Before calling a repair technician for your HP LaserJet printer problems, try these simple fixes.

Do you want to cut service costs on your HP LaserJet printers? Who doesn’t? Here are some common problems and solutions to fix them.

Problem #1: Toner does not stick to the page or smears.

Solutions: The fuser assembly may be defective or it’s at the end of its life. The solution is to replace the fuser. The fuser is considered a consumable and can be replaced simply referring to the owner’s manual. Or, you may have a defective toner cartridge. Simply replace the cartridge and see if this fixes the problem. Also, toner may have spilled into the printer and may just need to be cleaned out.

Problem #2: Paper Jams.

Solutions: This can be caused by dust, grime or dirt has made its way into the printer.  Other causes could be worn rollers or the wrong paper type is being used. Periodically clean the printer and check the user’s manual to make sure that the paper being used is recommended by the manufacturer. If the paper you are using is too light or too heavy, paper jams can occur.

Problem #3: Printer is displaying a 50.4 error message.  This indicates a problem with the power supply.

Solution: If the printer is plugged into a UPS or a power strip, unplug it and plug the printer directly into the wall outlet. A laser printer should never be plugged into a UPS because of the power surges required by the printer. These surges are required by the printer to keep the fuser assembly warm.

Problem #4: Trouble printing envelopes.

Solutions: Envelopes can cause problems for laser printers. Choose envelopes that are close to 20 lbs. paper in weight and thickness. Also, make sure that the adhesive on the envelope is capable of withstanding the heat that the fuser puts out to keep the printing on the page. If you don’t, the envelopes will come out of the printer already sealed. If envelopes are coming out of the printer wrinkled, they may be too stiff for the paper path. Open the rear of the printer and let them exit at that location.

Problem #5: Part of or the entire printed page is faded.

Solutions: There are usually three conditions that cause this problem. The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge. Make sure the Economode is turned off.  Run a self-test and look at the settings for print density. You may want to increase the settings.

Problem #6: Printer is displaying a 79 error.

Solution: A 79 error can be the result of a problem with the network print server that services the printer. When troubleshooting a 79 error, first open the printer folder from the start menu on the print server to make sure there are no jobs pending. A 79 error can also indicate a failure of a printer add-on component, such as an MIO card or a RAM module. All add-ons should be removed and then added back to the printer one by one to determine which module may be at fault.

Problem #7: Can’t find a driver for a particular operating system.

Solutions: As new operating systems are released, new drivers need to be loaded for your exiting printers. It is best to consult the owner’s manual and find out what printers the drivers will emulate. While not all of the functionality of the printer will be available under the emulation, at least basic printing will work. Most HP printers will print with the HP LaserJet II driver installed, although specific options, such as duplexing, will not work.

Problem #8: Printer is not printing from the expected tray.

Solution: Look in two places to correct this particular error. First, look on the printing PC.  If the application is set to print to the wrong paper tray, correct it with the application by clicking on “Print Properties” and find the tray selection source. Second, check the printer. Make sure that the paper size on the control panel matches what is actually in the paper tray.

Problem #9: Ghosting (This is an issue when image prints correctly, but a much lighter copy also prints elsewhere).

Solutions: This could be due to a bad power outlet. Plug in another printer to the same outlet to see if the same thing happens. If it does, have an electrician check the voltage in the outlet and correct the problem. Another cause could be the drum or the imaging kit is near the end of life. To correct this problem install a new preventative maintenance kit, which includes an imaging kit and drum.

Problem #10: Printer picks up all the paper from the manual feed tray rather than one sheet.

Solutions: The pad that is responsible for separating the paper has likely worn out and needs to be replaced. It is also possible that the paper is wet due to humidity. Make sure the paper is properly stored and that it is “fanned” before putting it into the printer.

