Solving Problems
Drying takes a while for 2-sided printing.
Solutions
For 2-sided printing, one side of paper is printed and dried, and then the other side is printed. Because
the drying time differs depending on the environment, such as temperature or humidity, or the print data,
the printing speed may be slower.
Printing Slows Down Dramatically During Continuous Printing
The function that prevents the printer mechanism from overheating and being damaged is
operating.
Solutions
You can continue printing. To return to normal printing speed, leave the printer idle for at least 30
minutes. Printing speed does not return to normal if the power is off.
Printing Is Too Slow While Using PostScript Printer Driver

Solutions
Set the Print Quality setting to Fast in the printer driver.
