Important Points and Recommendations
• When plain paper is used in a low temperature environment (10
thickness level from 3 > 2.
• If wrinkling occurs on translucent paper with Mode 2 selected, select Mode 1.
• Fusing conditions can be affected by low temperature, humidity, the length of the print job, continuous
printing, etc. To improve toner fusing, shift the mode selections down: 3 > 2 > 1.
• To eliminate wrinkling or blurred images, shift the mode selection up: 3 > 4 > 5.
• If the selection is changed from Mode 1 or 2 for translucent paper to another setting (plain, film), the
machine may take longer (up to 2 minutes) to reach the copy ready temperature.
• During long print jobs, the interval between copies may increase. This slows down printing. The
machine does this automatically (CPM down) to maintain the correct fusing temperature.
Zero-Cross Control Test
Before the machine switches on the fusing lamp, the zero-cross control test determines whether the power
supply is 50 Hz or 60 Hz.
If the frequency does not fall in the necessary range after 10 attempts, then:
• If the frequency is too low, SC547 (Zero-Cross Signal Errors) occurs.
