General Cautions
Make sure that the Data In
indicator is off before unplugging the power cord.
While printing, do not turn off the main switch.
While printing, do not unplug the power cord.
While printing, do not open the door or covers.
While printing, do not move the machine.
Open and close all doors and covers carefully.
When printing onto paper that contains images on the back, make sure there is a 6 mm (0.24 inches) margin at the back leading edge. If there is no margin, the machine might wrongly detect that paper is wrapped around the drum and stop printing.
When you use envelopes or pasted print paper, the leading edge of the prints might be damaged.
Always make a few trial prints to check the image position because the image position of the trial print might not correspond with that of the original.
The leading edge of the prints might become stained if the edge touches the image of prints on the paper delivery tray.
Print ink on the paper delivery tray might stick to the back side of the next print.
Press the [Proof] key to perform a test print as the image density of the first few prints might be light.
When the machine is on and the power source is less than 90% of the specified amount, printing quality will decrease. Therefore, make sure the supply from your electrical outlet is at least 90% of the required amount.
When you make a lot of prints from a small image, ink might ooze out from the edges of the master, especially in high temperatures and when printing in two or more colors. In these cases, make a new master.
Remove the paper from the tray before relocating the machine. If you relocate the machine leaving the paper on the tray, reset the paper after the relocation. If the main switch of the machine is turned on without resetting the paper correctly, the sensor might be broken.
If the printed paper is stored for more than one day, the paper may become wrinkled. If this paper is used, wrinkles may also appear on the master. If the paper will be stored for more than one day, store it in its original wrapping paper or other protective covering.
Shadowing may occur if the printed image at the rear edge of the paper is a solid color, when the printing speed is set to 1. If this occurs, print the image with the printing speed set to 3.
If there are fine lines within 5 mm to 10 mm (0.2 to 0.4 inches) of the edge of the image, shadowing may occur.
Depending on the type of paper being used, speckles may appear within 5 mm to 10 mm (0.2 to 0.4 inches) of the edge of the image at around 1,000 prints.
When two or more sheets of paper feed at once, you can select whether the warning message is displayed or not. Set to [On] of the "Double Feed Warning" with User Tools. For details, see System Settings
.When two or more sheets of paper feed at once, set paper on the paper feed side plates securely. For details, see Preparations for Printing
.When paper misfeeds occur, select the proper paper type from [Feed Tray Paper Type]. For details, see System Settings
. If the problem persists, fan or turn the paper over.If the paper skews, make sure to set the paper feed side plates securely. For details, see Preparations for Printing
.Make sure originals on the exposure glass are correctly positioned and aligned with the scale.
If the edges of the paper are rounded, skewing might occur. Change the paper's orientation or replace.
If the paper becomes creased, check that the correct paper type is selected in [Feed Tray Paper Type]. For details, see System Settings
.If custom paper crease frequently, use the standard paper type.
Burrs on the end face of the paper may damage the master surface and leave scratches on it. If you continue using the same master for printing, the scratches may result in ink spots on or around the edge of the paper. If this is the case, place the paper upside down, and then create the master again.
If you continue printing with certain types of paper, the master surface may become dirty with paper powder. Accordingly, white spots may appear on the printed image. If this is the case, remove the paper powder or create the master again.
When custom size originals are printed, black bands may appear on the sprints. If this is the case, place an unused A3, 11 × 17 sheet of paper on the custom size original.
It may be difficult to detect the size of the original if:
There is a solid image at the top of the original.
The original is placed while the machine is initializing.
The original is placed after the exposure glass cover or ADF is quickly lifted and lowered.
The original is placed without lifting the exposure glass cover or ADF at least 30 degrees.
