Lexmark X748DE Printer User Manual


 
Fiber content
Most highquality xerographic paper is made from 100% chemically treated pulped wood. 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 can negatively affect paper handling.
Unacceptable paper
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 papers 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
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
Roughedged, 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)
Multiplepart forms or documents
Selecting paper
Using the appropriate paper prevents jams and helps ensure troublefree 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 to 90 g/m
2
(16 to 24 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 printed with heatresistant inks designed for use in xerographic copiers. The ink must be able to withstand
temperatures up to 190°C (374°F) without melting or releasing hazardous emissions. Use inks that are not affected by
the resin in toner. Inks that are oxidationset or oilbased generally meet these requirements; latex inks might not.
When in doubt, contact the paper supplier.
