Complaints about a printer's weight? Get a LaserWriter, which is over 4x heavier than the original ImageWriter, at a whopping 77lbs/35kg!

Fantastic! It's always nice to know there's one more working LaserWriter II in the world :)

You may want to read through my thread on when I fixed this exact issue with my LaserWriter II. Essentially, I replaced both C702 (a 10uF 50v capacitor) as well as the triac on that board. I replaced it with a Q6015L5TP and it worked great after doing that. I have seen other people say that...

I haven't bothered to replace the filter in my LaserWriter II. I don't have it on for long periods of time. However if you want to, I think that the HP part number you're looking for is the RF1-2130-CLN. The LaserWriter II uses a Canon SX engine, the same as the LaserJet II, so parts for that...

I've found that as I work on LaserWriters, I end up needing to take them apart and reassemble so often that I slowly stop needing to refer to the service manual every step. I try and still do so, because missing a step could be bad, but I could probably take apart a LWII to get to the paper...

The 4/600 is a Canon LBP-PX engine. If you google "Canon PX wiper blade" you'll find a few companies that claim to offer to have some in stock. Some may be telling the truth! I am still on the hunt for wiper blades for the LBP-CX engine, as used by the original LaserWriter. I found a company...

Did some more digging today, and found someone selling the board of a LaserWriter on ebay that has the LaserWriter 3.0 v47 1024k ROMs in it (342-0359-A, 342-0360-A, 342-0361-A, 342-0362-A). I'm tempted to get it to preserve those ROMs, but international shipping and imports is over $35 which...

There were quite a few ROMs made for the LaserWriter and LaserWriter Plus, each coming with a different version of PostScript, shown below. Thanks to Apple Tech Info article 10390, the LaserWriter ROMs section of BitSavers and the Apple Service Programs Manual for this info. Name ROM version...

Would anyone be willing to make some ROMs of the original (non-Plus) LaserWriter from @compu_85's dumps, and send them to me? I'd really like to downgrade my LaserWriter (which was an original, then upgraded to a Plus) to the original ROMs, but I don't have a rom flasher (and really would only...

That sounds like the correct power up procedure from my memory - it will spin but not latch. If you look in the service manual, there is a way to get it to print a "Service Test Page" - that will work regardless of the condition of the controller board. I’d recommend you try that, so you can...

I had a look at the Apple Service Source May 1993 (which is available to run in a browser the wonderful Archive.org Hypercard Stacks), and found (attached as images): a diagram that points out where the thermoprotector is located another troubleshooting step that involves inspecting the fuser...

Back when I did this on my LWII, I did replace the triac (Q6015L5TP) along with the cap, and that fixed it for me. The actual meaning of Error 50 is the fuser has failed to reach the temperature. More often than not, this is because of failed voltage reaching it, but it _could_ actually be the...

@croissantking - I may have a spare IIg board. I know I have three IINT boards, but I seem to remember having a IIg spare (that I recapped). I can have a look to see if I still have it if you want?

My first guess would be that the pick-up rollers are worn and no longer have enough grip to fully pick up the paper and feed it to where it should be. I've had this problem on the original LaserWriter, the II and the 16/600. To test this, try using the manual feed - if that works fine, then it's...

I saw that, but it's the actual upgrade kit - I'm trying to find the original non-plus ROMs. There was an upgrade kit on ebay in 2019 which had the original ROMs (presumably the owner had upgraded their LaserWriter, and then put the old ROMs in the box for safe-keeping) but they wouldn't ship it...
