This is printer-"not-connected" in view mode; [Up]
Date: Sun 23-Sep-1989 08:16:34 From: Unknown Subject: printer "not connected" After setting up my NeXT and connecting the laser printer, I tried to print a WriteNow file, only to receive the message that there was no printer connected to the Cube. I double checked the cables and power cord--everything was fine. But for some reason, the NeXT just won't recognize the presence of the printer (a NeXT laser printer, connected with NeXT cable). Is there something obvious I'm forgetting? The PrintManager panel lists the NeXT printer, and I have "chosen" it on the Print panel, but I still get the message "There is no printer connected to your local computer." Has anyone else had this problem?

It turned out that the problem was a blown fuse in the printer power supply. It blows if it sees a spike over 400 volts. I called NeXT & they explained how I could fix it myself. I did & it's fine. New printers have a better power supply, I'm told. The fuse is hidden next to the fan, approximately under the red 120/240v switch. You have to take off the plastic lid cover (3 unpotted screws on the underside of the lid), one in the center & 1 each on the sides. The lid pops off with a little tugging. Now you can open the lid all the way & reach the screws on the top back of the cover. Then the main cover comes off. There are 8 screws to remove, 2 on each side. Of these, 2 are inside (1 might be hidden by a green brush, if you have one), and 2 are inside the door on the back (hinge side). To get the 2 on the back, you have to remove the plastic door. Its hinges are flexible, they pop out easily. Don't forget the screw on the left end holding the plastic door to the roller assembly. The cover screw near the right hinge of the just-removed door should now be easy to get. Next you have to remove the cover protecting a connector on the left end that's blocking the last cover screw. The cover comes off straight up. It wasn't trivial, but I didn't have to force it anywhere. There are 4 screws holding in the fan. Take them out & there's the fuse. I ran out & bought 4 for $0.75 each. When reassembling, it's important to make sure the part of the cover that goes down inside the box, near the rollers, is to the outside of the alignment assembly. Look carefully before you take the cover off. There's a greasy place with a vertical black plastic tab parallel with the cover. The tab should be visible after the cover is replaced. Of course, I refuse to accept any blame if anyone reading this breaks their printer. I intentionally left out the rating of the fuse so you have to read it for yourself.

It's too bad that the fuse is not accessable without having to perform surgery. David's problem, however, may not be hardware related. Yesterday, or maybe it was the day before, two of our NeXTs forgot that they had printers. Things were working just fine, then they just forgot. Trying to print from WriteNow would cause a PostScript PrinterDevice (or some such) error. And yes, the correct printer (the only printer) was chosen. One of the NeXTs magically started to see its printer again without any intervention, and the other NeXT was brought back to reality by a reboot. Strange, eh? Mark >From: epsilon@wet.UUCP (Eric P.

It only started after we upgraded to 1.0. Now, magically, the print server will start complaining about "malformed postscript" (something about PrinterDevice), or printers will suddenly cease to exist. Anybody know what's going on?
