Color LaserWriter 12/600 PS Troubleshooting 2–4

Troubleshooting Checklist

Before troubleshooting the printer, make sure that you have checked the

following items in the order in which they are listed.

1 Make sure that the printer is on a ﬂat, sturdy surface and that it is

isolated from vibrations, direct sunlight, or environmental condi-

tions that do not meet speciﬁcation.

Caution

: It is extremely important that the printer be on a perfectly

level surface. Oil overﬂow errors can occur due to out-of-level

surfaces. See the “Leveling Instructions” addendum at the end of

this chapter for complete information.

2 Install the photoconductor cartridge and toner disposal box and

lower the disposal box cover.

3 Examine each cartridge and make sure that its inner workings are

locked and cannot turn within the cartridge housing.

Note

: If you can turn the inner housing to see the toner-coated

developing cylinder, the cartridge is not locked. Hold the cartridge

in your hands with the dark black inner housing facing up. Turn the

inner housing until it clicks into place and cannot turn any more.

4 Load each toner cartridge into its corresponding bay.

Note

: If you cannot install a cartridge, make sure that its sealing

tape is removed and that you are installing the cartridge according to

the instructions in the user guide. After you load the fourth

cartridge, advance the carousel manually another half-revolution to

assure that the fourth cartridge is installed correctly.

5 Make sure that the fuser oil bottle is installed and that the oil bottle

clamp is in an up position.

6 Load the cassette tray with paper that is approved for use in this

printer and install the cassette into the printer.

7 Raise the transfer drum lever and close the front door.

8 Close the pickup block door and fuser access door if they are open.

9 If you have just run EPOST, remove the loopback test plug from the

I/O controller board.

10 Plug in the printer.

11 If you are on-site with a Macintosh, connect the Macintosh to the

AppleTalk connector on the I/O controller board.
