Refer to the following information on how to replace.

When “Change Belt Unit” / “Install New Belt Unit” is displayed and the printing stops, replace the belt unit.

You can continue printing even after “Change Belt Unit” / “Install New Belt Unit” is displayed by opening and closing the front cover. However, it is suggested to replace the belt unit as it may cause damages.

When “Change Fuser Unit” / “Install New Fuser Unit” is displayed and the printing stops, replace the fuser unit.

You can continue printing even after “Change Fuser Unit” / “Install New Fuser Unit” is displayed by opening and closing the front cover. However, it is suggested to replace the fuser unit as it may cause damages or paper jams.

This error indicates that the belt unit needs to be replaced soon.

Reinstall the belt unit by the following procedure.

Follow the guidance on the device’s Operator panel or see Change Fuser Unit/Install New Fuser Unit for details on how to change your fuser unit.

Note

• The fuser unit is extremely hot. Do not touch it.

• Use extra care when handling the image drum (the green cylinder), because it is fragile.

• Do not expose the image drum to direct sunlight or strong light (About 1,500 lux or above).

• Do not leave it for more than 5 minutes even under room lighting.

Toner is powdered ink, and a toner container is called a toner cartridge.

An image drum is a unit that forms toner images. It has a green tube on the bottom. Handle with care, and do not touch or damage this part.

The image drum is located under the toner cartridge and is integrated with the toner cartridge.

If toner adheres to the window film of the image drum, gently wipe it off with a dry soft tissue.

Clean the paper feed rollers if paper jams occur frequently.

Note: You should replace the paper feed rollers if paper jams keep occuring after cleaning them.

Your printer has two built-in trays (tray 1 and the MP tray). Refer to the list below to check the supported paper and capacities of each tray.

For high-quality printing it is necessary to use paper that satisfies conditions regarding quality, thickness, paper finish, etc. If printing on paper not recommended by Crio, thoroughly test the print quality and paper traveling performance, etc., and check that there are no impediments before use. If using a (paper) medium that is curled or wrinkled before printing, print quality and paper traveling performance cannot be assured.

Store paper under the following conditions to maintain quality.

• Inside a cabinet or other dry and dark place
• On a flat surface
• Temperature: 20°C
• Humidity: 50% RH (relative humidity)

Do not store in the following locations:

• Directly on the floor
• In direct sunlight
• Near the inside of an exterior wall
• On an uneven surface
• Where static electricity may be generated
• In places that are excessively hot or where temperature rapidly changes
• Near a copier, air conditioner, heater, or duct

Note:
Do not unwrap the paper until you are ready to use the paper.
Do not leave paper unwrapped for a long period. Doing so may result in paper handling and print quality issues.
Depending on media used, usage conditions and a storing conditions, a decrease in paper quality or curling of the paper may occur.

Use PS driver for Mac OS X.14 or Earlier Version and need Printer Driver Updater (PS) for macOS 10.15

MacOS is supported by the printer, but need Printer Driver Updater (PS) for macOS 10.15 or later. RIP software is not compatible with Mac.

Crio is compatible with Mojave. When you use macOS Mojave 10.14, if the image is printed like mosaic, please use PS driver updater. RIP software is not compatible with Mac.

Windows 10 and newer.

Follow the guidance on the device’s Operator panel.

Set the lever of the toner cartridge of the color indicated in the message displayed on the operator panel to the correct position by the following procedure.

This error indicates that the belt unit is not properly installed to the printer.
