Using recycled paper and other office papers

Recycled office paper produced specifically for use i n laser (electrophot ographic) print ers may be used in your printer. However, no blanket statement can be m ade that all recycled paper wi ll feed well.

Generally, the following property gui delines apply to recycled paper.

• Low moisture content (4–5%)

• Suitable smoot hness (100–200 Sheffield units, or 140–350 Bendt sen units, European)

Note: Some much smoother papers (such as premium 24 lb laser papers, 50–90 Sheffield units) and

much rougher papers (such as pr em ium cotton papers, 200–300 Sheffield units) have been engineered to work very well in laser printers, despite surface texture. Before using these types of pap er, consult your paper supplier .

• Suitable sheet-to-sheet coefficient of frict ion (0.4–0.6)

• Sufficient bending resistance in the direction of feed

Recycled paper, paper of lower weight (<60 g/m paper that is cut grai n-short for portrait (or short-edg e) fed printers may have lower bending resistance than is required for rel iable paper feeding. Before using these types of paper for laser (elect rophotographic) printing, consult your pape r supplier. Remember that these are general guidelines only and that paper mee ti ng these guidelines may still cause paper feedi ng problems in any laser pri nter (for example, if the paper curls excessively under normal printing conditions).

Paper guidelines

Paper characteristics

The following paper characteristics affect print quality and reliability. Consider these characteristics when evaluating new paper stock.

Weight—The printer can automatically fe ed paper weights from 60 to 162l7 g/m Paper lighter than 60 g/m performance, use 75 g/m we recommend 90 g/m

Note: Duplex is supported only for 63 g/m Curl—Curl is the tendency for paper to curl at its edges . Exce ssive cur l can cause paper feeding problems. Curl

can occur after the paper passes through the printer, where it is exposed to high temperatures. Storing paper unwrapped in hot, humid, cold, or dry conditions, even in the trays, can contribute to paper curl ing prior to printing and can cause feeding problems.

Smoothness—Paper smoothness directly affects print quality. If paper is too r ough, toner cannot fuse to i t properly. If pape r is too smooth, it can cause paper fe eding or print quality i ssues. Always use paper between 100 and 300 Sheffield points; however, smoothness between 150 and 200 Sheffield points produces the best print quality .

Moisture content—The amount of moisture in paper affects both print quality and the ability of the printer to feed the paper correctly. Leave paper in i ts original wrapper unti l it is time to use it. This li mits the exposure of paper to moistur e changes that can degrade its performance.

(16 lb) might not be stiff enough to feed properly, causing jams. For best

(20 lb bond) grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 in),

(24 lb) or heavier paper.

–170 g/m2 (17 lb–45 lb bond) paper.

(16 to 43 lb bond) grain long.

Condition paper before printing by st oring it in its original wrapper in the same envi ronment as the printer for 24 to 48 hours before printing. Extend the time several days if the storage or transportati on environment is very different from the printer environment. Thick paper may also require a longer conditioning period.

General information 1-13

7526

Grain directio n—Grain refer s to the alignment of t he paper fibers in a sheet of paper. Grain is either grain long,

running the length of the paper, or grain short , running the width of the paper. For 60 to 135 g/m bond) paper, grain long paper is recommended. For papers heavier than 135 g/m

Fiber content—Most high-quality xerographic pap er i s mad e from 100% chemically treat ed pulped wood. This content provides the paper with a high degree of stability result ing in fewer paper feeding probl em s and better print quality. Paper containing fibers such as cotton can negatively affec t paper handling.

, grain short is recommended.

(16 to 36 lb

Unacce p tab l e p aper

The following paper types are not recommended for use with the printer:

• Chemically treated papers used to make copies without carbon paper, also known as carbonless papers,

carbonless copy paper (CCP), or no carbon required (NCR) paper

• Preprinted papers with chemicals that may contaminate the printer

• Preprinted pap ers that can be affected by the temperature in the printer fuser

• 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 Note: In some cases, registrati on can be adjusted with a softwa re application to suc cessfully print on these forms.

• Coated papers (era sable bond), syntheti c papers, thermal papers

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

• Recycled papers t hat f ail EN12281:2002 (European)

• Paper weighing less than 60 g/m

(16 lb)

• Multiple-part forms or documents

Selecting paper

Using appropri ate paper prevents jams and hel ps ensure trouble-free printing. To help avoid jams and poor pri nt quality:

• Always use new, undamaged paper.

• Before loading paper, know t he recommended print side of the paper. This inf ormation is usually indicat ed

on the paper package.

• Do not use paper that has been cut or tri mm ed by hand.

• Do not mix paper sizes, types, or weights in the same source; mixin g 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 90 g/m

(16 to 20 lb) weight 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 print ed wit h heat-resistant inks designed for use in xero graphic copiers. The ink mu st be abl e to withstand tempe ratures up to 190°C (374°F) wit hout melting or releasing hazardous emissions. Use inks that are not affected by the resin in t oner. In ks that are oxid ation- set or oi l-bas ed general ly meet thes e requir ements; latex inks migh t not. When in doubt, contact the paper supplier.

Preprinted pap ers such as letterhead must be able to withstand temperat ures up to 190°C (374°F) without melting or releasing hazardous emissions.

1-14 Service Manual

7526

Storing paper

Use these paper stor age guidelines to help avoid jams and uneven print quali ty:

• For best results, store paper where the temperature is 21°C (70°F) and the rel ative humidity is 40%. Mos t

label manufact urers recommend printi ng 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.
