Media 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 feed paper weights from 60 to 176 g/m

long. Paper lighter than 75 g/m performance, use 80 g/m in.), we recommend 90 g/m

• Curl—Curl is the tendency for paper to curl at its edges. Excessive curl 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 curling prior to printing and can cause feeding problems.

• Smoothness—Paper smooth ness direct ly affe cts p rint quali ty. If p aper is too ro ugh, to ner can not fus e to i t

properly. If paper is too smooth, it can cause paper feeding or print quality issues. 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 amou nt of m ois ture in pap er affects both print quality and the ability of the printer

to feed the paper correctly. Leave paper in its original wrapper until it is time to use it. This limits the exposure of paper to moisture changes that can degrade its performance. Condition paper before printing by storing it in its origin al wr apper in the same envi ronment as the printer fo r 24 to48 hours bef ore printi ng. Extend the time several days if the storage or transportation environment is very different from the printer environment. Thick paper may also require a longer conditioni ng period.

• Grain direction—Grai n refers to th e alignm ent of the paper fibe rs in a she et of pape r. Grain is either gra in

long, running the length of the pape r, or grain short, runn ing the width of the pap er. For 60 to 176 g/m to 47 lb bond) paper, use grain long fibers.

• Fiber content—Most high-q ual ity xe rogra phi c pa pe r is m ade from 100% chemically treated pulp ed w oo d.

This content provides the paper with a high degree of stability resulting in fewer paper feeding problems and better print quality. Paper containing fibers such as cotton possesses characteristics that can negatively affect paper handling.

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

Unacceptable paper

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

• Preprinted papers with chemicals that may contaminate the printer

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

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

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

• Recycled papers containing more than 25% post-consumer waste that do not meet DIN 19 309, and

weighing more than 80 g/m

• Paper weighing less than 80 g/m

(21 lb)

• Multiple-part forms or documents

Y112730-2

General information 1-13

Page 36

Selecting paper

Using appropriate paper pre vents jams and helps ensure trouble-free pri nting. To help avoid jams and poo r print quality:

• Always use new, undamaged pape r.

• Before loading pape r, k no w the rec om mended print side of the paper. This informati on i s usu al ly 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

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 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 emis sions. 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 (s uch as prem iu m c ott on p apers, 200–300 Sheffield units) have been engi nee red 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

1-14 Service Manual

Y112730-2

Page 37

Recycled paper, paper of lower weight (<60 g/m2 [16 lb bond]) and/or lower caliper (<3.8 mils [0.1 mm]), and paper that is cut grain-short for portrait (or short-edge) fed printers may have lower bending resistance than is required for reliable paper feeding. Before using these types of paper for laser (electrophotographic) printing, consult your paper supplier. Remember that these are general guidelines only and that paper meeting these guidelines may still cause paper feeding problems in any laser printer (for example, if the paper curls excessively under normal printing conditions).

The Code ROM or NAND flash failed the Cyclic Redundancy Check (CRC) check or the NAND experienced an uncorrectible multi-bit failure. “<loc>” indicates the source of the failure and has one of the followi ng values:

• CRC Failure: The source is a failing package indicated by Pn where “n” is the package number. This error could occur on a controller with ROM or NAND flash and could occur as a result of the CRC check done when the machine is powered on. The range of package number s is f rom 0 to

15.

• Error Correction Code (ECC) Failure: The source is a failing page indicat ed by Bn where “n” is the page number. Thi s error occurs only if a multi-bit failure is detected during the ECC execution . Sin gle bit failur es will be corrected automatical ly and will not re sult in a service error. The range of page numbers is from 0 to 1023.

Print quality—solid color page

Service tip: A solid color page is generally caused by a problem in the high-v oltage controller or an incorrect high voltage in the printing process resulting in toner development on the entire photoconductor drum.

Step Questions / actions Yes No

1 Replace the photoconductor unit (part of the

imaging unit). Remove the imaging unit and remove the developers. Place the original developers in the new photoconductor, and then replace the imaging unit. See “Imaging

unit (IU) removal” on page 4-40.

Does this fix the problem ? A faulty printhead can cause the problem. To

test the printhead for solid colors, place a narrow strip of p aper over the gap between t he developers. Make sure the paper stays in place when you replace the imaging unit. This will block the laser fr om discharging the photoconductor s. Print a Quality Test Page.

Does the page have a white vertical band? Check the high- voltag e contact from t he HVPS

to the photoconduc tor charge roll. Ensure the contact springs are properly mount ed and that the charge roll contact spring is making good contact with t he HPVS spri ng that runs thr ough the left printe r fram e. See “Toner cartridge

contacts” on page 4-59 to view the proper

mounting and for remov al procedures. Are the spring(s) def ective?

Turn the printer off, and check the contin uity of

the HVPS cable. Is there continuity?
