Replacement of Replacement of toner cartridgetoner cartridge

I. Because these is not OPC protecting

shutter, picture is affected by OPC light

fatigue. Don’t open the right cover for a

long time.

II. Although Toner Cartridges are equipped at

each color space, caution message could be

displayed by CRUM information.

III. When toner cartridge replace, PTB belt could

be damaged.

PTB Unit Release Lever

I. Using the handle, Completely open the access

door.

II. Press the green release button on the inside

of the access door to release the transfer belt.

III. Holding the handle on the transfer belt, lift the

used transfer belt out of the printer.

IV. Take a new transfer belt out of the package.

V. Remove the paper covering the transfer belt by

removing the tape.

VI. Holding the handle on the new transfer belt, align

in with the slots on the inside of the access door.

Push down until it clicks into place.

VII. Then lower the transfer belt until it is parallel with

the access door and firmly seated.
