Ribbon Information
The MF8i ribbon is designed to provide hundreds of pages of use. However, the ribbon is a
consumable item and should be replaced often.
• If the printer begins jamming consistently, replace the ribbon.
• If the printing becomes light in color on the top copy, replace the ribbon.
• If the smear guard is damaged or lost, replace the ribbon.
Temperature
Although the printer is rated to print at low temperatures, ribbons are susceptible to cold
temperature. The ink in the ribbon will begin to crystallize if the temperature is below 32°F or
0°C, causing the first copy to have light print. To prevent this, the printer will automatically
enter into a low temperature printing mode when below this temperature. This mode reduces
the print speed to compensate for the temperature and the ribbon crystallization. The printer
will automatically exit the low temperature printing mode when the temperature is above
41°F or 5°C.
