Laserwriter 12/640 PS

Are you sure it's not the misalignment light that is permanently on?

Hello,

The most common cause of this type of Phantom paper jam is worn pickup rollers and separation pads in the paper trays. When these rollers get worn the gripping surface can not grab the paper correctly so no paper is fed into the printer and the printer gives the paper jam error. The rollers are very easy to replace, it takes about 20 minutes total. Here is a link to more information about the roller maint kit:

hi,

please clean all rubber rollers and pick-up rollers also. Also check the paper motor.

Look again and make sure NOTHING was left in the printer. Also make sure all access panels are completely closed.

Please make sure that the printer is working okay if directlysd connected to the MAC computer. You may try this as well. hope this helps

Description
LPR (line printer remote) is a platform independent printing protocol that is associate with TCP/IP. It works by using LPR client software that communicates to a server running LPR services.

In terms of PSU, LPR printing will become the basis for all network printing while Novell print queues are phased out. Therefore, all Macintosh, Windows, and Unix computers will be configured to print through LPR.

Requirements

· The name of LPR print queue. This can be found by searching the LPR printer database.

· LaserWriter print drivers version 8.5.1 or newer

· The Macintosh must have a working TCP/IP networking configuration. (If the Mac can browse the web then it's working.)

· a server running LPR services or a printer that supports LPR printing. Most HP LaserJet printers support LPR. However, only the following LaserWriters support LPR printing:

- LaserWriter 8500
- LaserWriter 16/600 PS
- LaserWriter 12/640 PS
- Color LaserWriter 12/600 PS
- Color LaserWriter 12/660 PS Procedure

Hello,

It's the sensor from tray fault. Try to blow with air spray to sensor, maybe is dirt with paper dust and need clean.

All the best and Happy New Year !

I had the same problem when I got a new computer with Vista. I just went through the available 600 DPI printer drivers until I found one that worked ok with the 12/640 printer. The driver I used was the Samsung 6000 PS. I have had no problems with it.

I had this problem a couple of years back and took the printer to a service company. They replaced the paper pickup rollers and I have not had the problem since. Other problems, yes, but not that problem.

I found the owners manual for your model, and it has detailed explanations of how to turn off the printing of the Startup page: This is where the owners manual is available online in .pdf format, at this URL: http://download.info.apple.com/Apple_Support_Area/Manuals/printers/0340211ALW12640UM.PDF Startup Page Info From your Owners Manual: (Yes, I've been reading the Manual for your printer. I have no life. :P ) From page 25 of the manual: "The printer takes a minute or two to warm up, and then it automatically prints a startup page. It prints the startup page every time you restart unless you turn the startup page off using either the Apple Printer Utility for the Mac OS or the Apple LaserWriter Utility for Windows. See Appendix A for details on these utilities." From page 249 of the manual: "Appendix A - Setting the Printer Default Settings" "Though the printer itself has no control panel, you can configure it by using programs on computers connected to the printer: - On Mac OS?based computers, use the Apple Printer Utility and the desktop printer?s setup function." So the answer is YES, you CAN setup the printer to not print the test page, but you have to use the setup utility on your computer to do so. Opening the Apple Printer Utility (From page 251) "The Apple Printer Utility has two windows: the Printer Selector window, which is similar to the Chooser, and the printer features window, which you use to view or change the printer?s settings." 1. Double-click the Apple Printer Utility. - The Installer puts the Apple Printer Utility in the Apple LaserWriter Software folder. You can move it wherever you like. 2. In the Printer Selector window, select and open the printer you want. - If the network has zones, click the zone where the printer is located. - Click the name of the printer you want. 3. Click Open Printer. - The printer feature window appears with the Printer Information category displayed. 4. To view or change settings under a category, click the arrow beside the category name to open the category and display its information and options. - Additional options may appear that you can also open and work with. When you are finished changing options in a particular category, you can click the arrow again to collapse the options. (NOTE: The option you want is "Startup Page".) 5. After viewing the information and making changes, click the Send button to send your changes to the printer. 6. Click the Close box to close the window. Turning the startup page on or off (From page 257) "The LaserWriter 12/640 PS normally prints a sample page when you turn the printer on. This page shows the printer?s name, the total number of pages printed, the amount of memory, installed options, and communication settings. You can turn this feature off if you wish. 1. Open the Startup Page category. - The Startup Page panel appears. 2. Click the checkbox to turn the startup page on or off. - When an X appears in the checkbox, the printer is set to print the startup page. 3. Click Send to send the startup page setting to the printer. That should remove the default printing of your startup page. HOWEVER, there is another possibility to affect a repair to your problem... As the paper-feed rollers get older, the rubber on the rollers gets slick and won't grip the paper anymore. Try buffing the rubber rollers with some fine sandpaper and see if that allows the machine to pick the paper up once again. If this is your problem, then you might make the lower-feed paper tray work again. Hope this helps, but let us know if you need more information to solve this problem. ;)