Hi-tech manufacturing is extremely complex and ever evolving. Technology changes at the speed of light these days and so hi-tech producers need their systems to be able to keep up with the production requirements accordingly within its infrastructure. Selling shelf life and design cycles are now averaging a mere 12-18 months at most. And with every new design or product enhancement, there is a need at that production level to modify and factor in the changes in the product manufacturing process.

All these products have a wide array of small parts and components that amalgamate together to create the new products. High amounts of detail on each of the components are required to begin at the point-of-assembly. This is needed in order to meet the demands to protect brand image and provide higher levels of customer service in regards to quality effective replacement service, as well as have a comprehensive understanding of what is impacting product failure rates and service issues.

Every part and component needs to be defined and identified in a database with its serial number and date of manufacture, during its entire product lifecycle -- so it can tracked and traced for access within the production and distribution systems, and then by field service techs and customers if repair or warranty, or product recall issues arise. It is impossible to provide effective customer service without it. Simply put … unhappy customers cause decreased demand, causing poor sales and a diminished brand image.

For the manufacturer, when components are traceable, data is readily available to pinpoint fall-out rates early in the cycle. Thus, making it easier to adjust production output levels and have the right inventory on hand to meet the timely demands for hot swaps and swap-outs to reflect in-service life, and warranty stock, and service and replacement, and non-serviceable parts.

Thermal printheads are a vital part and extremely sensitive and expensive. Important care and maintenance is important to the optimal functioning.

Below are a collection of questions and answers to help provide you with information and direction to follow to get the most out of your printheads :

1. Why is preserving the printhead life important?

  • save money as printheads are very expensive
  • reduce poor print quality and marginally scannable bar codes, due to worn out printheads

2. What causes wear to the printhead ?

  • friction
  • prolonged use at high printhead energies (i.e. heat)
  • excessive buildup or ink residue on the printhead
  • misuse or abuse by the operator

3. What protects the printhead from abrasion?

  • a thin, hard coating over the heating elements protect them from abrasion while providing efficient heat transfer
  • the ribbon also protects the printhead from abrasion damage. It is separates the printhead from the printing substrate to shield it from abrasive movements, and also has a lubricated backcoat that allows it to flow smoothly over the printhead

4. What causes abrasive damage to printheads ?

  • when a label or tag stock is wider than the ribbon (which causes the media on either side of the ribbon’s edges passes directly over the printhead ).
  • using a ribbon with an ineffective backcoat
  • using inappropriate media for thermal transfer
  • improper cleaning of the printhead
  • some ribbons with backcoats specially formulated to clean the printhead

5. How can abrasive damage be recognized?

  • the first sign is usually a decrease in image quality
  • also can be failure of one or more heating elements, which shows as a “white line” through the printed image where the printhead no longer has the ability to transfer ink

6. Do quality ribbons require lower energy settings?

  • yes, a ribbon and substrate combination that is matched for optimum print quality at the lowest energy settings can extend printhead life

7. What is "Printhead Buildup"?

  • buildup is the accumulation of deposits of ink, ribbon backcoat, paper particles, label adhesive, dust, dirt, etc. over time

8. When does printhead buildup become a problem?

  • buildup becomes a problem when maintenance guidelines are not followed and print quality results
  • any deposit on the printhead , if not removed regularly, can insulate the heating elements from the ribbon and thus require printing at higher energy settings, which can ultimately shorten printhead life
  • burned-out pixels in the printhead result in unscannable bar codes

9. How to prevent buildup from becoming a problem?

  • purchase a good quality ribbon and printing substrate
  • minimize the accumulation of dust by keeping the printer cover closed
  • follow the OEM’s recommended operating, maintenance, and printhead cleaning schedule

10. How long will a printhead last if the best possible ribbons are used?

  • this will depend on the printhead design and other factors such as printer speed, energy settings, static, substrate, and ribbon quality
  • a good ribbon should be guaranteed not to cause significant degradation due to buildup or abrasion throughout the printhead’s rated life
  • the industry standard is that the printhead should last for one million linear inches of use
