  • Page 45: Envelope Specifications

    This might be caused by paper that has been affected by environmental conditions. Envelopes might meet the general specifications listed in table 2-4 and still not print satisfactorily because of the printing environment or other variables over which HP has no control.

  • Page 46: Envelopes With Adhesive Strips Or Flaps, Envelope Storage

    Table 2-4. Envelope Specifications (continued) Description Specification Fusing Compatibility All inks, adhesives, and other materials used in the envelope must be compatible with the heat and pressure of the fusing process. Materials must not discolor, melt, offset, or release hazardous emissions when heated to 200 degrees Celsius (392 degrees Fahrenheit) for 0.1 second.

  • Page 47

    Envelopes with Double Side Seams Double side-seam construction has vertical seams at both ends of the envelope rather than diagonal seams. This style may be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope as illustrated below. Envelope Margins The following gives typical address margins for a commercial #10 or DL envelope.

  • Page 48: Label Specifications

    Label Specifications When selecting labels, consider the quality of each component: • Adhesives: The adhesive material should be stable at 200 degrees C (392 degrees F), which is the printer’s fusing temperature. • Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets with spaces between the labels, causing serious jams.

  • Page 49: Transparency Specifications, Storing Print Media

    Transparency Specifications Transparencies used in the printer must be able to withstand 200 degrees C (392 degrees F), the printer’s fusing temperature. To avoid damaging the printer, use only transparencies recommended for use in laser printers, and print transparencies to the top output bin.

  • Page 50: Shipping Print Media, Paper Fillers, Testing Media Specifications

    The following tests describe ways to qualify the media with respect to the specifications listed in this manual and the HP LaserJet Printer Family Paper Specifications Guide. See “Tools and Suppliers” (page 43) for help in obtaining tools needed to perform these tests.

  • Page 51

    Basis Weight Field Test The basis weight should be indicated on the ream label. If the label is not available, a simple field test can identify the basis weight of paper. The basis weight of paper is equal to the weight of 2000 sheets of paper, or 4 full reams.

  • Page 52

    Paper Weight Equivalence Table Use this table to determine approximate equivalent points in weight specifications other than U.S. bond weight. For example, to determine the equivalent of 20 lb U.S. bond weight paper in U.S. cover weight, locate the bond weight (in row 3, second column) and scan across the row to the cover weight (in the fourth column).

  • Page 53

    CAUTION: Never use the coarse adjustment end of the micrometer when measuring for caliper. The coarse adjustment will compress the paper fibers, resulting in an inaccurate reading. For example, if the fibers are compressed, 6 mil paper could measure as little as 3 mils. Always use the fine adjustment to measure caliper.

  • Page 54

    Envelopes should have a diagonal grain, which gives them the best stability. To determine this, cut a square section from one corner of an envelope. Wet this section and observe the manner in which it curls. Two opposite corners should curl toward each other. Figure 2-2 Long, Short, and Diagonal Grain Curl Curl Field Test...

    Cleaning Stage Figure 5-9 Cleaning the Photosensitive Drum At the cleaning stage, the photosensitive drum's surface is prepared to hold an image. During printing, the drum rotates completely several times per printed page. Before forming the image for a given section of print, a cleaning blade removes toner from the previous rotation of the drum.

  • Page 97: Writing Stage

    Writing Stage Figure 5-11 Laser Scanner System At the Laser Scanner, a laser beam focuses onto the photosensitive drum and discharges the drum's negative potential. This creates a latent electrostatic image, which later is developed into a visible image. A small laser diode beam shines onto a rotating, 6-sided mirror. As the mirror rotates, the beam reflects off the mirror and sweeps the page from left to right.

  • Page 98: Developing Stage

    Developing Stage Figure 5-12 Developing the Latent Electrostatic Image into a Visible Image At the developing stage, the latent electrostatic image is developed into a visible image on the photosensitive drum. The developing cylinder consists of a metallic cylinder that rotates around a fixed magnetic core inside the toner cavity.

  • Page 99: Transferring Stage

    Transferring Stage Figure 5-13 Transferring the Toner Image on the Drum Surface to the Paper At the transferring stage, the toner image on the photosensitive drum's surface is moved to the paper. The transfer roller applies a positive charge to the back of the paper, causing the paper to attract the negatively charged toner on the drum's surface.

  • Page 100: Fusing Stage

    Fusing Stage Figure 5-14 Fusing Film and Pressure Roller At the fusing stage, heat and pressure fuse the toner to the paper to produce a permanent image. The paper passes between a fusing film and a pressure roller. The fusing film melts the toner while the pressure roller compresses it into the paper.

  • Page 101: Paper Pick And Feed System

    Paper Pick and Feed System When the Formatter sends a print command to the Engine Controller Assembly, the main motor (M1001) and scanner motor start rotating and the fusing heater temperature control starts. The paper feed system automatically picks print media from either Tray 1, Tray 2, or Tray 3 if installed and delivers it to the registration roller.

  • Page 102: Paper Detection, Paper Size Detection, Paper Jam Detection

    Formatter illuminates the display’s LED until paper is added. Paper Size Detection The HP LaserJet 2100 printer does not contain a paper size detection mechanism; therefore, the printer cannot detect the size of paper set in the trays. The printer detects the paper size by measuring the time from when the top-of-page sensor (PS502) detects the leading edge of the page until the trailing edge of the page clears the sensor.

  • Page 146: Media Troubleshooting, Determine The Problem Source: Paper Or Printer, Isolate A Paper Path

    Media Troubleshooting Media defects cause both paper jams and image defects. If correcting the previously described conditions does not eliminate the printing problem, investigate the media as the source of the defect. Problems with paper are sometimes difficult to detect. Following a standard troubleshooting procedure may help isolate media-related problems.

    Hewlett-Packard neither warrants nor recommends the use of a particular brand of paper or print media. Media properties are subject to change by manufacturers and HP has no control over such changes. The customer assumes all responsibility for the quality and performance of media.

  • Page 149: Isolate A Paper Type

    Many pre-printed forms and special letterhead papers perform well in HP LaserJet printers. However, these papers undergo processes that alter their original characteristics and care must be taken to ensure they conform to HP specifications. All special papers should be wrapped in moisture-proof wrapping when purchased from the paper converter or printing house.
