Notes:
To ensure consistent print quality, the toner cartridges and imaging units for many models of
equipment are designed to cease functioning at a predetermined point.
Grayscale images printed with the composite black setting increment the color pages counter,
because color consumables are used. Composite black is the default setting on most printers.
Controlling Print Quality
Various factors can affect the quality of the output of your printer. For consistent and optimum print
quality, use paper designed for your printer, and correctly set the Print-Quality Mode and Color
Adjustments. Follow the guidelines in this section to maintain optimum print quality from your printer.
Temperature and humidity affect the quality of the printed output. The guaranteed range for optimal
print quality is: 15–28ºC (59–82ºF) and 20–70% relative humidity.
