove the 500-sheet Paper Cassette and remove jammed paper.
  4. Remove any pages in the cassette that are damaged. Do not reload damaged paper into the cassette.

If there are frequent paper jams or multi-feed problems in the lower cassette area, see “Printing from the OPtional lOwer Cassette” and ” Repeated Paper Jams” at the end of this section.

Paper Jams: Optional Duplex Unit

  1. Remove the Paper Cassette
  2. Open the front access cover of the duplex unit and remove any paper. Also, remove any paper protruding from the rear of the duplix unit.
  3. Open the rear duplex door.
  4. Lift paper guide and remove any paper, then lift paper guide and remove any paper, then close.
  5. Close rear duplex door (it should latch when completely closed). Replace the Paper Cassette and close the duplex unit’s front access cover.

Repeated Paper Jams: Situations and Solutions

Repeated Paper Jams: Situations and Solutions

General repeated paper jam problems.
  1. Check to see that media is correctly loaded in trays (see Chapter 3, “Printing Tasks “).
  2. Previously printed paper or torn, worn, or irregular paper should not be used.
  3. Certain media jams, other media does not. For the recommended paper and other media for your printer, see Appendix C, “Media Specifications.” Try turning over the stack of paper in the tray.
  4. Parts may be worn. See ” User-Replaceable Parts ” in Chapter 7.
  5. If jams continue, contact your authorized HP service provider.
Multipurpose (MP) Tray repeated jams.If jams persist after you have cleaned the printer, check the media specifications and verify that you are loading the Multipurpose (MP) tray correctly (see Chapter 3 “Printing Tasks”). You may need to replace the Multipurpose (MP) Tray Pickup Roller as described in Chapter 7.
Paper Cassette repeated jams.If jams persist after you have cleaned the printer, check the media specifications and verify that you are loading the Multipurpose (MP) tray correctly (see Chapter 3 ” Printing Tasks”). You may need to replace the Multipurpose (MP) Tray Pickup Roller as described in Chapter 7. If using the universal (adjustable) Paper Cassette, verify that the paper size knob and other adjustments are set correctly and that the tray is not overloaded.
Lower Cassette repeated jams (not applicable at ING). Adjust the Lower Cassette as described in “Printing from the Optional Lower Cassette ” in Chapter3. Verify that the paper size, tension, and other adjustments are set correctly and that the tray is not overloaded. If two or more pieces of media are being selected at once, it may help to decrease the tension (turn the adjustment clockwise). If the media is not being picked up from the tray, increase the tension (turn the adjustment counterclockwise).

Improving Print Quality

General causes of print quality problems are given in the checklist below, followed by specific samples of common print quality problems. If the listed solutions do not work, call for help.

Print Quality Checklist

  • Redistribute the toner in the toner cartridge (see ” The toner Cartridge” in Chapter 7).
  • Clean the inside of the printer (see ” Cleaning the printer” in Chapter 7).
  • Adjust the print density (see “Adjusting Print ” )
  • Check the paper type and quality (see Appendix C, ” Media Specifications”).
  • Replace the toner cartridge, then check the print quality again.

Vertical Fade

If a vertical white streak or faded area appears on the page:

  • The toner cartridge toner supply is low. Remove the toner cartridge from the printer and rotate it back and forth. If shaking the cartridge does not improve the print quality, replace the toner cartridge.
  • The print density is too light. Adjust the density adjustment setting from the control panel (1 is light; 5 is dark). (see ” Adjusting Print Density” in Chapter 5).


If faded-out areas, generally rounded, occur randomly on the page:

  • The moisture content of the paper is uneven, or the paper has moist spots on its surface. Try paper from a different source.
  • The paper lot is bad. The manufacturing process can cause some areas to reject toner. Try paper from a different source.
  • The transfer roller is dirty. Replace the transfer roller (see ‘User-Replaceable Parts’ in Chapter 7).

Vertical Lines

If sharp black vertical streaks appear on the page, the photosensitive drum inside the toner cartridge has probably been scratched. Replace the toner cartridge.

If smeared black vertical streaks appear, the fuser may be bad. Inspect the rollers for scratches and excessive wear, and, if necessary, replace the fusing assembly as described in ‘User-Replaceable Parts’ in Chapter 7.

Toner Smear

If toner smears appear on the leading edge of the paper, the paper guides are dirty. Clean the printer as described in ‘Cleaning the Printer’ in Chapter 7.

If toner on the paper is loose or can be wiped off easily, your fuser may be damaged. See your service representative.

Background Gray Toner Shading

If the amount of background toner shading becomes unacceptable, the procedures described below may help to clear the condition:

  • Increase the density setting. This will decrease the amount of background shading.
  • Change the paper to a lighter basis weight.
  • Check the printer’s environment; very dry (low humidity) conditions can increase the amount of background shading.
  • Replace the toner cartridge
  • Replace the transfer roller.

Vertical Repetitive Defects

If marks appear repeatedly on the printed side of the page:

  • The toner cartridge is damaged. The circumference of the toner cartridge drum is 3 3/4 inches (95 mm). If a repetitive mark occurs every 3 3/4 inches on the page, replace the toner cartridge.
  • The developer roller is defective. If a repetitive mark occurs every 2 inches (51 mm) on the page, replace the toner cartridge.
  • The charger roller in the toner cartridge is defective. If a horizontal black line occurs every 1 1/2 inches (38 mm), replace the toner cartridge.
  • The transfer roller has toner on it. If the defects occur every 2 1/6 inches (53 mm) on the black page, the problem will likely correct itself after a few more pages.

Improperly Formed Characters

If characters are improperly formed, producing hollow characters, your paper stock mat be too slick. Try a different paper.

If characters are improperly formed, producing a wavy effect, the laser scanner needs service. Call your authorized HP dealer or HP service representative

Vertical Line at Edge of Paper

If a vertical line appears on the page’s margin (usually the right margin) after printing about 10,000 pages, the drum in your toner cartridge is wearing out. The line will grow wider, with cross-hatching. Replace the toner cartridge. Shaking the cartridge will not temporarily relieve the problem.
