Notes
The consumable requirements listed in the table are based on the following
conditions:
Printer output per month (12" length/375 mm width):
3,000,000 pages for VarioStream 8550
3,500,000 pages for VarioStream 8650
4,000,000 pages for VarioStream 8750
Toner consumption is dependent on ink coverage. If 100% of the possible
characters are printed on a form of 12" length/375 mm width, then the toner
consumption increases from 48 g per 1000 sheets to approximately 240 g per
1000 sheets. The option of setting the contrast on the operator panel to a lower
level allows toner consumption to be reduced by up to 50%.
Average power-on time per month: 600 hours
Maximum stop rate per 200 forms 1 stop of 10 s duration
Coverage is 16% of the maximum printable characters at 1/10" column spacing
and 1/6" line spacing
Different operating conditions can lead to shorter service life, i.e. higher usage
(roughly 20–30%).
Toner and developer storage: Always store in a cool (< 35
well-ventilated room. Never expose toner and developer to direct heat (sunlight,
heaters, etc.)
