How to Clear Paper Jams?

November 10, 2009 0
Let us suppose that you've got deadlines to beat and reports to submit when suddenly in the middle of printing, the laser printer jams. In instances such as this one, the normal reaction would be to bellow in frustration and to vent one's anger on the equipment over the delay its malfunction has caused. But then such action is counter-productive. On the contrary, one must keep his cool and thresh out what ever triggered the paper jam in the first place.

There are several factors that could push a printer to jam. In most cases, the user have no control over it. Find below 2 of the most common causes of paper jams. For a more detailed discussion on the causes of paper jams, refer to our previous post Paper Jams: Why paper gets stuck inside the printer?
  1. Paper type, quality and moisture content that renders the media to crease easily

  2. Worn out rollers that have lost its tendency to pick-up and move paper in the course of printing
Clearing the Paper Jam
Always maintain a clear, focused mind when attempting to retrieve the paper from where it jammed and determine the best solution possible. Never rush when pulling out jammed paper because failure to retrieve the entire sheet could result into more serious problems once paper has been ripped into smaller pieces. Below are five steps adapted from PC Support Tips.com that could help the user clear paper jams.
  1. Initially pull out whatever paper is left with the printer intake and paper supply trays.
  2. New generation printers are supplied with removable paper intake trays. Pull out the paper tray for an easy inspection of the jammed section of the printer.

  3. Now remove the toner cartridge and drum unit from the printer. Doing this will provide easy access to the jammed paper.

  4. Open the printer's sheet-feed back door to inspect the extent of paper obstruction. This step is applicable for laser printers designed with a straight paper path.

  5. After discerning the nature of the paper jam, start pulling the jammed paper out gently. Consider applying force evenly on the entire width of the paper to avoid tearing. Remember that the entire sheet should be removed as a single piece.
After removing the jammed paper from the printer, check further for any debris (paper clips, staple wire, hair clips) that may have triggered the jam.

Before reloading the toner cartridge back to the printer, determine if the cartridge has sufficient toner supply. If not, then use a compatible toner refill kit to replenish toner supply. You have just completed clearing the printer of jammed paper, plug the printer back and start printing.

Paper Moisture Content: How it affects the integrity of printouts?

October 26, 2009 0

How does the moisture content of paper affect the quality of printouts? There's more to the use of transparencies in printing than getting them stocked for the next print job. In this regard, laser printers ought to dig this info.

Moisture content is a determining factor of print quality. Media with low moisture content has the tendency to curl and create paper handling troubles. On the other hand, high moisture content affects the adhesion of toner particles on paper that would likely result to poor quality printouts with smudges appearing on the printed page. There has got to be a reasonable balance between room temperature and humidity in order to obtain the type of prints desired.

What therefore is the ideal printing environment? A fully air-conditioned facility with room temperature that hovers from around 70 to 80 degrees Fahrenheit and humidity content that ranges from 35% to 55% is considered highly conducive to laser printing. Packed reams of paper pulled out straight from the factory have a set moisture content of about 5%, which happens to be ideal for use on the laser printer. However, paper could either lose or gain moisture content when stored in a less favorable environment for several months. The manner by which paper is stored contributes much to the print quality of outputs. Therefore when stocking media, make sure that the reams of paper in inventory is consumed within a 3 month period.

Find below some helpful tips relevant to the handling and storing of laser printer media which consequently affects the upkeep of ideal moisture content and the sustained quality of printed output.
  1. Conduct print jobs with locations exhibiting comfort zone ranges in terms of temperature, humidity and air movement because excessive heat causes paper to lose its moisture content through evaporation; or gain moisture if room humidity is a bit too high.
  2. Store paper in a dry (average temperature) bin; preferably its original packaging since manufacturers designed those to be moisture-proof.
  3. Avoid storing paper in damp environments so as to prevent paper from absorbing too much moisture. In time, this could render the paper soggy and no longer fit for use on laser printers.
  4. Open only reams that could possibly be used for the whole day. Never leave stocks of paper bare. As much as possible, insert stacks of unused paper back to its packaging and seal it, particularly during weekends.
  5. Before committing to the purchase of reams of paper for a 3-month period, always conduct a test print to ensure that paper is suited for the laser printer.
The American Society for Testing Materials (ASTM) is working with paper manufacturers to set the groundwork for an acceptable paper standard. Until then, laser printer users are left to fend for themselves.

Print defects do not always result from the use of an unspecified paper type, low toner supply can sometimes contribute to defects. In this case, refilling an empty cartridge with compatible toner supplied by a toner refill kit can resolve the issue.
