Paper and specialty media guidelines 128

•Preprinted papers that require a registration (the precise print location on the page) greater than ±2.3 mm (±0.9 in.), such as optical character recognition (OCR) forms

In some cases, registration can be adjusted with a software application to successfully print on these forms.

•Coated papers (erasable bond), synthetic papers, thermal papers

•Rough‑edged, rough or heavily textured surface papers, or curled papers

•Recycled papers that fail EN12281:2002 (European)

•Paper weighing less than 60 g/m2 (16 lb)

•Multiple‑part forms or documents

Selecting paper

Using appropriate paper prevents jams and helps ensure trouble‑free printing.

To help avoid jams and poor print quality:

•Always use new, undamaged paper.

•Before loading paper, know the recommended print side. This information is usually indicated on the package.

•Do not use paper, paper labels, or card stock that has been cut or trimmed by hand.

•Do not mix sizes, types, or weights in the same source; mixing results in jams.

•Do not use coated papers unless they are specifically designed for electrophotographic printing.

Selecting preprinted forms and letterhead

Use these guidelines when selecting preprinted forms and letterhead:

•Use grain long for 60–90 g/m2 (16–24 lb) paper.

•Use only forms and letterhead printed using an offset lithographic or engraved printing process.

•Avoid papers with rough or heavily textured surfaces.

Use papers printed with heat‑resistant inks designed for use in xerographic copiers. The ink must be able to withstand temperatures up to 230°C (446°F) without melting or releasing hazardous emissions. Use inks that are not affected by the resin in toner. Inks that are oxidation‑set or oil‑based generally meet these requirements; latex inks might not.

When in doubt, contact the paper supplier.

Preprinted papers such as letterhead must be able to withstand temperatures up to 230°C (446°F) without melting or releasing hazardous emissions.

Using recycled paper and other office papers

As an environmentally conscious company, Lexmark supports the use of recycled office paper produced specifically for use in laser (electrophotographic) printers. In 1998, Lexmark presented to the US government a study demonstrating that recycled paper produced by major mills in the US fed as well as non-recycled paper. However, no blanket statement can be made that all recycled paper will feed well.

Lexmark consistently tests its printers with recycled paper (20–100% post-consumer waste) and a variety of test paper from around the world, using chamber tests for different temperature and humidity conditions. Lexmark has found no reason to discourage the use of today's recycled office papers, but generally the following property guidelines apply to recycled paper.

•Low moisture content (4–5%)
