Do not unplug the printer unnecessarily.

Do not unplug the printer or turn off a power strip to which the printer is attached when the printer’s power is turned on. This may prevent the BJ cartridge from returning to the home position on the right and being capped, which may cause the print heads to dry out. This is critical. If left uncapped, the print head units may clog and may need to be replaced.

Do not attempt to manually move the mechanism that holds the BJ cartridges. Attempting to move the BJ cartridge holders may damage delicate mechanical parts.

It’s a good idea to use a power surge protector. However, never turn off the printer using the power strip. Always use the POWER button on the printer.

Cleaning the Printer

Your printer requires little routine maintenance. Perform the following maintenance, as necessary, to keep your printer in good operating condition.

CBefore cleaning, make sure the printer is turned off and the power cord is unplugged.

Do not clean the exterior of the printer with volatile liquids such as thinners, benzene, or any spray-type or chemical cleaners; doing so will damage the surface of the printer.

When cleaning the printer, avoid the area near the print heads on the BJ cartridges. Do not touch the print heads. Ink may leak out and cause stains.

Clean the printer regularly to avoid printing problems. Remove any ink mist or paper debris from the interior of the printer using a soft cloth moistened with water.
