Basics LaserWriter Safety - 7 LaserWriter Safety 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.
Basics LaserWriter Safety - 8 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.
Basics LaserWriter Safety - 9 Select 360 stops when the paper cassette is removed. Weight LaserWriter printers are heavy. When lifting or moving the printer, be careful not to strain your back.

K Service Source Troubleshooting LaserWriter Select
Troubleshooting General - 1 General 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 Troubleshooting Tips Multimeter Probes 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.
Troubleshooting Service Test Page - 3 Service Test Page 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 "TestReady Configuration" in this chapter.
Troubleshooting Test-Ready Configuration - 5 Test-Ready Configuration 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.
Troubleshooting 310/360 Power-On Self Test - 7 310/360 Power-On Self Test 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.
Troubleshooting 310/360 Power-On Self Test - 8 • Finally the Jam LED extinguishes when no errors are found in the engine. In a functional printer, control will be passed on to the PostScript interpreter at the end of this sequence.
Troubleshooting 360 Printer Diagnostic - 9 360 Printer Diagnostic Note: Only the LaserWriter Select 360 offers diagnostic LEDs. Switch off the LaserWriter Select 360 printer, and remove the jumper from JMP1 on the I/O controller if a jumper is present. Set the mode switch on the printer's back panel to 9. The reporting sequence (which repeats continuously) is as follows: • All LEDs are on for 1 second. • All LEDs are off for 1 second. • The LED(s) that indicates the error is on for 1 second.
Troubleshooting 360 Printer Diagnostic - 10 I/O Controller Error SIMM Error* Engine Controller Error Fuser Error Laser Error Engine Error * A SIMM error can result from insufficient memory. You must have a minimum of 7 MB of RAM installed.
