Maintenance
IMPORTANT: Don’t laminate one-of-a-kind documents unless you are sure of your laminating skills and can afford to damage or ruin the document.
Don’t laminate valuable items such as stamps, baseball cards, autographs or other collectables because the value of such items can be destroyed by lamination. Collectors generally value these kinds of items only in their original state.
Remember that you cannot laminate thermal paper, such as typical fax paper, because it is activated by heat and will turn black. Also, remove paper clips and staples because they can damage the rubber rollers. Be careful about laminating anything that will be affected by heat. For example, the colors in crayon drawings may run together or be smeared, especially if the crayon layer is heavy. Light crayon drawings may not be affected, but test an expendable sample of any item that may not laminate well.

1-2 Features & Benefits
Your new laminator has several standard features that set it apart from other models.
∙The clear safety shield keeps fingers away from the head shoes and laminating rollers while allowing you to see your work.
∙The easily accessible heat control permits the use of many different types of thermal laminating film from 1.5 to 5 mil thick.
∙Ease of cleaning. The silicone rubber rollers and the Teflon-coated heat shoes of the laminator should be cleaned regularly
∙Tension control knobs are built into both supply roll mandrels so that wrinkles and curling in the film can be elimated.
∙Ease of maintenance. The Educator is made to last, however, some items on a laminator do wear out. Even the high-quality silicone rubber used in the rollers will lose flexibility over time. Extensive use may wear out the rollers on an operator may cut a roller by accident. Rollers and other key parts can be changed quickly without disassembling the frame.
∙Reverse can be invaluable at times to help avoid problems or clear misfeeds.
∙Silicone rubber laminating rollers are flexible enough to provide good edge seal and firm enough to offer a good surface seal. A high silicone content insures a much longer average roller life. They can accommodate poster board or other materials up to 1/8” thick.
∙Very strong steel cores prevent roller flexing and insure uniform pressure across the width of the laminate, giving you the best quality lamination available in mediumduty commercial machine.
∙Zippy safety cutter is shipped with the laminator to allow quick and easy cutting and trimming of the lamination web.
∙Removable power cord prevents unauthorized usage without locking away the whole machine.
∙100% made in the U.S.A.
1-3 Options
There are several options available to make the Educator more versatile.
∙Footage counter. This device can be reset to measure film usage in feet. Also available in a metric version. The footage counter and slitters will not fit on the machine together.
∙Slitters can automatically cut away side scrap which can greatly reduce the amount of time needed to trim your work. Most Educator-class laminators do not have slitters available. The slitter knives can be completely retracted into their holders when not in use.
∙Right side feed guide to go with the standard left side guide and feed on sheet at a time with greater accuracy or feed two sheets at a time in alignment with each other.
∙The dust cover will help keep the machine clean while not in use.

1-5 Principles of Operation
The laminator operates by pulling film with a thermally activated adhesive over a heat source and into a set of laminating rollers. Film from a supply roll passes over heat shoes to activate a polyethylene adhesive layer on the film. It then passes through rubber rollers to apply pressure and bond the film to the item being laminated. The film’s adhesive is pressed into the ink and fibers on the surface of the paper.
The strength of the lamination bond can be checked by cutting a large “X” on the surface of a laminated sample with a sharp blade. Use the tip of the blade to pry up one corner of the “X”. Grab that corner and pull up the film. Ink and/or paper fibers coming up with the layer of film indicates a good adhesive bond.
If the film comes up too easily, with no ink or paper, the lamination was probably done at too low a temperature. Check the instructions that may have come with your laminating film and/or the lamination chart in section 5-5.
Please note that when doing X-test on glossy (coated) paper, a good X-test will pull up ink only. The film should not come up easily. When laminating material that is not glossy (uncoated), the paper is often more fibrous and a good X-test will yield ink and paper fibers coming up with the film.
1-6 Laminating Film
Most thermal laminating film consists of two layers: a base of polyester and an adhesive layer of polyethylene. The polyester layer forms the harder outer surface of the film and does not melt at laminating temperature. It provides rigidity and protection for your laminated items. The greater the polyester content, the higher the level of protection, rigidity and luster. The polyethylene layer melts at laminating temperature and bonds the film onto the subject material under the pressure of the laminating rollers. As an X-test demonstrates, the adhesive is pressed into the paper and fills irregularities in the surface.
The proportion of polyester and polyethylene in a film is usually described with numbers. For example a “1-2” film consists of one mil of polyester and two mils of polyethylene. The first number refers to the base layer. The second number refers to the adhesive layer. A mil is 1/1000 of an inch.
Since polyester is the more costly of the two types of plastic generally used in laminating film, a “3-2” film will cost more than a “2-3” film. Both are 5–mil films but the “3-2” version will seem a little thicker on a piece of laminated material because it will be slightly stiffer. Thermal laminating films are available in many different base/adhesive combinations. Five-mil film, for example 1-4, 2-3, 3-2, and 4-1 combinations.
In the US laminating trade, the generally accepted practice is to describe two-sided lamination, or encapsulation, by the thickness of one layer of film. For example, “3-mil
lamination” should refer to lamination with two layers of 3-mil film. If you are buying or selling lamination film or lamination service, please make sure both parties understand the film descriptions being used.
There is a huge variety of thermal laminating films available to suit many different kinds of application. Here are some of the more commonly used “special” film types or film additives:
∙Film with low-melt adhesives, also known as co-polymer films; these often have better clarity and are less likely to curl or ripple.
∙Matte films to eliminate glare or to accept printing or accept printing or writing; many suppliers offer films with glossy and matte (non-glare) finishes.
Rolls of film may be purchased in different widths. The size of the laminator is the only limitation to the width of the film rolls you can use. The Educator can use 4, 12, 18, or 25 inch rolls. Make sure the upper and lower roll widths are the same, and are aligned with each other.
Rolls are also produced with different lengths of film on a roll (250’, 500’, 1000’). The Educator will easily accommodate film rolls up to 6” diameter.
When installing film, always center the rolls if film on the supply roll mandrels so the
core grippers engage the cardboard core. Look for the score marks around the supply rill mandrels to aid in aligning the top and bottom rolls.
We recommend 3-mil film for the most common applications, including posters, signs or instructional aids. The 3-mil film provides better protection, more rigidity, and a more lustrous appearance than 1.5-mil film. Five mil film is suggested for those applications that need the most protection and rigidity.
Lamination with 1.5-mil film can sometimes present problems because the film is so thin it loses heat easily. It sounds backwards, but 1.5-mil film has to be run at a higher temperature than a 3-mil film with the same adhesive. The higher temperature compensates for the faster rate of heat loss during lamination. A standard 3-mil film is applied at 280°F, while a standard 1.5-mil film must be applied at 310°F. Even when applied at 310°F, a 1.5-mil film is still more likely to delaminate later.
If the item being laminated is fairly thick, it will pull heat from the film. This will lower the temperature of the 1.5-mil film and prevent it from sticking properly. When laminating thick items with standard 1.5-mil film, it may be necessary to raise the temperature to 330°F or 340°F. Do not use any higher temperature for any film than is needed to get an acceptable degree of adhesion, as measured by an X-test. Remember there are low-temperature films that should run at much lower temperatures than those cited in this example. (see the chart on film operating temperatures.)
Rolls of film are sometimes spliced. Most film suppliers will mark a splice with colored tape. This way, you can see the splice as a “dash” of color on either end of the roll. If
you spot a spliced roll in advance, you can put it on the top supply roll mandrel in order to see the splice coming more easily avoid putting material under the splice. Or you could put it on the bottom roll if you plan to be laminating items that will never be seen from the back side.
