LaserWriter Safety - 7 |
|
|
|
|
Unplug Printer
LaserWriter printers operate at high voltages. To prevent serious injury, always switch off the printer and unplug the AC power cord before servicing the printer.
Laser Beam Safety
Never remove the cover of the laser/optic assembly or disconnect the beam-detect cabling when the printer is switched on. Although the reflected laser beam is invisible, direct exposure to it can permanently damage your eyes.
Never disassemble the laser/optical assembly, whether the printer is powered on or not. The laser diode and focusing lenses are factory-aligned.

|
|
|
Fuser Heat |
|
|
The fuser assembly rollers become very hot during printer |
|
|
operation. Before servicing the fuser assembly, switch off |
|
|
the printer for at least 5 minutes to allow the fuser |
|
|
assembly rollers to cool. |
|
|
Toner Safety |
|
|
Toner is a nontoxic substance composed of plastic, iron, and |
|
|
a small amount of pigment. Clean skin and clothing by |
|
|
removing as much toner as possible with a dry tissue and |
|
|
then washing with cold water. Hot water causes toner to jell |
|
|
and permanently fuse into clothing. Toner attacks vinyl |
|
|
materials, so don't allow toner to contact vinyl. |

Troubleshooting |
General - 1 |
|
|
Troubleshooting contains quick-reference troubleshooting information for the LaserWriter Select. We encourage you to review and print out this chapter before troubleshooting a printer.
At the end of this chapter are troubleshooting flowcharts and tables. If a table name clearly addresses your problem, you can go directly to that table. If not, you should go to the flowchart associated with the version of the printer you are working on.
Troubleshooting |
Troubleshooting Tips - 2 |
|
|
When taking voltage and resistance readings, you will need to use special multimeter probes. The connectors within the LaserWriter Select are very small and require sharp needlepoint probes to make good contact. Do not use probes that do not make proper contact.
To prevent possible overheating, do not run the LaserWriter Select 360 printer for longer than 10 minutes with the covers removed, and be sure to keep all vents clear.
Troubleshooting |
Service Test Page - 3 |
|
|
The LaserWriter Select service test page consists of a line matrix. The LaserWriter Select printers produce a service test page when you jumper the two pins at connector P32 on the DC controller board. The test page confirms print engine operation.

Troubleshooting |
Service Test Page - 4 |
||
|
|
||
|
If the I/O controller mount is installed, you can access P32 by |
||
|
inserting the straightened end of a paper clip through the small |
||
|
access hole in the rear face of the I/O controller mount. |
||
|
Caution: If you want to run a service test page while the printer |
||
|
is in an open test-ready state, you must manually actuate the |
||
|
delivery sensor, otherwise a paper jam will occur. See "Test- |
||
|
Ready Configuration" in this chapter. |
||
|
|
|
|
|
|
|
|
Troubleshooting |
Test-Ready Configuration - 5 |
|
|
Paper delivery sensor PS201 is connected to the I/O controller mount. When you remove the mount to troubleshoot inside the printer or to run a service test page, you must reconfigure the sensing system to simulate an operational printer.
Troubleshooting |
Test-Ready Configuration - 6 |
||
|
|
||
|
To reconfigure the sensing system, remove the I/O controller |
||
|
mount and set it at an angle on top of the power supply. Position |
||
|
the mount so that connector P32 on the DC controller board is |
||
|
accessible. |
||
|
Insert a folded piece of paper into the U of sensor PS201, and |
||
|
make sure that the two cables are securely attached to the I/O |
||
|
board. If you need to communicate with a Macintosh, you can do so |
||
|
by reconnecting the serial connector. |
||
|
Caution: Jumpering connector P32 initiates a service test page. |
||
|
If the printer is in a test-ready configuration, you must manually |
||
|
actuate this sensor as paper hits the delivery sensor actuator |
||
|
within the fuser assembly. |

Troubleshooting |
310/360 Power-On Self Test - 7 |
|
|
The LaserWriter Select 310 and 360 go through a self diagnostic each time that you switch the printer on. This diagnostic is called the Power-On Self Test (POST). POST does not occur on the LaserWriter Select 300 printer.
Note: This test is not the same as the engine diagnostic (see next topic). Unlike the engine diagnostic test, POST does not require the placement of any loopback cable.
Observing how the LEDs extinguish from that point can help isolate certain failure areas.
•The Ready LED extinguishes when no errors are found on the I/O controller board.
•The Paper-Out LED then extinguishes when no errors are found on the RAM card.
