To ensure the best print quality and the most reliable printer operation, follow these 
simple guidelines:

■

Use high-quality paper and only Tektronix transparencies and glossy 
coated paper.

■

Do not use any media designed for inkjet printers, especially inkjet coated 
paper and inkjet transparencies.  Inkjet media are coated with a substance 
that may damage the Fuser; Tektronix does not furnish service for damage 
or malfunction caused by the use of non-Tektronix supplies or 
consumables.  Tektronix coated paper and transparencies have been 
specially designed for use with Tektronix Color Laser Printers.

■

Double-sided printing and specialty media will require more frequent 
cleaning of the rollers and will reduce the average life of the consumables.

■

Auto-duplex only with laser bond paper that is 75 - 90 g/m

2

 (20 - 24 lb.).  

Do not use paper that is lighter than 75 g/m

2

 (20 lb.); it is not opaque 

enough for acceptable duplex prints.

■

Use only laser paper for automatic double-sided printing with the 
Duplex Unit. 

■

Keep the Imaging Unit’s light exposure to a minimum — less than 
90 seconds of artificial light and no exposure to sunlight  — or you may 
damage the unit:  

■

When installing a new Imaging Unit, keep the protective plastic sheet 
on until immediately before inserting the unit.  

■

If, when installing the Imaging Unit, you also need to install other 
components, install the Imaging Unit last to minimize its light 
exposure.

■

When changing a Toner Cartridge or clearing a media jam, make sure 
that you close the printer’s right side door quickly to avoid any light 
exposure to the Imaging Unit.

■

Do not leave the printer’s front door open for extended periods of time 
(for example, several hours).

■

Do not touch the underside or the right side of the Imaging Unit; 
fingerprints may appear on your output.

■

If your printer is a Phaser 740L printer (check the nameplate above the 
front panel display), make sure that you keep the light shield in place 
to protect the Imaging Unit.  Only remove the light shield when adding 
color to your printer.
