4602 Locate the serial number. Selecting paper Paper guidelines Use the appropriate paper to prevent jams and help ensure trouble‑free printing. • 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.
Page 30
4602 Smoothness Paper smoothness directly affects print quality. If paper is too rough, toner cannot fuse to it properly. If paper is too smooth, it can cause paper feeding or print quality issues. We recommend the use of paper with 50 Sheffield points.
Page 31
4602 Storing paper Use these paper storage guidelines to help avoid jams and uneven print quality: • Store paper in its original wrapper in the same environment as the printer for 24 to 48 hours before printing. • Extend the time several days if the storage or transportation environment is very different from the printer environment.

4602 Service tips • Do not touch the surface of the photoconductor drum with your bare hand. The oil from your skin may cause a charge disparity on the surface, and the toner may no longer stick properly. The result can be repeating blotches or voids on the printed page or patches of light print.

• Sharp and hard objects can damage the transfer roller surface. Be careful when using a screwdriver or prying tool near the transfer roller. If the transfer roller has tears or cracks, then the transfer roller may need to be replaced.

4602 Fuse Fuser Paper Even if the toner image is already on the paper, the toner particles are not yet permanently bonded to the surface. Paper is transported from the transfer roller to the fuser where heat and pressure are applied to it. As a result, the toner particles melt and permanently fuse with the paper, completing the print process.
4602 Printer paper path One‑sided print job Photoconductor drum Developer roller First input roller MPF pick roller Second input roller Pick roller Separator roller Transfer roller Fuser roller Fuser exit roller Paper exit roller The pick roller picks and feeds the paper to the separator roller. The separator roller feeds the paper to the second input roller, which feeds it to the first input roller.

4602 After printing, the printer ejects the paper by the paper exit roller. Two‑sided print job Paper exit roller Duplex rear roller Duplex front roller Second input roller After the first side is printed, the paper reverses direction to get its opposite page printed. The paper travels along the duplex path until it reenters the second input roller.
