Selecting Paper; Selecting Preprinted Forms And Letterhead; Storing Paper; Using Recycled Paper And Other Office Papers - Olivetti d-Color MF920 Service Manual

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 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 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 to 176 g/m
•
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 200°C (392°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 200°C (392°F) without
melting or releasing hazardous emissions.

Storing paper

Use these paper storage guidelines to help avoid jams and uneven print quality:
•
For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40%. Most
label manufacturers recommend printing in a temperature range of 18 to 24°C (65 to 75°F) with relative
humidity between 40 and 60%.
•
Store paper in cartons when possible, on a pallet or shelf, rather than on the floor.
•
Store individual packages on a flat surface.
•
Do not store anything on top of individual paper packages.

Using recycled paper and other office papers

As an environmentally conscious company,Olivetti supports the use of recycled office paper produced
specifically for use in laser (electrophotographic) printers.
•
Low moisture content (4–5%)
•
Suitable smoothness (100–200 Sheffield units, or 140–350 Bendtsen units, European)
Note: Some much smoother papers (such as premium 24 lb laser papers, 50–90 Sheffield units) and
much rougher papers (such as premium cotton papers, 200–300 Sheffield units) have been engineered to
work very well in laser printers, despite surface texture. Before using these types of paper, consult your
paper supplier.
•
Suitable sheet-to-sheet coefficient of friction (0.4–0.6)
•
Sufficient bending resistance in the direction of feed
