• Preprinted papers that require a registration (the precise print location on the page) greater than ±2.4 mm
(±0.9 inch), 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/m
2
(16 lb)
• Multiple‑part forms or documents
Selecting paper
Using the appropriate paper prevents jams and helps ensure trouble‑free printing.
To help avoid paper jams and poor print quality:
• Always use new, undamaged paper.
• Before loading paper, know the recommended printable side of the paper. This information is usually indicated on
the paper package.
• Do not use paper that has been cut or trimmed by hand.
• Do not mix paper sizes, types, or weights in the same tray; 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/m
2
(16–24‑lb) paper.
• Use only forms and letterhead printed using an offset lithographic or engraved printing process.
• Avoid paper with rough or heavily textured surfaces.
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 your paper supplier.
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%)
• Suitable smoothness (100–200 Sheffield units, or 140–350 Bendtsen units, European)
